An article appeared a few days ago on New York Times signed by Jane E. Brody has shown how the incorrect nocturnal habits can affect our physical and mental health.
Research shows that the majority of people in need of 7 or 8 hours of sleep to act in an optimal manner. Failing to get enough sleep night after night, it can compromise your health and can even accorciarvi life. From childhood to seniority, the effects of inadequate sleep can have a profound effect on memory , learning , creativity , productivity , emotional stability and physical health .

According to sleep specialists of School of Medicine and Western Psychiatric Institute and Clinic s’ University of Pittsburgh a large number of organs and systems of our body are negatively affected by inadequate sleep: will suffer the heart, lungs and kidneys, appetite, metabolism and weight control, the immune system, pain sensitivity, reaction time, mood, brain function.
“ little sleep is also a risk factor for depression and substance abuse, especially among people with post-traumatic disorder ,” according Anne Germain , associate professor of psychiatry of ‘ University of Pittsburgh , “ latter tend to relive their trauma when they try to sleep, which keeps their brain in a state of alert. “
The elderly are particularly vulnerable. Timothy H. Monk , who heads the Human Chronobiology Research Program of Western Psychiatric Institute and Clinic of ‘ University of Pittsburgh , is the head of a federally funded study on circadian rhythms, the intensity of sleep, stress reactivity and brain function of the elderly. She discovered that many are helped by common remedies for insomnia, such as keeping a regular sleep schedule, avoiding naps in the late afternoon and caffeine, and reducing distractions such as light, noise and pets.
It should not be a surprise that a myriad of systems of our body can be damaged by short nights. “ Sleep affects almost every tissue in the body ,” says Dr. . Michael J. Twery , a sleep specialist of ‘ National Institute of Health U.S..
Many studies have linked insufficient sleep all ‘ weight gain . Staying awake at night increases the time available to consume food, and also the levels of Leptin , which tells the brain that enough food has been consumed, are lowest in those who sleep little, while Ghrelin levels , which stimulates the appetite, are higher.
Unfortunately, the body’s ability to process glucose is strongly conditioned, which can result in type 2 diabetes. In one study, healthy young men were deprived of sleep more than 4 hours a night for 6 nights in a row, and showed levels of insulin and blood sugar as those of people considered prediabetiche. The risk of cardiovascular disease and heart attacks are more in people who slept less than 6 hours a night. Even one night of inadequate sleep can cause high blood pressure constant throughout the day in people with hypertension. Another association is with coronary artery calcification.
A Japanese study of 24,000 women aged between 40 and 79 years found that color who slept less than 6 hours a night had more likely to develop breast cancer than women who slept more. The risk may result from decreased levels of melatonin, the sleep hormone. The connection between melatonin and breast cancer is the work of Eva S. Schernhammer of Harvard Medical School .
Even children can suffer hormonal changes because of lack of sleep. In fact, the ‘ growth hormone is released during deep sleep: this hormone not only stimulates growth but also stimulates the growth of muscle mass and repairs damaged cells, both in children and in adults. The dr. Vatsal G. Thakkar , a psychiatrist of New York University , recently associated with the lack of sleep to the erroneous diagnosis of attention deficit disorder and hyperactivity in children. In one study, 28% of children with sleep problems had symptoms of the syndrome but not the syndrome.
During sleep the body produces cytokine, a hormone cell that helps fight infections . So, who sleeps little is more vulnerable to common infections, such as colds and flu . In a study of 153 healthy men and women, Sheldon Cohen of Carnegie Mellon University has found that those who sleep less than 7 hours a night have a chance to 3 times higher than normal to develop cold symptoms when exposed to the virus, compared to those who sleep 8 hours or more.
About memory , learning , judgment and troubleshooting , during sleep the new notions are encoded by the brain, and sleep is absolutely necessary for the system to work properly and efficiently. People who are well rested, have more ability to learn and remember what they learned.
insufficient sleep slows down your thinking, it is more difficult to concentrate and pay attention . Think about what would happen if it has to do with a vehicle or a hazardous machinery. In tests at the helm, those who sleep poorly behave as if under the influence of alcohol, and there is no caffeine or fresh air that can mitigate its effects.
