Surprising Effects of Sleep Deprivation (insomnia)
If you do not believe us, let the research that has proven that people who sleep regularly almost never got sick, convince us otherwise. The sleep expert Matthew Walker, author of the book Why We Sleep and a professor at the University of California, reveals that the lack of sleep causes severe damage to our organism.
The negative consequences of those few hours of sleep have a huge negative influence on us:
If you do not sleep enough, your brain will not be able to create new memories, so without sleep, it will be as if the memory box is closed and the brain is incapable of transforming new experiences into memories. New information reaching the brain will not be properly processed and you will have a feeling of amnesia.
Toxins in the brain
The lack of sleep causes an increased level of toxic β-amyloid protein, which is associated with Alzheimer’s disease. During deep sleep, at night the brain eliminates this toxic protein, so when you do not get enough sleep, the brain is not able to do so.
If you do not get enough sleep constantly, your chances of developing Alzheimer’s disease later on in life are increased.

Damage to the reproductive system
The level of testosterone in men who sleep only 5 or 6 hours during the night is drastically lower and it is at the same level present in men who are 10 years older. Hence, the lack of sleep makes you almost a decade older in terms of fertility.
Damage to the immune system
In only a single night with 4 or 5 hours of sleep, the number of cells that fight against cancer reduces by 70%. Your immunity has decreased and your chance of developing cancer during your lifetime is greater.
This list also includes colon cancer, prostate cancer, and breast cancer. In fact, the relationship between lack of sleep and cancer is so strong that recently the World Health Organization declared night shifts for carcinogenic because they impair the sleep cycle.
Damage to the cardiovascular system
During a deep night sleep, you get the most beautiful form of a remedy for blood pressure regulation. The heartbeat reduces and the pressure lowers. 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, your chances of having a heart attack are increased by 200%.
How long can we go without sleep, without experiencing a decline in brain functions and impairments in our physical abilities?
The answer is 16 hours of wakefulness. After crossing this threshold without sleep, we start to feel mental disorientation and worsening of the condition of the whole body. If you are awake for 19 or 20 hours your mental capacity is reduced the same as the capacity of a drunk person sitting behind the wheel.
To prevent damage to your body, try to provide yourself 8 hours of sleep each night.
