How to Keep Children Safe in Hot Weather ☀️💦

As temperatures soared this week, our children found some wonderfully creative ways to keep cool while continuing to learn, explore and have fun.
The garden quickly became a hub of water, ice and scientific discovery. Armed with giant syringes and water guns, the children aimed streams of water at targets on the wall (and occasionally at each other during some very enthusiastic water fights!).
Others were fascinated by our water wheels, carefully pouring water into funnels and watching with delight as the trickling water set the wheels spinning.
One of the week's favourite activities involved rescuing toy elephants trapped inside blocks of ice. Using small toy hammers, the children chipped away patiently, experimenting with different techniques and celebrating each successful rescue. Nearby, young anglers tested their coordination and concentration by trying to catch toy fish with nets.
While these activities provided plenty of laughter and excitement, they also offered something very important during hot weather: a chance to stay cool safely.
Why Are Young Children More Vulnerable to Hot Weather?
According to NHS guidance, babies and young children are more susceptible to overheating and dehydration than adults.
Their bodies are still developing the ability to regulate temperature efficiently. Young children have a larger body surface area relative to their size, can lose fluids more quickly, and may not always recognise when they are becoming too hot or thirsty. Babies are particularly vulnerable because they rely entirely on adults to help manage their environment, clothing and fluid intake.
This is why hot weather requires a little extra care and attention.
Spotting the Signs of Overheating
Most children will naturally slow down, seek shade or ask for a drink when they feel warm. However, it is important for adults to recognise the early signs that a child may be becoming overheated.
Some common signs include:
Flushed cheeks
Excessive sweating
Unusual tiredness
Irritability or fussiness
Dizziness
Headache (in older children)
Feeling sick
Reduced appetite
Signs of dehydration can include a dry mouth, fewer wet nappies, dark urine, sunken eyes or lethargy.
If a child becomes unusually drowsy, confused, unresponsive, develops a very high temperature or shows signs of heatstroke, urgent medical advice should be sought immediately.
Simple Ways to Keep Children Safe in Hot Weather
The NHS provides practical guidance for families on staying safe during periods of hot weather. Parents can read the full advice here:
Offering regular drinks throughout the day is one of the most effective ways to prevent dehydration. Young children often become so absorbed in their play that they forget to ask for a drink, so gentle reminders can be helpful.
Lightweight, loose-fitting clothing made from breathable fabrics can help keep children comfortable, while wide-brimmed hats offer additional protection from direct sunlight.
Whenever possible, outdoor activities should take place in shaded areas, particularly during the hottest parts of the day. At Fun Box, we carefully monitor temperatures, provide plenty of opportunities for water play, encourage regular drinks and make use of shaded areas in the garden.
Activities involving water and ice are not only enjoyable but also support children's wellbeing. Water play helps children cool down physically while also encouraging scientific thinking, problem-solving, hand-eye coordination and sensory exploration. As children pour, splash, investigate and experiment, they begin to explore concepts such as cause and effect, gravity, flow and movement.
Don't Forget Sun Protection
Keeping children cool is only one part of staying safe in hot weather. Protecting their skin from harmful UV rays is equally important. We recently shared a detailed guide for parents about choosing and using sunscreen safely with babies and young children. If you missed it, you can read it here:

For families who would like to learn more about keeping babies and children safe during hot weather, the NHS provides additional guidance on recognising and preventing dehydration:
These resources contain practical advice about fluid intake, recognising warning signs and knowing when to seek medical support.
Making the Most of Summer Safely
Hot weather can provide wonderful opportunities for learning, exploration and outdoor play when sensible precautions are taken.
This week's water wheels, ice rescues, fishing games and water fights reminded us that some of the best learning experiences are often the simplest. By combining plenty of fluids, shade, sun protection and cooling activities, children can continue to enjoy all the benefits of outdoor play while staying comfortable and safe.
After all, summer is meant to be enjoyed—and sometimes all it takes is a little water, a block of ice and a lot of imagination. ☀️💦🧊
