Can I sleep in a Lyonshel?
The Lyonshel mask is comfortable enough to wear while sleeping, if you sleep on your back. If you sleep on your side, or otherwise mush your face into the pillow, you will feel the mask pulling against your skin, which may keep you awake. Also, unless you sleep on your back, you’ll probably damage the mask, tearing it, nicking the paint, or putting a permanent dent in it. It can be damaging to your skin to wear the mask for more than 18 hours without taking it off for a few hours to let your skin breathe. Everyone seems to agree that it is best to take the mask off before sleeping.
