The innovator of the technique in question is Doctor Sergei Bubnovskiy, a professor from Moscow. He claims that this simple method can boost and strengthen your immune system.
The professor recommends soaking your feet in chilly water and keeps them there for at least 10 seconds, right after you return from work. Applying this every day will strengthen the immune response and prepare you to combat flu and colds during the winter.
This claim is supported by an English study which states that having cold showers every day increases the number of white blood cells, which are in charge of fighting various viruses and infections.
The scientists from the Britain’s Thrombosis Research Institute found that as the body struggles to increase its temperature after an ice-cold shower, the metabolism also starts to work faster, thus triggering a response from the immune system and increasing the number of white blood cells.
Another study, this time a German one, suggest that swimming in cold water in winter on a regular basis enables the body to deal with oxidative stress. If you do this from time to time, it will only harm you because the cold swims causes this type of stress. But when deployed regularly, the body gets accustomed and the protective system becomes stronger.
How to Deploy the Cold Feet Bath
Fill a small bathtub with cold water and add ice (as much as you can find). Soak your feet in the tub and hold them there for at least 10 seconds. Repeat every night after work or before going to bed.
In case your immune system is very weak, soak your legs in cold water every four hours. You will notice the first results after a week or so.
