Residents of California, Arizona, and Nevada are being warned to put down their coffee mugs as a record-breaking heatwave grips the Southwest. With temperatures soaring into the triple digits, experts say staying hydrated is more important than ever—and coffee may work against that goal.
The main concern is caffeine, the key ingredient in coffee. Caffeine is a diuretic, which means it makes the body lose fluids more quickly. In extreme heat, this can lead to dehydration, which increases the risk of heat exhaustion or even heat stroke.
“This is about more than skipping your morning cup,” experts say. “It’s about protecting your health in dangerous conditions.” The National Weather Service has issued excessive heat warnings for large parts of California, Arizona, and Nevada. Officials are urging people to take extra precautions, including cutting back on coffee and other caffeinated drinks.
So what should you drink instead? Water is the best option. If plain water feels dull, experts suggest trying electrolyte drinks, fruit-infused water, or chilled herbal teas. These alternatives help the body stay hydrated without the risks that come with coffee in extreme heat.
In addition to choosing the right drinks, experts recommend staying indoors during the hottest parts of the day—typically from late morning to early evening. If you must go outside, wear lightweight and breathable clothing. Stay in the shade as much as possible. Use fans, air conditioning, or take cool showers to help your body manage the heat.
While giving up coffee might feel like a tough change, experts stress that it’s only temporary. Once the heatwave ends, you can return to your daily latte. For now, focusing on hydration and heat safety is the smarter choice.
