Heat, Cold & Environment

In an emergency, call 911 first (or your local emergency number). If someone is unresponsive and not breathing normally, start CPR and send for an AED. Do not delay a call to read a guide.

Heat exhaustion and heatstroke, hypothermia, frostbite, cold water shock, altitude sickness, dehydration and lightning: how weather and environment injure, and the first aid that reverses it.

8 guides in this section. Select one for numbered first-aid steps, what not to do, and when to get medical care. Every guide prints as a clean one-topic sheet.
