Therefore, in summer health care, we must first pay attention to nourishing the heart. Green tea contains flavonols, which have good antioxidant effects.

"Summer is a yang evil, and excessive heat is accompanied by dampness, which easily consumes qi and damages body fluids."

The weather is hot in summer and people tend to sweat, which causes the body to lose a lot of potassium ions. According to scientific proof, green tea contains a large amount of potassium, which can promptly replenish the potassium lost by the body. This is beneficial to the production of body fluids and qi, making up for physical losses and improving heat resistance.
