.... so you FEEL cooler but you are NOT cooler. Yes. So it's psychological.
No because it isn't in your mind. Your temperature does not fluctuate, but you do feel cooler. Like when you hold ice in your mouth. Your mouth does get cold. So will your stomach if you drink something cold and the cooler blood does circulate through your body. It's not enough to make a major effect on your core temperature, but it does help you feel cooler. If I drink hot coffee on a cold day and put my hand over my stomach, it feels warmer than, say, my legs. Drinking something hot may not save me from hypothermia, but it does take the chill off in a normal situation.[/QUOTE]
No dude... the effect lasts for seconds, literally. your body is DESIGNED to dissipate all that excess heat or cold. If you hold ice in your mouth and leave it there it will make your mouth cold, yes.. but how long does it take for it to warm back up? Seconds. And, again, that's an extreme case because your mouth is only the first step. Nothing, ever, will last cold so long in your stomach.
And your stomach will ALWAYS feel warmer than your legs, come on! Now, if you drink something ICE COLD will your stomach feel colder than your legs. No. Never. EVER.[/QUOTE]
I must be odd because my legs, except my feet, are usually as warm as the rest of my body. But at any rate, I think we're getting to the point of arguing semantics. The major point we do agree on: drinking something hot or cold does not change your core temperature.
