None that I know of besides avoidance.
Why? Freeze some bits? Or just feeling a chill around here? :-)
If you froze any of your body parts, see a doctor. And be prepared to suffer the cold forever after, as frostbit parts will be suceptible to cold, pretty much forever after.
Infections and gangrene are real risks.
This is my weather.30 below, and blowing.
Time to crawl back under a warm blanket.
