Lack of Sleep Causes These Diseases


Sleep is very important for your overall health.

A good night’s sleep is preparing your body for the next day. If your brain is well rested, you will be able to focus, learn, and remember things easily. The sleep process is devoted to repairing and regenerating the body as the body undergoes detoxification.

First of all, sleep deprivation causes serious anxiety, affecting your mood and energy.

Prolonged sleep deprivation can lead to serious health problems. According to several studies, poor sleep is linked to the following diseases.

Alzheimer’s disease

A study conducted at the Johns Hopkins Univerisity showed that sleep deprivation leads to cognitive decline and onset of Alzheimer’s disease. Additionally, the lack of sleep accelerates the progression of this neurodegenerative disease. Your brain needs 7 to 8 hours of sleep in order to maintain it healthy. The study involved 70 participants at the age between 53 and 91 years old. The participants who lacked sleep had plaques of beta-amyloid building in their brain, which is a marker of Alzheimer’s.

Obesity and diabetes 

Researchers at the University of Chicago stated that sleep deprivation increases the risk of obesity and diabetes. They conducted a study which involved 20 men. The lack of sleep affects your metabolism and your blood sugar levels and this study proved that. The tests showed that men who slept less than 5 hours had 30% higher fatty acids in their blood compared to men who slept for 8 hours every night. These type of results may lead to pre-diabetes condition.

Cardiovascular disease 

In order to investigate the effects of sleep deprivation on the heart health, there was a study which involved 657 Russian men, at the age of 25 and 64. Their sleep-and-wake cycle was followed for 14 years. The group with men who lacked sleep were twice as likely to experience myocardial infarction.


Shockingly enough, a study has shown that poor sleep increases the risk of suicide in people who are diagnosed with depression. The study was led for 10 years and it was concluded that 20 participants of 420 who struggled with insomnia, ended up committing suicide.

Ulcerative colitis 

Proper sleep is very important for your digestive health. The lack of sleep can cause serious gastrointestinal problems and increase the risk of ulcerative colitis. Increased sleep duration also contributes to developing ulcerative colitis.

Prostate cancer 

According to a study which was published in the journal Cancer Epidemiology, Biomarkers, and Prevention, people who experience sleep disorders are more likely to develop prostate cancer. This study involved 2,500 men from Iceland at the age between 67 and 96. Men who were struggling to fall asleep were also 60% more likely to develop prostate cancer.
