Obviously a hot drink will raise your body temperature simply through the intake of fluids of a higher temperature than that of the body. The caffeine in tea is rather low dose however there may be some effect as both caffeine induces sweating and increases metabolic rate. This paper (http://ovidsp.tx.ovid.com.libproxy.ucl.ac.uk/sp-3.4.1b/ovidweb.cgi?QS2=434f4e1a73d37e8c1c7f5031d0406d8c3d 503b2c0677b14ea5a786901f309b62bcf89e5b02be0d238d6b f5824c328af04dcde4dc0b94f7b63029d348c68225a2668d8f 277599dff1a49129e0a3c77f3a89b102371e1248878367eca3 bb97abc955031717da247ca3e6750cbf5ff7da93d096c66945 3fefeeb2e18fce7d23f5ee4502aa722fdcaec66c702e307d61 52a0f8a959d3f2f92046b84f6859e56daddf513fc83355c741 6c00859628fb0fe369974ed0eff6d3b27ec7a90e3770484ba3 2b96a20df321205bfb4f411266d6eeac1a268d82784d515a1e c0dc8fea4a3677513e14551273055d92f8aaddcb67b83b1b65 e2f6e1366648f2a11cbccfa116cb349c3c61eb90a977527900 eadaaaac7ae0f5af8c82a8eaa2f1f0d3e8c8d9c449379f90f9 e575f55ea19daecf0c852c1e1f827165c0dc60393357d75091 1b4c4f007becc461b82879f8ddd8b494166fa8) deals with some of the effects that caffeine has on exercise and outlines some modes of action. Personally I would be of the opinion that there will not be that much of an effect and the majority of the effect that does happen is simply due to drinking a hot drink will raise your temperature due to it's temperature.

Increases in perspiration and metabolism will be dealt with shortly like any alteration in homeostasis.

Although tea has a caffeine that opens up your arteries, how can you think that it can cool your body? How can a hot drink can cool your body?

that is the question that I ask. Has there been any studies, or specific measurement to validate or dismiss this question?
is there any data to support or refute this question...i have no thoughts one way or the other..hence..my post..

It could be possible if the drink contained an antipyretic (http://en.wikipedia.org/wiki/Antipyretic). IIRC some Chinese herbal teas are used to treat fever because they do contain drugs of this nature though I would question whether or not this was an unsubstantiated alternative medicine claim. So it's not a bad question, there is some merit to it.

EDIT: Just remembered that the over-the-counter medicine Lemsip (http://en.wikipedia.org/wiki/Lemsip) can be administered as a hot drink but also contains an antipyretic intended to reduce fever.
