When people are relaxing as visitors, they are often accompanied by tea. Tea contains nutrients such as tea polyphenols, aromatic oils, minerals, proteins, and vitamins. It has effects such as refreshing the mind, relieving fatigue, lowering fat and aiding weight loss, reducing inflammation and detoxification, and promoting the production of body fluids to quench thirst, making it very popular among people.
However, tea should be light rather than strong; otherwise, it will have the opposite effect. Especially for people suffering from the following diseases, they must not drink too much.
Gastric Ulcer
Strong tea can increase gastric acid secretion, which increases the stimulation on the ulcer surface, affects healing, and worsens stomach problems. At the same time, drinking strong tea while taking medication can reduce the effectiveness of stomach medicine and is not conducive to recovery from the disease.
Arrhythmia
Tea contains substances like theophylline, which have a significant excitatory effect on the central nervous system, causing a rapid increase in heart rate, leading to tachycardia, and even causing symptoms of palpitations. This is a potential threat for patients with cardiovascular and cerebrovascular arteriosclerosis. A large amount of strong tea entering the blood increases blood volume, which can加重 the burden on the heart and worsen the degree of heart failure.
Hyperthyroidism
Patients with hyperthyroidism already have a high basal metabolic rate. If they consume large amounts of caffeine from tea, it will accelerate metabolism, leading to an increased consumption of various nutrients, which prevents hyperthyroidism patients from getting adequate rest and worsens their condition.
Glaucoma
Strong tea can stimulate the nervous system, causing intraocular pressure to rise. In severe cases, it can cause the expansion of capillaries in the eyeball, worsen eye congestion, and even lead to an acute attack of glaucoma.
Gout
Tea contains purine compounds, which can exacerbate gout symptoms. Therefore, patients with gout should drink less tea.
Kidney Stones, Constipation
Because tea contains tannic acid, which promotes the formation of stones, it is very detrimental to the prevention of kidney stones and the control of the condition. Therefore, patients with kidney stones should not drink strong tea. In addition, the tannic acid in strong tea has the effect of reducing the secretion of mucus by the intestinal mucosa, which decreases intestinal fluid secretion and fails to lubricate the intestines. The retention time of feces in the intestines is prolonged, the intestinal wall absorbs excessive moisture from the feces, causing dry stools and difficulty in defecation. Therefore, people with constipation should also drink less.
Depression
Strong tea can easily make people excited, worsening the insomnia symptoms of patients with depression. It is recommended that they drink some light tea appropriately in the morning.
