Sleep is the essential rest of the body which supports all bodily functions. During the night, the body sleeps and thus recharges after the stressful and hard day.
During this time, millions other processes occur in the body, helping the brain to memorize things, and the cells to regenerate and repair the damaged tissues.
Therefore, the lack of sleep impedes all these processes, and prolonged sleep deprivation might seriously endanger health.
Apparently, researchers have studied the exact consequences of the chronic lack of sleep on the body, and they found that they include the development of serious and life-threatening conditions, ranging from cancers to diabetes, and heart issues.
Poor sleeping habits lead to the following six diseases:
1.Obesity and Diabetes
Poor sleep has been related to diabetes for long, but scientists at the University of Chicago recently found the way how poor sleep can potentially cause obesity and diabetes.
They analyzed the effects of little sleep on fatty acid buildup, as the levels of these acids in the blood affect the speed of metabolism and the insulin’s ability to regulate blood sugar.
They examined 19 men with different sleeping patterns and found that those who slept for 4 hours over the span of three nights had high levels of fatty acid within their blood between 4 a.m. and 9 a.m., which was 15-30% higher than those who slept for 8.5 hours each night.
Additionally, they found that the increase in fatty acid levels also increased insulin resistance, leading to pre-diabetes.
According to the findings of a 2013 study conducted by researchers at Johns Hopkins University, a lack of sleep can both, lead to Alzheimer’s disease, and accelerate its progression.
The study was based on previous research that found that sleep is necessary for the brain to eliminate “cerebral waste,” or the garbage-like deposits that can accumulate and lead to dementia.
The study involved 70 adults between the ages of 53 and 91, and showed that participants who reported getting poor sleep each night had a greater amount of beta-amyloid deposition in their brains on PET scans, a compound which is a definitive marker of Alzheimer’s disease.
3. Cardiovascular Disease
Poor sleep has been related to cardiovascular diseases, and a recent study presented at EuroHeartCare, the annual meeting of the European Society of Cardiology, confirmed this link.
The study involved 657 Russian men between the ages of 25 and 64 for 14 years, and nearly two-thirds of those who experienced a heart attack also had a sleep disorder.
The men who complained of sleep disorders had 2.6 times higher risk of myocardial infraction, which is a heart attack that occurs when the heart muscle dies, and 1.5-4 times higher risk of stroke.
