Sleeping like Sleeping Beauty
Alcohol not only affects your sleep (falling asleep quickly, but less deep sleep) but also snoring. The numbing effect of alcohol causes the muscles that keep your pharynx open to relax. The air passing through your nasal and oral cavity creates vibrations and they make sound. Add to that the fact that alcohol has a negative effect on your breathing control. A 'cocktail' that is bound to lead to snoring. Because alcohol also ensures that you wake up less quickly, you do not hear your own snoring, while the sound can be compared to that of speeding traffic.
Every day without alcohol has a positive influence on snoring (unless there is another cause for snoring, such as a cold or an allergy).
A longer time without alcohol ensures that you sleep better.
Win win.
