He maintains that soaking the legs in an ice-cold bath for 10-15 seconds as soon as you return home after work can strengthen the immune system and help it combat common colds and flu!
Another English study showed that the daily showers with cold water increase the numbers of disease-fighting white blood cells.
Namely, the team of researchers at the Britain’s Thrombosis Research Institute found that as the body attempts to warm itself during and after the 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.
Another German study showed that the occasional winter swim in cold water leads to oxidative stress. Yet, if this becomes a regular routine, it causes an adaptive antioxidant response and the body is able to fight oxidative stress even better as soon as it gets used to cold-water swims.
This is what to do to boost your immune system:
You should pour some cold water in a basin or in the bathtub. Then, add as much ice cubes as you can, and soak the feet in it for 10-15 seconds.
You should repeat this technique every night at bedtime, and you will strengthen the immune system fast. It is extremely useful in the case of weak immunity, and those people should soak their feet in the icy water on every 4 hours.
