1. Eliminating stress

Stress is a reaction of our body to a dangerous or complex situation. As part of the fight-or-flight response, the adrenal glands release cortisol (also known as the stress hormone). And according to this study, cortisol increases fluid retention. If you want to forget about puffiness and stiff joints, practice breathing techniques, leg lifting, yoga, and learn to relax properly.
2. Relaxing in the sauna
A sauna is not only a good way to relax and escape from your everyday problems, it’s another way to decrease water retention. According to an article published by Harvard Medical School, sweating begins almost immediately. An average person loses a pint of sweat during a brief stay in a sauna.
