Why do I swell up in the heat? 5 ways to reduce heat oedema this summer

The words ‘Britain’ and ‘heatwave’ don’t often go together, but when they do the whole nation has a habit of going into meltdown – along with our Magnums.

With temperatures set to soar to 34 degrees this week, the chances of experiencing swollen feet, swollen ankles and, well, swollen everything are high. But don’t panic.

Swelling and puffiness of the skin in hot weather is incredibly common. Known as ‘heat oedema’, it’s caused by a build up of fluid in the body.

Blood vessels near the surface of your skin automatically widen as temperatures rise, as a way of keeping your body cool. This increased blood flow can cause clear fluid from your lymph system to leak into the surrounding tissues, causing the swelling.

Some people naturally have more leaky capillaries than others, and most people will find this leakiness tends to increase with age.

While it’s perfectly normal to have some swelling in the heat, especially in your legs or feet at the end of a long day, a large amount of fluid build-up or swelling for no reason could be a symptom of an underlying health condition – so always check with your doctor.
