Everyone knows that drinking some health tea at a certain time is good for them, but they don't know when to drink tea. They always think that drinking tea can be done anytime, anywhere, regardless of time and people. But in fact these ideas are all wrong. Although health tea is healthy, people still avoid drinking it. So when should we drink less health tea? Who can't drink tea?

1, drink less tea for five hours.

Never drink tea on an empty stomach, because tea will cool the spleen and stomach and get drunk easily.

It is not advisable to drink tea immediately after meals, because drinking tea before meals will dilute gastric acid, make the diet tasteless, and affect the absorption function of digestive organs.

(3) Drink tea immediately after meals. Tannic acid in tea will condense with protein and iron in food, which will affect the absorption of protein and iron.

④ Tea should not be used instead of medicine, because tannic acid in tea will combine with many drugs to produce precipitation, which will affect the curative effect.

⑤ Drinking tea after drinking won't help hangover, it will only hurt the kidney.

2. Eight kinds of people had better not drink tea.

1, constipation

Tea polyphenols in tea have a certain astringent effect on gastrointestinal mucosa, which will affect the normal digestion and absorption of food by gastrointestinal tract, leading to dry stool and constipation.

2. People with neurasthenia and insomnia

Caffeine in tea has obvious exciting effect on the central nervous system of human body, especially strong tea, which will make the human brain in an overexcited state after drinking and can not get enough rest.

3. Anemia

Tannic acid in tea leaves will precipitate iron in food and will not be absorbed by human body.

4. Calcium deficiency or fracture.

Alkaloids in tea can inhibit the absorption of calcium in duodenum and promote the excretion of calcium in urine, leading to calcium deficiency and osteoporosis, making it difficult to recover from fractures.

5. Patients with gastric ulcer

There is a phosphodiesterase in the stomach that can inhibit gastric parietal cells from secreting gastric acid, while theophylline in tea can reduce the activity of phosphodiesterase and make gastric parietal cells secrete a lot of gastric acid.

6, gout patients

Tannic acid in tea will aggravate the patient's condition, so gout patients should not drink tea, let alone make tea for too long.

7. Patients with hypertension and heart disease

Tea contains caffeine, which has an exciting effect on the human body, and this exciting process will affect the physiological activities of the body and improve some basic metabolism.

8. Fever patients

When a person has a fever, his heart rate and blood pressure are higher than usual. If he drinks tea, his body temperature will rise because of theophylline. In addition, tannic acid will directly affect the discharge of sweat and hinder the normal heat discharge function.

Drinking tea is good for health, but it is not necessarily suitable for everyone. Only when you understand clearly can you enjoy yourself.
