Alcohol Affects Sleep
New research finds that large amounts of alcohol affects sleep. The study has illustrated that drinking alcohol interferes with the restorative functions of sleep. “Normally, during physiologic nocturnal sleep in humans, the parasympathetic nervous system, responsible for ‘rest-and-digest’ activities, is dominant over the sympathetic nervous system, responsible for stimulating activities. We wanted to investigate how alcohol may change this complimentary relationship,” said Dr. Yohei Sagawa, a neuropsychiatrist at the Akita University School of Medicine in Japan. “Many alcoholics and habitual drinkers suffer from insomnia,” said Sagawa. Alcohol impedes people getting to sleep, deep sleep, trouble staying asleep and a hard time getting up in the morning.
