The National Weather Service has issued warnings for millions across 11 US states due to dangerously hot conditions.
Residents in affected areas are advised to avoid alcohol and caffeine, which can accelerate dehydration, and instead drink water or sports drinks.
The warning covers states including California, Nevada, and Arizona, with some experiencing extreme heat warnings and predicted triple-digit temperatures.
Vulnerable groups, such as older adults, young children, and those with chronic conditions, are most susceptible to heat-related illnesses.
Health authorities recommend precautions like wearing light clothing and using sunscreen, while the Red Cross advises mental health care and healthy habits during and after heatwaves.
