Sweat

ok, when i do my cardio sessions i usally do them with no t-shirt on to prevent myself from getting too hot. This got me thinking, if i do them with a t-shirt on i will be hotter and will sweat more because of that. Does the extra sweat mean that i am burning more energy? Or does it just mean that i am getting dehydrated quicker? If it does mean more energy is getting burnt, how much more? Thanks people

you're just getting dehydrated more quickly.

if you want to use thermogenics, exercise in an air-conditioned room, during cold weather, or with a fan blowing right on you. your body then has to work harder to keep your temperature up.

Sweating is NOT a function of how hard the body is working. I rarely sweat but my body heats up nicely. I used a heart rate monitor for a year and now I know when I'm at the right level based on how my body heats up.

Like 3Norns said - Keeping your shirt on will cause you to dehydrate more so make sure you are drinking plenty of water. It will also contain the body heat more so it is important to not overheat.

If sweating was a sign of burning more calories then I'd be the first to get one of those silly (and dangerously moronic) thermal suits.

ok, thanks guys. i should have posted this yesterday because i did a 40 min cardio session with my t-shirt on which caused me to sweat like mad. In fact every 5 seconds a drop of sweat would hit the floor. Anyways, i tried to drink as much water before, after and durning my workout. But today i feel like ****, i hurt everywhere and everything feels tender. I am thinking this is a result of my stupidity. Thanks again guys, next time the shirt will be off.

I know some that prefer the shirt on, if they are exercising outdoors. Especially a cotton shirt. The shirt traps the sweat (keeps it from evaporating to quickly), and can help keep the body cooler.

Don't know for sure how sound this logic is, but it seems to make sense.

sorry, that's backward: the sweat evaporating is what cools the skin. by keeping the shirt on, the wet fabric traps heat against the body making you sweat even more.

The shirt will also keep cool as the wind/air hits it. Ever put a sweaty shirt back on after you've taken it off?

Just pointing that the sweat evaporates more slowly from the shirt than the skin, offering a natural air conditioner for much longer.

There's also the "shiver effect."

Aggred Mrs C,

kd, get yourself a heart rate monitor.

yer i got one on me bike. I have still been doing most of my cardio in a hot shed (with shirt now off) and have been pushing hard. Yesterdai i went running outside in quite hot wether but not as hot as in my shed. I was flying during the run, probably the quickest 8 miles i have ever run. I think this is down the heat that i was training in before. My body must be used to working extra hard to keep me cool that it felt as though a weight had been lifted, making my run easier.
