Drinking too much tea will increase the body’s water content and increase the burden on the heart and kidneys. Drinking too much tea will excite the brain, make the heart beat faster, frequent urination, and insomnia; excessive intake of caffeine in tea is also not good for some diseases. It can be seen that drinking tea needs to grasp the word “degree”. The amount of tea per person per day is related to tea drinking habits, age, health status, living environment, customs and other factors.
Generally healthy adults, who usually have tea drinking habits, can drink about 12 grams of tea a day, it is advisable to brew 3-4 times. It is also suitable for people with a large amount of labor, heavy physical exertion, and a large amount of food, or for people who are engaged in high-temperature and toxic substance occupations. People who use beef and mutton as non-staple food and have eaten fatty foods, as well as smokers and alcoholics, can increase the amount of tea appropriately.
The elderly, children and pregnant women should reduce the amount of tea appropriately, and generally drink light tea. For the elderly, especially those over 50 years of age, avoid excessive drinking of tea, because ingesting more caffeine, etc., symptoms such as insomnia, tinnitus, dazzling, arrhythmia, and a large amount of urination may occur.
Elderly people with heart disease should drink tea mildly and lightly, and do not drink tea at night, and drink boiled water after dinner as well. As the elderly grow older, the secretion of various digestive enzymes in the digestive system decreases, which reduces digestive function. If you drink a large amount of tea, it will dilute the gastric juice and affect the digestion and absorption of food. At the same time, the gastric acid will also be diluted, which will reduce the defense function of killing bacteria in the gastrointestinal tract. Once the pathogenic bacteria enter, it is easy to infect gastrointestinal diseases.
Most of the elderly have bad teeth, eat less fiber-containing vegetables, and they have less movement, which slows down bowel movements and is prone to constipation. If you often drink strong tea, the tea tannic acid combines with the protein in the food to form a block of digested and absorbed protein, which will make constipation worse.
Renal benefits of the elderly gradually declines, and symptoms of urinary incontinence often occur. Drinking too much or too much tea, the diuretic effects of theophylline, etc., will inevitably increase the burden on the kidneys and urinary incontinence symptoms, which will bring greater pain to the elderly.
