Heat Safety for Hot Summer Days

A practical guide to hydration, outdoor planning, and recognizing warning signs of heat-related illness during hot weather.

High temperatures can affect anyone, but young children, older adults, pregnant people, outdoor workers, and people with certain medical conditions may be at higher risk. A heat plan is especially important during days with high humidity.

Build a simple heat plan

  • Drink water regularly and do not wait until you are thirsty.
  • Schedule strenuous outdoor activity for cooler morning or evening hours when possible.
  • Take frequent shade or air-conditioning breaks and wear lightweight clothing.
  • Check on family members, neighbors, and friends who may need help staying cool.
  • Never leave a child or pet in a parked vehicle.

Know when symptoms need attention

Heavy sweating, dizziness, nausea, headache, weakness, or muscle cramps can be signs that the body is struggling with heat. Move to a cool place, rest, and sip fluids if the person is awake and able to drink.

Call 911 for confusion, fainting, loss of consciousness, seizures, or a very high body temperature. These can be signs of heat stroke and require emergency care.

Talk with your care team

If you take regular medications or have a heart, lung, kidney, or metabolic condition, ask your clinician whether hot weather changes any part of your care plan.
