If the summer temperatures and humidity is messing with your sleep, you're not alone. Here are five tips to help you stay cool and sleep soundly, even during the hottest summer nights. Try closing the blinds to reduce heat buildup during the day. Insulated cellular shades can slash solar heat that comes through windows by up to 60%.  Try to avoid stressful activities, heavy meals, and intense exercise in the evening, as they make our bodies feel hotter.  If you don't have AC, place a bowl with cold water and ice in your bedroom. Positioning a fan behind it will amplify its cooling effects.  If you live in an area where it's hot and humid, try to keep the humidity at or below 50-60% using a dehumidifier. A warm or lukewarm shower one to two hours before bed can significantly improve sleep, as it can trigger a natural cooldown effect.
