Large amounts of alcohol are known to shorten sleep latency, increase slow-wave sleep, and suppress rapid eye movement (REM) during the first half of sleep. During the second half of sleep, REM increases and sleep becomes shallower. A study of the acute effects of alcohol on the relationship between sleep and heart rate variability (HRV) during sleep has found that alcohol interferes with the restorative functions of sleep.
During the process of recovery, many things change within your body. One change is the ability to sleep more easily. While drinking, the alcohol interferes with the type of sleep you are getting, which ultimately affects your overall health down the road. Alcohol rehab facilities here in Denver or any other recovery options know this and strive to improve your sleep while you recover. As we have said before, it is all about the brain chemistry and knowing the root of some problems can lead to a healthy recovery. Read more about how alcohol interferes with sleep below.
Alcohol affects overall sleep architecture," said Yohei Sagawa, a medical doctor in the department of neuropsychiatry at the Akita University School of Medicine. "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 complementary relationship."
