Avoid drinking strong tea: tea can generally stay in the human body for about 3 hours, while strong tea stays longer, which makes theophylline accumulate too much in the human body, leading to neurological disorders. Due to the effect of tannic acid in tea, the function of mucus secretion of intestinal mucosa can be reduced, resulting in constipation. The amount of tea is generally 5~ 10 g per day, and it is appropriate to soak it twice.
When drinking tea, you should drink it immediately, and avoid making tea water for a long time: soaking for a long time will not only lose the fragrance of tea, destroy the vitamins in tea, but also produce certain substances, which will stimulate the human body after drinking, especially those who suffer from gout, cardiovascular and nervous system diseases, and should avoid drinking tea soaked for a long time.
Avoid drinking tea on an empty stomach: the ancients once said that "it is better to have a cup of tea early than to have a robber in a poor house", which means it is not advisable to drink tea on an empty stomach in the morning. Because drinking tea on an empty stomach will dilute gastric juice, reduce the function of gastric acid, hinder digestion, affect the absorption of protein, and easily cause gastric mucosal inflammation.
Avoid drinking tea before going to bed: it is best not to drink tea two hours before going to bed, otherwise it will make the spirit too excited and affect sleep, and even cause insomnia. Drinking tea before going to bed in the elderly can easily lead to anxiety and polyuria, which will also affect sleep. If insomnia is caused by drinking tea, it is useless to use sleeping pills.
Avoid drinking overnight tea: tea leaves will not only lose nutrients such as vitamins, but also be prone to rancidity and deterioration. Even the tannic acid in tea will become a very irritating oxide, which is easy to hurt the spleen and stomach, especially in summer, which will cause gastrointestinal inflammation.
There is a saying among the people: "Hot tea hurts the body, digestion after meals, insomnia in late tea, palpitation in empty tea, spleen and stomach injury in overnight tea, and wasting away with too much tea." When drinking tea to relieve summer heat in summer, we must be cautious, remember the taboo of drinking tea, avoid the disadvantages caused by improper drinking tea, and achieve the effect of relieving summer heat and health care.
