Daily Water Requirement

Water is the basis of life. How much a day should you drink?

Individual water requirements can vary greatly on a day-to-day basis because of differences in:

  • Age.

  • Sex.

  • Physical activity.

  • Climates.

  • Caloric consumption.

  • Dietary contents.

  • The concentrating-diluting capacities of the kidneys.

  • Etc.

There is no single daily water requirement for a given person. There are many reasons why human water requirements are elusive. The dynamic complexity of the water regulatory network and inter-individual differences are the main reasons. So how much water does the average, healthy adult need?

According to The European Food Safety Authority (EFSA) recommended daily water intake for a person who resides in a moderate climate and partakes in normal physical activity is:

  • 1.6 liters for women

  • 2.0 liters for men

Remember to drink enough water to avoid dehydration. Thirst and dry mouth are the first signals your body sends you that you should pay attention to. How much water do you drink daily? Have you ever checked it? Let me know in the comment below.
