6 diseases that your lack of sleep may be a cause

Written by

Sleep is not only pleasant but also necessary. While you sleep, your body performs countless functions, including cell growth and repair. It is also responsible for replenishing worn-out muscles and tissues with energy and nutrients (1).

Sleep balances hormones support the immune system, and helps memory function properly. This is why sleep deprivation not only makes you groggy and lethargic, but it also makes you unfocused and forgetful.

Insomnia and illness
Below are 6 cases directly caused by lack of sleep.

Alzheimer’s disease
This is because sleep is necessary to remove waste from tired brain cells and to restore old and damaged structures. If not done properly, it can lead to cognitive decline, dementia, and other brain diseases (2).
In 2013, Johns Hopkins University researchers found that lack of sleep is one of the causes of Alzheimer’s disease.

70 adults aged 53-91 participated in the study. PET scans of participants with poor sleep showed beta-amyloid deposits in their brains.

Because this compound is a hallmark of Alzheimer’s disease, researchers believe that sleep deprivation prevents the brain from removing amyloid-beta debris, making the brain more susceptible to the disease (3).

obesity and diabetes
Researchers at the University of Chicago have found that poor sleep is linked to obesity and, in turn, diabetes (4).

They found that lack of sleep leads to the accumulation of fatty acids that affect metabolism and insulin sensitivity. When researchers analyzed the sleep patterns of 19 men over 3 nights, they found that men who slept just 4 hours a day had 15-30 percent higher levels of fatty acids in their blood than those who slept 8.5 hours a day (5).

People who sleep less often have symptoms of diabetes and obesity, while people who sleep more often do not.

Cardiovascular disease
Cardiovascular disease is largely influenced by diet and lifestyle, so it’s not surprising that sleep plays an important role (6).

At the annual meeting of the European Society of Cardiology, evidence was presented that sleep directly affects the risk of heart disease (7).

A study of 657 Russian men aged 24-64 over the age of 14 found that two-thirds of heart attack victims had sleep disorders.

It has also been found that people with poor sleep have a 2.6 times higher risk of heart attacks and strokes. They increased the risk of stroke by one and a half to four times.


Lack of sleep can cause serious mental problems.

A 2014 study found an association between suicidality and poor sleep, independent of pre-adult depression (8).

A 10-year study from Stanford University School of Medicine followed 420 young and middle-aged adults. Unfortunately, 20 of the participants with poor sleep committed suicide (9).

Chronic sleep deprivation increases the risk of suicide by 1.4 times.

The researchers compared their results with other studies and concluded that poor sleep increases the risk of age-related health problems, particularly among men aged 85 and older.

Ulcerative colitis
Ulcerative colitis is an inflammatory bowel disease characterized by the formation of ulcers along the digestive tract. Studies have shown that colitis, along with Crohn’s disease, is strongly associated with insomnia (10).

In 2014, Massachusetts General Investigators looked at women who had participated in the Nurses’ Health Study (NHS) since 1976 and the NHS II since 1989 and found that women who slept 6 hours or less (regardless of other risk factors) had the most sleep. likely. . age, weight, smoking, and alcohol use) were more likely to have one of these conditions (11).

Ironically, getting more than 9 hours of sleep puts women at risk, which is key to controlling gastrointestinal inflammation.

prostate cancer
A study published in the journal Cancer Epidemiology, Biomarkers, and Prevention found that sleep can protect the prostate (12).

The study involved 2,425 Icelanders aged 67 to 96 and tracked their sleep patterns over 3 to 7 years. Men with poor sleep were 60% more likely to develop prostate cancer than men with poor sleep
