Leading neurologist Matthew Walker said that lack of sleep increases the risk of cancer, heart attack and Alzheimer's, disease.
According to the scientist, if people knew about the links between sleep loss, Alzheimer's disease, cancer, diabetes, obesity and mental health problems, they would try to get the recommended eight hours of sleep.
More than 20 large-scale epidemiological studies indicate a clear relationship: the shorter your sleep, the shorter the life. For example, adults aged 45 and over who sleep less than six hours a day have a 200% chance of earning a heart attack or stroke over a lifetime, compared to those who sleep seven or eight hours a day.
It should be noted that sleep has a powerful effect on the immune system. The lack of sleep even for one night dramatically reduces the resistance of the body.
A short sleep can affect even anti-cancer immune cells. Disorders in circadian rhythms of sleep lead to an increase in the likelihood of cancer, including prostate, endometrial and colon cancer.
Too little sleep in an adult's life significantly increases the risk of developing Alzheimer's disease. The reasons for this are difficult to generalize, but this is due to the deposition of protein toxin, which accumulate in the brain of people suffering from this disease, killing surrounding cells. During deep sleep, such deposits effectively cleanse the brain.
In addition, deep sleep is a part when we begin to dream - this is a therapeutic state during which we are freed from negative emotions.
So have a sound sleep everyday and live healthier and happier!
