Sleep masks are a popular tool for improving sleep quality, but do they actually work? Our internal clocks regulate the sleep-wake cycle, and light exposure at night can affect these natural processes. Researchers have studied the impact of wearing a sleep mask to block out light while sleeping, and results have shown enhanced alertness, memory, and cognitive function the following day. Sleep masks can also help reduce distractions and improve skin hydration, but their effectiveness varies from person to person. Some alternatives to sleep masks include blackout curtains, silk pillowcases, lifestyle changes, and herbal treatments.

Sleep masks improve alertness and memory
Light exposure at night affects the natural processes that help prepare the body for sleep. Our internal clocks regulate the sleep-wake cycle, and light establishes when we should feel wakeful or sleepy. Light exposure at night affects these natural processes, so researchers studied whether wearing an eye mask while sleeping might help with learning and alertness.
A study published in the journal Sleep in December 2022 showed that wearing an eye mask improves alertness and memory. Researchers had a group of people aged 18-35 wear eye masks every night for a week, followed by another week in which light was not blocked from their eyes at night. At the end of each week, they were given a series of tests. Results showed that using an eye mask to block light improved alertness, reaction time, and memory.
In another experiment, participants wore a device that monitored their sleep and a light-blocking mask or one with holes cut out over the eyes. In subsequent cognitive tests, those who wore a light-blocking eye mask performed better on the tests than those who did not.
In a study by researchers from Cardiff University in the United Kingdom, 90 healthy young adults aged 18 to 35 alternated between sleeping while wearing an eye mask or being exposed to light at night. They recorded their sleep patterns in a sleep diary. The participants wore an intact eye mask for a week, then during the next week, they wore an eye mask with a hole exposing each eye so that the mask didn't block the light. After sleeping with no light exposure (wearing the intact eye mask) and with minimal light exposure, participants completed three cognitive tasks on days six and seven of each week. Participants performed better after wearing an intact eye mask during sleep in the days leading up to the test than after being exposed to light at night.
Blocking out ambient light improves sleep quality, which is generally associated with improved cognition. Light exposure during sleep has longer-term negative health impacts, and light at night is even a risk factor for cardiometabolic diseases, including diabetes and insulin resistance.

They help block out light distractions
Light exposure at night affects the natural processes that help prepare the body for sleep. Our internal clocks regulate the sleep-wake cycle, and light exposure determines when we should feel awake or sleepy.
Sleep masks are a cheap, easy solution to block out light distractions. They are available in a variety of shapes, sizes, and materials. For example, silk cloth masks are a good option for those with sensitive skin, while weighted eye masks are ideal for those who enjoy the feeling of a weighted blanket.
Dr. Samuel Gurevich, a sleep expert, says that anyone could benefit from wearing a sleep mask, especially if you don't have blackout curtains, have insomnia, or work the night shift. He adds that a sleep mask can be part of a calming bedtime routine that conditions your brain to recognize that it's time to sleep.
In a study by researchers from Cardiff University in the UK, 90 healthy young adults aged 18 to 35 alternated between sleeping while wearing an eye mask and sleeping with light exposure at night. The results showed that participants who wore eye masks displayed enhanced alertness and memory encoding the following day.
In another study, researchers tracked sleep objectively using a monitoring device called the Dreem headband. They found no changes to the structure of sleep when participants wore eye masks. However, it's important to note that the impact of light at night goes beyond sleep. Light exposure at night is associated with an increased risk of developing depressive symptoms, obesity, diabetes, and high blood pressure.

Masks can be part of a calming bedtime routine
Sleep masks can be a great addition to your bedtime routine, helping to calm you and prepare your mind and body for sleep.
The simple act of wearing a sleep mask can help to block out light, reducing distractions and minimising the impact of light exposure on your body's natural processes. Light exposure at night affects the production of melatonin, a hormone integral to the regulation of sleep. By blocking out light, a sleep mask can help to condition your brain to recognise that it is time to sleep, improving your sleep quality and enhancing your alertness and memory the next day.
Sleep masks are particularly useful if you don't have blackout curtains, or if you work a night shift and sleep during the day. They can also be beneficial if you suffer from insomnia, helping you to fall asleep faster and increasing the amount of sleep you get.
When choosing a sleep mask, opt for one that feels comfortable for you. Consider the fabric, with options including silk, cashmere, cotton, velvet, and fleece. Silk masks are a good choice for those with sensitive skin, while gel masks can help if you enjoy the feeling of cold pressure. Weighted masks provide a heavy sensation, and cushioned masks tend to fit the contour of your face better, blocking out light more effectively.
In addition to improving your sleep, sleep masks can also offer benefits for your skin and mental health. For example, wearing a silk eye mask can help to reduce wrinkles and improve the absorption of skincare products. Overall, incorporating a sleep mask into your bedtime routine can be a simple and effective way to enhance your sleep quality and overall well-being.

Masks can improve skin and sleep patterns
Sleep masks can improve skin health and sleep patterns. Masks made from breathable materials can prevent skin irritation and eye dryness. Silk sleep masks, in particular, can act as a protective barrier, preventing bacteria and oils from your pillowcase from coming into contact with your skin. This can help prevent breakouts and protect against skin conditions such as eczema and psoriasis. Silk masks can also help reduce friction caused by tossing and turning, minimising inflammation and improving the appearance of your skin.
Sleep masks can also improve sleep patterns by blocking out light and creating a calming environment. This can promote the production of melatonin, the sleep hormone, and help you fall asleep faster. A sleep mask can be especially useful if you work night shifts or irregular hours, helping you adjust to different time zones and varying light conditions.
Research supports the effectiveness of sleep masks in improving sleep quality. A study published in the journal Sleep in December 2022 found that wearing an eye mask improved alertness, reaction time, and memory. Another study from Cardiff University showed that participants who wore an eye mask while sleeping performed better on cognitive tasks than those exposed to light at night.
When choosing a sleep mask, opt for one that is comfortable and made from breathable, hypoallergenic materials to prevent skin irritation. Ensure that the mask fits snugly and is not too tight, especially if you sleep on your side. It is also important to keep your sleep mask clean to maintain proper hygiene.
Overall, sleep masks can be a valuable tool to improve skin health and sleep patterns, ultimately enhancing your overall well-being.
