Effects of sleep deprivation shown on the human body

5 Dangers of Sleep Deprivation

It is generally known that the lack of quality sleep can lead to serious health implications. Sleep deprivation has both short and long-term impacts on your health.

In this article we have explained how dangerous insufficient sleep can be.

Risk Of Heart Diseases

People who regularly sleep less than five hours at night often face an increased risk of high blood pressure, the main factor for developing certain heart disease. When you sleep less, your body excretes more stress hormones and other substances that increase the inflammation, which can lead to increased risk of heart disease and stroke.


People who sleep less than five hours a day are two times more likely to develop diabetes when compared to those who sleep between 7 and 8 hours.

The main reason for this is the fact that when sleeping less you can not reach deep sleep -- a condition in which the body rests and regenerates, so your body is experiencing a reduced ability to regulate the blood sugar level.


Insufficient sleep will not only affect your physical state, but you may also feel certain changes in your mental state. Depression is one of the most common side-effects of insufficient sleep. Moreover, the psychological distress caused by decreased sleep creates perfect conditions for the development of various mental disorders

Frequent Diseases And Disorders

While you sleep, your body secreted cytokines, chemicals that help the immune system to fend off infections and diseases. Quality sleep not only affects your body’s ability to deal with infections, but it is directly linked to the antibodies that are generated after the immunization.

Studies have confirmed that chronic sleep deprivation is the main reason why some people have half as much antibodies after the vaccination against flu as those who sleep well.


According to the recent studies, people who regularly sleep less than seven hours a day are 30 percent more likely to suffer from obesity.

Insufficient sleep alters the secretion of hormones that regulate hunger and satiety, which can often lead to overeating. When you are sleepy, it is much easier for you to reach for foods high in fat and calories.
