Oh no, not running hands under water. Yes it feels great at the time, but you risk serious chilblains, and they're not funny. Fingerless gloves are a great idea (I used to have a pair somewhere, when they were fashionable!)
The other way to get your hands warm - but don't do it if they're frozen from doing things like scraping ice from your windscreen with no gloves on! - is to shake them vigorously making your fingers really loose. It may feel too painful if your hands are really cold. Hot cups of tea/coffee/chocolate are good or rubbing, but again you need a lot of effort to maintain the rubbing to get the circulation going.
