Lack of sleep and unpredictable dangers to the body

Lack of sleep can cause negative effects for almost every organ in particular.

Central nervous system

Lack of sleep can make the brain exhausted and unable to perform its tasks well. Therefore, when you lack sleep, you will find your body sluggish, sleepy and yawn a lot. This can affect your ability to concentrate, remember, absorb new things, even decision-making and creativity.

nerve system

The central nervous system acts as a communication channel, helping to control the behavior of the body. A good and sufficient sleep is essential to ensure these activities take place normally.

Immune system

During sleep, the immune system produces infection-fighting substances such as antibodies and cytokines. These substances will work to protect the body from environmental pathogens such as bacteria and viruses.

Not getting enough sleep makes the immune system unable to function at its best. Some studies show that if you don’t get enough sleep, your body won’t be able to fight off environmental threats. In addition, it will also make the body take a long time to recover from illness. More dangerous, long-term sleep deprivation also increases the risk of chronic diseases such as diabetes and heart disease.

Respiratory system

Lack of sleep can increase the risk of respiratory infections such as the common cold and flu. Also, if you already have lung conditions, such as chronic pneumonia, a lack of sleep can make these conditions worse.


According to a Harvard Medical School study, sleep deprivation and weight gain are linked. Sleep deprivation reduces production of leptin, a hormone that helps the brain recognize when you’ve had enough, and increases production of ghrelin, a hormone that stimulates appetite.

A lack of sleep can also make you feel too tired to exercise. Over time, the effectiveness of this physical activity will decrease and cause your body to gain weight because it is not burning enough calories.

Lack of sleep increases diabetes risk

In addition, not getting enough sleep also causes the body to produce higher insulin levels after eating, promotes fat storage and increases the risk of type 2 diabetes.

Cardiovascular system

Sleep plays an important role in helping the body heal and repair damage related to blood vessels and the heart. Not getting enough sleep increases the risk of chronic diseases such as high blood pressure and stroke. According to the results of one study, lack of sleep can cause people to have high blood pressure the next day.

Treatment of sleep deprivation

The most basic form of sleep deprivation treatment is getting enough sleep, usually 7-8 hours per night. This is often easier said than done. You may need the help of a doctor or sleep specialist to diagnose and treat a sleep disorder.
