Let's Hope These Don't Make You Lose Sleep Some More.
We simply could not overemphasize the importance of sleeping. Especially now that scientists link lack of sleep to Alzheimer's, obesity, heart ailments, and even death, among others.
Check out 5 of the dangers associated with chronic lack of sleep:
1. Alzheimer's Disease - that dreaded ailment anyone approaching the age of 65 starts worrying about. Why, it afflicts 34 million worldwide (Alzheimer's Disease International), and this number could increase by more than 35 million by 2010. To make things worse (and scarier) is that there is still no known cure for this disease. Alzheimer's Disease is the most common form of dementia. Those afflicted with it suffer memory loss and confusion. This will worsen to a point the patient will not be able to care for himself, and not know what to do when the urge to go to the bathroom arises.
In a study published by Reuters, scientists discovered that chronic lack of sleep spurs the development of toxic plaques in the brain that destroys neurons.
2. Alters hormones and metabolism - having just four hours of sleep each night can make you look old - after less than a week. Sleeping less than the standard eight-hour sleep produces a significant change in your glucose tolerance and endocrine function. These changes resemble the effects of aging or diabetes in it early stages.
3. Weight gain - the most obvious tie-ins to obesity would be sleep-deprivation and the wooziness that makes exercise a near impossibility. But it's more than that. As cited above, some of the changes include hormonal imbalances involving leptin and ghrelin. Leptin suppresses your appetite so you'll stop eating, and makes you more active so you burn off more energy. Ghrelin, on the other hand, stimulates hunger. You have more ghrelin before meals and it decreases after meals.
When you are sleeping, leptin increases so you don't feel hungry. When you lack sleep, leptin is at a low supply and you have too much ghrelin that tells your brain you are hungry. So you eat. And eat. And eat.
3. Increased susceptibility to common cold - in a study published in Archives of Internal Medicine, 153 healthy participants' sleep efficiency were monitored for 14 days. They were then quarantined and administered nasal drops containing rhinovirus, a type of virus that is responsible for common colds in adults and children. Those who had slept less than 7 hours on average were found to be more likely to develop colds compared to those who sleep at an average of 8 hours or more.
4. Heart problems - Time.com reports a study published in the Journal of American Medical Association, that "too little sleep can promote calcium buildup in the heart arteries, leading to the plaques that can then break apart and cause heart attacks and strokes."
5. Diabetes - chronic lack of sleep causes hormonal imbalance (there it is again!) that affects glucose regulation. You don't produce enough insulin producing cells that, in turn, cause your glucose levels to rise. Insulin is necessary to keep your blood sugar level in check. If you don't sleep enough (7-8 hours a night) for a whole week, insulin and blood sugar levels in your system mimic those of a diabetic's.
We've just named 5, and there are a lot more. As it weakens your immune system, one possible effect of chronic lack of sleep is death. Continually depriving yourself of enough sleep could lead to long-term changes in the brain or mental disorders such as depression. Sleep is the time when our brain consolidates memory and information, it is needed to regenerate certain parts of the body.
If you think you are being productive when you skip sleep to work, think again. Don't go to bed thinking about this tonight as this could be worrisome. Worry causes stress.
Stress can keep you up at night, sleepless.
