What are the benefits of drinking tea?

1. Improve muscle endurance

Drinking tea can improve muscle endurance. This is because tea also contains an antioxidant called catechins, which can increase the body's ability to burn fat, improve muscle endurance, help fight fatigue, and increase the time of physical exercise. Drinking green tea regularly has the most significant effect.

2. Resist UV rays

Tea polyphenols are water-soluble substances. Washing your face with tea can remove facial oiliness, tighten pores, and has the effects of disinfection, sterilization, and anti-skin aging. It also helps reduce the damage to the skin caused by ultraviolet rays in sunlight and is a natural "sunscreen."

3. Stay in shape

The discussion about tea in the Tang Dynasty's "Compendium of Materia Medica" mentioned that "eating it for a long time will make people thin", and modern scientific research has confirmed this. The caffeine in tea can promote the secretion of gastric juice, aid digestion, and enhance the body's ability to break down fat. Foreign studies have also shown that drinking tea regularly can reduce waist circumference and lower body mass index (BMI), thus helping to prevent diabetes and cardiovascular and cerebrovascular diseases.

4. Protect against radiation

Foreign studies have shown that tea polyphenols and their oxides can absorb some radioactive substances, protect cells from radiation damage, and are also helpful in repairing damaged cells. Clinical studies have shown that tea extracts can treat mild radiation sickness caused by radiotherapy in cancer patients, and can effectively treat the decrease in blood cells and white blood cells caused by radiation.

5. Improve memory

Drinking tea also has a certain effect on improving memory. Studies have shown that tea polyphenols in tea can make local improvements to the brain, thereby increasing memory and improving learning efficiency. Foreign studies have confirmed that drinking tea can prevent and treat neurological diseases, especially cognitive impairment in the elderly. In addition, caffeine can stimulate the central nervous system and has the effects of refreshing, improving thinking and clearing the mind.

6. Improve bone density

Although tea contains caffeine, which can promote the loss of calcium through urination, the content is extremely low. Even black tea, which has a high caffeine content, only contains 30 to 45 mg per cup. In fact, tea contains more substances that help reduce calcium loss, including fluoride, phytoestrogens and potassium. A Taiwanese study found that people who drink tea regularly have higher bone density and a lower risk of hip fractures.
