According to some Chinese doctors, eating spicy foods and drinking cold water together on a daily basis for a prolonged period of time are not recommended. The theory behind this caution as proposed by these Chinese doctors is somewhat interesting but the theory leads to a rather illogical concluslion.
According to the theory, eating spicy foods repeatedly stimulates localized hyperaemia in the stomach, causes generalized edema and leads to constipation. Food remnants from digestion remain in the intestines and harbor all kinds of bacteria that may pierce the capillaries and the lymph glands, and in women, the bacteria may enter the fallopian tubes and the ovaries and may cause inflammation of peripheral organs and blockage of the fallopian tubes.
When eating spicy foods with a lot of cold water, the cold water may cool down the blood in the intestinal wall and in the pelvic muscles. This in turn may cause menstrual pain and irregular menstruation, and the uterus may shrink and harden. The ovaries may become swollen and this may lead to adenasthenia, adenomyoma and adenomyomatosis.
That is the theory. As we know, spicy foods make us sweat, and increase circulation, heart rate, and heavy breathing.
We also know that cold water lowers the body temperature, and at freezing temperatures, circulation slows and the muscles tighten. When sleeping in a cold bedroom and in a cold bed, the legs go into cramps when they become too cold.
Drinking a cold drink after eating spicy foods is a way to reduce the burning of the tongue. They are antidotal. Cold water dulls the burning sensation while hot water and hot tea enhance the burning sensation of the tongue.
However, the theory comes into doubt when such abnormal growths as adenasthenia, adenomyoma and adenomyomatosis are attributed to a combined ingestion of spicy foods and cold water. And an extention of the effect of cold water on the pelvic muscles, according to the theory, would lead us to conclude that women living in cooler climates should have more severe menstrual cramps than women living in the Tropics. This conclusion would put the validity of the entire theory into doubt.
