In hot summer, many old people like to drink tea to cool off the heat. Having a cup of tea and a newspaper at hand is the most comfortable life for many retired people in their later years. But everything has two sides. Drinking tea is good for your health, but it is also stressful. Only drinking tea correctly can be good for your health, otherwise it will be bad for your health.

Tea has a good health-preserving effect, but if you drink tea in the wrong way, it will do harm to your body. Therefore, drinking tea should follow three principles, namely: early, little and light.

After entering old age, people's sleep time is reduced, the quality of sleep is not high, and the excitement of drinking tea will last longer. Even if the elderly drink tea in the afternoon, they may lose sleep at night, shorten their rest time and feel depressed the next day. If you refresh yourself by drinking tea in the future, you will fall into a vicious circle. Therefore, it is best for the elderly not to drink tea before meals, in the afternoon and before going to bed. It is best to drink tea about half an hour after breakfast, which can help digestion, relieve greasy and clear the stomach. Drinking tea in the afternoon may affect the quality of sleep at night.

Generally speaking, after the exciting effect of tea is sent to various tissues and organs of the human body, it will drive muscles and blood vessels to tighten and contract accordingly, which will lead to a rapid increase in blood pressure. The elderly themselves are prone to diseases such as arteriosclerosis and hypertension, so drinking too much tea will increase the incidence of critical symptoms such as stroke. Experts suggest that the elderly should control the amount of tea they drink according to their own situation. Among different people, patients with hypertension and obese people with good constitution should drink green tea, while those with weak constitution and cold stomach should drink black tea.

In addition, too strong tea will produce too strong stimulation, so that cardiovascular and receptors will gradually become dependent, thus losing their normal functions. Caffeine in strong tea can also make the human heart beat faster, thus raising blood pressure, increasing the burden on the heart and causing discomfort such as chest tightness and palpitation. Old people have a bad heart. Drinking strong tea for a long time will add extra burden to the heart, lead to tachycardia and arrhythmia, and even induce and aggravate various heart diseases.
