Take extra precautions before working or spending time outside.  Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Wear lightweight and loose-fitting clothes. When possible, reschedule strenuous activities to early morning or evening. The Occupational Safety and Health Administration recommends frequent rest breaks in shaded or air-conditioned environments.
