Where to escape the heat

How to identify heat exhaustion and heat stroke

An extremely high body temperature (103 or higher), dizziness, nausea, confusion, and headache are signs of heat stroke or exhaustion. If someone shows these signs, call 911 and begin cooling the individual. Here’s how:

  • Moving them to a shaded area.
  • Spraying with cool water and fanning them.
  • Placing them in a cool shower if they are alert.
  • Monitoring the body temperature and continue cooling efforts.
  • Do not give the victim fluids to drink.

People age 65 and older, infants and children, and people with chronic medical conditions are more prone to heat stress. People with elderly neighbors should check in on their well-being.
