Russia: If you want to be healthy – "quench" yourself!

Note: "quenching oneself" is a specific Russian term that derives from the Soviet Union times and relates to special training of thermoregulatory processes in the body by regular exposure to cold temperatures. The technique is neither evidence based nor proven effective. My grandfather actually got pneumonia by "quenching himself."
