If your child's bedroom looks like broad daylight at 8 p.m. this summer, blackout curtains might be one of the simplest sleep tools you're overlooking.
During the summer and early fall, longer daylight hours can make bedtime tough, especially for younger kids whose bedtime arrives well before sunset.
That's because our sleep-wake cycles are strongly influenced by light and darkness. Darkness helps create an environment that supports our body's natural sleep signals, including melatonin. The American Academy of Pediatrics recommends a dark sleeping environment as one way to support healthy sleep.
So yes: blackout curtains can absolutely be helpful, especially if your child's room gets a lot of evening light, early-morning sunshine, or bright outdoor lighting. AAP guidance even specifically suggests heavy or blackout curtains when light is bothering a teen's sleep.
But blackout curtains aren't magic.
The bigger picture still matters: a consistent bedtime and wake time, a calming bedtime routine, a comfortable room temperature, and getting screens out of the bedroom are all important pieces of healthy sleep.
And don't make the entire day dark. Morning and daytime exposure to natural light helps reinforce your child's circadian rhythm too.
So if later sunsets are wrecking bedtime? Blackout curtains are a reasonable, and pretty simple, thing to try.
