In July, the National Weather Service issued multiple heat warnings and encouraged people to stay indoors in air-conditioned spaces, especially during the day, and to stay hydrated.

Officials said 71% of all heat-related deaths in 2023 occurred on a day when an excessive heat warning was issued. Ignoring safety guidelines on extremely hot days can be fatal.

4 hikers die in Arizona

Last week, 10-year-old hiker Cortinez Logan died after hiking a South Mountain trail at 2 p.m. The high July 2 was 113 degrees.

At the Grand Canyon, three men have died in the last month while hiking and lodging at the national park.

The hikers included a 41-year-old man who died June 16 near the Bright Angel Campground, 69-year-old Scotts Sims from Texas who died June 29 on the South Kaibab Trail, and a 50-year-old Texas man who died July 7. He was found just 100 meters below the Bright Angel Trailhead.

All three deaths are still under investigation.

In Phoenix, city officials have made an effort to curb the dangers associated with hiking in the heat.

While excessive heat warnings are issued, Camelback Mountain's Echo and Cholla trails and all trails associated with Piestewa Peak Trailhead in the Phoenix Mountains Preserve will close from 9 a.m. to 5 p.m. ​ Some trails host extended hours open until 11 p.m. to help people avoid trails when it is too hot.

How do I know if I'm overheating?

The 2023 heat-related deaths report found people who are over 50 years old, experiencing homelessness or have a history of physical or mental health issues are most at risk for heat-related illness.

Heat exhaustion happens when your body overheats and can be caused by strenuous physical activity.

Symptoms of heat illness can include muscle cramps and heavy sweating. Rapid pulse, dizziness, headache, and cool, moist skin with goosebumps while in the heat are also signs of heat exhaustion.

People experiencing these symptoms are advised to stop all activity and rest, move to a cooler place, and drink water or sports drinks.

Serious conditions of heat exhaustion can lead to heatstroke, a more serious heat illness that can be fatal.
