Weighted eye masks provide deep touch pressure (DTP). This is a gentle, evenly distributed weight that mimics a comforting hug for eyes. 
The right amount of pressure promotes activation of the parasympathetic nervous system, lowering cortisol while increasing serotonin and melatonin to help you unwind and fall asleep faster and for longer. They also offer light-blocking benefits, supporting melatonin production  and regulation to help you rest up better and wake up sharper.
