The path to good sleep: effective habits and remedies based on science
The science of sleep: Let’s start with the basics
Sleep cycle and its importance
Sleep is an essential activity in our lives, and its cycles are broadly classified into two types: REM sleep and NREM sleep. NREM sleep is further divided into four stages depending on its depth, and REM sleep is known as dreaming sleep. This cycle is essential for physical and mental health and recovery, as well as playing an important role in learning and memory consolidation. For example, there is a process in which new information learned is organized and consolidated as memory during sleep. This is called “sleep-dependent memory consolidation,” and REM sleep is particularly important for this process.
Types and effects of sleep disorders
There are many types of sleep disorders, including insomnia, sleep apnea syndrome, REM sleep behavior disorder, and narcolepsy. These sleep disorders have the effect of significantly lowering the quality of life, such as excessive daytime sleepiness, decreased concentration, and decreased memory. In particular, sleep apnea syndrome is known to increase the risk of cardiovascular disease, and the importance of early detection and treatment of sleep disorders has been pointed out.
Sleep quality explained by psychology
In psychology, the quality of sleep is said to have a significant impact on subjective satisfaction and the state of mind and body the next day. To improve the quality of your sleep, it is effective to relax before bed, create a comfortable sleep environment, and maintain a regular daily rhythm. Additionally, psychotherapy, particularly cognitive behavioral therapy, has shown high effectiveness in treating insomnia and is an example of a psychological approach to improving sleep quality.
Sleep and health: deep relationship
Sleep and health are deeply related, and quality sleep is essential for maintaining physical and mental health. Even short-term sleep deprivation has been reported to cause a decline in cognitive function, emotional instability, and weakened immunity. Numerous studies have shown that long-term sleep deprivation increases the risk of obesity, diabetes, cardiovascular disease, and more. Sleep plays an important role in maintaining health, adjusting the body’s metabolism and hormone balance, and strengthening immune function.
Latest trends in sleep research
Sleep research has made great progress in recent years, with active development of sleep monitoring using wearable devices and new technologies to improve sleep quality. Research is also progressing to evaluate sleep quality using physiological indicators such as brain waves and heart rate, and there are expectations for personalized sleep improvement measures that will improve the quality of each individual’s sleep. These latest research trends have the potential to revolutionize the treatment and prevention of sleep disorders in the future.
Common factors that interfere with sleep
Stress and anxiety
Stress and anxiety are major causes of sleep disorders. Psychological research shows that stress activates the body’s alert system, causing the adrenal glands to secrete stress hormones such as cortisol. These hormones have the effect of keeping the body alert by increasing heart rate and blood pressure, which in turn interferes with sleep. People with anxiety disorders are especially likely to experience difficulty falling asleep and waking up during sleep.
Influence of lifestyle and environment
Daily lifestyle and living environment greatly affect the quality of sleep. For example, irregular life rhythms, lack of exercise, excessive caffeine intake, light and noise in the bedroom are factors that can worsen sleep. In particular, it is not recommended to use smartphones or computers before bed, as light suppresses melatonin secretion and disrupts the body’s internal clock.
Eating habits and sleep quality
Eating habits also have a big impact on sleep. It is known that eating a heavy dinner or consuming too much alcohol before bedtime can reduce the quality of your sleep. On the other hand, consuming foods containing nutrients that promote sleep, such as tryptophan, vitamin B6, and magnesium, can improve the quality of your sleep. Tryptophan is a precursor to melatonin, which promotes sleep, and bananas and milk are good examples.
Using digital devices
Excessive use of digital devices can contribute to sleep disorders. The blue light emitted by these devices specifically suppresses melatonin secretion and disrupts sleep rhythms. Also, using social media late at night and being exposed to exciting content can keep your brain in a state of excitement, making it difficult to relax and fall asleep.
Biological clock and the influence of light
The human body clock is roughly regulated on a 24-hour cycle, but this rhythm is influenced by external light. Natural light helps reset your body clock and regulate your sleep-wake cycle. However, artificial light, especially strong light at night, can disrupt the body’s internal clock, delay or suppress melatonin secretion, and induce sleep disorders. Therefore, creating a dark environment before bed is the key to a good night’s sleep.

Habits to achieve good quality sleep
Building the habit of going to bed and waking up on time
Human body clocks function optimally by maintaining a certain rhythm. Going to bed and waking up on time is the most basic way to adjust this internal clock and promote deep sleep. In fact, many studies have shown that following a consistent schedule can help you sleep better at night and improve your performance during the day. To develop this habit, it is recommended to wake up at the same time every day, including weekends.
Optimization of sleep environment
Adjusting your sleep environment is an important step to paving the way to good quality sleep. An ideal sleep environment means a quiet, dark, and cool space. In particular, the temperature of your bedroom has a big impact on your sleep quality. It is generally known that people sleep better in slightly cooler environments, and a temperature of around 18°C is recommended. Additionally, it is important to choose a comfortable mattress and pillow, which will reduce pain and discomfort in your body.
Stress management and relaxation techniques
The stress of daily life can greatly interfere with sleep. By effectively managing stress and utilizing relaxation techniques, you can relax your mind and body and improve the quality of your sleep. Things like meditation, deep breathing, and yoga are scientifically proven to reduce stress and help you sleep. In particular, relaxation exercises before bedtime can help you fall asleep more easily and promote deep sleep.
The role of proper diet and exercise
A balanced diet and regular exercise are essential elements for good quality sleep. In particular, it is recommended to avoid heavy meals before going to bed and eat light meals. Many studies have also shown that moderate exercise during the day improves the quality of your sleep at night. However, you should avoid strenuous exercise right before bedtime, and ideally you should finish exercising at least 3 hours before bedtime.
Routine before sleep
Establishing a pre-bedtime routine will help send a signal to your body and mind that it’s time for bed, leading you to sleep. For example, it’s important to get into the habit of relaxing activities, such as taking a warm bath, reading a book, or doing some light stretching. These activities calm the mind and body and promote deeper sleep. Finding a routine that suits your personal preferences and making it a nightly habit can help you get better quality sleep.
Improving sleep under certain circumstances
Shift work and jet lag
Shift work and jet lag disturb our body clock and greatly disrupt our sleep patterns. Shift workers are more likely to experience mismatches with their body clocks due to irregular working hours. To deal with this, light therapy and melatonin replacement therapy are said to be effective. On the other hand, for jet lag, it is recommended to gradually adapt to the destination time zone before traveling. Specifically, gradually shifting your body clock by going to bed early and waking up early can help.
Sleep during pregnancy
During pregnancy, many women experience a decline in sleep quality due to changes in hormonal balance, physical discomfort, and psychological stress. To improve your sleep during pregnancy, it’s important to use comfortable bedding and develop a relaxation routine before bed. Also, moderate exercise during the daytime has been shown to promote sleep, but care must be taken not to exercise too much.
Sleep quality in the elderly
As we get older, our sleep patterns change and it becomes difficult to get deep sleep. To improve sleep quality in older adults, it is important to be active during the day, go to bed on time, and optimize your sleep environment. It is also a good idea to avoid long naps and take short naps if necessary.
Sleep in children and adolescents
Children and adolescents need sufficient sleep for growth and development. However, school homework, smartphone use, and irregular sleep schedules leave many young people sleep deprived. As parents, limiting the use of electronic devices before bedtime and encouraging children to get into the habit of going to bed on time can help improve sleep quality.
Intervention and treatment of sleep disorders
There are various treatments for sleep disorders, but cognitive behavioral therapy is widely recognized to be particularly effective. This therapy focuses on correcting misguided beliefs and attitudes about sleep and reducing sleep stress. Short-term use of sleeping pills may also be considered if needed, but they are not recommended as a long-term solution.
