How to stay safe swimming outdoors - and still have fun

Many bodies of water in the UK remain under 15C (59F) all year round, meaning they are "dangerously cold", says Hickman. Getting into cold water too quickly can cause cold water shock, which restricts your ability to move and affects your breathing. There is a risk of drowning if you inhale water. You are most likely to get cold water shock if you jump into the water. Instead, you should get in slowly and allow your body to acclimatise. Oakley-Jenner says his mantra is "ankles, hips and nips", which reminds him to slowly lower each part of his body into the water until he gets used to the temperature. If you do notice signs of cold water shock, you should try to regulate your breathing and float on your back . Pennicard advises people should practise floating in swimming pools. In an emergency, make sure you keep your head back, your ears in the water, and calm your breathing before making any decisions. Jake Butt, lead lifeboat supervisor at the RNLI, says you should shout for attention and wave to show your location - but only use one hand, so you can use the other to help you stay afloat.
