So you can start your day in the best possible way!

Sleep Calculator

Studies have shown that many Germans do not get enough sleep. Some people don't know how much sleep they should get or simply don't schedule enough time for sleep. The sleep calculator helps you get your sleep on track. With the calculator, you can determine an optimal sleep schedule based on your individual situation, including your age and when you sleep or wake up. The sleep calculator is easy to use and helps you make sure you take enough time to rest.

When should I go to sleep?

The best time to go to sleep at night is a time frame where you can achieve the recommended amount of sleep for your age group.

You can figure out the best bedtime for your schedule based on when you need to get up in the morning and by counting backwards 7 hours (the recommended minimum per night for adults).

For example, if you have to get up at 6am, you should go to bed before 11pm.

It's equally important to find a regular sleep schedule that you can stick to every night - even on the weekends. If you stay up late on weekends and sleep in, it can be difficult for you to get back into a rhythm during the work week.

It is best to go to bed early every day and wake up early. However, this kind of sleeping rhythm is not suitable for everyone.

It is much more important that you get enough sleep, and quality sleep. You can do this by going to bed and getting up at the same time every day.

Please consult a doctor if you have trouble falling asleep at night or if you continue to be sleepy during the day despite a set bedtime. This could indicate problems with sleep quality that require further investigation.


Why is sufficient sleep so important?

Sleep is crucial for almost all areas of the body. If you get enough sleep every night, your body and mind can recover optimally and avoid the consequences of sleep deprivation.


What happens during sleep?

From the outside, every sleep may look the same, but in reality they are complex processes with four different phases that form a sleep cycle. In a typical night, a person goes through all four sleep stages several times in succession. The first three stages of the sleep cycle are known as non-rapid eye movement sleep (NREM). Stages 1 and 2 are lighter sleep stages in which the body and mind relax and calm down. Stage 3 is deep sleep, which is thought to be important for both physical and mental recovery. The fourth stage of sleep is rapid eye movement (REM) sleep. In this stage, most of the body is temporarily paralyzed, but brain activity increases dramatically and the eyes move rapidly behind closed eyelids.

During REM sleep, dreaming is most intense, which strengthens memory and complex thinking while awake. In the first sleep cycles of the night, more time is spent in NREM sleep. In the later sleep cycles, we experience more REM sleep. Researchers believe that the combination of NREM and REM sleep throughout the night ensures that we wake up refreshed both physically and mentally. If you don't get enough sleep, you don't go through these sleep cycles properly. Without the right balance of NREM and REM sleep, you won't get the rest you need, which can have far-reaching effects on your health and well-being.

Sleep cycles

The sleep cycle can be defined as an oscillation between non-REM (rapid eye movement) and REM sleep, both discussed below.

The sleep cycle is largely based on hormonal signals from the so-called internal clock (circadian clock). The circadian clock has a regular rhythm that corresponds with external signals (e.g. night/day) and can persist even if the external signals suddenly disappear. An example of this is jet lag, in which the body's circadian rhythm is disrupted by a long-distance trip, resulting in the traveler's inability to adjust to local time. The traveler then feels that it is either later or earlier than his body is used to, which affects his sleep.

Ideally, a person's sleep cycle follows the circadian clock, but sleep can be influenced by numerous factors, such as light, social timing (when others are awake, when work is due, etc.), naps, genetic factors, and more.

REM and non-REM sleep

During sleep, the brain uses significantly less energy than when awake, especially during non-REM (rapid eye movement) sleep. REM sleep is a form of sleep characterized by a number of aspects, including the eye movements for which it is named, the extensive paralysis of the body, and the occurrence of dreams. Non-REM and REM sleep are two very different categories of sleep.

Typically, the body alternates between non-REM and REM sleep over an average period of 90 minutes, which should occur 4-6 times in a good night's sleep. Non-REM sleep begins and eventually transitions into slow-wave or deep sleep. During this time, body temperature and heart rate drop, and the brain uses far less energy while it replenishes its supply of adenosine triphosphate (ATP), a molecule used to store and transport energy. During slow-wave sleep, growth hormones are also released, which are particularly important for human development.

REM sleep usually accounts for a smaller portion of sleep time and is best known for being accompanied by dreaming. Deprivation of REM sleep can lead to anxiety, irritability, hallucinations and difficulty concentrating. Studies have shown that when the body is deprived of REM sleep, it subsequently tries harder to get into REM sleep and the time spent in REM sleep is longer than during periods without sleep deprivation. This is referred to as REM rebound and is consistent with the assumption that REM sleep is necessary for the body. REM sleep, its effects, and its necessity are not yet fully understood. Although it is usually considered an important and necessary aspect of sleep, in some cases REM sleep deprivation can have temporary positive effects.

Sleep quality

Sleep quality can be measured by how difficult it is for a person to fall asleep and stay asleep through the night, and how often he or she wakes up in a single night. Sleep quality can also be measured subjectively by how rested a person feels after waking up.

Poor sleep quality disrupts the sleep cycle and the transitions between the different sleep stages. To achieve good sleep quality, the need for sleep must be aligned with the circadian rhythm of sleep. Ideally, the timing of sleep must be coordinated so that the maximum concentration of the hormone melatonin and the minimum core body temperature occur after the middle of the sleep phase and before waking.

What are the effects of sleep deprivation?

The effects of sleep deprivation can be felt in both the short and long term, affecting physical, emotional and cognitive health. Immediately after a night of poor sleep, one is more likely to lack energy during the day. One may be excessively sleepy during the day and have difficulty concentrating. You may doze off unexpectedly, which can be especially risky when driving. Even if one doesn't actually fall asleep, reaction time deteriorates, which can increase the risk of accidents. Lack of sleep is associated with irritability and mood problems. It can have a negative impact on thinking skills by deteriorating memory, decision-making and problem-solving abilities. As a result, there may be poorer academic performance or lower work productivity.

Lack of sleep can also impair physical performance and weaken the immune system, putting you at higher risk for infections. In the long term, lack of sleep is associated with a variety of health problems, including weight gain and obesity, diabetes, heart disease and other cardiovascular problems, depression and anxiety, pain, and hormonal imbalances. Studies have consistently found that sleep deprivation is associated with decreased quality of life and life satisfaction.


How to improve sleep and sleep hygiene

Improving sleep hygiene is a simple way to increase the likelihood of getting the sleep you need every night. To improve sleep hygiene, you need to revamp your habits and routines as well as your bedroom environment. The sleep calculator can help set a bedtime and wake-up time that ensures enough time is scheduled for sleep. The goal should be to stick to this schedule every day, including weekends and holidays. In addition to a set sleep schedule, there are other tips that can help ensure you get enough sleep:

  • A relaxing routine to get ready for bed
  • Avoiding caffeine and other stimulants in the afternoon and evening
  • Reducing alcohol consumption, especially in the hours before bedtime
  • Put away electronic devices, including cell phones and tablets, at least 30 minutes before going to bed
  • Find time for physical activity or sports during the day
  • As much natural light as possible during daylight hours
  • make the bedroom dark and quiet and/or use a sleep mask and earplugs to reduce disturbances
  • A good mattress and a comfortable pillow and bedding

Finding the right formula for sleep hygiene may take a little trial and error to figure out exactly what works for you. Starting with the sleep calculator and heeding other tips for a healthy sleep are sensible steps on the way to the sleep your body and mind need.


What is the biorhythm and how is it related to sleep?

Biorhythm refers to the natural, periodic fluctuations in physiological, psychological, and behavioral characteristics that occur in all living things and are controlled by the circadian rhythm. The circadian rhythm is an approximately 24-hour rhythm that influences various bodily functions such as the sleep-wake rhythm, hormone production, body temperature and metabolism.

The biorhythm has an important role in regulating the duration of sleep and the time of falling asleep. The circadian rhythm influences physical activity and wakefulness and is closely related to the sleep-wake rhythm. As a rule, the natural sleep rhythm is aligned with the circadian rhythm, so that one becomes tired in the evening and sleeps deeply at night. If the sleep-wake rhythm is disturbed, this can lead to sleep disorders, such as difficulty falling asleep, difficulty sleeping through the night or early waking.

The time it takes to fall asleep and the duration of deep sleep are also regulated by the hormones melatonin and cortisol, which in turn are influenced by the circadian rhythm. Melatonin is normally produced at night and signals the body that it is time to sleep. Cortisol, on the other hand, is produced in the morning and signals the body that it is time to wake up and become active.

It is therefore important to pay attention to the biorhythm and develop sleep habits that are aligned with the natural sleep rhythm. These include regular bedtimes, a pleasant sleeping environment and relaxation exercises to prepare the body and mind for sleep. If biorhythms are disrupted or sleep disturbances occur, it may be advisable to speak with a physician to investigate possible causes and discuss treatment options.


How much sleep do I need?

Sleep is far from being fully understood, and the amount of sleep a person needs can vary depending on certain parameters, such as age, and also quite individually. A person who gets enough sleep should not have daytime fatigue or dysfunction.

More generally, researchers have found that sleeping 6 to 7 hours a night correlates with a number of positive health outcomes, but there are many other factors that can influence those outcomes.

As people age, they tend to sleep less, with newborns sleeping significantly longer than adults. This discrepancy decreases with age, and sleep requirements equalize with those of adults from around the age of 5.


How much deep sleep does a person need?

Deep sleep is an important part of the sleep cycle that is crucial for a variety of physical and mental functions. It is the phase of sleep when the body recovers and regenerates the most. However, it is difficult to define an exact amount of deep sleep that each person needs, as it depends on several factors, such as age, gender, physical activity, and individual differences. In general, it is believed that adults should spend between 20% and 25% of their sleep in deep sleep, which is about 1.5 to 2 hours per night. During deep sleep, breathing, heart rate and blood pressure drop to a minimum to allow the body to recover and regenerate.

However, there is no magic number for the amount of deep sleep required, as everyone has different needs. For example, some people may need more deep sleep to recover after physical activity or strenuous work. Others may need less deep sleep to feel rested and refreshed. The best way to determine how much deep sleep you need is to listen to your body and see how you feel. If you feel rested and refreshed after a night of adequate deep sleep, you've probably gotten the right amount.

However, there are certain factors that affect deep sleep and can lead to a deficiency. These include sleep disorders such as sleep apnea and restless leg syndrome, alcohol and drug abuse, stress and depression. It is important to pay attention to these factors and seek medical treatment if necessary to improve deep sleep. Healthy deep sleep can lead to improved mental and physical health, including improved memory function, physical rest, and a strengthened immune system. Therefore, you should make sure to get enough deep sleep to promote your health and well-being.


At what point is one in deep sleep?

Deep sleep is an important phase of sleep during which the body regenerates and prepares for the next day. During deep sleep, bodily functions drop to a minimum and the body is the most difficult to wake up. As a rule, deep sleep occurs during the first half of the night, especially during the first two sleep cycles. However, it is difficult to determine an exact time from when one is in deep sleep, as this depends on various factors, such as individual sleep architecture and sleep rhythm.

An important indicator of deep sleep is the measurement of brain wave activity by electroencephalography (EEG). During deep sleep, brain waves are slower and higher in amplitude compared to wakefulness or other sleep phases. This is an indication that the body is in a phase of deep regeneration and recovery. However, it is important to note that brainwave activity can vary from person to person, and there are other factors that can affect deep sleep, such as sleep disorders or certain medications.

There are also physical signs that may indicate that you are in deep sleep. During deep sleep, muscle tone is reduced, which can make it difficult or impossible to move. In addition, breathing is slower and deeper, and pulse and blood pressure drop to a minimum. These physical changes are important indicators that the body is in a deep phase of sleep and is focused on recovery and regeneration. In summary, deep sleep is an important phase of sleep in which the body regenerates and renews itself. It is difficult to determine an exact time from when one is in deep sleep, as this depends on various factors, such as individual sleep architecture and sleep rhythm. However, there are certain physical signs and measurements such as EEG that can indicate that you are in deep sleep. If you are having trouble getting enough deep sleep, you should talk to a doctor to evaluate possible sleep disorders and discuss treatment options.


How can I tell if I was in deep sleep?

It can be difficult to tell exactly if you have been in deep sleep without tools. However, there are some physical signs that can indicate that one is in this stage of sleep. For example, one may be very difficult to wake up during deep sleep. So, if in the morning you feel that you slept very deeply and you can't remember well whether you woke up several times or how long you lay awake, this could be an indication that you were in deep sleep.

Another way to detect deep sleep is to monitor your own sleep patterns with a sleep app or fitness tracker that can measure sleep phases. These devices typically use sensors to monitor movement and breathing during sleep and use this to calculate sleep cycles and sleep phases. By collecting data over time, you can get an overview of your sleep patterns and frequency of deep sleep.

Another way to promote and recognize deep sleep is to create a sleep environment that is conducive to deep and restful sleep. This includes, among other things, a comfortable bed and a quiet and dark sleeping environment. If you feel rested and refreshed the next morning, this is another indication that you have had sufficient deep sleep.

However, it is important to note that it is difficult to accurately determine deep sleep without measuring devices. If you suspect that you are not getting enough deep sleep or are having difficulty getting into deep sleep, it is advisable to talk to a doctor to investigate possible sleep disorders and discuss treatment options.


Sleep requirement by gender 

There are some studies that suggest that there are differences in sleep requirements between the sexes. However, the results are not conclusive and more research is needed to understand these differences in more detail.

Some studies have shown that women generally need longer sleep than men. For example, one study found that, on average, women need about 30 minutes more sleep per night than men. However, other studies have found no significant differences in sleep requirements between the sexes.

There is also research to suggest that women generally sleep worse than men. Women are more likely to report sleep disorders such as insomnia, nightmares, and poor sleep quality compared to men. Some research suggests that this may be due to biological differences, such as hormonal changes during the menstrual cycle or pregnancy.

However, it is important to note that sleep need and quality are very individual and depend on many factors, such as age, physical activity, diet, stress level and other factors. Thus, it is not useful to make gender generalizations when it comes to individual sleep needs. Everyone has different sleep needs and it is important to pay attention to your own needs and signals from your body in order to get an adequate and healthy amount of sleep.


Sleep requirements by age

Here is a detailed list of sleep needs by age:

  • Newborns (0-3 months): 14-17 hours of sleep per day, including naps during the day.

  • Infants (4-11 months): 12-15 hours of sleep per day, including naps during the day.

  • Infants (1-2 years): 11-14 hours of sleep per day, including a nap during the day.

  • Preschoolers (3-5 years): 10-13 hours of sleep per day, including a nap during the day.

  • School children (6-13 years): 9-11 hours of sleep per day.

  • Adolescents (14-17 years): 8-10 hours of sleep per day.

  • Adults (18-64 years): 7-9 hours of sleep per day.

  • Older adults (over 65 years): 7-8 hours of sleep per day.

It is important to note that these are general guidelines and that actual sleep needs may vary from person to person. Some people may need more or less sleep than the averages listed here. It's also important to note that it's not just the amount of sleep you get, but also the quality of sleep that's important to feeling rested and refreshed. If you have trouble falling asleep or staying asleep through the night, you should talk to a doctor to evaluate possible sleep disorders and discuss treatment options.


What is the optimal duration of the nap?

The nap, also known as a siesta, is a short rest period practiced in many cultures around the world. A nap can help increase physical and mental performance, improve concentration, and elevate mood. However, the question often arises as to how long an afternoon nap should ideally last in order to achieve maximum effect.

Generally, a nap can last between 10 and 30 minutes, 60 minutes or 90 minutes. The duration of the nap depends on several factors, such as individual sleep needs, physical activity and time of day.

A short nap of 10 to 30 minutes is called a power nap and can help improve cognitive performance and alertness. Powernaps can also help fight fatigue during the day and relax the body. However, power naps should not last longer than 30 minutes, otherwise a so-called sleep inertia effect occurs, in which the body needs some time after waking up to return to a state of wakefulness.

A nap of 60 minutes can help to increase physical and mental performance. Such a nap leads to entering a deep sleep phase in which the body can recover and regenerate. The body can also begin to reduce the stress hormone cortisol during this time, which can help improve mood and reduce stress.

A long nap of 90 minutes can also provide many benefits. During such a nap, one goes through all phases of the sleep cycle, including the deep sleep phase and the REM sleep phase. REM sleep is particularly important for cognitive performance and memory. A long nap can also help strengthen the immune system and improve physical health.


Why should the nap not be longer than 90 minutes?

A 90-minute nap is often considered optimal because it goes through all phases of the sleep cycle, including deep sleep and REM sleep. Deep sleep is important for the body's regeneration, while REM sleep is essential for cognitive performance and memory. A long nap can also help strengthen the immune system and improve physical health.

However, it is recommended that a nap should not last longer than 90 minutes, otherwise a so-called sleep inertia effect can occur. This means that the body needs some time after waking up to get back into a state of wakefulness. During this time, sleepiness, confusion and reduced performance can become apparent.

A long nap can also interfere with normal nighttime sleep if it occurs too late in the day. For example, taking a long nap towards evening or in the early evening can mean that you are not tired in the evening and it becomes more difficult to fall asleep or sleep through the night.

It is also important to note that the optimal length of nap may vary from person to person. Some people may only need a short power nap to improve their cognitive performance and concentration, while others may need a longer nap to fully recover. It is important to listen to your body and adjust the length of your nap accordingly.

Regardless of the duration of the nap, there are some tips that can help to have a restful nap. It is important to create a comfortable sleeping environment, for example, by darkening the room and finding a comfortable position. Also, one should be careful not to eat too much or too heavy before going to sleep, as this can affect digestion and sleep. Finally, care should be taken not to nap too late in the day, as this can interfere with normal nighttime sleep.

Overall, a nap can help boost physical and mental performance and improve mood. 


The sleep rhythm - what is it?

You know this for sure: Sometimes you sleep well and refreshed, sometimes badly and restless. This is often related to your sleep rhythm. In this article, you will learn everything you need to know about the topic of sleep rhythm: What it is, where the word comes from, how you can influence it and whether it's healthy at all. In addition, we will take a look at the different sleep rhythms that exist. Be curious and dive into the world of sleep!

Before we go into depth, let's first clarify what is meant by a sleep rhythm. Basically, it is the sequence of sleeping and waking phases that your body goes through in the course of a day. These rhythms are biologically anchored and based on your inner clock. They help you to be awake and alert during the day and to rest at night.

The concept of sleep rhythm

The word sleep rhythm is made up of the two parts "sleep" and "rhythm". "Sleep" refers to the state of physical and mental rest you are in when you are asleep. "Rhythm," in turn, comes from the Greek and means "flow" or "beat." The sleep rhythm therefore describes the regular sequence of sleeping and waking phases in your life.

How you can influence your sleep rhythm

There are various ways in which you can influence and optimize your sleep rhythm. Below we present some tips and tricks that can help you sleep better and find your rhythm:

  1. Regular sleeping hours: Try to go to bed and get up at the same time every day - even on weekends. This way, your body gets used to fixed times and finds its natural rhythm more easily.

  2. Relaxing evening routine: Make your evening calm and relaxed. Refrain from stimulating activities such as sports or exciting movies just before bedtime. Instead, relaxation exercises, meditation or a warm bath can help you wind down.

  3. Sleeping environment: Make sure your bedroom is cool, dark and quiet. Ban electronic devices and ensure a comfortable room temperature of about 18 degrees Celsius.

  4. Diet: Avoid heavy, fatty meals in the evening and reduce your caffeine and alcohol intake. These can disrupt your sleep rhythm and affect sleep quality.

Is it healthy to influence the sleep rhythm?

Basically, influencing sleep patterns can be healthy, especially when it comes to correcting bad sleep habits and improving sleep quality. A healthy sleep rhythm can increase your well-being and quality of life by helping you start the day rested and full of energy. 

However, you should be careful not to manipulate your sleep rhythm against your body's natural needs. Too much interference with your natural rhythm can lead to sleep disorders and other health problems. This applies, for example, to shift work, jet lag or extreme sleep experiments in which the sleep rhythm is artificially shortened or lengthened.

The different sleep rhythms

There are different sleep rhythms, which differ from each other in duration and structure. Here are some of the best known:

  1. Monophasic sleep: This is the most widespread sleep rhythm in our society. It consists of a single sleep phase of about seven to nine hours per night.

  2. Biphasic sleep: In biphasic sleep, sleep is divided into two phases: a main phase at night and a shorter siesta in the afternoon. In some cultures, this is the usual sleep rhythm.

  3. Polyphasic sleep: Polyphasic sleep consists of several short sleep phases spread throughout the day. There are different variants such as "everyman" sleep (a longer core sleep and several short naps) or "uberman" sleep (exclusively short naps at intervals of about four hours). However, these sleep patterns are not practical for most people and can lead to health problems in the long run.

Your sleep rhythm is an essential part of your well-being and health. By taking care of regular sleep times, a relaxing evening routine, a pleasant sleep environment and a balanced diet, you can positively influence your sleep rhythm and improve your sleep quality.

However, it is important that you do not manipulate your natural sleep rhythm too much or work against your body's own needs. Instead, make sure to give your body the rest and recovery it needs to stay healthy and productive.

Finding the right sleep rhythm

Finding an appropriate sleep rhythm is one of the most important ways to promote restful and healthy sleep. A regular sleep rhythm can help improve sleep quality, organize your daily routine, and promote physical and mental health. In this article you will learn how to find your right sleep rhythm.

  1. Create a sleep schedule
    A sleep schedule can help establish a regular sleep pattern. Set fixed bedtimes and wake-up times that you keep most days of the week. You should also try to keep the same bedtime and wake-up time on weekends and holidays.

  2. Pay attention to your chronotype
    Every person has an individual chronotype, which determines whether you are more of an early riser or a night person. The chronotype can also change in the course of life. Pay attention to your chronotype and adjust your sleep rhythm accordingly.

  3. Consider your sleep needs
    Sleep needs vary from person to person and can also fluctuate throughout life. Consider your individual sleep needs and make sure to get enough sleep. The National Sleep Foundation recommends adults ages 18 to 64 get seven to nine hours of sleep per night.

  4. Create a good sleep environment
    Create a sleep environment that invites sleep. A quiet, dark and cool sleeping environment can help improve sleep. A comfortable bed and a suitable mattress can also help you sleep better.

  5. Avoid sleep disturbances
    Sleep disturbances can disrupt sleep and lead to disruption of sleep patterns. Avoid caffeine, alcohol and nicotine before bed. Screen time should also be avoided in the last few hours before bedtime.

  6. Respect your physical and mental needs
    Your sleep schedule should also be adjusted to your physical and mental needs. If you are physically or mentally active, it can be helpful to go to bed a little earlier and sleep a little longer.

Overall, there are many factors that can influence sleep patterns. By creating a sleep schedule, taking into account your chronotype, your sleep needs, creating a comfortable sleep environment, avoiding sleep disorders, and paying attention to your physical and mental needs, you can find your right sleep rhythm and have a restful night.


What does the word chronotype mean?

The word "chronotype" is composed of the Greek words "chronos" (time) and "typos" (type). It thus describes a person's individual type or preference regarding their natural sleep-wake rhythm and their activity and energy levels throughout the day. Chronotype is an important component of the body's circadian rhythm, which controls the body's natural 24-hour cycle and is influenced by factors such as light, darkness, food intake and other environmental factors.


What is a chronotype in relation to sleep?

A chronotype refers to a person's individual preference regarding their natural sleep-wake rhythm and biological clock. There are people who naturally tend to get up early and go to bed early, while there are others who are more alert at night and tend to go to bed late and get up later accordingly.

These individual differences are called chronotypes, and they are the result of several factors, including genetic predisposition, age, gender, lifestyle, and environmental factors. Most people can be categorized into one of three chronotypes: Early risers (Larks), Late risers (Owls), or people who fall between the two extremes (Middle type).

Larks tend to go to bed early and get up early. They have more energy in the morning and feel most productive during the day. Owls, on the other hand, tend to go to bed later and get up later. They feel most productive in the evening and have difficulty getting up early and being productive if they have to get up too early. The middle type is a mixture of both and shows no clear preference for early or late rising.

Science has shown that a person's chronotype affects not only their sleep habits, but also their physical and mental health, as well as their performance in daily life. People who go against their natural inclination may have difficulty getting adequate sleep, which can lead to sleep disorders, fatigue, mood swings and other health problems.

Overall, it is important to understand that chronotypes are individual and that there is no "right" or "wrong" preference. People should try to adjust their sleep habits to their natural inclination to ensure optimal health and performance.


How can I find out which chronotype I am?

There are several ways to find out what chronotype you are. Here are some suggestions:

  1. Observe your natural sleeping and waking habits. If you feel well-rested and refreshed without an alarm clock at a certain time in the morning, you are probably an early riser. If, on the other hand, you have trouble getting up early and feel most productive in the evening, you are probably a late riser.

  2. Keep a sleep diary. Note when you go to bed, when you get up, and how you feel when you wake up. This way you can better understand your sleep patterns and energy levels and identify your chronotype.

  3. Take an online test. There are many free online tests that can help you determine your chronotype. These tests are based on questions about your sleeping and waking habits, your energy levels, and other factors.

  4. Consult a doctor or sleep specialist. If you have difficulty determining your chronotype or are having sleep problems, a doctor or sleep specialist can help you analyze your sleep patterns and make recommendations on how to improve your sleep.

It is important to note that chronotypes are on a spectrum and that many people can have characteristics of different chronotypes. Therefore, it is best to monitor your sleep habits regularly and focus on your body to determine which sleep and wake habits are best for you.


Can I change my chronotype?

Basically, it is difficult to change the chronotype because it is largely determined by the body's biological clock. The chronotype is genetically determined and is influenced by external factors such as light and darkness, which control the body's internal clock.

However, certain measures can help regulate sleep-wake cycles and promote healthy sleep hygiene. These include, for example:

  1. Regular bedtimes: Try to go to bed and get up at the same time every day to get your body used to a certain rhythm.

  2. Exposure to light: Sufficient daylight during the day and darkness during the night can help regulate sleep-wake cycles.

  3. Avoid stimulants: reduce consumption of caffeine and other stimulants that can interfere with sleep.

  4. Regular exercise: Physical activity can help improve sleep and naturally tire the body.

It is important to note that it may take some time for the body to adjust to new sleep habits. If you have difficulty regulating your sleep-wake cycle, it may be helpful to consult a doctor or sleep specialist who can make individual recommendations.


With this in mind,
Sleep well!
