Exercise: If you are involved in some physical activity that makes you sweat, you need extra water to cover the loss of fluids. When you are working out, have water before, during and after a workout. If you do intense physical activity, you can opt for a sports drink that can help replace minerals lost during a workout.
Weather: Hot and humid weather can make one sweat more and lose more bodily fluids. Sometimes extreme hot weather can also cause dehydration. Thus it’s advised to keep sipping water and other cooling drinks in hot weather.
Overall health: Your body can lose fluids when you get diarrhoea and vomiting. Drink more water and ORS solution in this case. Some other conditions like bladder infections and urinary tract infection might also require you to take more liquids.
Pregnancy and breastfeeding: Women, when pregnant or breastfeeding, need additional fluid to stay hydrated. According to studies, pregnant women should drink about 2.4 litres of fluids and breastfeeding women need 3.1 litres of water every day.
