7-9 Hours of Sleep for Health, Vitality and Productivity

 

Sleep Benefits

 

Scientists are just beginning to understand the biological purpose and the complex sleep process that affect the functionalities of all the systems of the human body. Our brain functions, immune system, metabolism, respiratory system, blood circulations, and poor mental health, are directly connected with sleep.

Reduced amounts of sleep are also associated with cardiovascular diseases, stroke, a higher infection rate, cancer, depression, Alzheimer’s disease, dementia, schizophrenia, high blood sugar, infertility, obesity, high blood pressure, and lower life expectancies.

“There does not seem to be one major organ within the body, or process within the brain, that isn’t optimally enhanced by sleep (and detrimentally impaired when we don’t get enough). That we receive such a bounty of health benefits each night should not be surprising,” said Matthew Walker a sleep scientist and Professor of Neuroscience and Psychology at the University of California, Berkeley, and founder and Director of the Centre for Human Sleep Science.
