Some believe that the key to good sleep is its duration. That is, it doesn’t matter if you went to bed at 11 p.m. and got up at 7 a.m. or if you fell asleep only at 3 a.m. and woke up at 10 a.m. because the set minimum sleep of 7 hours was fulfilled. But this is a fallacy.
The melatonin hormone is responsible for regulating the sleep and wake cycle in our body. Waking up when it is light, falling asleep when it is dark is a natural pattern for a person to sleep, but only recently scientists have found out why our body reacts to light in this way. Healthy sleep reduces the risk of so many diseases: obesity, immunity disorders, cardiovascular diseases.
The brain is a computer. The brain does not sleep, and it sometimes works more actively in a fast
sleep than during the wakeful period.
Benefits of Proper Sleep:
All living organisms on the planet live according to the laws of nature, and human being is no exception. Perfectly, you need to wake up at sunrise, but you need to go to bed at 21:00 for this.
Everyone who wakes up early goes to bed early. The human body is a complex system that functions during hours of wakefulness and sleep. The endocrine system produces the hormone melatonin from 22:00 to 2 a.m., and it is synthesized only during sleep. This hormone is responsible for:
- youthfulness;
- cell renewal and division;
- good mood;
- immunity work.
At the same time, the somatotropin hormone is produced. It is responsible for growth, weight loss, and overall health.

The Amount and Quality of Sleep Affect Our Ability to Absorb and Process Information

Lack of sleep reduces attention, ability to concentrate, the amount of working memory. Recent
studies have found a relation between sleep and concentration.
When you go to bed after 23:30, this affects the attention concentration for the next day, even if you have slept the recommended 8 hours. Go to bed earlier to be more productive. Do not forget that the quality of sleep is
influenced not only by the general atmosphere but also by sleeping accessories, which can be selected using the beautyrest mattress review.
Lack of Sleep Makes Mood Unstable
Studies show: lack of sleep leads to irritability and sudden changes in the emotional state, it is more difficult for a person to cope with stress. And if you do not get enough sleep regularly and systematically, it becomes very difficult for the nervous system — such experiments on yourself
can lead to increased anxiety and depression.
Skin Condition
Sleep restores damage that occurs in the skin cells, but not any sleep. Even if you sleep for a long time, but stay up late, the recovery function will not work fully. Pay attention to the fact that people who stay up late have more dull skin.
Lack of Sleep Affects Memory

In his book Organized Mind, Daniel Levitin explains how much sleep is necessary to consolidate memory. If you do not sleep until three at night, then everything you’ve learned during the
previous day starts being forgotten at a certain point.
Lack of Sleep Weakens the Immune System
If you sleep only 4 hours in one night, your immune system weakens (up to 70%). It is becoming increasingly difficult for the body to absorb carbohydrates. In one experiment, blood samples of the sugar content were taken from young men sleeping four hours in a row for six consecutive nights. This indicator was comparable to the norm for people with diabetes, and by the end of the study, their condition could be classified as prediabetic.
Those Who Sleep Little Time is Gaining Excess Weight Faster
There have already been many studies on this subject, but one of the most obvious, extensive and evidence-based ones is the American study of 70 thousand nurses, conducted over 16 years.
Result: women who slept less than 5 hours gained a lot of weight. And not because they ate more - it turned out that they eat even less than those who sleep the prescribed 8 hours. Scientists have concluded that lack of sleep probably affects metabolic rate.
Irritability and Bad Mood

As you know, lack of sleep affects our behavior. The sooner we go to bed, the less irritable, vulnerable and aggressive we will be. Falling asleep early will help us avoid negative thoughts
that undermine our inner balance.
