This article explores how alcohol affects your quality of sleep. It also covers what symptoms you might have if you don’t wait long enough between having your last drink and going to bed.
How Alcohol Affects Sleep
Alcohol may be consumed in beer, wine, and hard liquors like vodka, rum, gin, and whiskey. It is more often consumed at night, also called a nightcap, and may negatively affect your sleep. While alcohol can make you feel tired at first, it can also disturb your sleep as it wears off.
When it comes to sleep, alcohol:
Enhances the brain’s levels of a chemical called adenosine, which can lead to sleepiness Relaxes the airway and can worsen snoring, as well as pauses in breathing known as obstructive sleep apnea Wears off quickly, which can lead to frequent, short awakenings Can interrupt rapid eye movement (REM) sleep, which is important for dreaming, learning, and memory processing
Wait Between Drinking and Bedtime
It is recommended that alcohol not be consumed in the last four hours before bedtime. Even though alcohol may help you fall asleep, it interferes with the quality of your sleep.
Moreover, it can take one hour for your body to process one serving of alcohol. If you’ve had several drinks, it’s best if your last drink is finished at least several hours before you go to bed.
What Happens When You Drink Alcohol Right Before Bed?
If you drink alcohol right before bed, you may experience:
Frequent awakenings Night sweats Nightmares Headaches
If you binge drink, or drink large amounts very quickly, you can alter your melatonin levels for up to a week afterward. Melatonin is a hormone that your body makes to help regulate sleep.
Summary
Whether you have had one or multiple drinks, it’s best to wait for your body to fully process the alcohol before heading to bed. In general, try to avoid drinking alcohol four hours before you plan on going to sleep.
It’s important to treat sleep disorders such as insomnia (difficulty falling or staying asleep) or sleep apnea (when breathing stops multiple time a night) if they are present.
Even though alcohol can make you feel sleepy, it may impact your overall quality of sleep. If you go to bed with alcohol still in your system, you may experience headaches, frequent awakenings, night sweats, more intense snoring, and nightmares.
If alcohol continues to disrupt your overall sleep quality, you may consider cutting it out entirely, or limiting your intake before bedtime. If you’ve stopped drinking alcohol, but are still having sleep issues, be sure to reach out to a sleep specialist.
