The US National Sleep Organization (Yes, there is - The National Sleep Foundation - approx. Zozhnika) conducted a study, the results of which revealed that more and more people are sleeping less than 6 hours per day. 75% of respondents indicated that they are experiencing sleep problems a few times a week, and women experience them more often than men and often feeling sleepy during the day.
Sleep - against diseases
Another study conducted at the University of California in San Francisco found that People who sleep less than 6 hours at night, 4.2 times more likely to develop colds. However, those subjects who slept more than 6 but less than 7 hours - was not found an increased risk of colds.
Dr. Nathaniel Watson, president of the American Academy of Sleep Medicine commented on the research: "This study supports the view that sleep is as important as the a healthy diet and exercise... People should consider sleep as a means by which they will be able to achieve a healthy life, not as something that interferes with their other classes. "
Cold - it's the least of the evils with which you may encounter, experiencing lack of sleep regularly. US National Institutes of Health reports that the ongoing shortage of sleep is associated with an increased risk cardiovascular disease, kidney disease, high blood pressure, diabetes and even stroke.
What gives a person a dream
Doctors from Harvard University in Boston, there are the following reasons why we should not neglect sleep.
- Memory and ability to learn: Sleep helps the brain better remember new information. People who went to sleep after something taught, showed the best results in tests.
- The metabolism and the regulation of body weight: Those who for a long time very little sleep, runs the risk of getting fat. People who sleep enough, elevated levels of the hormone ghrelin, which is responsible for the feeling of hunger. Thus those who enough sleep - more prone to overeating.
- Security: A bad night's sleep increases fatigue during the day. As a result, people may suddenly fall asleep in those moments when it is completely unacceptable - for example, in driving time.
- Mood: Probably everyone noticed that after a hectic or insufficient sleep, we feel irritated, impatient and capricious. Even those things that we usually do with pleasure - after a bad dream, we do not want them to do. If sleep problems continue, the bad mood can develop into depression.
- heart Health: Serious sleep problems can contribute to levels of stress hormones, blood pressure and irregular heartbeat.

By the way, scientists from the University of Laval in Quebec (Canada) conducted a study in 2008, which resulted in it turned out that those who have enough sleep, was 27% more likely to recover by 5 kg over 6 years than those who slept 7-8 hours. In subjects who slept for too long, it was also 25% more likely to recover by 5 kg. Therefore, those who are most afraid of getting fat - here's another reason to sleep enough, but at the same time does not pour.
