7. You can get under-eye bags.
If you lie on your stomach, liquid can pool in the trough of your under-eye throughout the night and cause puffiness that you won’t want to wake up to. To combat this, slip on a thick sleep mask, like the Mumbani Sleep Mask, that’ll help prop up your head to keep the fluid in your body flowing downward, instead of pooling under your eyes. If you’re reading this and currently have under-eye bags, grab two soaked green tea bags and rest them under your eyes for five minutes to help reduce the puffiness.
