Swollen legs: this helps against water retention

Heavy legs, swollen feet: water retention can be a nuisance. But where does the pent-up water in the body come from? And what can you do about it?

It’s hot – and suddenly your legs swell up. The calves, the ankles: painfully swollen, the socks or sandals cut. The edema is colloquially called “water in the legs.” Sometimes the water retention disappears when you leave the office and exercise – but sometimes your legs remain swollen.
