Drinking lemon water can also prevent and treat cardiovascular disease, because Lemon water can relieve the effect of calcium ions on blood coagulation, so it can prevent and assist in the treatment of hypertension and myocardial infarction; lemon water contains a large amount of citrate, which can inhibit the crystallization of calcium salts, thereby preventing the formation of kidney stones, and can even cause some chronic kidney diseases. Stone patients have fewer and fewer stones. Research results announced at the annual meeting of the American Urological Association also show that regular drinking of drinks containing lemon juice can increase the level of citrate in the urine. This chemical can prevent minerals in the urine from forming crystals in the kidneys, which are kidney stones.

Lemons are rich in vitamin C, which has many functions such as antibacterial, improving immunity, and assisting in the production of collagen. Drinking lemon water regularly can supplement vitamin C. When you have a cold, drinking 500 to 1000 ml of lemon water a day can relieve runny nose and make the cold go away quickly.
