Think about the heat forecast as well as the rain forecast. Sweat helps cool your skin as it evaporates. But it can also make your hands slippery and impede your vision. Be extra careful when performing everyday tasks when you're sweaty. Heat exhaustion occurs when you are low on water and electrolytes.
Symptoms are cold, clammy skin and a slowed pulse.
If you think you might have heat exhaustion, stop working. If you start to feel dizzy or sick to your stomach, get out of the sun, drink lots of fluids, and take it easy the rest of the day. You've had too much. Your help, whether hired workers or family members, may hesitate to slow down for heat because they don't want you to think they're wimps.
