Dehydration Dos and Don'ts

Know how to optimise fluid intake in summer

- FE FEATURES

It's summer, and we often don't realise we need to drink more water to avoid dehydration. Dr Suranjit Chatterjee, senior consultant, internal medicine, Indraprastha Apollo Hospitals, tells us how much water an average office-going person should drink daily during summer. "During the summer months, an average office-going person should aim to drink around 2.5 to 3.5 litres of water daily, depending on body size, activity level, and environmental conditions. Even if one spends most of the day in an air-conditioned environment, the body loses water through sweat, urine, and even breathing. Commuting, walking between locations, or spending brief periods outside in the heat increases water loss. Listening to your body's cues—like dry mouth, fatigue, or darker urine—can help guide your hydration needs."
