Do people in humid climates drink less water?

Staying Hydrated in Humid Climates

When the air feels thick and sticky, it is easy to assume your body needs less fluid because you aren't sweating as much. In reality, the opposite is true. While mild conditions typically call for six to eight glasses of water daily, high humidity actually increases your body's need for hydration.

Humidity disrupts the body's natural cooling mechanism. When the air is saturated with moisture, sweat cannot evaporate efficiently from your skin, leaving you feeling warmer and prompting your body to work harder to cool down. To support this process, a practical rule of thumb is to add one or two extra glasses of water on particularly humid days.

Of course, your individual requirements depend heavily on your lifestyle. If you are exercising outdoors or moving around frequently in the heat, you will need to adjust your intake even further. Listening to your body and keeping a water bottle close at hand ensures you stay energized and healthy, no matter how muggy the weather gets.
