Do you need eight glasses? You’ve probably heard it: “Drink eight glasses of water a day.” It sounds simple and easy. But here’s the secret: it’s not a rule. It’s mostly a myth. Everyone’s body is different. The amount of water you need depends on your age, health, activity level, climate, and whether you’re pregnant or breastfeeding. Experts from the National Academies of Sciences say adult men need about 3.7 liters of fluids daily. Adult women need around 2.7 liters. This includes water from drinks and food. Your body obtains approximately 20% of its fluids from food. So, there’s no universal number.
Water Needs for Children and Teens
- Kids need water too, but the amount changes with age. Children aged 1- 3 need about four cups a day. Kids aged 4-8 need five cups. Ages 9-13 need seven to eight cups.
- Teens 14 - 18 may need eight to eleven cups. Boys often need more than girls, and children who play a lot or who are active have more water requirements, as sweating makes them lose water.
- For the first six months, newborns get all the water they require from formula or breastmilk; after that, they can have tiny sips. Children are kept healthy, energized, and focused by drinking water.
Pregnancy and Breastfeeding
- Pregnant women need more water. Daily, approximately 10 cups, or 2.4 liters. Mothers who breastfeed need even more, up to 13 cups or 3 liters.
- In hot weather, lofty locations, or illness, water requirements also increase. Drinking water keeps both mama and baby secure.
- It prevents exhaustion, dizziness, and dehydration. Drinking little amounts frequently rather than a lot at once is preferable.
Indications You are Drinking Enough
- How can you tell if you are hydrated? Look for these easy signals. You probably are drinking enough if you seldom feel thirsty and your urine is a pale yellow.
- Good signals are also having no headaches, thinking clearly, and feeling energized. Drink more water if your urine is dark yellow or if you feel tired or dizzy.
- Furthermore useful is fruit and vegetable consumption. Always follow your body over set rules.

Why Water Matters so Much
- Water is necessary for your body; it is not only for consumption. Your body's cells need water to operate well. It aids digestion, nutrient transport, and waste removal.
- Your body temperature, your joints moving smoothly, and your skin being healthy are all maintained with water.
- Your body could feel tired without adequate water, your concentration might suffer, and headaches or cramps could result.
Helpful Ideas to Drink More Water
Sometimes one forgets to drink. Bringing a water bottle everywhere is a great tip. Rather than guzzling a lot at once, sip a little all through the day. Consume oranges, cucumbers, and water-filled fruits and vegetables. Make phone or watch reminders to drink often. Drinking water before meals can also help you feel full and prevent overeating.
Changing Water Intake
Your lifestyle affects your water needs. You must drink extra water if you exercise frequently or live in warm weather. Your body could also require more liquids if you reside in a cold climate or at a high elevation. Fast water loss can result from even minor ailments like diarrhoea or a fever. The secret is to listen to your body and modify your consumption to maintain hydration.
