We need sleep for a full life, in which there is a place for study, work, and many other types of activity. In order to restore our nervous system, replenish its energy reserves, bring various biochemical and metabolic processes back to normal, quality sleep is simply necessary.
Sleep and its importance for human health
In order to fruitfully fulfill their daily duties, to be active, to have good health, a person needs good sleep at the time set for this. After all, the first sign that a person is overtired, and some kind of failure has occurred in his body, is the appearance of drowsiness. He feels constantly tired, completely unrested. This condition makes it difficult to get a quality rest at night, which leads to a closing of the circle: the person becomes more and more tired.
Sleep disorders, in one form or another, affect a fairly large number of people.
One in four people now visit a specialist with a complaint about their sleep. Increasingly, people are resorting to various means of 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 susceptible to them, especially if their daily routine is violated, if they are excessively fond of computer games, or if they have an unbearable academic load.
As we know, a person usually spends a third of his life in a dream, which is quite a lot. How much time does a person really need to sleep? At different ages, this figure may differ. For example, a newborn sleeps almost the whole day, preschool children 13–14 hours, schoolchildren — about 8–10 hours. Adults need at least 7 hours to feel good. Each person has their own individual sleep rate, and for some it may differ. As we know, there were people like Napoleon who needed just a nap to feel refreshed.
What processes occur in the body during sleep
Every person at least once in his life wondered what happens to him during sleep? And how different is a person when he sleeps from a person in the waking state? In order for rest to be complete, our body must be relaxed during sleep. To do this, it must be in a comfortable position, lying down. After all, it is the lying position that gives our back and neck muscles the opportunity to completely relax. It happens that a person falls asleep in other uncomfortable positions. But after a sleep time spent in such positions, a person is unlikely to feel rested. While he slept, his back and neck did not feel support, the joints in the spine were compressed, and after waking up, the person will feel pain in the lower neck and back.
If the sleeping person raises his hand and releases it, then the hand will absolutely limply fall down. This indicates the complete relaxation of our muscles in a dream.
During sleep, the blood still continues to circulate in the body, but the heartbeat and blood flow slow down. Body temperature drops by one degree, breathing slows down and becomes deeper. Oddly enough, the human stomach in a dream works in the daytime mode.
During sleep, a person remains the same sensitivity to temperature changes. If he lies open in a dream, and the temperature in the room drops below 26 ° C, then the person will wake up. The same will happen when the temperature rises above 37°C.
What happens to our brain when we sleep? According to scientists, the brain also continues to function, only the nature of activity changes. He does not perceive external information, but is busy processing and classifying information received during the day. It compares it with the information that already exists and sends it for storage to the desired cell in its memory. If a person is without sleep for a long time, he may experience memory impairment.
Interrupted human sleep at night: first aid in the morning to maintain vigor
There are enough reasons that can disturb a person’s sleep. These are loud sounds, neighbors who decided to make some noise, a child who woke up, an unexpectedly protracted meeting with friends. A person’s well-being can have a great influence on a person’s sleep. But, one way or another, in the morning you need to look cheerful. There are several ways that can be a real first aid for staying alert in the morning:
- Postponing waking up for a while longer and promising yourself at least 5 extra minutes in bed can only bring more feelings of fatigue and irritation. After all, the body prepares for awakening in advance and, delaying the moment, you give the brain a signal to plunge into the deep phase of sleep again, taking away your strength for a vigorous start to the day.
- The most tempting prospect for a sleepy person is to make himself a mug of coffee, but more. But take your time. It is worth remembering that the daily dose of caffeine for a person is 400 mg. Coffee can cause heart palpitations, headaches, and even panic attacks. It takes a long time to get the caffeine out of your body, so don’t drink coffee in the evening unless you want another sleepless night.
- Be sure to have breakfast, as breakfast will send a signal to the brain that it’s time to wake up and give an extra portion of vigor.
- If you have a lot of things planned for the day, do the most important and difficult in the morning, because then your strength will decrease and your attention will scatter.
- You need to force yourself to do a light workout. It will help to partially overcome fatigue, improve blood circulation and, at a minimum, cheer you up.
And it is worth remembering that for a person to have a good sleep, it is necessary to stop working with a computer, tablet, stop watching TV at least an hour before, to allow the brain to tune in to a good, sound sleep. It is better to listen to calm, pleasant music, read a good book.
