An eyemask can be a great tool for blocking out excess light when you’re trying to sleep. If you need to block out a lot of light, choose a thicker mask. On the other hand, if you’re not facing a lot of light, a thin mask may do just fine. Choose a mask that suits your sleeping position. For example, if you sleep on your back, avoid masks that cling to the back because they can irritate your scalp. Choose a mask that fits you well and is made of a comfortable fabric. If your mask is adjustable, put it on and properly adjust it before trying to sleep. Relax before bed by wearing the mask pushed to your forehead so you have time to get used to it. When you’re ready to sleep, pull down your mask. If the mask distracts you and makes it difficult to fall asleep, try deep breathing or focusing on relaxing imagery to help you.
