Staying Hydrated: Simple Daily Habits for Hot Days and Busy Ones

It is easy to go half a day without a proper drink of water. You have tea in the morning, get busy, skip the bottle because the office cooler is on another floor and suddenly it is four o'clock and you have a dull headache. Staying hydrated is not complicated, but it rarely happens by accident. A few small habits make it automatic.

How much is enough?

There is no single number that suits everyone. How much water you need depends on your body size, how active you are, the weather and what you eat. Someone working outdoors in Nagpur in May needs far more than someone in an air-conditioned office in Bengaluru in December. The familiar advice of eight glasses a day is a rough starting point, not a rule.

A more useful guide is your own body:

• Your urine should be pale yellow for most of the day. Dark yellow usually means you need to drink more.
• Thirst is a signal worth listening to, not something to push through.
• If you sweat a lot, from heat, work or exercise, you need extra water on top of your usual amount.

If you have a kidney, heart or other condition where a doctor has advised limiting fluids, follow that advice rather than general tips.

Make water the easy option

Most people do not avoid water on purpose. They simply do not have it within reach.

• Keep a filled bottle on your desk, in your bag and by the bed. If you can see it, you will drink from it.
• Refill the bottle at set points: when you arrive at work, after lunch and before you leave.
• Drink a glass when you wake up. Your body has gone several hours without fluid.
• Pair water with things you already do, such as a glass before each meal or whenever you make tea.
• A clay pot at home keeps water pleasantly cool without a fridge, and many people find they drink more when it is not ice-cold.

Count what you eat and drink, too

Water is not the only source of fluid. Tea and coffee count, although it is sensible not to rely on them entirely. Many everyday foods and drinks are also mostly water:

• Buttermilk (chaas), lassi and nimbu pani.
• Coconut water, which is also a good source of potassium.
• Fruits such as watermelon, muskmelon, oranges and cucumber.
• Dal, rasam, soups and curd.

Sugary soft drinks and packaged juices do add fluid, but they also add a lot of sugar. They are better as an occasional treat than as your main drink.

Hot weather needs a plan

Indian summers can push the body hard, particularly during heatwaves. On very hot days, drink regularly through the day rather than a lot at once in the evening. Carry water whenever you step out, even for short errands, and try to stay indoors during the hottest hours, roughly noon to four in the afternoon, when you can.

When you sweat heavily, you lose salts as well as water. A homemade drink such as nimbu pani with a pinch of salt and a little sugar, buttermilk with salt or a packet of oral rehydration solution (ORS) mixed exactly as the pack says helps replace them. ORS is also what doctors recommend for diarrhoea and vomiting, which cause fluid loss quickly, especially in children and older adults.

Watch the people who forget to drink

Some people are more likely to become dehydrated without noticing:

• Older adults often feel less thirsty, even when their body needs water.
• Young children may be too busy playing to ask.
• People who work outdoors, such as delivery workers, labourers and traffic police.
• Anyone who is unwell with fever, diarrhoea or vomiting.

Offer water regularly rather than waiting to be asked. For an elderly parent, a marked bottle that should be finished by lunch and another by evening can be an easy way to keep track.

Know the warning signs

Mild dehydration often shows up as thirst, a dry mouth, tiredness, headache and dark urine. Drinking water and resting in a cool place usually helps. Signs that need prompt medical attention include confusion, fainting, a very fast heartbeat, very little or no urine for many hours, or, in hot weather, hot dry skin with a high body temperature. These can point to heatstroke or severe dehydration. Get medical help quickly in such cases.

Frequently asked questions

Can you drink too much water?

It is possible, though uncommon. Drinking very large amounts in a short time can upset the body's salt balance. Spreading your intake through the day and following your thirst avoids this.

Does tea or coffee dehydrate you?

In normal amounts, tea and coffee still add to your fluid intake. Very large quantities of caffeine can make you pass urine more often, so it is best to have water alongside them.

Is cold water bad in summer?

Cold water is fine for most people. Some find cool or room-temperature water easier to drink in large amounts, which is why a clay pot is a popular choice.

Small sips, all day

Hydration is less about big targets and more about steady habits. Keep water close, drink before you feel parched, lean on buttermilk and fruit in the heat and keep an eye on the people around you who might forget. Your body will thank you by the end of the afternoon.
