Several decades ago, on average, people have slept for 8 hours per night. Today, this number has dropped to 6.8 hours. But, did you know that health experts recommend a good quality sleep of 7-9 hours per night?

Here we show you the consequences to the human health due to sleep deprivation.

Sleep Deprivation Can Make You Sick

Lack of sleep is the most common cause of nervousness, headaches and migraines. But, be careful not to overdo it, as too much sleep can also trigger headaches and migraines.

Cognitive Impairment

Being sleep deprived hampers the person’s ability to think clearly and to learn new things, which can often be seen among adolescents.

Memory Problems

Just as it affects the ability to learn things, sleep deprivation can make it difficult for you to consolidate your memory and remember things that have happened in the past.

Concentration Problems

Lack of sleep can make it difficult for you to keep your attention and stay concentrated. You have probably noticed that it’s more difficult to read a book or pay attention to a presentation at work while being sleep deprived.

Weight Gain

Sleep deprivation is associated with increased appetite, a desire for high-calorie food as well as less control of the hunger impulse. When all three are combined, they give a very dangerous combination, right? While it’s true that our organism burns calories faster when we’re awake, this is not the case when we’re exhausted.

Heart Disease

Studies have shown that lack of sleep elevates the blood pressure levels and increases the risk of heart disease.

Respiratory Infections

Sleep deprivation makes the affected person more susceptible to respiratory infections, such as common colds and flu. It can also worsen an already existing disease of the respiratory system, like chronic lung disease.


When you have an open wound, your immune system protects you from instant infection. However, being sleep deprived puts you in danger, as it hampers this ability of the organism.

Reduced Libido

Sleep deprivation affects the levels of testosterone in both, men and women, and thereby reduces their sexual drive.


Being awake in moments when your body feels the need for sleep destroys your metabolism. This in turn puts you at risk of developing diabetes.


Spending too many sleepless nights can influence the person’s mood, and trigger anxiety and depression.

Risk Of Premature Death

Studies have shown that sleep deprivation lowers the quality of life and increases the risk of premature death by up to 12 percent.
