Sleep Mask Benefits

Sleep masks do more than just block out light. Whether you’re jet-lagged, catching up after a night shift, or simply looking to improve your nightly routine, the benefits of a sleep mask can be long-lasting after a good night’s rest.

Light is the most powerful cue for your circadian rhythm. It essentially tells your brain what time it is. Even the tiniest bit of light exposure can suppress melatonin and delay sleep.

“Most research has been conducted in hospitals due to the noise and lights,” says sleep physician Lourdes DelRosso. “Providing sleep masks and earplugs to hospitalized patients has been studied and published, showing that patients experience deeper and more restful sleep. Just by covering their eyes, we can promote better production of melatonin and send better signals to our brain.” Wearing sleep masks at night can also aid cognitive function, including memory, alertness, and episodic learning, according to a study from the Sleep Research Society.

And it’s not just the blackout effect of sleep masks that gives users a well-rested night. Sleep masks are a healthy sleep association, providing a relaxing and comforting experience that can help you wind down at night.

“We have touch receptors everywhere on our skin, including around the eyes,” certified sleep expert Annika Carroll says. “If we apply a little bit of light pressure there with this mask, it releases a hormone called oxytocin, often referred to as the love hormone. It promotes relaxation and comfort.”

If you’re prone to migraines, eye masks can be a simple and powerful ally. Light pressure around the eyes can help ease tension and increase blood flow, while total darkness helps reduce light sensitivity, a common migraine trigger.

Friction breaks down the skin’s elastin and collagen, the proteins that keep your face firm and smooth. Wearing an eye mask while you sleep protects the delicate skin around your eyes from rubbing against bedding or your arm, especially if you tend to toss and turn.

We all know the signs of a rough night of sleep: puffy eyes and dark circles. A sleep mask can help tip the odds by boosting circulation in your face, and weighted eye masks can help break up the excess fluid around the eyes that leads to puffiness.

What Shape and Fit Should I Consider?

Sleep mask fits aren’t universal, Carroll says: “I find that there’s a bit of trial and error in finding a mask that fits your face shape. There are rounder faces, and there are slimmer, longer faces.” Be sure to try on a new sleep mask before giving it a whirl; the mask should press gently against your face without feeling too tight, and there should be no gaps between the mask and your skin, especially around the nose. Additionally, several sleep mask characteristics may affect how well it fits on your face.

Flat sleep masks are the most traditional type you’ll see—a flat piece of fabric that covers the eyes. These types are generally lighter and more compact, making them easy to travel with. Comfort may be a factor here, since flat masks tend to press against the eyes, which some may find bothersome.

A common problem with traditional slip-on sleep masks is the bridge of the nose lifting the mask, allowing light to seep in and defeating the purpose of wearing it. Many sleep masks today are designed with a contoured nose or without fabric around the nose to prevent any light from penetrating.

Some eye masks are built like swim goggles: They feature two convex gaps that allow you to fully open and close your eyes beneath the mask without letting any light in. Eye cups are especially beneficial for people with sensitive eyes and for people who wear eyelash extensions.

Too loose, and the mask will fall off throughout the night. Too tight, and it could uncomfortably press against your eyes or snag your hair while you’re sleeping. Luckily, many sleep masks come with an adjustable strap so you can customize the fit.

When shopping for a sleep mask, examine the product to locate any clasps or adjustable closures. If you’re a back sleeper, you might prefer this piece on the side of your head. Stomach sleepers may find a clasp at the back more comfortable. For those who change positions frequently, consider an unobtrusive adjustment and/or closure mechanism like slim Velcro, a magnetic closure, or a slide buckle.
