Although experts can’t be certain that alcohol directly causes insomnia, numerous studies have found a link between this sleep disorder and alcohol consumption. Consuming alcohol causes physiological changes that affect snorers and people with https://thebostondigest.com/top-5-advantages-of-staying-in-a-sober-living-house/ obstructive sleep apnea (OSA), which occurs when tissues in the nose or throat collapse and temporarily obstruct the airway. It also causes changes to blood vessels in the nose, leading to greater airway resistance in the nasal passages.
Alcohol interrupts your circadian rhythms
As a result it may precipitate — or increase the frequency of — parasomnias which occur during this stage of sleep. Using alcohol to help you relax and sleep may actually be masking a sleep disorder that needs treatment. Just as alcohol affects all of us in different ways — and at different stages — there’s no set rule for how it will affect your sleep.
Tips for Sleeping Better if You Plan to Have a Drink or Two
Studies show a direct link between alcohol consumption and OSA, since drinking alcohol causes throat muscles to relax. For a person who already has sleep apnea, drinking alcohol can exacerbate the problem, making for an even worse night’s sleep. If you don’t have an existing case of OSA, drinking even a small amount before bed can cause this issue. Research also indicates that drinking alcohol makes a person more likely to experience a sleep-related eating disorder. The primary characteristic of these disorders is episodes of binge eating during the night.

Alcohol also relaxes throat muscles, and this relaxation can worsen sleep-related breathing problems and contribute to sleep apnea. What’s more, alcohol may increase the need to urinate during the night — just another way in which it can disrupt sleep.
Sleep Health & Hygiene
Alcohol also increases breathing-related sleep events such as snoring and oxygen desaturation, especially in those with pre-existing problems. Emerging data demonstrate that insomnia may co-exist with SSD and circadian abnormalities. Future studies should unravel these tentative associations in individuals who misuse alcohol.
Research also suggests alcohol impairs a person’s response to light cues, which is a crucial part of regulating your internal clock. According to Avidan, you should stop drinking at least four hours before you go to bed to reduce your risk of disrupted sleep. “It is best to drink early enough in the evening so that the alcohol is metabolized before going to sleep,” adds Benjamin.
