Heatwave: Tips to Keep Your Child with Sickle Cell Safe

Hello Reader,

The UK is experiencing another heatwave, with temperatures climbing into the 30s°C and an amber heat-health alert in place across England.

While many people see sunshine as a chance to enjoy the outdoors, families living with sickle cell know that extreme heat can bring real health risks.

That's why we've put together this special edition to help you understand why heat matters, what practical steps you can take, and when it's time to seek urgent medical care.

We hope you'll also share this with another family who may need it.

Why Heat Can Trigger a Sickle Cell Crisis.

When the weather gets hotter, your child's body loses more water through sweating. If that lost fluid isn't replaced, dehydration can happen more quickly than you might expect.

Here's why that matters for children living with sickle cell:

☀️ Heat increases the risk of dehydration.

⬇️

💧 Dehydration means there's less fluid in the bloodstream, making the blood thicker and slower to flow.

⬇️

🩸 Thicker blood makes it easier for sickle-shaped red blood cells to stick together and block small blood vessels.

⬇️

⚠️ Blocked blood flow can reduce the amount of oxygen reaching different parts of the body, triggering a painful sickle cell crisis.

This is why staying cool and well-hydrated isn't just about comfort during a heatwave. it's one of the most important ways to help reduce the risk of a pain crisis.

💡Remember: In hot weather, prevention is always better than treatment. Small, regular sips of water and staying cool can make a big difference.

Know the Red Flags.

Imagine your child has been playing outside all afternoon. By evening they're unusually tired and complaining of a headache. Is it just the heat or could it be the start of a pain crisis?

These early signs can look very similar. That's why recognizing symptoms early and acting quickly is so important.

Contact your sickle cell team, NHS 111, or go to A&E / call 999 if your child has any of the following:

Pain that isn't easing with their usual pain relief
A temperature of 38°C or above
Confusion, extreme drowsiness, or difficulty waking
Fast or difficult breathing
No improvement after 30 minutes of rest, shade and fluids

When in doubt, don't wait it out — get them checked.

Keeping Your Home Cool

✔ Close curtains during the day

✔ Open windows once it's cooler outside

✔ Choose one "cool room"

✔ Avoid using the oven

✔ Switch off unused electronics

Keeping Your Child Hydrated

✔ Offer water regularly

✔ Little and often

✔ Avoid caffeinated drinks

✔ Carry a water bottle

Staying Cool

✔ Loose cotton clothing

✔ Cool flannel

✔ Cool shower before bed

✔ Avoid outdoor activity between 11am–3pm

Cooling on a Budget

You don't need an air conditioner to get through this. A few free or nearly-free options:

Ice-bowl fan trick: put a bowl of ice or frozen bottles in front of a regular fan — it turns warm air into a genuinely cool breeze for pennies.
Damp sheet over the window: a cold, damp sheet or towel hung over an open window cools the air as it passes through.
Damp flannels in the fridge: keep a couple on standby for quick cooling on the skin.
Know the running costs: a standard electric fan costs roughly £5–6 a week running nine hours a night; a portable air-con unit is closer to £15+ a week. If money's tight, the fan-and-ice combo gets you most of the benefit for a fraction of the cost.
Cool showers/baths before bed help lower body temperature going into the night — no equipment needed at all.
