Studies at UNiversity College of London, have found and proven that sleep deprived people age faster than those that catch enough Zzzzz’s. This new study has determined that lack of sleep will actually age the brain. Researchers asked study participants on average how much sleep they get each night, then reconnected with those same people and asked them 5 years later how much sleep they got on average. The people whose sleep actually decreased showed signs of age more than those who got enough sleep. The sleep deprived had a mental deficiency decline during cognitive testing that was equal to four to seven years of aging. Sleep regenerates neurons in the brain enabling the brain to function optimally. So how much sleep do people need in general? Six to eight hours is Key to great mental health.
