Move the person to a cooler location. Give the person sips of cool water, not ice cold water. If you become ill, faint, have difficulty breathing or feel confused and disoriented, call your doctor. In an emergency, call 911. Use your fan in or next to a window.
Box fans are best.
Use a fan to bring in the cooler air from outside. Use your fan by plugging it directly into the wall outlet. Don't use a fan in a closed room without windows or doors open to the outside. Don't believe that fans cool air. They just move the air around.
