Many people have this feeling when they drink tea: the first cup of tea is quenched, but the more you drink, the more thirsty you feel. Why?

▪Tea has a strong diuretic effect

The diuretic effect of tea is mainly because the tea soup contains purine compounds such as caffeine, theophylline and theobromine. These components enhance the blood flow of the kidneys and enhance the filtration rate of the glomeruli, thereby achieving the effect of diuresis.
Compared with drinking water, the diuretic effect of drinking tea is 1.55 times higher than that of water. When the body excretes too much water and the intake of water is not enough to supplement the body's needs, it will naturally become more and more thirsty.

When you are very thirsty, avoid drinking tea immediately. You should drink some water first to replenish the water needed by your body before continuing to drink tea.

▪Tea polyphenols cause illusions

This situation often occurs when drinking raw Pu'er and green tea. This feeling is actually not thirsty, but an illusion after the cells are converged. When the tea soup enters the mouth, the tea polyphenols in the tea will form an impermeable film on the tongue. At this time, the tongue will feel dry, making people want to drink more water. But as long as you wait for a while, after this layer of membrane is broken, there will be health care immediately.

▪Drink too much tea in one breath

If you drink a large amount of tea at one time, it will reduce the osmotic pressure inside and outside the body's cells, causing blood dilution and imbalance of electrolytes. At this time, the body will expel the water in the cells for self-preservation, resulting in a temporary increase in intracellular osmotic pressure, and then the symptoms of thirst.
