Not only, that, sleep is actually an essential element that enables a person to achieve success in life, lose weight and prolong life. Many studies have found that sleep deprivation can lead to various health problems.
However, there are a lot of people underestimate his sleep habits, as reported by Fox News, Sein (03/12/2012) the following:
1. Underestimating hours of sleep
Everyone has different sleep long hours. However, some experts suggest as many as nine hours of sleep per day. Unfortunately, many people who experience chronic sleep deprivation or suffering from sleep disorders.
A survey found that most people with insomnia do activities that disturb one hour before going to bed, that watch TV, operate computer and perform household chores. That is, those activities likely to disturb sleep hours.
2. Lack or mostly sleeping
National Health Interview Survey in the U.S. found that adults who are used to sleeping less than six hours were more likely to smoke, alcoholism, lack of exercise, and obesity. Interestingly, adults who sleep more than nine hours do equally unhealthy behaviors.
Researchers from University College London found that lack of sleep increases or most of the risk of death by 2-fold. The scientists were sure why sleep deprivation is bad for the heart, but the cause why most sleep also has a similar effect remains a mystery.
3. Sleep is not in accordance with the movement of the sun.
Crypto chromes are proteins that are found in every living creature on earth. These proteins are sensitive to light dawn and dusk as well as affect the biological clock and is found in the eyes and skin. With this protein, the human body can detect sunlight even with your eyes closed.
Crypto chromes detect sunlight and reduced serotonin signaling modifier's pineal gland that makes up the mood of the day. It also increases the hormone melatonin that the body can rest well. This is what allows people wake up refreshed in the morning.
4. Sleeping with the lights on
Alternatively, sleep hormone melatonin is inhibited by light and will increase during the dark. The longer maintained, melatonin production will decline and be bad for mental and physical health. Research shows that aging was associated with lower levels of melatonin during sleep.
Melatonin is involved in learning and memory, as well as supposedly effective for treating Alzheimer's disease. This hormone is considered a powerful antioxidant that can protect DNA from free-radical damage and may prevent the development of some types of cancer.
5. Sleep less soundly
Chronic sleep deprivation can alter glucose metabolism. The body's ability to produce and respond to insulin would decline by about 30 percent, similar to the early signs of diabetes. Research has shown that the difficulty of deep sleep is also associated with hormonal disorders.
