A. Anyone who sleeps during the day needs to make sure their room is dark – use heavy window coverings to block out the light. This is important for everyone, but particularly for people who sleep when it's bright outside. Also, make sure your room is cool, between 60 to 65 degrees Fahrenheit (16 to 18 degrees Celsius). Sleep on a comfortable, supportive mattress and foundation that offers you enough space to move around comfortably. And sleep in a room that's quiet. The sleep environment is a very controllable part of good sleep – whether you're sleeping during the day or at night. You can adjust the temperature, replace an uncomfortable or worn-out mattress, block out noise with earplugs or a white noise machine and keep light from your bedroom with dark blinds or eye shades.
