Everyone has heard that you should drink eight glasses of water a day. It is a decent rule of thumb, but it ignores where you live. Jaipur summers regularly cross 40 degrees, and a day spent outdoors or at a shop counter without air conditioning is very different from a day in a cool office.
A sensible starting point
Most healthy adults do well with roughly two to three litres of fluids a day. That includes water, chai, buttermilk, nimbu pani and the water in your food. It is a general guide, not a medical target. Children need less, and people with certain health conditions have been given specific limits by their doctors, which they should follow.
When you need more than that
- You are working or exercising outdoors in the heat.
- You sweat heavily, or you spend long hours in a hot room.
- You are travelling, especially by road.
- You are unwell with fever, vomiting or loose motions (ask a doctor how to rehydrate properly).
Easy signs that you are drinking enough
Do not rely on thirst alone. By the time you feel thirsty you may already be slightly short. A simpler check is the colour of your urine: pale straw means you are doing fine, dark yellow means drink more. Headaches, tiredness in the afternoon and dry lips are also common signs.
Habits that actually work
- Start the day with a glass of water before chai.
- Keep a 1 litre bottle on your desk and aim to finish it twice.
- Drink a glass with every meal.
- Carry a bottle when you leave the house in summer.
- Do not wait for the gym. Sip steadily through the day instead of gulping a litre at once.
Is plain water enough?
For most people, yes. During long hours of heavy sweating, a pinch of salt and some sugar in your water, or ORS, helps replace what you lose. For everyday life, clean plain water is what you need.
If you would like cold, clean water without the daily hassle of refilling, a regular delivery keeps a jar or camper ready at home or work.
