According to the Centers for Disease Control and Prevention (CDC), active individuals should drink 8 ounces of water every 15–20 minutes when working or exercising in high temperatures. Understanding how often should you drink 8oz of water in heat is crucial for preventing heat-related illnesses and maintaining optimal bodily function.

Contrary to the long-standing myth that coffee is dehydrating, modern research shows moderate consumption doesn't significantly impact hydration. However, the relationship between caffeine and hot weather is more nuanced, involving effects on body temperature, fluid balance, and exercise performance.

According to the Centers for Disease Control and Prevention (CDC), you should drink 8 ounces of water every 15 to 20 minutes when working in hot environments. This critical hydration is essential to counteract the significant fluid loss experienced during 90 degree weather, which can lead to rapid dehydration if not managed properly.

In hot weather, your body loses fluids much more rapidly through sweat than it does on a cool day. Your specific hydration needs in 90-degree heat will vary depending on your activity level, but generally, you need significantly more than the standard eight glasses per day.

According to the Centers for Disease Control and Prevention (CDC), drinking 1 cup (8 ounces) of water every 15–20 minutes is recommended when working in the heat to prevent heat-related illness. Following specific guidelines on how much water to drink when in the sun is crucial for regulating body temperature, maintaining energy levels, and avoiding dangerous health complications.

During prolonged exercise in the heat, high carbohydrate solutions can impair gastric emptying, slowing the absorption of crucial fluids. This raises the critical question of whether the carbohydrate concentration of a sports drink should be less than 8% during exercise in the heat to maintain hydration and performance.

At temperatures above 40°C, a human's resting metabolic rate can increase as the body works harder to maintain its core temperature. This fundamental physiological process provides a critical insight into what happens to metabolism in hot weather.

Studies show that during prolonged exercise in the heat, the body's reliance on carbohydrates increases significantly. This phenomenon raises a critical question for athletes and outdoor workers: are carbs good for heat exhaustion, and what is the safest way to consume them?
