1, pay attention to drinking health tea
1. Qingre tea.
Some people have bad breath, dry throat, yellow urine and feel angry, so they often drink some "herbal tea" such as honeysuckle tea, chrysanthemum tea and boat-fruited Sterculia tea to purge the fire. It may have a certain effect at first, but after a long time, it often leads to colds, indigestion, cough and phlegm, sore throat, dry throat and other symptoms can not be completely eliminated. This is because drinking a health tea for a long time will inevitably damage the yin essence or Yang Qi, which will lead to imbalance between yin and yang and reduce the disease resistance of human body.
2. laxative tea.
Because of diet structure, living conditions, mental stress and other reasons, the incidence of constipation is very high, especially in middle-aged and elderly people. Many people will choose senna, rhubarb, cassia seed, aloe and other Chinese herbal pieces instead of tea. At first, they often have an immediate laxative effect, but drinking for too long will hurt the middle qi and cause side effects such as shortness of breath, listlessness and organ prolapse.
3. slimming tea.
Slimming tea generally contains ingredients such as Fructus Toosendan, Radix Sophorae Flavescentis, Cortex Cinnamomi, etc., which can inhibit appetite, promote metabolism, induce diuresis and stop diarrhea, and reduce the absorption of carbohydrates and lipids. If you drink these slimming teas for a long time, you may have side effects such as abdominal pain, diarrhea, upset and loss of appetite. In addition, the initial use of slimming tea often has a certain effect, but if there is no exercise, diet and other conditioning measures to keep up, it will often rebound after a long time, and all previous efforts will be in vain.
2. The health care function of drinking tea
1, improve muscle endurance. Studies have found that tea contains an antioxidant called catechin, which can increase the body's ability to burn fat, improve muscle endurance, help fight fatigue and increase physical exercise time. Drinking green tea is often the most effective.
2. resist ultraviolet rays. Tea polyphenols are water-soluble substances. Washing your face with tea can remove greasy face, astringe pores, have the functions of disinfection, sterilization and anti-aging, and also help to reduce the damage of ultraviolet rays in the sun to the skin. It is a natural "sunscreen".
3. Stay in shape. The discussion on tea in Compendium of Materia Medica in the Tang Dynasty once mentioned that "eating for a long time makes people thin", which was confirmed by the Institute of Modern Science. Caffeine in tea can promote the secretion of gastric juice, help digestion and enhance the body's ability to decompose fat. Foreign studies also show that drinking tea regularly can reduce waist circumference and body mass index (BMI), thus helping to prevent diabetes and cardiovascular and cerebrovascular diseases.
4. Radiation resistance. Foreign studies show that tea polyphenols and their oxides can absorb some radioactive substances, protect cells from radiation damage and help repair damaged cells. Clinical research shows that tea extract can treat mild radiation sickness caused by radiotherapy in tumor patients, and treat hemocytopenia and leukopenia caused by radiation with good effect.
5. Improve memory. Tea polyphenols contribute to local brain adjustment, improve memory and improve learning efficiency. Foreign studies have confirmed that drinking tea can prevent and treat nervous system diseases, especially the cognitive impairment of the elderly. In addition, caffeine can stimulate the central nervous system, which has the functions of refreshing, benefiting the heart and clearing the heart.
6. Improve bone density. Although tea contains caffeine, it will promote the loss of calcium with urination, but the content is extremely low. Even black tea with high caffeine content is only 30~45 mg per cup. In fact, tea contains more substances that can help reduce calcium loss, including fluorine, phytoestrogens and potassium. A study in Taiwan Province found that people who drink tea regularly have higher bone density and lower probability of hip fracture.
