Why do you drink more water in summer?

Because the summer weather is hot, after breathing, body surface will take away a lot of water. Although drinking more water, but by the body surface, breathing will evaporate a lot of water, the actual effective water into the blood circulation is still not enough, into the kidney blood flow is still not enough, so the formation of urine is still relatively small. A large amount of urine can discharge metabolites from the body. If the urine volume is small, a large amount of nitrates will accumulate in the body, which is easy to cause stone formation.
