Keep in mind you may need to adjust your plans based on the latest health and safety guidelines from CDC and your local officials. Cooling shelters may need to take your temperature or ask questions about how you are feeling. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible.
