There are several ways you can keep cool besides turning the AC down. In addition to great cooling sheets, you can alter a few nighttime behaviors to help your body start cooling down before bedtime. Try taking a warm bath or shower before you go to bed. Your core body temperature will initially rise in the warm water. But once you get out, both evaporation and your body’s desire to regulate its internal temperature will help you cool down. Also, avoid eating heavy meals late at night or snacking right before bed. Digesting food takes energy, which can make you feel warm. To cool down your room, try keeping your blinds shut during the day or even getting blackout curtains to keep the sunlight from raising the room temp. And make sure your ceiling fans are moving counterclockwise to help circulate cool air throughout the room rather than letting it pool on the floor.
