You can still use a paddling pool, but using a watering can or bucket to add water.
There are a few alternative ways to cool down in the hot weather, including:
Target key cooling points
Use small amounts of water on areas where blood flows close to the skin - wrists, back of neck, temples, inside elbows and behind knees.
These spots help to cool your whole body faster than soaking yourself.
Drip, don't drench. A few drops will go a long way.
You can also use anything that's cool, such as a shaded stone, on your pulse points for the same effect.
Efficient evaporative cooling
Lightly dampen a cloth, scarf - even your shirt or a t-shirt. Place it on your neck or head. Sit in a breeze or, if you have one handy, use a fan.
As water evaporates, it pulls heat away from your body.
Cool your extremities
If you have a small container to hand, dip hands or feet briefly in water, then let them air dry.
This uses less water than full-body splashing but still provides cooling.
If you still wish to use a paddling pool, please cover it overnight. When you've finished with it, the water can be used on your garden.
