Professor Dr. Sergey Bubnowsky known Moscow specialist for kinesitherapy, suggests trying a simple method that will help you strengthen your immunity.
Every night when you come home after a hard day, put in a tub or bath-tub 10-15 cm completely cold water. Do not add hot water! Enter barefoot in the tub and tap with your feet in cold water only 10-15 seconds!
After that get out of the bath-tub and wipe your feet with terry cloth and put on wool socks. Do it every night and you will strengthen immunity.
If you already have a cold that’s a reason more to strengthen immunity. In that case dab with bare feet in cold water every four hours. Without fear that you will endanger your condition, on the contrary this will strengthen immunity, recommends Dr. Sergei.
