How to Keep Your Child Safe in a Heatwave?
Summer is a time of carefree fun, fruity ice lollies and long days spent in the fresh air — but when the heat becomes extreme, the holiday idyll can quickly turn into a health risk for the little ones. A young child's body is not yet able to regulate temperature as efficiently as an adult's, making them especially vulnerable to intense sun and stifling heat. However, you don't need to spend the entire summer locked away in an air-conditioned room — a few smart precautions are all it takes to make sure those sunny days stay safe, refreshing and full of joy.
Why is a Heatwave Dangerous for Children?
A child's body is still learning to regulate its temperature, which means it copes with extreme heat far less effectively than an adult's. Young children — and babies in particular — sweat considerably less, causing their bodies to overheat rapidly and significantly raising the risk of dangerous heat stroke. High temperatures also accelerate fluid loss, which in a small child can lead to life-threatening dehydration very quickly. For this reason, summer heatwaves must be treated with great care, with close and continuous attention paid to how the youngest children are feeling.
How to Keep Your Child Safe in a Heatwave? – 6 Proven Tips
Protecting your child from overheating doesn't have to mean giving up summer fun or staying indoors all day. Here are 6 tips to help you get through the hottest days comfortably and safely.
Choose Breathable Clothing
When temperatures soar, avoid synthetic, non-breathable fabrics that cling to the skin and make children sweat more. The best choice for your child is loose, light-coloured clothing made from natural fabrics such as breathable cotton, soft muslin, linen or cooling bamboo. At home, you can comfortably let a baby wear just a nappy (ideally an eco-friendly one) or go nappy-free altogether, giving their skin some relief and helping to prevent painful nappy rash. Also remember to avoid overheating at night!
Keep Your Child Well Hydrated
On hot days, drinking water regularly is an absolute priority, so your child's favourite water bottle or cup should always be within easy reach. Breastfed babies under six months of age generally don't need additional water, but nursing mothers should remember to feed very frequently and to stay very well hydrated themselves. For older children, it's a good idea to vary fluid intake by offering not only plain water but also electrolyte drinks after active play and fruits with a high water content. To make sure your little one is getting enough fluids, it's worth following the daily intake guidelines below, tailored by age and weight.
Approximate daily fluid intake recommendations by age:
|
Child's Age |
Daily Fluid Requirement |
Notes |
|
Infants (up to 6 months) |
approx. 700–1000 ml |
Breast milk or formula is sufficient. |
|
7–12 months |
800–1000 ml |
Time to introduce additional water. |
|
1–3 years |
approx. 1150–1300 ml |
Of which approx. 500–600 ml should be plain water. |
|
4–8 years |
approx. 1600 ml |
Ensure constant access to a water bottle. |
|
9–13 years |
1900–2100 ml |
Approx. 1900 ml (girls) to 2100 ml (boys). |
Avoid Direct Sun Exposure
Going out in full sun between 11:00 and 15:00 is the quickest route to heat stroke, so plan summer activities outside of the midday heat — early in the morning or in the late afternoon. If you do need to go out during the middle of the day, always seek deep shade and make sure your child is wearing a breathable hat with a brim. Crucially, never cover a pram hood with a blanket or muslin cloth, as this creates a dangerously hot greenhouse effect inside, cutting off airflow and sending the temperature to deadly levels. Instead, create safe shade using a pram parasol or a breathable sun sail, and when travelling by car, use breathable bamboo inserts for the car seat.
Use the Right Sun Protection Cream
Young children's skin is exceptionally thin, delicate and lacks full melanin protection, meaning it burns much more quickly and painfully. Even if you are spending most of your time in the shade, every trip outside must include applying a proper layer of UV-protective sun cream. For children — and especially babies — the safest choice is a mineral sunscreen with SPF 50, which forms a physical barrier on the skin that reflects UV rays. Apply the product to all exposed areas of skin (including the face) and reapply every few hours, as well as after every session in the paddling pool or water play and after towel-drying.
Serve Light Meals
When the temperature outside is hitting record highs, it's perfectly normal for children's appetites to drop sharply and for them to refuse their usual portion sizes. Don't force your child to eat thick hot soups or heavy meats — instead, opt for cool, refreshing snacks packed with vitamins. Fresh fruits with a high water content work brilliantly — juicy watermelon, strawberries, blueberries or peaches — and for lunch, chilled gazpacho-style soups made with seasonal vegetables are a great option. Nutritious chia puddings and fruit smoothies also make excellent additions to a summer menu, providing small tummies with the energy they need while keeping them cool.
Organise Water Play
On hot days, water play is a parent's greatest ally — it brings children instant relief from the heat and loads of genuine fun. If you have a garden or a larger balcony, set up a small paddling pool filled with cool water in a shaded spot so your child can splash around safely under your supervision. When you are out and about or on a walk, a simple spray bottle filled with water makes a wonderfully refreshing, gentle mist for the skin.
