I’ve written about them before. Eye masks. Those little pieces of fabric that you can place over your eyes to shield out the light and help you get some zzz’s. I have been wearing eye masks to sleep for years. At first, when I started wearing them, I didn’t care for the feeling of elastic across the back of my head. And now? If I am not wearing an eye mask, I don’t sleep well. My head has become accustomed to that feeling, making an eye mask a must-have for me.
I’ve also written about circadian rhythm. That internal-clock-type-thing that tells you when to go to bed and when to wake up. One of the things that can help to maintain that rhythm is dark in the night and light in the day. Wearing a sleep mask to keep out the light can be exceptionally beneficial in this regard.
