A sleeping eye mask's main function is to block out light and create a dark atmosphere, which can aid in promoting deep, unbroken sleep. People who have trouble falling asleep in bright or noisy environments may find the darkness the mask creates to be especially helpful. Melatonin is a hormone that regulates sleep, and the darkness the mask creates helps to trigger its production.
When choosing a sleeping eye mask, it's crucial to take into account aspects like the mask's material, size, and shape, as well as any extra features that might be useful, like adjustable straps or cooling gel inserts. Additionally, it's crucial to pick a mask that is easy to wear and doesn't press against the face or eyes, as doing so can make it difficult to fall asleep.
