A popular Moscow professor, Sergei Bubnovskiy has revealed his innovative method to boost the immune system.
According to Sergei, soaking your legs in an ice cold bath for 10–15 seconds as soon as you return home from work can strengthen your immune system and help you combat the common cold.
A study also found that taking daily showers with cold water can increase the numbers of disease-fighting white blood cells.
The study found that as the body tries to warm itself during and after showering with cold water, the metabolic rate is accelerated and the immune system is activated, and thus causes the increased number of white blood cells.
So, if you want to boost your immune system, pour some cold water in a basin or in the bathtub. Add as much ice cubes as you can and soak your feet for 10–15 seconds. Repeat this every night and you will strengthen your immune system fast. If you suffer from weak immunity, soak your feet in ice water every 4 hours.
