Best Sleep Masks

A sleep mask refers to any barrier that is placed over the eyes to block out light during sleep. Typically, they are made of a soft, lightweight material that wraps around the head.

Human sleep cycles correspond to the presence or absence of natural light, causing us to feel alert during the day and more tired at night. While many people use sleep masks at night, they can also create artificial darkness that allows sleepers to feel more relaxed and ready for sleep while the sun is out.

Sleep masks can be useful for shift workers and other people who normally sleep during the day. They can also help people fall asleep on planes and other forms of public transportation, and can ease jet lag symptoms.

Most sleep masks sold today are made from fabrics such as cotton, polyester, nylon, or silk. Some models also have foam padding that offers comfortable cushioning and blocks out more light.

Our picks for the best sleep masks include a variety of models with varied materials and price-points. We’ll also cover what to look for in a sleep mask and other factors that can contribute to quality sleep.

How Do Sleep Masks Work?

Sleep masks are completely opaque and are designed to fit snugly over both eyes. They are typically made from one or more of the following materials:

• Natural fibers: Fabrics such as cotton and silk are light, breathable, and hypoallergenic. One notable downside of sleep masks made of natural fibers is that they tend to degrade quickly after repeated washes.
• Synthetic fibers: Synthetic fabrics such as polyester are not as breathable as natural fibers, but they are usually just as soft and lightweight. Like sleep masks made of cotton and silk, those made of polyester typically wear out over time.
• Foam materials: Foam sleep masks are designed to conform to the wearer’s face. Sleep masks made with polyfoam or memory foam often come with recessed cavities that prevent the eyes from coming in direct contact with the mask to help reduce irritation and discomfort.

Sleep masks are usually made with elastic bands that fit over the head for added comfort, and some feature side vents to improve air circulation. Sleep masks are typically designed to be worn with earplugs, and some models come with a pair of earplugs.

The primary function of a sleep mask is to block light during sleep. By creating a darkened sleep environment, masks can aid with sleep in the following ways:

Improved melatonin levels: Melatonin is a natural hormone that helps control circadian rhythm and the sleep-wake cycle. Melatonin is produced during periods of darkness and creates feelings of drowsiness that make it easier to fall asleep and stay asleep.

Sleep masks can effectively regulate melatonin production for people who sleep during periods of daylight. This includes individuals who work at night, as well as people trying to fall asleep on an airplane or those attempting to reset their sleep cycle after traveling through different time zones.

Sleep restoration: Getting a sufficient amount of deep sleep and rapid eye movement (REM) sleep plays an essential role in a person’s overall health and well-being. Quality sleep can also improve focus and help alleviate stress, as well as lower the risk of accidents at work or on the road. Sleep masks promote more restorative sleep by regulating melatonin production and helping people remain asleep throughout the night.

How to Choose a Sleep Mask

A sleep mask refers to any sleep aid that covers both eyes in order to block out light and improve overall sleep quality. They are normally made from natural or synthetic fabrics, such as cotton, silk, or polyester, and some also feature foam components.

What to Look For in a Sleep Mask

When shopping for a sleep mask and comparing different brands and models, there are a few factors to keep in mind:

Composition

Sleep masks made of natural fibers differ in feel from those made of synthetic fibers, and the same is true of foam-based models.

Effectiveness

Although the difference may seem slight, a sleep mask that blocks out 90% of light will be far less effective than one that blocks out 95% to 99% of light.

Portability

If you plan to use a sleep mask while traveling, a lightweight model that comes with a carrying case may be the best option.

Eye Protection

Some sleep mask wearers don’t mind if their eyes come into contact with the mask, but for those who experience irritation and discomfort, a mask with recessed eye cavities will usually be best.

Band Adjusters

For side sleepers, a mask with plastic or metal band adjusters may cause discomfort by pressing into the side of the head.

Benefits and Drawbacks of Using a Sleep Mask

Some advantages of sleep masks include:

• Low cost: Sleep masks are a less expensive way to block and control light compared with other options such as blackout curtains.
• Lightweight and portable: Even weighted sleep masks typically weigh less than a pound, and most masks are foldable for easier portability.
• Easy to clean: Sleep masks are usually machine-washable or can be washed by hand, avoiding the need for costly dry-cleaning or other specialty cleaning methods.
• Customizable fit: Sleep masks typically feature an elastic band with fasteners or hook-and-loop closures that can be adjusted for a more comfortable fit.
• Breathable: Some common sleep mask materials, such as silk and cotton, are naturally breathable. Additionally, some models are designed with vents to improve air circulation.

Disadvantages of sleep masks may include:

• Adjustment period: Sleepers normally require several nights to acclimate themselves to a sleep mask. The adjustment period may be longer for some individuals, and this can result in poor sleep quality in the meantime.
• Not built to last: Sleep masks should be cleaned frequently, and repeated wash cycles can cause the materials to degrade quickly. Generally, masks with higher price-points have longer lifespans than more affordable options, but this can vary based on the materials used.
• May be uncomfortable for side sleeping: Some sleep masks feature small plastic or metal fasteners on the side of the strap that can cause pain or discomfort for side sleepers, although many models forgo these parts to provide comfort regardless of sleep position.
• Visible effects: Some sleep mask models may result in wear lines around the eyes and cheeks, smudged makeup, or tousled hair.
