During a heat wave, emergencies are most common among the very young, very old and those who are in poor health or on medications. Try to stay indoors, drink plenty of water and frequently check on family members.

Signs of heat exhaustion include cool, moist or flushed skin, sweating, nausea, vomiting, dizziness, and exhaustion. Heat exhaustion can lead to heat stroke. Signs of heat stroke include dry, hot, red skin, changes in consciousness, rapid or weak pulse, and rapid or shallow breathing.

Call 911 immediately if signs of heat stroke occur.
