Freeze my ass off post-ride! Does this happen to others?

5:50 AM. I drink a big tumbler of iced coffee and take off on my commute. Its 42* F and I am wearing shorts, long sleeve shirt and long-john top. Feels brisk and invigorating but no real problems with cold even from the beginning except my hands get a little cold because I don't wear gloves. When I do this ride I cannot help but get into balls-to-the-wall mode.

15 miles later @ 6:60 AM I am sitting outside the coffee shop waiting for them to open reading news feeds on my smart phone. Perfectly comfortable.

7:20 AM, after my hot cup of coffee I have a 1/4 mile ride to my shop. Whole body is trembling and teeth chattering with cold. 9:00 I have put on long pants and turned on the heaters in the shop and I am finally starting to feel warm.

65 years old, don't take blood pressure meds, statins or other poisons. Fairly fit, not scrawny not fat.

This is a regular pattern for me. Does anybody recognize it?

I am guessing it is post-workout blood pressure drop? I know if I take my blood pressure an hour after a hard session at the gym it drops from 125/82 typical to 104/65typical.

I don't think it has anything to do with blood pressure. Your blood pressure will drop if you are dehydrated so that explains why it's lower after a gym session.

You're likely cold in the morning because you sweat while riding and when you stop your wet clothes start to dry which sucks the heat out of your body. You don't notice it while riding because your body is generating a lot of excess heat.

This is the reason they give riders space blankets after some long rides. The space blanket slows evaporation and heat loss.

Very common and normal - see this related current thread:

As soon as you finish your exercise ride get into some dry, warm clothes so you retain more heat now that your muscles aren't working anymore and keeping up your core temperature.

I drink buttloads of water at the gym -- have to pee every 10 minutes afterwards.

This morning my clothes were not even damp given it was 42* outside, and I don't think I was sweaty, but nonethless I froze my ass off afterwards. I even changed from shorts to long pants (heavy levis) and I had on 3 layers up top.

Seems like some kind of metabolic slowdown post-ride, but I certainly don't claim to know that for a fact, let alone fully understand it.

Thank you. I never check out the roadie forum. This is less something I have to fix than something I was curious about. Can't really change clothes at the coffee shop -- maybe I should sprint the 1/4 mile to work, or even take a 1 mile detour balls-to-the wall!
