Lack of sleep may have numerous side effects on the overall health, because it increases the risk of experiencing different health issues. Therefore, if you sleep 7 hours or less a night, you are more likely to suffer from these health conditions:

1. High levels of blood sugar

Participants in a recent study have been asked to sleep for 4 hours per night. The 6-day study has shown that they had reduced sugar (glucose) tolerance by 40 %, which increased the risk of experiencing diabetes.

Namely, when the human body is at rest, it lowers the production of hormones, such as: cortisol. Therefore, the levels of cortisol remain increased if the individual is deprived of sleep. This increases the glucose levels.

In addition, high levels of blood sugar lead to nerve damage, poor vision and kidney disease.

2. Alzheimer’s disease

Lack of sleep can lead to or increase the risk of Alzheimer’s disease. In a 2013-research, the scientists have found out that the adults, who lacked sleep, had higher amounts of ‘brain waste’ than usual. Moreover, this brain waste contributes to other health issues.

3. Cardiovascular disease

According to the researches, 45-year old adults, who sleep less than 7 hours per night, are more likely to experience stroke or heart attack. Lack of sleep keeps the high levels of blood sugar, which increases the risk of experiencing heart diseases.

According to Dr. Diane Lauderdale, blood sugar levels decrease at night for many people.

4. Viral infections

When we are sleeping, the immune system creates T-cells that fight viruses in the body. According to Dr. Diwakar Balachandran, if people are sleep deficient, the production of T-cells is reduced. Sleep deprivation can increase the risk of experiencing a common cold or flu. In addition, sleep deprivation leads to stress, which in turn weakens immunity.

5. Prostate cancer

Lack of sleep reduces the levels of melatonin in the body. Melatonin is necessary for the prevention of tumor growth.

A 2013-study found out that the reduced levels of melatonin in the body increase the risk of prostate cancer. Namely, people, who are deprived of sleep, have increased risk of prostate cancer.

6. Suicide

Numerous studies have shown that lack of sleep significantly increases the risk of suicide, even though the person does not experience depression.

In addition, the poor sleep quality may lead to suicide.

7. Ulcerative colitis

According to researches, lack of sleep hinders the ability of the human body to fight inflammation and prevent ulcerative colitis.

The digestive inflammation is manifested with ulcers and long-term inflammation in the digestive tract. Moreover, it increases the risk of experiencing other health issues, including toxic megacolon and liver disease.
