How much water should you drink per day? (Hydration) Let's find out exactly what this is!

We've all been told since we were little that we should drink at least 8 glasses of water a day. Your parents, teachers, and even your school teachers have probably told you this all the time. But is this really true for everyone? Is it true that everyone drinks 8 glasses of water a day? Simply put, the answer is 'no'. The amount of water your body needs depends on many factors, including your age, your activity level, and the climate. So today, let's talk about exactly this, how to drink water that suits you.

Why is water so important for our bodies?

Just think, about 60% of your body weight is water. That means water is essential for every process and every cell in our body. It's like gasoline for a car.

Simply put, water does many important things inside our bodies, including:

  • It flushes out toxins from our organs.
  • We carry the nutrients in the food we eat into our cells.
  • It acts as a cushion for our joints and protects them.
  • It helps us digest the food we eat.

If you don't drink enough water, you can become dehydrated . This means that your body doesn't have enough water. While normal dehydration can cause symptoms like fatigue and headaches, more serious conditions like dizziness, confusion, and seizures can occur. Therefore, it's important to drink enough water every day.

So how much water do we need per day?

That '8 glasses' thing we talked about earlier isn't really a rule. It's just a general guideline. The amount of water each person needs is actually different. However, the Institute of Medicine (IOM) has made some recommendations about this.

Person Recommended daily fluid intake
For men About 13 cups (about 3 liters)
For women About 9 cups (a little over 2 liters)
Pregnant mothers About 10 cups
Breastfeeding mothers About 12 cups

These amounts include not only the water you drink , but also the liquid in things like tea, coffee , fruit drinks, and soup. But we'll talk about that later.

The most important thing is not to worry too much about these numbers. It's best to listen to your body.

If you're doing a lot of exercise that makes you sweat , or if you're working out in the heat, you 'll need to drink more water than usual. You also need to drink more water when you have an illness like fever, vomiting , or diarrhea , as your body loses a lot of fluid.

Special Note: If you have heart failure or certain kidney conditions, you may need to limit the amount of fluid you drink per day. So, if you have any of these conditions, be sure to talk to your doctor about what amount is right for you.

How should you give water to young children?

The amount of water needed by adults and children varies depending on factors such as age, weight, how active they are, and climate.

  • On average, children and young children need between 6 and 8 cups of water per day.
  • A child between the ages of 1-3 needs about 4 cups of water a day.
  • A child between 4-8 years old needs about 5 cups.

When children are playing, it is a good idea to give them half a cup or two of water to drink every 15-20 minutes.

Most important: Babies under 6 months old

Do not give plain water to babies under 6 months of age for any reason. A baby's stomach is very small. If you give water, that small stomach will fill up with water. Then they will lose the space to drink breast milk or formula, which is essential for their growth. Therefore, the baby will get all the water they need from breast milk or formula.

Can you really lose weight by drinking water?

This is a question that many people ask. Yes, there is some evidence that drinking water can help with the weight loss process. Here's how:

  • Speeds up metabolism: When you drink water, especially cold water, your body has to expend extra energy to bring it to body temperature. This can help you burn calories a little faster.
  • Gives a feeling of fullness: Some studies show that drinking two glasses of water before a meal reduces food intake by about 22%.
  • A substitute for high-calorie drinks: When you drink water instead of sugary drinks, soda, and fruit drinks, you can significantly reduce the amount of unnecessary calories you consume per day. Because water has zero calories.

But remember, you can't lose a lot of weight by drinking water alone. But drinking plenty of water along with a healthy diet and exercise will go a long way toward helping you reach your goals.

What happens if you drink these things instead of water?

The amount of fluid you should drink per day includes not only water, but also other drinks and food. But there are some things you need to be careful with.

Type of drink What to know
Coffee and tea Although these provide water, the caffeine can cause the body to excrete more urine. For a healthy person, 2-4 cups of coffee a day is not a problem. But if you feel jittery, cut back.
Alcohol Although things like beer and wine also contain water, these can cause even more water to be lost from the body and lead to dehydration.
Sports Drinks It helps replace electrolytes lost through sweat during intense exercise. However, it can be high in sugar and calories. Read the label and use only when necessary.
Energy Drinks These are different from sports drinks. They contain a lot of sugar and caffeine. They are not recommended for children and young people.
Foods high in water Fruits and vegetables like cucumbers, lettuce, and watermelon are over 90% water. Soups and gravies are also good.

What happens if you drink too much water? (Water Intoxication)

It's very rare for a healthy adult to drink too much water with a normal diet, but it can happen.

If you drink too much water at once, but your kidneys can't get rid of the extra water, you can develop a condition called hyponatremia . Simply put, minerals like sodium in the blood become diluted, causing sodium levels to drop dangerously low. This can be life-threatening. This is especially true for athletes who run long distances, such as marathons.

If you have thyroid disease, kidney, liver, or heart disease, or are taking medications such as certain pain relievers (NSAIDs) and some antidepressants, ask your doctor about the appropriate amount of water for you.

How do I know if I'm drinking enough water?

There are two simple ways to do this.

1. Do you feel thirsty all the time? If you don't feel thirsty all the time, it means you're probably drinking enough water.

2. What color is your urine? If your urine is light yellow or clear, that's a good sign. If it's dark yellow or orange, it means you need to drink more water.
