Sleep Basics

Make Your Sleep Environment Comfortable

Make a few practical changes to light, sound, temperature and bedding so your sleep space feels more supportive of rest.

Start with the light

A darker room may make it easier to settle, especially if streetlights, clocks or device screens interrupt you. The NHLBI recommends keeping the bedroom dark. Close curtains, turn displays away or use an eye mask if those options suit you. Keep a safe path visible if you need to get up during the night.

Reduce the sounds you can control

Notice the sounds that repeatedly wake or distract you, then address the easiest one first. Silence nonessential alerts, close a door or try earplugs if they are comfortable and safe for you. CDC sleep guidance includes a quiet bedroom. If complete silence is impossible, steady background sound may feel less disruptive than unpredictable noise.

Aim for comfortably cool

Many people find a comfortably cool room easier for sleep, but there is no single temperature that suits every person, home or season. NHLBI advises sleeping in a cool, quiet and dark place. Try a small adjustment, such as lighter covers or safe ventilation, and let your own comfort guide the next change.

Check the feel of your bedding

Your mattress, pillow and covers should support a position you can maintain comfortably. The NHS includes comfortable bedding in its sleep advice. Before replacing anything, check whether a pillow needs repositioning, a cover feels too warm or a loose sheet is distracting. Comfort is personal, so use what feels supportive rather than copying someone else’s setup.

Make one simple change at a time

Walk through the room before bed and choose one small, practical adjustment: move a glowing charger, close a curtain or place the phone face down. CDC guidance describes a dark, quiet, cool and comfortable sleep environment. Give the change a few nights, then keep, adapt or remove it. A supportive room can be created gradually, without a perfect setup.
