You may need more water than anyone else. How much water you need also depends on:

You will need plenty of water in hot, humid, or dry areas. You will also need more water if you live in the mountains or at a very high altitude.
If you drink a lot of coffee and other caffeinated beverages, you may lose a lot of water with more urination. You will also need to drink plenty of water if your food is filled with salty, spicy, or sugary foods. Instead, more water is needed if you don’t eat a lot of water-based foods such as fresh or cooked fruits and vegetables.
