How to Stay Cool in Summer: The Ultimate Guide for UK Families from Babies to Grandparents

Ah, British summer. That magical time of year when the sun graces us for longer than 17 minutes, ice cream vans play their haunting tunes, and we all collectively remember that our houses were designed to trap heat, not get rid of it.

The UK isn’t exactly famous for its scorching summers, but when they arrive, we panic-buy fans, strip off layers we’ve been wearing since October, and start Googling “how to sleep in heat without losing your sanity.”

This guide is for everyone — from the tiniest new human in a sunhat to the wise grandparent sipping tea in the shade — packed with practical advice, funny truths, and enough tips to get you through a heatwave without melting into the sofa.


Understanding Why the UK Gets So Unbearable in Summer

If you’ve ever wondered why 28°C in the UK feels like 40°C in Spain, here’s the science:

  • Humidity: Our air likes to hold on to water like it’s in a clingy relationship.

  • Buildings: UK homes are insulated to keep us warm in winter… and in summer… and in September.

  • Our attitude: We spend most of the year moaning about the rain and then, when the sun arrives, we “make the most of it” until we’re sunburnt and dizzy.

So yes, we are slightly to blame. But don’t worry — we’ll fix that with some sensible (and some slightly silly) tips.


Keeping Babies Cool

Babies are basically tiny hot water bottles that can’t regulate their temperature well. Here’s how to help them:

1. Light Clothing

Stick to loose, breathable fabrics like cotton. If it’s really warm indoors, a nappy and a thin vest will do.

2. Shade is Non-Negotiable

Pram covers might look shady, but they can trap heat. Use a parasol or a specially designed breathable sunshade.

3. Cool Baths

A lukewarm (not cold) bath before bedtime can help them settle. Plus, splashing is fun.

4. Hydration

For babies under six months, extra breastfeeds or bottle feeds are enough. Older babies can sip cooled boiled water.


Tips for Toddlers and Young Children

Children have the magical ability to run around in 30°C heat like it’s nothing, but their little bodies can overheat fast.

1. Frozen Fruit Snacks

Frozen grapes (cut up to avoid choking), melon cubes, or banana slices make great cooling treats.

2. Paddling Pool Time

Best deployed in a shaded spot, unless you enjoy turning your kids into tiny lobsters.

3. DIY Water Play

Buckets, jugs, and plastic cups can keep them busy for ages. Bonus points for “car washes” with toy cars.

4. Cool Down Naps

Darken their room during the day with blackout blinds and keep a fan running — but not blowing directly at them.


Cooling Tips for Teenagers

Teenagers are complex creatures — prone to ignoring advice, rolling eyes, and wearing black hoodies even in a heatwave.

1. The Hoodie Ban

Explain that wearing thick layers in the heat is a one-way ticket to feeling faint.

2. Cold Showers

Perfect for freshening up and cooling down after sports.

3. Cool Hangouts

Encourage them to spend time in shaded parks or air-conditioned libraries instead of roasting in their bedrooms.

4. Hydration by Stealth

Teenagers love iced coffee. You can sneak in hydration by making iced herbal teas or diluted juice and calling it a “mocktail.”


Adults — Staying Cool Without Losing Your Dignity

We adults think we can tough it out, but the sweaty reality says otherwise.

1. Master the Cross-Breeze

Open windows on opposite sides of your home to let air flow through.

2. Cool Your Pulse Points

Dab cold water or press an ice pack against your wrists, neck, or behind your knees.

3. Light Meals

Heavy roasts and pies are lovely… in December. Summer calls for salads, cold pasta dishes, and fruit platters.

4. Dress for the Weather

Light fabrics, wide-brimmed hats, and sunglasses are not just fashion choices — they’re survival gear.


Keeping Grandparents Comfortable

Older adults can struggle more in the heat because their bodies don’t regulate temperature as efficiently.

1. Check In Often

Make sure they’re drinking enough water and staying in the shade.

2. Keep Rooms Cool

Close curtains during the hottest part of the day and use a fan to circulate air.

3. Simple Cooling Aids

Cooling scarves or gel pads can make a big difference.

4. Watch for Signs of Heat Exhaustion

Dizziness, headaches, or nausea mean it’s time to cool down fast.


Pets Are Family Too

Dogs, cats, and other furry friends can suffer in the heat.

  • Walk dogs early morning or late evening.

  • Keep fresh water available at all times.

  • Avoid leaving pets in cars, ever.


Home Cooling Hacks

  1. DIY Aircon: Put a bowl of ice in front of a fan. Instant arctic breeze.

  2. Sheet Swap: Switch to cotton or linen bedding in summer.

  3. Window Wisdom: Keep windows closed during the hottest hours, then open them in the evening.

  4. Reflective Foil: A temporary foil covering on south-facing windows can block heat.


Fun Ways to Stay Cool Outdoors

  • Go to the beach (bonus: the sea is like a giant ice bath in the UK).

  • Visit shaded gardens or woodland trails.

  • Take a picnic with cold foods and frozen drinks.


Sleep Like a Polar Bear

1. Cool Bedding

Choose breathable fabrics and skip the heavy duvet. I love the Bedsure Cooling Blanket. I have been using this every night over the summer and it is honestly like a cheat code for a great nights sleep!

2. Bedside Ice Pack

Wrap one in a tea towel and pop it near your feet.

3. Pre-Cool the Room

Fan + open window = better bedtime.


Recognising Heat-Related Illnesses

If someone shows signs of:

  • Headache

  • Confusion

  • Heavy sweating or no sweating

  • Rapid heartbeat
    … it’s time to get them somewhere cool, give fluids, and seek medical help if symptoms worsen.


The UK might only get a few weeks of real heat each year, but when it happens, it’s intense. With the right mix of humour, planning, and maybe a few sacrificial bags of frozen peas, you can keep everyone — from baby to great-grandparent — comfortable and safe.

And remember: sunburn fades, but the embarrassing photo of you lying face-down on a paddling pool will last forever.
