Sleeping is Necessary

Earlier I have shared the importance of sleeping in my post and now I'm going to talk about the problems you may face if do not sleep. Let us begin to read some serious facts, diseases, problems and cause and please don't sleep while reading.

Sleep is crucial to maintain one's health. Without it, we increase our susceptibility to an astonishing array of health problems, including heart diseases, stroke, diabetes, obesity and depression. 

Not sleeping enough can compromise your immune system, says Stanley Coren, noted professor of psychology and author of the very popular book, 'Sleep Thieves". You eat well and exercise in order to keep your immune system up, Coren goes on to explain, but if aren't sleeping, you undo all that good work. "the immune system works best when you are sleeping," he says. "That's when your natural killer cells are generated." Natural Killer Cells are produced in the bone marrow and found in the blood and lymph fluid. They are part of the body's defense mechanism against viruses, bacteria, even cancer, and they do not work properly in the persons who are sleep deprived. A study in Turkey revealed that after 24 hours of sleep deprivation, the percentage of natural killer cells in the blood declined by 37 percent. Another sleep deprivation reduced natural-killer-cell activity to 72 percent of normal levels. Though their activity returns to normal when we begin to get proper sleep, the real problem is that a lot of damage might have been done to our bodies when we were sleep deprived for several nights and our immune system might have left us undefended and susceptible to infection.

it's not just our immune system that gets adversely affected when we cut down on sleep. According to Dr. Michael Sole, a Canadian cardiologist, there is a higher rate of heart failure among people wit the sleep disorders and sleep disturbances. He goes goes to emphasis that there is increased evidence of C-reactive protein, an indicator of the heart disease risk, in people suffering from sleep loss.

Researches in various universities all over the world have discovered that chronic sleep loss can reduce the body's ability to regulate hormones and process carbohydrates. In a study at the University of Chicago, the researchers reduced participant's sleep from eight to four hours a night and after less than a week, they noted changes in the body similar to the effects of early diabetes or advanced aging. Sleep disturbances increase the likelihood of prediabetic state of glucose intolerance and insulin resistance. Both these are also markers for heart ailments. Dietician Ramona Josephson notes that insufficient sleep may affect three hormones that can contribute to obesity.

There's a decrease in leptin, the appetite-suppressing hormone found in our fat tissue, she says. Ghrelin, the hormone controlling hunger pangs increase with lack of sleep causing greater feelings of hunger. then a sleep deprived body starts producing more of the stress hormone cortisol, which increases fat storage.  Not only do the increased  hormones resulting from sleep loss make us eat more, but induces us to quickly or mindlessly make wrong food choice because we feel fatigued and week. "The less you sleep, the more your chances of obesity." Josephson concludes.

Sleep is important in keeping not only our waistline trim, but ensuring a balanced brain activity too. During sleep, brain neurotransmitters-the chemical that deliver messages between nerve cells in the brain are replenished. When we do not sleep well, our brain chemical become depleted which leads to emotional disturbances like depression, anxiety and general feelings of sadness, anger and irritation.

Now, what we have learnt?

Sleeping is necessary and if not sleep we can be in great trouble . So, keep sleeping but after reading my Blog . (ha-ha) !
