I think any extreme cold or hot isn't going to be good for you. If its freezing outside your going to put warm cloths on but if its hott your gonna wear less. Try reversing that and your gonna end up sweating or freezing your butt off. So think of your body as the temp outside, if you run hot than your gonna want something cooler. If you run cold than loading up on "cold" tea isn't gonna warm you up, you'll feel worse. What happens when your already full but you decide to keep eating?
"Warm (Hot) and Cool (Cold) are the very important principle in the Traditional Chinese Medicine (TCM). Chinese doctors employ these factors in the teas. White, Green or Jasmine Teas are considered cooling teas and often enjoyed during summer; while Red or Black Teas are considered warming teas and often taken in Winter. Pu'er and Wulong (Woolong) Teas are neutral and may taken in all seasons. On the other hand, it's better for the people with warm or hot body condition to take cooling teas while for the people with cool or cold body condition to take warming teas
"One of the things I most like about TCM is the recognition of individuality. This also extends to dietary considerations. There are no "one size fits all" herbal regiments or diets in TCM. Everything is tailored to the individual's needs, and it's recognized that individual needs can differ widely.
The Chinese viewpoint of a balanced diet is very different from that in the West. In the Chinese system, a balanced diet is one which includes all 5 tastes - spicy, sour, bitter, sweet, and salty. Foods and herbs which have a particular taste tend to have particular properties. For example, bitter herbs and foods tend to be drying and Cold. This tends to make them good for treating Damp Heat conditions, but contraindicated for people who are too Cold and/or too Dry. Many of them have antibiotic-like properties. On the other hand, the herbs and foods with a salty taste tend to be warming and moistening. This tends to make them great for treating people who suffer from Cold and Dryness, but they should be used cautiously in people who are Hot and Damp."http://www.acupuncture.com/nutrition/diettcm.htm
