Pediatrician outlines hydration needs for children amid heatwave

Children are especially vulnerable to dehydration during hot weather and need age-appropriate fluid intake, pediatrician Daria Isetskaya told Gazeta.Ru on Wednesday.

Breastfed infants do not require extra water, while formula-fed babies should receive 30–50 ml of water per kilogram of body weight daily, she said. Children under 12 need around 50 ml per kg, including fluids from food, and teenagers should consume 2 to 2.5 liters a day.

Water — filtered or bottled — remains the best option, Isetskaya said. Herbal teas (from 4–6 months), diluted juices, compotes, fruit drinks, and low-fat milk may also be given in moderation. She advised against sugary and carbonated drinks, as well as black and green tea for young children.

Signs of dehydration include dry diapers for more than 6–8 hours, crying without tears, dry lips, pale skin, or unusual sleepiness in infants. Older children may show weakness, dizziness, and dark yellow urine. Pale urine indicates adequate hydration.

Dehydration can lead to kidney strain, heart issues, cognitive decline, constipation, and digestive problems, Isetskaya warned. She recommended offering small sips of water regularly throughout the day and avoiding drinking immediately before or after meals.
