Good sleep and the right time for it are mandatory components in the daily routine of modern man. How many hours do you need to sleep?
Almost everyone will answer this differently. Indeed, at present, people are so busy that sometimes there is no time left for a full sleep. At the same time, they claim that they sleep five, well, or, in extreme cases, six hours a day and feel just fine. No fatigue, laziness or drowsiness. However, this is actually not the case. A lot of research has been done in different countries. As a result, it was found that people who slept regularly for 5 hours had lower mental and physical performance than those who slept for 8 hours.
Similar experiments, only with the participation of women, were put by scientists from British universities. They found that when resting less than 8 hours a day, the likelihood of heart disease increases. The reason lies in the production in the blood of a highly active protein that causes cardiovascular disease. At the same time, another protein begins to be produced in the body, which provokes inflammatory processes.
In general, by and large, there is no single exact number of how many hours you need to sleep. Depending on age categories, this indicator varies. So, for example, the smallest sleep at least 16 hours a day, preschool children - 11, schoolchildren - 10, adults - 8.
However, the quality of sleep is determined not only by its duration, but also by depth. Sleep is the time during which the body allows itself to completely relax, regain strength and stock up on energy for the next day. That is why how many hours you need to sleep, directly depends on how well you rested during the night. It was proved that night dreams indicate insufficient relaxation, because, perceiving vivid images and pictures, the brain continues to work actively. Accordingly, the rest of the body is less complete, and therefore in the morning I want to sleep longer.
When determining how much sleep is needed, physical and emotional stress should be considered. After an active day's work, you need to sleep until it completely rashes, i.e. to get up not by the alarm clock, but by yourself, when the body is completely ready for this. Emotional overloads also have a profound effect, especially on the nervous system, leading it to a state of stress. In this regard, there is even an opinion that the duration of sleep of women should be longer than that of men, because they are much more worried and "take everything to heart."
In order to get the maximum benefit and pleasure from sleep, experts at the University of Glasgow at Scotland share some tips:
1. As accurately as possible, calculate how many hours you need to sleep for you to wake up after the first ring of the alarm, and not to transfer it for 10 minutes several times. This is explained by the fact that interruption of sleep only worsens the general condition.
2. Waking up, you can look at bright colors for a few minutes, this will help to recharge your batteries. For this purpose, you can buy red, hot pink, orange or yellow bedding.
3. After waking up, you should not immediately get up and run to get ready, you can sit in a warm bed for a while, thinking about upcoming matters. By positively adjusting yourself, you can quickly cope with difficulties.
4. Fresh morning air works well, it helps to gain vigor and gain clarity of mind.
If, waking up in the morning, you feel fresh, awake and rested, then you slept exactly as much as you needed. Sleeping is characterized by laziness and irritability, and lack of sleep is characterized by a pronounced reluctance to get up.
