It's hard to say for sure - most of the claims are anecdotal. For instance, some people say that you're less likely to catch a cold; however, the counter-argument is that people who are prone to catching colds won't continue with regular exposure to cold water. So, this may just be correlation rather than causality.
I saw a poster at the lido a couple of months ago, looking for volunteers to take part in a research study; I think the idea was to look at couples where one person swims and the other doesn't, so that the rest of their lifestyles will be as similar as possible. I assume that this study will run through the winter, and the researcher might publish some results next year.
