You probably think that this is impossible, but Russian doctor Sergey Bubnovsky claims that he found one of the most successful methods to enhance immunity, it is necessary to allocate 15 seconds of your time per day.
If you have a weak immune system, you often suffer from colds and flu or you are tortured by allergies, try this incredibly easy trick.
Fill the basin with cold water and add some ice. Place your feet in a basin for 15 seconds, then wipe with a towel and put on wool socks.
Dr. Bubnovsky claims that if you practice this every day, your immune system will begin to strengthen, and eventually all diseases will be powerless against you. He also says that you should not be afraid to catch a cold during this procedure, because everything happens on the contrary — it will only strengthen the immune system.
