The New Yorker: There are a number of simple ways to improve sleep quality, including purchasing a new mattress, paying attention to your sleep position, and reducing nighttime light exposure.

Warm up for bedtime by practicing your optimal sleep position, whether that’s on your back, side, or stomach. We highly recommend preparing your body to withstand the grueling inactivity that, in some cases, can last all night.
