Summer this year seems to have come early, and as we enjoy the long days and sunshine, heatwaves can sneak up and catch us off guard. While we all love a good bit of warm weather, it’s important to keep children safe and comfortable when temperatures rise. Little ones are more at risk during extreme heat, but with a few simple steps you can ensure they stay  safe, cool and hydrated while creating lovely summer memories.

Spotting the Signs Early

Children can easily get caught up in play and might not notice when they’re getting too hot, so it’s important for adults to keep an eye out for any signs of heat-related illness.

Watch out for:

• Tiredness or weakness

• Headaches or feeling faint

• Muscle cramps or feeling/being sick

• Heavy sweating and intense thirst

These signs below suggest heat exhaustion, which can usually be managed quickly with some simple steps. If it isn’t addressed, though, it could develop into heatstroke, so it’s best to take action as soon as you spot anything unusual.

• Confusion or lack of coordination

• Rapid breathing or heartbeat

• Hot skin that’s not sweating

• Seizures

If you notice any of these, quickly move the child into the shade, cool them down with water and wet flannels, and call 999 in an emergency.

Plan Ahead

Check the weather forecast and be ready when high temperatures are on the way. Try to schedule outdoor fun like picnics or playtime early in the morning or later in the evening when it’s cooler. Avoid being out during the hottest part of the day, usually between 11am and 3pm.

Keep Your Home Cool and Comfy

Your home should be a cool escape from the heat. Here’s a few ideas to make it more comfortable:

• Draw the curtains or blinds during the day to block direct sunlight

• Open windows in the evening or early morning when it’s cooler outside (if safe to do so)

• Switch off appliances and lights not in use – they generate unnecessary heat

• Use electric fans if it’s under 35°C – but don’t point them directly at anyone, as it may cause dehydration

Don’t Forget the Suncream

While we’re all chasing the sunshine, protecting the skin is a must. Children’s skin is especially sensitive, and too much sun can cause damage even on cloudy days.

How to stay sun-safe:

• Choose a broad-spectrum sunscreen with at least SPF 30 and good UVA protection (look for a 4 or 5-star rating).

• Apply it generously to all exposed skin — including easy-to-miss spots like ears, necks, tops of feet and backs of knees.

• Reapply every couple of hours, and always after swimming or towel-drying.

• Try to apply it 15–30 minutes before going outdoors, so it has time to absorb properly.

• For babies under 6 months, it’s best to keep them in the shade and out of direct sunlight altogether.

Dress Light, Keep Bright

What you wear makes a big difference in how heat affects you. Dress little ones in loose, light-coloured clothing made from breathable fabrics like cotton. A wide-brimmed hat and sunglasses with UV protection will help shield them from the sun while out and about. UVA fabrics are also a great way to keep children protected, especially those who find the application of sunscreen challenging.

Drink Up!

Hydration is key. Make sure children drink fresh water regularly – don’t wait until they say they’re thirsty. A reusable water bottle can help encourage regular sips throughout the day. Ice lollies and juicy fruits like watermelon are also great, refreshing treats!

Check In on Each Other

If you’re a parent, carer, or grandparent, keep in touch with others — especially friends and neighbours who might also be caring for little ones. A friendly chat can be a lifesaver (and a good excuse for a cuppa indoors with the fan on!).

Be Heatwise, Not Heatworried

While heatwaves can be serious, a bit of forward planning and awareness goes a long way. Keeping children safe in hot weather doesn’t mean they have to miss out on the joys of summer. With cool drinks, shaded play, and time to rest indoors, you can make the most of the sunny season safely.
