Does this actually work, or are we just asking for medical trouble by starting some "therapy" like this? I’ve read—and seen clips on the news—about these winter swimmers who supposedly stay immune to the common cold and the flu. They even claim these people don't even need to turn on the heat in their houses during the winter. Apparently, you can get a similar kind of physical conditioning through daily contrast showers—alternating between hot and cold water. Has anyone here actually tried this?
