To feel cool without air conditioning, you must focus on managing your body temperature and optimizing airflow. Start by keeping curtains and blinds closed during the day to block the "greenhouse effect" from sunlight. Use the "cross-breeze" technique at night by opening windows on opposite sides of your home to pull in cooler air. A highly effective "hack" is to place a bowl of ice or a frozen gallon jug directly in front of a fan; this creates a localized "evaporative cooling" effect similar to a swamp cooler. On a personal level, focus on "pulse points" by applying cold water or ice packs to your wrists, neck, and the insides of your elbows, which helps cool the blood circulating through your body. Wearing loose-fitting, light-colored linen or cotton clothing allows your skin to breathe and sweat to evaporate efficiently. Finally, staying hydrated with cold water and avoiding heavy, "heat-generating" meals like stews or large roasts will help keep your internal metabolic temperature lower during the peak heat of the day.
