Constantly suffering from colds is a reason enough to strengthen your immune system, and professor Sergei Bubnovskiy from Moscow has an innovating new technique that can do it.
According to the professor, soaking your legs in an ice-cold bath for 10-15 seconds after coming home from work can reinforce your immune system and prepare it for the fight against colds and the flu!
Pour cold water in a bathtub or basin, then add as much ice as you can get and soak your feet in the tub for 10-15 seconds. Repeating this method every night before going to bed will improve your immune system quickly. The method is especially beneficial for people with weak immune system – in this case, soak your feet in icy water every 4 hours.
