Proper water intake significantly affects the body’s overall condition. During pregnancy it is extremely important for both the mother and child. Apart from its beneficial effects in the regulation of physical changes in the body, it can also alleviate discomfort during pregnancy.

In addition to the recommended 8 – 10 glasses of water a day, the daily intake should be increased by about 300 ml. During pregnancy, water is indispensable for the enhanced blood volume, amniotic fluid and fetal circulation.

Babies and nursing mothers

Six-months old or younger babies who are exclusively breastfed need no additional water in their diet. Babies get their necessary nutrients from the mother’s milk, specifically 100 – 190 ml of water daily per kilogram of their body mass.

Therefore, it is extremely important for the mother to drink enough water in order to feel well and to restore the water necessary for producing sufficient amounts of milk. Hence, breastfeeding mothers should take in approximately 700 ml more water than usual.


The recommended daily intake of water for young children aged between 1 and 2 years is 1,1 to 1,2 l. The recommended daily intake of water for children aged 2 to 3 years increases to 1,3 l. The given amount includes water from both food and drinks.

Jana complies with the strict criteria and regulations for bottled water. Originally sealed Jana does not need additional boiling for common use. Healthy habits are acquired in early childhood. Drinking enough water is a habit which really makes a difference in the diet and health quality later in life.

The need for water in children between 4 and 8 years of age increases to 1,6 l a day.

From the age of 9 the recommended levels differ for girls, who need 1,9 l, and boys, who need 2,1 l a day.


Somewhere around the age of 14, our need for water becomes equal to that of an adult. Hence, the recommended daily intake of water for women amounts to 2 l and for men 2,5 l. Approximately 20% of that amount comes from food, which means that women are recommended to drink 1,6 l, whereas men should drink 2 l a day.

Older persons

Older persons are recommended to drink the same amount of water as adults, although their needs for energy are smaller. The renal function, as well as the sensation of thirst, diminish with age. Consequently, older persons are often at risk of inadequate fluid intake, which may have a negative effect on their cognitive functions and motor skills.

The indicated amounts are sufficient for moderate activity and ambient temperature, whereas their increase simultaneously increases the need for water as well. Apart from being an important contributor to physical and cognitive functions, water is also indispensable in maintaining the normal thermoregulation of the body, an aspect where children and older persons are especially sensitive.
