What happens to your body and brain if you do not sleep enough?

Lack of sleep makes you de-concentrated and irritable and adversely affects your brain, cardiovascular, reproductive and immune system.


Are you sometimes in a race with time – you are dedicated to the workplace, but want to see with your partner, so with friends, so you can prepare some healthy meal, then finish some domestic duties, so read a book and go to fitness and in the end you’re exhausted and completely unobstructed?

Sleepwalker Matthew Walker , author of the book “Why We Sleep” and a professor at the University of California, found that lack of sleep causes us great harm.


The negative consequences of the few hours of sleep have a huge negative impact on us:

Weak memory

If you do not sleep enough your brain will not be able to create new memories, so without a dream it will be as if the memory box is closed and the brain is incapable of turning new experiences into memories.

The new information that is touching will not be properly processed and you will feel like you have amnesia.

Toxins in the brain

Sleep disorder causes an elevated level of toxic protein beta-amyloid, which is associated with Alzheimer’s disease. During a deep sleep at night, the brain is released from this toxic protein, so when you are not sleeping enough, he will not be able to do so.


If you do not sleep well enough, you have a greater chance of developing Alzheimer’s disease in the later stages of life.


To the detriment of the reproductive system

Testosterone levels in men who sleep only 5, 6 hours at night are dramatically lower and are at the level of a 10-year-old man older than them.

So that sleep deprivation ages for almost a decade in terms of fertility.

Damage to the immune system

After just one night with 4, 5 hours of sleep, there is a 70% reduction in cancer cells. Your immunity has fallen and the chance of cancer during your lifetime is greater. On this list is colon cancer, prostate cancer and breast cancer.

In fact, the association of sleep and cancer is so strong that the World Health Organization has recently declared night shifts for carcinogens because they are ruining the rhythm of sleep.


To the pity of the cardiovascular system

During deep sleep, you get the best form of medicine to regulate blood pressure. Scarring decreases and pressure diminishes.

If you do not sleep enough, your cardiovascular system does not relax in this way and you will have high blood pressure. With less than 6 hours of sleep you have 200% more chances of a heart attack.

How much time can we endure without sleep without experiencing a decline in brain functions and disorders of our physical abilities?

The answer is 16 hours of alertness. After crossing this threshold without sleep, we begin to have mental disorientation and worsening of the state of the whole body.

If you are awake 19, 20 hours your mental capacity is reduced as a very drunk person sitting behind the wheel.


In order not to do harm to your body, try to secure yourself 8 hours of sleep each night.
