Here are three things experts say you shouldn't do if you want to get a good night's sleep in this miserable weather.

Nighttime skincare in a brightly lit bathroom

Breus says that in the summer, we're exposed to more sunlight during the day, so exposure to more light in the evening can lead to later bedtimes and less sleep.

Light inhibits the production of melatonin, which is considered the "key to turning on the sleep engine." Melatonin is a hormone produced by the body and is released when it gets dark.

Experts recommend limiting exposure to things like electric lights or screens in the evening.

"A lot of people remove their makeup or do their skincare routine right before bed in a brightly lit bathroom," says Breus. "Depending on how bright the bathroom or mirror lights are and how long your skincare routine is, this can really impact your sleep."

Super bright environments tell your brain it's morning, which stops it from producing melatonin. You don't need to moisturize in the dark, but you should moisturize earlier, like right after dinner or around 6-7pm.

In addition to avoiding indoor light right before bed, Breus recommends closing the curtains and using an eye mask.

Exercise 2-3 hours before bed

Our body temperature varies a lot, but it tends to be higher towards the end of the day. According to Breus, our body temperature will rise until around 10:30pm, then drop. When it drops, it signals the brain to release melatonin.

Exercise raises our body temperature, and it can continue to rise for hours after we finish our workout.

Exercising close to bedtime raises your body temperature, making it harder to fall asleep

“If you’re too hot, melatonin won’t be released, which can interfere with your sleep,” he explains. “So avoid exercising too close to bedtime, maybe two to three hours before bed.”

Drinking alcohol right before bed

Summer is often a time when we stay up later and stay out longer. People’s social lives are more active in the summer, which leads to more alcohol consumption, later meals, and a little later socializing.

Plus, summer is a popular time for vacations. While it’s great to enjoy yourself and have fun, Breus reminds people that some summer habits can disrupt a good night’s sleep.

One of those habits is drinking alcohol late at night. Alcohol affects gamma-aminobutyric acid, or GABA, a neurotransmitter that inhibits impulses between nerve cells and has a calming effect, The New York Times reports.

Alcohol can also suppress REM sleep cycles. At the end of the night, when the alcohol levels drop, your brain becomes overactive and you toss and turn.
