So dressing more warmly after the ride doesn't solve this problem.
Something fundamentally wrong happened to my body during the ride, even though I didn't feel it at the time. Interesting. Maybe its not the ride, its your body. The cooler temps while riding might have triggered this episode. |

That's the most critical thing to staying warm after working out -- being dry. JT **************************** Remove "remove" to reply Visit http://www.jt10000.com **************************** |

Note that your body is typically only 20 to 25% efficient producing power to the pedals. This means that if you put out 200 watts then you also produce 600 to 800 watts of heat. When you get off the bike you likely reduce that heat output and thus you should either go inside or put on warmer clothes.

Something fundamentally wrong happened to my body during the ride, even though I didn't feel it at the time. Check out these sites: http://www.bikewinter.org/bikewinter...keclothing.php http://www.joeclark.org/gearingup.html http://users.rcn.com/icebike/Clothing/clothing.htm Most are oriented toward commuting or Mountain Biking. But if it's for fitness, don't worry about aerodynamics! I think you're correct that food is an issue. If you are dressed with light clothing, youre body needs to spend some of the food energy on heat generation. Usually this is not a problem when exercising, but it can be. So, by the end of the ride, you already were hypothermic. You just didn't feel it until you slowed down, and it took a while for your internal temperature to catch up on NO energy. I've seen two mildly hypothermic people recover in about fifteen minutes after feeding them something healthy and forcing them to drink properly. Incidentally, shivering is good - it means you still have enough energy to move your muscles, and your nervous system can properly detect temperature imbalances. When you stop shivering but are still cold, it's time to get attention immediately. Also note that dehydration inhibits proper temperature regulation as well. It's easy to become dehydrated in winter only because the need for water is less apparent and people drink less. Your body still loses moisture through breath and perspiration. |
