Your Lack of Sleep Could Be Causing 6 Diseases


Human body can not survive without resting, as it fills the body with energy after long, working hours. While sleeping, certain processes happen in the body and help the brain focus on memory. During these processes, body cells regenerate and tissues repair. In this way sleeping mends all the damage that has happened while you are awake.
If you do not sleep enough you would wake up irritated and moody with lack of concentration. When this happens for a long time, you are likely to experience severe health issues. A particular study involved the effect insomnia has on different parts of the body.
According to study’s findings, lack of sleep triggers serious and destructive ailments, ranging from diabetes to cancer.
  1. Alzheimer’s disease
A 2013 study conducted by researchers at Johns Hopkins University found that a lack of sleep can both be a cause of Alzheimer’s disease and impact the speed of the disease’s progression. The study was conducted based on previous research that discovered sleep is necessary for the brain to get rid of “cerebral waste,” or the garbage-like buildup that can accumulate and cause dementia.
The study involved 70 individuals, aged between 53 and 91. It showed that participants who did not sleep enough had a larger amounts of beta-amyloid in their brain. PET scans were used to determine these results.
This ingredient is considered as a marker of Alzheimer’s. It has helped scientists find that sleep deprivation stops the brain from eliminating its waste.

  1. Obesity and diabetes
Experts have associated poor sleep to diabetes for decades, but recently, researchers at the University of Chicago explained that insufficient sleep leads ti obesity and even diabetes. Fatty acids in blood affect metabolism and the ability of insulin to maintain normal blood sugar. Scientists examined the effect of poor sleep on the accumulation of fatty acid.
They tested the sleeping pattern of 19 men and found that men who slept for 4 hours or less had high fatty acid levels in their blood, which was between 4 and 9 am This was 15-30% higher than the results of men who slept for 8.5 hours every night. This condition may increase insulin resistance and cause pre-diabetes. Men who slept more did not have these obesity and pre-diabetes markers.
  1. Cardiovascular disease

This may be also triggered by sleep deprivation. At the annual meeting of the European Society of Cardiology, a group of scientists presented a study that supported this claim. The study involved 657 Russian men, aged between 25 and 64. The scientists followed their sleeping pattern for 14 years, and found that about two thirds of those men who had survived a heart attack experienced a severe sleep disorder.
What’s more, the men that complained of sleep disorders also were found to have a 2.6 times higher risk of myocardial infraction, a heart attack that occurs when the heart muscle dies, and a 1.5 to four times greater risk of stroke.
  1. Suicide
It may be shocking, but recent research conducted in 2014 found a link between increased incidences of suicide in adults and poor sleep, regardless of past history with depression. During a 10-yearstudy conducted by researchers at the Stanford University of Medicine, 420 participants ranging in middle to late adulthood were examined. Out of this group, 20 participants found to suffer from poor sleep unfortunately committed suicide. Because of this, researchers concluded that those who were experiencing difficulties sleeping on a consistent basis were 1.4 times more likely to commit suicide.
  1. Ulcerative colitis
Ulcerative colitis, an inflammatory bowel disease marked by ulcers within the lining of your digestive tract, as well as Crohn’s Disease can be a product of both sleep deprivation, and excess sleep, says a 2014 study. Researchers from Massachusetts General Hospital found that the right amount of sleep is necessary to curb inflammation responses within the digestive system which often lead to the two diseases.

If you sleep less than 6 hours, you are actually increasing the risk of ulcerative colitis .More than nine hours of sleep increased risks as well, suggesting that the threshold for stopping digestive inflammation is a very narrow window that requires just the right amount of shut-eye. This theory was tested on adult women, and the development of ulcerative colitis was still increased, despite their weight, age, smoking factor, alcohol and others the like.
  1. Prostate cancer
In a 2013 study published within the journal Cancer Epidemology, Biomarkers and Prevention, researchers found an increased incidence and severity of prostate cancer in patients with sleep issues. After following 2,425 Icelandic men between the ages of 67 and 96 for three to seven years, researchers discovered that the danger of developing prostate cancer rose in 60 percent of men who had trouble falling asleep. This number doubled with men who reported having difficulty staying asleep. What’s more, those who experienced sleep problems were also more likely to have later stages of prostate cancer.
Researchers of the study attribute this link to melatonin, a hormone known to regulate sleep. Higher levels of melatonin have been previously founded to suppress tumor growth, while levels of melatonin in those exposed to too much artificial light (a known cause of sleep deprivation) were found to have more aggressive tumor growth.
