Fluid intake recommendations

Fluid intake recommendations suggest adults generally need about 8 cups (around 2 liters or half a gallon) of water daily, but needs vary based on factors like age, activity level, climate, and health. Proper hydration supports vital functions such as maintaining body temperature, digestion, and joint lubrication. It’s best to drink when you feel thirsty and pay attention to your body's signals. Besides water, other beverages and high-water foods like fruits and vegetables contribute to hydration. Staying well-hydrated helps prevent dehydration, which can affect energy, mood, and overall health.
