π‘οΈ 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 β 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 11amβ3pm). If going later, know when sunset is β 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 β reapply every 2 hours if sweating.
More water than you think
Carry more than usual. Sip regularly β 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 β 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.
