How many hours need to sleep for good health?

A good dream and the time correctly chosen for it are mandatory components in the daily routine of a modern person. How many hours need to sleep?

Almost everyone will answer this in different ways. After all, at the present time people are so busy that sometimes there is no time 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 great at the same time. No fatigue, sloth and drowsiness. However, in fact, this is not so. In many countries, many studies have been carried out. 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,put scientists of British universities. They found that resting less than 8 hours a day increases the likelihood of heart disease. The reason lies in the development in the blood of a highly active protein that causes cardiovascular diseases. At the same time, another protein provokes inflammatory processes in the body.

In general, by and large, there is no single accuratedigits how many hours you need to sleep. Depending on the age categories, this indicator varies. For example, the youngest sleep at least 16 hours a day, preschool - 11, schoolchildren - 10, adults - 8.

However, the quality of sleep is determined not only by itsduration, but also depth. Sleep - this is the time in which the body allows you to completely relax, restore strength and energy for the next day. That's why how many hours you need to sleep depends on how well you rested for the night. It was proved that night dreams indicate a lack of relaxation, since, perceiving bright images and pictures, the brain continues to work actively. Accordingly, the rest of the body - less than full, and therefore in the morning you want to sleep a little longer.

Determining how much to sleep, it should betake into account physical and emotional loads. After active daytime work, you need to sleep until you completely rinse, i.e. get up not on an alarm clock, but on your own, when the body is fully ready for it. Emotional overloads also have a strong effect, especially on the nervous system, causing it to become stressed. In this regard, there is even an opinion that the duration of sleep of women should be greater than that of men; they are much more experienced and "take everything to heart."

In order to get the maximum benefit from the sleep, the experts of the Scottish University of Glasgow share some tips:

1. Calculate exactly how many hours you need to sleep for you, to wake up after the first bell of the alarm clock, and not to translate it for 10 minutes several times. This is explained by the fact that interrupting sleep only worsens the general condition.

2. When you wake up, you can look at bright colors for a few minutes, this will help to recharge your energy. For this purpose, you can buy red, bright pink, orange or yellow bedding.

3. Do not wake up immediately after waking up and run off to gather, some time you can sit in a warm bed, thinking about the upcoming business. Positively adjusting yourself, you can quickly cope with difficulties.

4. Fresh morning air works well, it helps to get cheerful and get clarity of mind.

If you wake up in the morning, you feelfresh, vigorous and rested, it means that you slept exactly as much as you needed. Intermittent sleep is characterized by laziness and irritability, and lack of sleep is a pronounced reluctance to get up.
