6 Diseases Your Lack of Sleep Could Be Causing

As many of you already know, sleep is pivotal for our health and well-being and it helps us recharge after a long and stressful day. What you may not have known by now is that when we sleep, there are millions of processes going on in the body like repair of damaged tissues and storing of important information in the memory.

What Happens When We Do Not Get Enough Sleep?

Lack of sleep can impede the above-mentioned crucial processes and we will be more tired in the morning and have problems with our concentration and focus. When this goes on for a longer period of time, we can experience a serious decline in our overall health.

Diseases Caused by Sleep Deprivation

Heart illness

According to a 14-year study presented at EuroHeartCare, 2/3 of the participants who experienced a heart attack had a sleep disorder and the men who suffered from a sleep disorder had a 1/5 to 4 times higher chance of stroke and 2.6 times higher risk of myocardial infarction.

Ulcerative colitis

Sufficient hours of sleep are pivotal for the prevention of inflammation responses within the digestive system, which is frequently the cause of ulcerative colitis, a type of inflammatory bowel disease characterized by ulcers formed on the lining of digestive tract.

Diabetes and obesity

A study conducted by researchers from the University of Chicago points out that insufficient sleep can easily cause obesity and ultimately diabetes. It was found that then men who slept for 4 hours for 3 nights in a row had higher levels of fatty acid in the blood between 4 am and 9 am. Another thing they revealed is that these high fatty acid levels elevated the insulin resistance, which is an indicator of pre-diabetes.


A study led by scientists from Johns Hopkins University from 2013 showed that sleep deprivation can trigger Alzheimer’s and speed up its progress. In 70 adult participants between the ages of 53 and 91, the lack of sleep elevated their beta-amyloid deposits in the brains and this was revealed on PET scans. This compound is known to trigger Alzheimer’s. Insufficient sleep averts the brain from expelling this ‘cerebral waste’.

Prostate cancer

A study done in 2013 and published in the journal Cancer Epidemiology, Biomarkers, and Prevention demonstrated a higher risk of prostate cancer in patients suffering from some sleep-related issue.


Done in 2014, a study found a close link between the incidence of suicide in adults and poor sleep. The study lasted for 10 years and included 420 participants from middle to late adulthood. 20 of those who had sleeping problems committed suicide and the risk in them was 1.4 times higher.
