Staying hydrated is important, but many people still wonder how much water to drink per day. Some follow the “8 glasses rule,” while others drink water only when they feel thirsty. But is that enough?
According to Dt. Shweta Nakra, an experienced dietitian with 12+ years of expertise, your daily water intake depends on multiple factors like age, weight, lifestyle, and even the weather you live in—especially in a city like Delhi.
Why Water Intake Matters for Your Health
Water plays a key role in keeping your body healthy. It helps in:
- Maintaining body temperature
- Improving digestion
- Keeping your skin healthy
- Boosting energy levels
If you don’t drink enough water, your body can feel tired, and you may even experience headaches or low concentration.
Quick Answer: How Much Water to Drink Per Day?
The general recommendation is around 2–3 liters per day, but this is not the same for everyone.
As per Dt. Shweta Nakra, the right amount depends on your body’s needs. So instead of following a fixed rule, it’s better to understand your personal requirement.
Daily Water Intake by Age
Your body’s hydration needs change with age. Here’s a simple breakdown of daily water intake by age:
- Children (5–12 years): 1–1.5 liters
- Teenagers: 1.5–2 liters
- Adults: 2–3 liters
- Elderly: 1.5–2 liters
Older adults may feel less thirsty, so they should consciously drink water throughout the day.
How Much Water Should You Drink Based on Weight
A more accurate way to calculate how much water should you drink based on weight is:
👉 Multiply your weight (in kg) by 30–35 ml
For example:
If your weight is 70 kg → 70 × 30 = 2100 ml (2.1 liters approx.)
This method gives a personalized estimate instead of a one-size-fits-all approach.
Factors That Affect Your Daily Water Intake
Your recommended daily water intake can change based on:
- Weather: In hot cities like Delhi, you lose more fluids through sweat
- Physical activity: More exercise = more water needed
- Pregnancy & breastfeeding: Higher hydration is required
- Illness or fever: Body needs extra fluids
People living in Delhi often need more water due to heat and pollution levels.
Signs You Are Not Drinking Enough Water
Your body gives clear signals when you’re dehydrated:
- Dark yellow urine
- Dry skin or lips
- Headaches
- Feeling tired or dizzy
If you notice these signs, increase your water intake immediately.
