Negative effects on the health of sleep and sleep at night

Negative effects on the brain and the body if the person does not get enough sleep, and in this video the most important effects of the abundance of evening, and not to sleep at night, according to Dr. Matthew Walker, professor of neuroscience and psychology at the University of California Berkeley:

memory loss

Sleeping prevents your brain from storing new memories, because the brain or memory store like the letter box, and without sleep the brain will shut down this store, will not accept any new memories, will be expelled any new information, and you end up losing memory, Be any new memories.

Alzheimer's disease

Lack of sleep increases the formation of a toxic protein in the brain, called amyloid beta, an amino acid, which is formed in the brain and leads to Alzheimer's disease.

If you do not get enough sleep every night, the Alzheimer's protein builds and builds up, and you risk becoming dementia at the end of your life, "Walker said.

Ability to reproduce

Sleep deprivation affects reproduction. A man who sleeps 5 or 6 hours a night has a lower testosterone or male hormone level, to be at a level greater than 10 years. Sleep deprivation accelerates human aging in terms of health and reproductive capacity.


Sleep deprivation affects the immune system. After just one night of sleep for 4 or 5 hours, the number of cancer-resistant cells is 70 percent lower in the immune system, the cancer cells, making the person susceptible to cancer.

heart and blood vessels

Sleep deprivation affects the heart and blood vessels. "In the deep sleep phase of the night we receive the best treatment for blood pressure: the heart rate drops, blood pressure drops, and the heart and vascular rest is recycled before they continue to work," Walker explains. Circulation, and blood pressure continues to rise without rest; therefore, sleep for only 6 hours or less increases the risk of heart attacks and strokes by 200 percent.
