Drinking tea is a good habit, especially for people who spend long hours in front of computers, which is bad for eye health. Experts say that drinking tea daily not only reduces the harm from radiation but is also beneficial for protecting your eyes! However, the following ten types of people should not drink tea. See if you are among them:
People with iron-deficiency anemia
Tannins in tea can affect the body's absorption of iron, worsening the anemia.
People with neurasthenia
The caffeine in tea can be stimulating, increasing basal metabolism and worsening insomnia.
Patients with active gastric ulcers
Caffeine stimulates gastric acid secretion, aggravating the condition and affecting ulcer healing.
People with urinary tract stones
Oxalate in tea can lead to an increase in stones.
People with poor liver function
The majority of caffeine is metabolized by the liver. Drinking tea will increase the burden on the liver for those with poor liver function.
People with constipation
Tannins have an astringent effect, which can weaken intestinal peristalsis and worsen constipation.
Nursing mothers
Caffeine can pass into a baby through breast milk, causing the infant to suffer from intestinal cramps and anemia, and it can also affect the baby's sleep.
People with heart disease
Drinking too much tea can speed up the heartbeat, and in some cases, it can cause arrhythmia.
Pregnant women
Drinking too much tea can lead to a small and weak baby.
People who are drunk
Alcohol is a great stimulant to the cardiovascular system. Caffeine can speed up the heartbeat. The combined effect of the two is very dangerous for people with poor heart function.
