Check how much water your body needs depending on your age

Our needs for water change with every phase of our lives. Are you a parent of a baby, toddler, are you breastfeeding, or just want to know how much water your body needs every day? This is the right place to find out.

Infants up to six months of age that are fed exclusively by breastfeeding require no additional water, because the mother’s milk provides them with all the necessary nutrients, along with approximately 100–190 ml of water per kilogram of body mass daily.   

The introduction of supplemental feeding begins at 4 to 6 months of age with meals consisting of fruits, vegetables, grains and other food intended for infants, which is in most cases also a period when the baby begins drinking small quantities of water, a few sips at a time. 

For infants aged 6 to 12, the intake of water via mother’s milk (or infant formula), supplemental feeding and drinks reaches a total of 800 to 1000 ml per day, from all sources.  

Children aged 1 to 3

It is well known that healthy habits are acquired from early childhood, and focusing on drinking clean water is one of those decisions that can help you as a parent to make a difference and improve the nutritional habits of your children later in life. For small children from 1 to 2 years of age, the adequate total water intake, including water contained in food, milk, drinks and the quantity taken in by drinking water itself amounts to 1.1 to 1.2 litres per day, while for children from 2 to 3 years of age it amounts to approximately 1.3 litres per day.  

Jana is a great choice of water for children – internationally acclaimed natural mineral water that meets the strict criteria and regulations for bottled water.  Originally sealed Jana, for common use, does not require additional boiling to ensure its purity.  

Children aged 4 to 8

The total water intake needs (from food and drinks) for children of this age increase to 1.6 litres per day. The habit of drinking water is important in relation to other drinks because water drinking has a positive effect on the prevention of dental caries and obesity. 

Children aged 9

Starting from 9 years of age the recommendations for daily water intake differ for girls and for boys.  Girls need 1.9 litres, and boys need 2.1 litres per day. In relation to all other drinks, drinking water should be the first choice for quenching thirst.  

Young people aged 14

Water intake needs for children over the age of 14 are equal to those of adult persons, and the elderly. 


The recommendation for total water intake is 2 litres per day for women and 2.5 litres for men. Take away 20% of water contained in food, it is recommended that women drink approximately 1.6 litres per day, while for men that amount is approximately equal to 2 litres per day.   

Pregnant and lactating women

Apart from the general recommendation of 8–10 glasses of water per day, pregnant women need an additional intake of approximately 300 ml of water per day, which is necessary for the increased blood volume, the amniotic fluid and the circulatory system of the foetus. It is particularly important for mothers to drink enough water after giving birth, so she can feel better and compensate for the water that is necessary for creating a sufficient amount of milk. Thus, mothers who breastfeed need to take in approximately 700 ml of water more than usual.  

Whether it’s those with low mineral content or those rich in minerals, carbonated or non-carbonated, natural mineral waters have their place in everyday, proper and adequate hydration.
