Alcohol can act as both a stimulant and depressant, depending on the time and amount consumed. While alcohol can sometimes promote sleep onset, it can negatively impact sleep later in the night resulting in less restful sleep.
Who could benefit from it?
People who have difficulty initiating or maintaining sleep and consume alcohol.
Why this could improve your sleep
Reducing or eliminating alcohol can help reduce the amount of wakefulness experienced during the night and can help with maintaining a normal circadian rhythm. Avoiding alcohol can also help prevent the worsening of snoring or sleep apnea.
