Alcohol does significantly impair sleep quality. Even when you drink regularly and don’t have the typical hangover effects the next day, it still results in many micro awakenings (transitions from deeper stages of sleep to lighter ones) and interferes with the restorative functions (cellular repair, short to long term memory transfer, emotional content processing, etc) that good sleep provides. The tricky part is that your brain has no memory of the micro awakenings so you think everything is fine.

Good for you for recognizing this and making good choices for your health. I’ll still have an occasional cocktail or glass of wine but limiting alcohol intake is one of the simplest and best things one can do to towards better health. 

 Thanks Doc.
