Alcohol-infused sleep is not continuous, therefore not restorative

Better REM-sleep quality at night provides us with better comprehension of the social world the following day.

Lack of sleep is associated with the increased risk of developing coronary heart disease.

Alzheimer’s disease is associated with the accumulation of a toxic form of protein called beta-amyloid, which forms plaques within the brain. Amyloid plaques are poisonous to neurons, killing surrounding brain cells. The more amyloid deposits, the more impaired the deep NREM-sleep quality is in older individuals.

Getting too little sleep across the adult life span will significantly raise the risk of developing Alzheimer’s disease.
