Why Americans take their shirt off when running?

Americans believe in science.

The human body cools off through perspiration.

Perspiration doesn't work very well when your skin is covered up.

They don't.

Just look at you.

What science don't I believe in?

Shush Europoor

Because Americans like their nipples titillated by the cool breeze while running, but Europeans are too prudish.

Euros come to America to Free The Nipple!

Americans love skin cancer. Also, despite studies showing wicking tops provide better cooling they love bro science.

Europeans (especially nordic peoples) are slaves to social custom and hyperconformist (just step inside an ikea). I’ve never questioned running without a shirt on — if it feels more comfortable I do it.

Under what mindset would someone question it? Does anyone really care this much about what “other people” might think of them? The one valid reason against it that I’ve heard was when my friend put his shirt on as we got close to campus because his “girlfriend would be mad if a student saw him without a shirt on and thought he was hot”. This is an exception that proves the rule (being, running shirtless is the best).

My high school coach once got mildly angry because so many kids were wearing compression shorts that stuck out from under their split shorts. It’s basically the same thing - what purpose does it serve to do that? what is the effect of not wearing a shirt or long compression under your shorts? it’s nothing. People only do this because of idiotic social pressure.

So your "scientific" contention is that humans were not meant to be in sunlight and that "studies" show that sweating into cloth on top of your skin provides more cooling than letting your skin itself sweat into the breeze. Because you're not a "bro"?

Can you provide any of these studies?

But you guys were thong bikini at the beach. I find that more gross.

I have to live like my hero (Borat)

You consider that a valid reason to put a shirt on?

Wrong, I often do and I’m European.

I'd say doing something to please the person your in a relationship is more valid than not doing something because of what strangers might think.

Studies also show that fabrics are a breading ground for bacteria and that wearing sweaty garments can be bad for your skin.

If you do not have a job where you work outside and are exposed to sun all day, running a without a shirt during the summer is really not that great a risk for skin cancer.

I'm pretty sure "metric system" is in an orange vest laying in the road blocking a highway by now. He probably thinks there are "studies" that show cars idling on a highway for 2 hours rather than driving for 20 minutes emit less CO2.

He won't be defending his absurd claims.

In Europe people freak out when it hits 90. The United States is further south, 90 degree temperatures are pretty common, 80 is very common. Generally people are going to run without their shirts if it's 75+, the alternative is sweat your @$$ off.

I just looked up London's average weather by month. The hottest month, July, the average high is 74... Ya no need to take your shirt of 99% of the year for you.

‘Wicking’ is no longer valid when the shirt is completely soaked in sweat. All it’s doing at that point is weighing me down, chafing parts of my body, and giving me one more thing to hang to dry then wash.

I'm not convinced it's ever valid. Wicking is better than a shirt that just absorbs the sweat but I fail to see how it could improve perspiration. I think there's a reason no one has linked these "studies".
