☀️ Why do our feet and ankles swell in hot weather?
If your shoes suddenly feel tighter, or your toenails start digging in during the summer, you’re not imagining it!
When we are hot, our blood vessels widen to help cool us down. This allows fluid to leak into the surrounding tissues, and gravity pulls it down into the feet and ankles. Add to the mix dehydration from sweating, together with prolonged sitting or standing such as on a long car journey or flight, and the swelling can become even more noticeable.
There are a number of underlying health conditions that can contribute to oedema, but if it’s caused by the heat, it usually settles on its own. The best way to help yourself is to keep moving. Walk whenever you can, do ankle circles, wiggle your toes, stay well hydrated and put your feet up after a long day. Movement is one of the best ways to encourage healthy circulation.
It’s also a good reminder not to squeeze swollen feet into tight shoes. Choose footwear that gives your feet room to move, and when you’re home, spend some time barefoot (where it’s safe to do so) to let your feet work naturally.
If your swelling is sudden, affects only one leg, is painful, or is associated with redness or shortness of breath, seek medical advice promptly.
