Common Mistakes to Avoid
- Counting all beverages as equal — caffeinated drinks like coffee and energy drinks have mild diuretic effects; they contribute to hydration but less efficiently than water.
- Using the same amount year-round — hot weather, intense exercise, and illness dramatically increase water needs; adjust your target accordingly.
- Forgetting that food provides water — fruits, vegetables, and soups contribute 20–30% of daily water intake; your drinking target can be adjusted accordingly.
