Thats just the way the human body is though. The extremes get colder quicker, as they are further from the core. Plus they dont generate so much heat. So its double trouble.
On a bike your feet and hands are right in the path of the cold air, youre pushing yourself through. Probably both attached to metal heat sinks. Neither being used much to promote circulation.
Its a shite situation if you look at it. The only answer is not to let these extremetie lose heat to start with.
Yep, pretty much hit the nail in the head here.
