I've always wondered about the whole cold lowering your immune system thing. On one hand, I've read that studies have shown this to be the case, but on the other hand, doesn't subjecting your body to moderate levels of hormetic stress actually make you more resilient? It seems like there should be a noticeable increase in sickness among people who take cold showers if this were true, the opposite of what they tend to report.
