🌡️ Walking safely in a heatwave
Preparation, common sense, and knowing when to stop.
Before you go
🗺️
Plan a shorter, shadier route
Woodland is ideal. Know your bail-out points in advance — where can you cut the walk short if needed?
💧
Hydrate before you leave
Start drinking water well in advance, not just as you head out. Water-rich foods (cucumber, melon, oranges) help too.
⏰
Time it well
Head out early, before peak heat (usually 11am–3pm). If going later, know when sunset is — don’t get caught in the dark.
👥
Tell someone your plan
Go with a friend, or let someone know your route and agree a check-in time for when you’re back.
What to wear and carry
👕
Light, loose clothing
Light colours reflect heat; loose fits allow air to circulate. Avoid dark or tight synthetic fabrics.
🕶️
Hat, sunglasses, sunscreen
Wide-brim hat for shade, UV-rated sunglasses, and SPF 30+ sunscreen — reapply every 2 hours if sweating.
🥤
More water than you think
Carry more than usual. Sip regularly — don’t wait until you’re thirsty. Thirst is already a sign of dehydration.
🎩
The wet hat trick
Douse your hat with water before putting it on — surprisingly effective. Just be mindful of using drinking water for this.
On the walk
🌳
Rest in shade regularly
Take breaks before you feel you need one, not after. Don’t push through discomfort.
⚠️
When in doubt, turn back
If it’s extreme heat or you’re not feeling right, postpone. No walk is worth a medical emergency.
Know the signs — medical
⚠️ Heat exhaustion
Can precede heat stroke if untreated
- Headache, dizziness, confusion
- Nausea, loss of appetite
- Heavy sweating, pale and clammy skin
- Intense thirst

Move to shade and rest immediately. Cool the skin with wet clothing or a damp buff on the back of the neck. Drink water steadily. End the walk.
🚨 Heat stroke
Medical emergency — call 999
- Confusion, slurred speech, delirium
- Nausea or vomiting
- Hot and dry skin (not sweating)

Call 999 immediately. Keep cooling the person while waiting. Lie them down. If unconscious, place in the recovery position and monitor continuously.
