If you live in a hot or humid area, your body loses more water through sweat, so you need to drink more.

Women who are pregnant or breastfeeding need extra hydration to support their bodies and babies.

Illnesses like fever, diarrhea, or infections increase water loss. In such cases, you need to drink more fluids.
