Sleep is extremely important for the general health of the individual, both mentally and physically. It’s a way to recharge after a long and stressful day. During sleep, millions of processes occur in our body, helping the brain store the important data and memory, and the cells work to repair the damaged tissue and regenerate it.

On the other hand, when we get sleepless, all these functions are not done in time, and we wake up dead and have trouble concentrating the whole day, but more importantly, we are experiencing numerous side effects that can put us in significantly hazards health.

lack of sleep sleep deprivation

Studies show that sleep deprivation can cause serious conditions, and can endanger life, causing heart disease, diabetes and cancer. These are the 6 diseases caused by lack of sleep.

Cardiovascular disease

The link between heart problems and sleeplessness has been suggested several times before, but the strongest evidence for a strong correlation has been found in a recent study presented at EuroHeartCare, the annual meeting of the European Society of Cardiology.

For 14 years, the team of researchers surveyed 657 Russian men aged between 25 and 64 and found that two-thirds of people who had a heart attack also had a sleep disorder.

Moreover, men who complained of sleep problems had a 1/5 to 4 times higher risk of stroke and 2.6 times higher myocardial infarction.

Ulcerative colitis

According to a study in 2014, sleep deprivation and excess sleep can lead to ulcerative colitis, which is an inflammatory bowel disease manifested by ulcers in the digestive tract mucosa, such as Crohn’s disease.

Massachusetts General Hospital’s findings show that adequate sleep is of vital importance to reduce the inflammation of the digestive system, which often causes these diseases.

Obesity and diabetes

Numerous studies and scientists have highlighted the relationship between lack of sleep and diabetes, but a team of researchers at the University of Chicago conducted a study that showed that lack of sleep can lead to obesity, and ultimately to diabetes .

Experts examined the effects of poor sleep on the accumulation of fatty acids because the level of fatty acids in the blood affects the speed and ability of insulin to regulate blood sugar.


Scientists at Johns Hopkins University have conducted a study in 2013 that they found that sleep deprivation can cause Alzheimer’s disease and may also affect the rate of progression.

The study, based on previous research, finds that sleep is of crucial importance to the brain for the removal of “brain waste,” because their accumulation can lead to dementia. A study of 70 adults aged 53 to 91 showed that those who were sleepless had a higher level of beta-amyloid. This compound is a definitive marker of Alzheimer’s disease.

Prostate cancer

The journal Cancer Epidemology, Biomarkers and Prevention, published in 2013 a study that showed that patients with sleep problems were more exposed to prostate cancer.

The researchers tracked 2,425 men in Iceland, aged between 67 and 96 for 3-7 years, and found that the risk of developing prostate cancer was increased by 60% in men with sleep problems.

This number doubled for men who had difficulty falling asleep. Moreover, people with sleep problems were more likely to have an advanced stage of prostate cancer.


In 2014, a study showed that the relationship between increasing suicide incidence in adults and lack of sleep, regardless of previous depression.

Researchers at Stanford University School of Medicine conducted a study that lasted 10 years and involved 420 participants ranging from middle age to late maturity.

There were 20 participants who were suffering from sleep problems, who, unfortunately, committed suicide, which led scientists to the conclusion that those with sleep problems had a 1.4 times greater chance of committing suicide.
