I started a thread a few weeks ago about how my bike gloves get disgustingly smelly. I've decided I'll wash them frequently now, every day, if possible. Same with my helmet. I may have to have two pairs of gloves and two helmets and alternate them.

I'm pretty thin so I don't sweat for long after I exert myself. I can shorten the time even further if I wash my face, head, and neck upon arrival at work. The water cools me which cools my blood, which cools my body. Washing clears my pores, allowing me (and my pores?) to breath more easily.

I suppose it is easier to ride gently on an upright bike. I ride Citi Bike (the NYC bike share) at least once a week. Those klunkers put the rider very upright. Now that I think of it, yup, I don't sweat as much on those bikes as I do on my bikes. Not that I want my bike to have upright bars.

Air conditioned subway cars came in the 1980s if I remember right. It made the overall subway riding experience better, but the downside is that the station platforms are intensely hot. The trains spew a lot of heat, and that heats the tunnels as well as the stations. The platforms are hot for weeks after the summer heat is gone because the bedrock retains the heat so well.
