How Much Water Do You Need to Drink a Day?

Water is essential for human life. We need water to survive and our bodies are made up of mostly water. It's important that we drink enough water every day to stay hydrated and healthy. In this blog post, we will discuss how much water you should drink each day and some tips on how to make sure you're getting enough water!

How to know the amount of water per day?

If you do a quick search on the internet, what you'll mostly find is ready-made information, usually indicating 2 to 4 liters a day. This information is not wrong, however, it is incomplete. But why?

Each organism has its own characteristics and needs. As with nutrients – for example, some people have a greater need for iron, due to genetic or biological factors.

What's more, when you look for a nutritionist to assemble a healthy diet, he will assess your body's needs. And with water it's the same thing: your body will have a demand of its own that needs to be fulfilled.

Today, the most adopted measure and considered the most correct by health professionals is the calculation of water consumption according to weight and age.

How to calculate the amount of water per day?

Now that you know that the correct way to know how much water you need to drink per day is from your age and weight, it's time to know how to do this calculation. Spoiler: it's super simple and easy to do. First, let's go to the table:



So, let's take an example: a 30-year-old person who weighs approximately 75 kg. She needs 35 ml for every kg. So: 35 ml x 75 kg = 2.60 liters of water per day. Is it easy to know now how many liters of water we should drink a day?

However, attention is needed: experts recommend that if you practice physical activities frequently and with high impact/effort, you need to ingest 500 ml to 1 l of water for every hour of exercise practiced.

What are the benefits of drinking plenty of water?

To say that water is essential for our health and quality of life is an understatement. All biochemical processes involve this important nutrient and it is necessary for various reactions in our body. But to summarize:

  • Helps balance and regulate body temperature;
  • Assists in the absorption of nutrients;
  • Fundamental to the beauty and health of the skin – our largest and most exposed organ;
  • Essential for the detoxification process and hormonal regulation;
  • Prevents problems in the urinary system – such as the dreaded kidney stones;
  • Improves blood circulation, preventing cardiovascular problems, among others.

Despite being so important, drinking water is unfortunately very neglected by people. And the consequences for your health (in the medium and long term) are devastating. Migraines, constipation, gastrointestinal diseases, insomnia, skin problems, and many others can be sequelae caused by dehydration.

Water is such an important part of our lives, so it's essential that we make sure to drink enough water every day. Cheers to water! 🥂💧
