Adapting to the heat

[shootingstar]

I keep reading that when temperature in Fahrenheit plus percentage humidity is greater than 150, one shouldn't exercise. I don't really believe that either and I certainly don't practice it, but I'm not really sure it's safe to go out without any adaptation at all.

150% humidity....ugh.

When living in humid summer areas, I used to try to start cycling off no later than 7:00 am. Earlier if possible. I never did understand why more people didn't start biking around 6:30 am on those days on weekends. I lived near and used several bike routes that were well-known in Toronto. At that time, the car traffic would be lower also.

And finish the ride around 9-10 am.
I'm a morning person anyway, so it wasn't a painful thing to start off early.

However, I have done loaded bike touring trips on summer days at 90F @ 100%. By noon, I was gettin' wasted...but sometimes there's no choice but to press onward in order to find a place to sleep and eat supper. It helped pyschologically if there was a slight breeze and some trees lining the route at various intervals along the way.
