In the summer, is it better to run with a shirt on or without? I guess what I'm trying to ask is does your body cool down faster with a shirt off?

For temperature regulation (cooling), shirt on if it's sunny (light color & keep it damp); shirt off if it's cloudy.
I would love to see someone present actual evidence of this.
Also consider the potential damage the sun can do to your skin....man, I am getting old.

And consider the damage to the rest of your body if you hardly ever get any UV rays at all(UV rays promote your body to produce vitamin D, which may help against just about all other types of cancers)
The Fear of skin cancer is real for some people, but has been waaaaaaay overblown to the detriment of many others. In short more people have likely suffered than been "saved" because the national programs to get everyone to cover up 24-7, avoid the sun at all costs, and wear 100 spf sunblock all the time.
No shirt, especially if you are Jessica Simpson or Lindsey
Lohan.
OK, there I took this thread down to it's lowest level.
As far as guys are concerned it's personal preference, but when blackfly and deerfly season comes around it's not a GOOD idea.
I live in New Jersey and it all depends where I am running. If I'm at a park or down the shore, no shirt. If I am at home running, I wear a shirt because I feel like an idiot running with no shirt waving to my neighbors.
I run without a shirt, and also at morning and dusk so skin damage is avoided.
No shirt = less laundry to do.
why is it, that as a distance runner you can spend hours a day in the sun without a shirt on and not get a tan? you get the little watch line, but no real tan!
and don't tell me it's because you're faster than the sun...
Simple enough to me: when its hot enough that a shirt makes me overheat, shirtless. Usually anything over 65 degrees and the shirt is off.
the magic potion of love is in the air.
i never wear a shirt, even in winter.
live long and prosper.
out.

I've wondered the same thing. Could it be because the sweat reflects a significant portion of the sunlight? I get burned very easily when i'm out in the sun, but i've never gotten burned on a run (i've been running for 9 years, and I often run shirtless in the summer).
It could also be because i'm often on trails in the shade, but that's not always true.
You never see the Kenyans running with no shirt
That's because Kenyans have no nipples. Think about it, why else wouldn't they?
They are trying to "lose weight" by sweating away the water in their bodies. That's what one of them told me anyway.

I'm thinking powerpoint.
Without a shirt is obviously cooler. Think of it this way -if you are warmer when it is 30 degrees with a shirt, why would you be cooler with a shirt at 90 degrees? It holds in your body heat (and makes sweat less efficient) no matter the temperature.
I did a science research paper on this topic. The answer is yes and no. When it is 32 degrees Celcius measuring scale of temperature externally then according to my calculations it would benefit you the most if you had a mix of no shirt and a shirt.
