The hotter it gets, the more refreshing a beverage seems—including an ice-cold beer or a glass of frosé. But you might want to minimize your alcohol consumption during a heatwave, for safety reasons.
Alcohol dehydrates you, literally. It stops the release of a natural hormone in your body called anti-diuretic hormone (ADH). Normally, ADH keeps you from peeing out too much water. That means that when you drink a lot, you’ll pee a lot, losing even more water than you’re taking in.
That’s not a huge deal if you only have one or two drinks and you make sure to keep hydrated, but the more you drink ,the more dehydrated you’ll get, and the less control you’ll have over your own judgment. So as a safety tip, it’s best to avoid alcohol or keep it to a minimum on very hot days. Dehydration can make it easier to get heat illness, which in extreme cases can be life threatening.
If you’re cooling off in a pool or at the beach, you have to be extra careful. Not to be a buzzkill, but 70 percent of drowning deaths related to outdoor recreation involved alcohol. When you’re drunk, you’re more likely to do stupid things, and your balance and coordination are shot.
So if you’re going to drink at the beach this summer, at least be smart about it. Drink plenty of water, don’t have a ton of alcohol, and stick close to people who are sober enough to notice if you’re putting yourself in danger.
