Not getting the best sleep due to more daylight in the summer? Blackout curtains could be a simple solution.

According to Dr. Daniel Barone, a neurologist at Weill Cornell Medicine and New York-Presbyterian, one of the easiest things you can do to get better shut-eye at night is to make sure the room is dark.

“We’re designed to be sleeping when the sky is dark,” he told TODAY. Things like street light can disrupt the sleep cycle. “You want the room to be as dark as possible without it being dangerous,” he added.

To achieve a perfectly dark room, he recommended blackout curtains. These are curtains that block out light to help you sleep through the night. Many also have the advantage of blocking outside noise and regulating the temperature in the room by keeping hot and cold air from coming in through the window.

Below, see some of the best-selling blackout curtains on Amazon.

If you do end up blocking the light in your room with blackout curtains, Barone has one important tip: open the curtains immediately when you wake up and let the light in. “When we’re awake, we want to be exposed to sunlight,” he said. “Try to get sunlight in the morning.”
