Sleep is necessary for a full life, which includes study, work, and many other activities. To restore our nervous system, to replenish its energy reserves, to normalize various biochemical and metabolic processes, quality sleep is a must.
Sleep and its importance to human health
To perform their daily duties fruitfully, to be active, to have good health, a person needs a good night's sleep at the right time. After all, the first sign that a person is overworked, and in his body there was some failure is the appearance of sleepiness. He feels constantly tired, completely unrested. This condition makes it difficult to get a good night's rest, which leads to the closure of the circle: the person becomes more and more tired.
Sleep disorders, in one form or another, affect quite a large number of people.
Every fourth person nowadays goes to a specialist with a complaint about their sleep. More and more often people resort to various remedies for sleep disorders, such as: pills, various syrups, sedatives. But often the cause of sleep disorders is psycho-emotional, and could be eliminated by working with a psychotherapist.
Not only adults suffer from such disorders, children are also prone to them, especially if their daily routine is violated, if they are too fond of computer games, or if the study load is too heavy.
As we know, a person usually spends a third of his life sleeping, which is quite a lot. How much time does a person really need for sleep? At different ages, this figure may differ. For example, a newborn baby sleeps almost all day, preschool children 13-14 hours, schoolchildren - about 8-10 hours. Adults need at least 7 hours to feel well. There is an individual norm of sleep for each person, and for some it may differ. As we know, there were people like Napoleon, who needed only a nap to feel rested.
What processes occur in the body during sleep
Every person at least once in their life has wondered, what happens to them during sleep? And how different is sleeping from being awake? To have a good rest, our body needs to be relaxed during sleep. To do this, it must be in a comfortable position, lying down. After all, it is the position of lying down gives our muscles back and neck the opportunity to relax completely. It happens that a person falls asleep in other uncomfortable positions. But after sleeping time spent in such positions, a person is unlikely to feel rested. While he slept, his back and neck did not feel supported, the joints in his spine clenched, and upon awakening, the person will feel pain in the lower neck and back.
If the sleeper lifts his arm and lets it go, the arm will fall down absolutely involuntarily. This indicates that our muscles are completely relaxed in our sleep.
During sleep, blood still continues to circulate in the body, but the heart rate and blood flow slows down. Body temperature drops a degree, breathing slows down and becomes deeper. Oddly enough, the human stomach works in daytime mode during sleep.
The same sensitivity to temperature changes remains during sleep. If he lies uncovered in his sleep and the temperature in the room drops below 26 degrees Celsius, the person will wake up. The same will happen when the temperature rises above 37°C.
So what happens to our brain when we sleep? According to scientists, the brain also continues to function, but the nature of the activity changes. The brain does not take in external information, but is busy processing and classifying the information it receives during the day. It compares it with the information that already exists and sends it for storage in the right cell of its memory. If a person is without sleep for a long time, he may experience memory impairment.
Interrupted sleep man at night: first aid in the morning to keep awake
There are enough reasons that can disrupt a person's sleep. These are loud noises, neighbors who decided to make noise, a woken child, an unexpectedly prolonged meeting with friends. A person's sleep can be greatly influenced by his or her well-being. But one way or another, it is necessary to look awake in the morning. There are several ways that can be the very first help to stay awake in the morning:
Postponing waking up for a while longer and promising yourself at least 5 more extra minutes in bed, can only bring more feelings of fatigue and irritation. After all, the body prepares for awakening in advance, and by postponing it, you give your brain a signal to sink back into the deep phase of sleep, taking away your energy for a brisk start to the day.
The most tempting prospect for the sleep-deprived person is to make himself a big cup of coffee. But take your time. It is worth remembering that the daily dose of caffeine for humans is 400 mg. Coffee can cause palpitations, headaches, and even a panic attack. It will take quite a long time to eliminate caffeine from the body, so you should not drink coffee in the evening if you do not want to get another sleepless night.
Be sure to eat breakfast, because breakfast will send a signal to your brain that it is time to wake up and give you more energy.
If you have a lot of things planned for the day, do the most important and difficult ones in the morning, because then the strength will decrease and the attention will dissipate.
You should make yourself do a light workout. It will help to partially overcome fatigue, improve circulation and, at least, lift your spirits.
And it's worth remembering that for quality sleep a person should, at least an hour before that to finish working with the computer, tablet, stop watching TV, to give the brain an opportunity to tune in to a good, sound sleep. It is better to listen to calm, pleasant music, read a good book.
