Part 3 in the series: Re-Engineering Human Performance Through Sleep

How well a person sleeps every night can have a huge impact on their health, both mentally and physically. Here are some of the negative health consequences of not getting enough sleep.

Repercussions of Sleep Deprivation
  • Lack of quality sleep (REM sleep) has been linked to an increase in Alzheimer's and Dementia. (1) (2)
  • The protein beta-amayloid has been shown to increase by losing just one night of deep sleep. Beta-amayloid build up in the brain has been associated with impaired brain function and Alzheimer’s disease.(1) (2)
  • The detriments resulting from sleep loss include impaired cognitive and behavioral performance and a dramatic increase in oxidative stress. Oxidative stress is an imbalance of free radicals and antioxidants in the body. While not always harmful, long-term oxidative stress can lead to cell and tissue damage which can contribute to aging and illness.
  • The lack of deep restorative sleep also impacts essential cognitive processing such as memory consolidation and insight formation. (3) (4)
