6 Diseases That Can Cause Sleep Deprivation!

The body needs sleep so that it can function properly, if this is not achieved than some serious changes can occur in the body system. You all know how feels just after couple of sleepless nights, you cannot function, concentrate and perform your working tasks. The mood rapidly changes thus becoming grumpy and moody. When you sleep, the body performs numerous processes like helping the brain to keep the important data in the memory, on the other hand the cells are repairing the damaged tissue and regrowth occurs.


Due to lack of sleep the body cannot fulfill its tasks thus causing many illnesses that are severe and a great threat to the whole body. The negative effects of sleep deprivation can lead to deadly conditions like diabetes, cardiovascular disease, and cancer. Shortage of sleep can trigger the following six diseases:


According to the conducted study in 2013 at Johns Hopkins University sleep deprivation can cause Alzheimer’s disease and as well as affect the speed of its progression.

This study resulted from previous research where it was discovered that sleep is very important for the brain so that it can eliminate the “cerebral waste”, or the accumulated buildup that leads to dementia.

It involved 70 adults in range of 53 to 91 years old where it was discovered that sleep deprivation caused higher amount of beta-amyloid deposition in their brains on PET scans.

This substance is actually a definitive marker of Alzheimer’s; showing that lack of sleep prevents the brain from eliminating this kind of “cerebral waste.”


A recent study at EuroHeartCare, the annual meeting of the European Society of Cardiology proved the strong connection between heart issues and sleep disorders.

For a period of time of 14 years, a team of researchers followed the conditions of 657 Russian men in age range of 25 and 64 years old, discovering that two-thirds of the tested individuals who have experienced a heart attack had also sleep disorders.

Likewise, the individuals who suffered from sleep deprivation had 1/5 to 4 times higher stroke risk, and 2.6 times higher threat of myocardial infarction.


Likewise, there is a strong connection between diabetes and lack of sleep which was proven by a conducted study at the University of Chicago lead by team of scientists, it was found out that poor sleep may result in obesity, and eventually, in diabetes.

Team of experts thoroughly examined how bad sleep affects fat accumulation; actually the fat levels in the blood impede the speed and the ability of insulin to control blood sugar.

19 different sleeping patterns were examined, where it was shown that those persons who had 4 hours sleep for three nights had increased fatty acid levels in their blood between 4 a.m. and 9 a.m., which was 15 to 30% increase over those who had 8.5 hours sleep each night.

It was also discovered that the increased fatty acid levels resulted in an increased degree of insulin resistance suggesting occurrence of pre-diabetes.


A released study in 2013 in the journal Cancer Epidemiology, Biomarkers and Prevention, revealed that patients who suffered from sleep deprivation had higher occurrence and severity of prostate cancer. Namely, scientists observed in a period of time of 3 to 7 years, 2,425 Icelandic men in the age of 67 to 96 years old, discovering that the risk of developing prostate cancer was higher at men who had sleep disorders, specifically in 60% of the observed men. Furthermore, the men with sleep disorders were more prone to later stages of prostate cancer.

This was actually linked to the hormone melanin which is a sleep-regulating hormone. Namely, people with higher melatonin levels were found to reduce tumor development, contrary to melatonin levels in people exposed to excessive amount of artificial light, which is related to sleep deprivation, had more aggressive tumor development.


Suicide is also linked to poor sleep no matter of the previous depression history. A team of scientists at the Stanford University of Medicine have conducted a study lasting for a whole decade and involved 420 persons in their middle and later ages.

Unfortunately, 20 persons who suffered from poor sleep committed suicide, which lead to conclusion that persons who regularly struggled with sleep issues were 1.4 times most likely to commit suicide.

Most vulnerable to this effect of sleep shortage were white males, in the age of 85 years old and older, the increased suicide rate was linked to poor sleep, health problems, and increased stress with age.


Both sleep deprivation and excess sleep may lead to ulcerative colitis, revealed a study conducted in 2014. Ulcerative colitis is an inflammatory bowel disease manifested by ulcers within the lining of the digestive system, along with Crohn’s Disease.

Experts from Massachusetts General Hospital reveal that sleeping properly is very important for restraining inflammation reactions within the digestive system.

Another study involved women in the Nurses’ Health Study (NHS) I since 1976 and NHS II since 1989, where it was shown that the threat of ulcerative colitis was increased due to reduced sleep of 6 hours or less.

However, 9 hours sleep can also increase the threat of this disease, therefore proper amount of sleep is a must if you want to avoid these diseases.

Even so, the studies were performed solely on adult women; the increased risk of developing ulcerative colitis very much depended on age, weight, drinking consumption and smoking cigarettes.
