What Are Blackout Curtains?

Next time someone is redecorating their bedroom, they should think about whether blackout curtains could be helpful.

As we all know, a dark room is of utmost importance when people are trying to get some rest. Darkness causes one’s body to release melatonin, which is a hormone that causes people to feel sleepy.

The National Sleep Foundation explains: “Exposure to light stimulates a nerve pathway from the retina in the eye to an area of the brain called the hypothalamus. There, a special center called the suprachiasmatic nucleus (SCN) initiates signals to other parts of the brain that control hormones, body temperature and other functions that play a role in making us feel sleepy or wide awake.”

Translation: Darkness is important because it tells the body it’s time to go to sleep.


Blackout curtains are one way to make a bedroom as dark as possible. These are specifically designed to stop light from filtering through and come in the form of blackout curtains, blackout linings, or blackout blinds. Blackout curtains can also help muffle sounds from outdoors, particularly if people live on a busy street.

So, who might benefit from blackout curtains? While eye masks are an easy, portable way to make a sleeping environment seem as dark as possible — but they don’t work for everyone. If people toss and turn in their sleep, an eye mask may come loose in the night. And some people simply don’t like the feeling of fabric over their eyes or elastic straps against their head. For those people, blackout curtains may be helpful.

Blackout curtains are also useful in children’s bedrooms, especially for young children who may go to sleep before sunset. And if you are a night shift worker who sleeps during the day, blackout curtains may help you stay on your ideal rest schedule.
