Half Moon Silk Eye Mask Putting on silk sleep mask like this one from Half Moon ($38) helps me feel more calm as I try to fall asleep. It sets the tone that the day is done, I should leave my worries behind and get ready to relax. I love that the fabric is breathable and naturally cooling and the shape is oversized for maximum darkness. Image Source: Genevieve Farrell Half Moon $38 from shophalfmoon.com Buy Now
