Extreme heat can turn routine summer activities into emergencies, from hiking and yardwork to long drives and outdoor jobs. The American Red Cross of Southern Nevada is sharing steps residents can take to stay safe as temperatures rise.

Extreme heat is the leading weather-related cause of death in the United States, claiming more lives each year than hurricanes, floods and tornadoes combined. The CDC estimates that heat kills about 2,000 people annually, with deaths reaching 2,414 in 2023 and 2,394 in 2024, the two highest years on record.

“Heat-related illness can happen quickly, especially when people are active outside or do not have a cool place to recover,” said Rachel Flanigan, Executive Director of the American Red Cross Southern Nevada Chapter. “A few simple steps, drinking water, taking breaks, checking on others and knowing the warning signs, can help prevent a dangerous situation from becoming life-threatening.”

Stay hydrated, stay cool, stay connected

The Red Cross recommends taking these steps when temperatures rise:

• Stay hydrated: Drink water regularly and do not wait until feeling thirsty. Avoid alcohol and limit drinks with too much caffeine, which can contribute to dehydration.
• Stay cool: Spend time in air-conditioned places when possible. Avoid strenuous outdoor activity during the hottest part of the day and take breaks in the shade or indoors.
• Dress for heat: Wear lightweight, loose-fitting, light-colored clothing. Use sunscreen with SPF 30 or higher and reapply as needed.
• Check on others: Stay in contact with older adults, people with medical conditions, neighbors without air conditioning and anyone who may need help staying cool.
• Use caution in vehicles: Never leave children, pets or anyone with limited mobility in a parked vehicle, even briefly. Temperatures inside a vehicle can rise quickly, even when the windows are cracked.

Know the signs of heat illness

Heat cramps, heat exhaustion and heat stroke can develop when the body cannot cool itself fast enough. Warning signs can include muscle cramps, heavy sweating, weakness, dizziness, nausea, headache, fainting or confusion.

• Heat cramps can cause muscle pain or spasms, often in the legs or abdomen. Move to a cooler place, rest and drink water or a sports drink.
• Heat exhaustion can include heavy sweating, weakness, nausea, dizziness, headache or fainting. Move the person to a cool place, loosen tight clothing and have them sip water slowly. Seek medical help if symptoms worsen or do not improve.
• Heat stroke is life-threatening. Warning signs can include a body temperature of 103°F or higher, confusion, loss of consciousness, hot or red skin, rapid pulse or vomiting. Call 911 immediately and begin cooling the person with water, ice packs or cool cloths until help arrives. 

Prepare before the hottest days arrive

Residents can prepare now by identifying cool places to go, checking air conditioning or fans, keeping extra water available and reviewing plans for outdoor work, recreation and travel. Anyone who works or spends long periods outside should take frequent breaks, watch for symptoms and check on others who may be showing signs of heat illness. To learn more, visit redcross.org/heat.
