What are the dangers of strong tea

China's tea culture has a long history. The habit of drinking tea has existed since ancient times. There are many varieties of tea, such as black tea, green tea, and scented tea, which are all well-known. Different types of tea have different effects. Many people have the habit of drinking tea, but most people just drink tea blindly. How many people know the correct way to drink tea? Drinking strong tea is not good for your health. Let us learn about the hazards of strong tea.

Since strong tea contains relatively more caffeine, if you drink strong tea regularly, the large accumulation of caffeine can have a strong stimulating effect on the entire central nervous system, causing the brain to be in an over-excited state. Drinking strong tea at night, in particular, can often seriously affect sleep.

Drinking strong tea regularly can easily damage your bones. This is because strong tea contains a lot of caffeine, which can inhibit the duodenum's absorption of calcium and accelerate the excretion of calcium in urine. Due to the dual effects of inhibiting absorption and accelerating excretion, calcium deficiency in the body can easily induce calcium loss in the bones. Over time, osteoporosis will occur and fractures are likely to occur.

Drinking strong tea regularly can cause the stimulating effect of caffeine to cause rapid heartbeat, accelerated blood flow, and quicker breathing, which can easily lead to irregular heartbeat or tachycardia.

Drinking strong tea can cause excessive secretion of gastric acid. Because the bioalkali in tea can reduce the activity of phosphodiesterase which can inhibit the secretion of gastric acid by gastric parietal cells, causing the gastric parietal cells to secrete a large amount of gastric acid, which can easily form gastric and intestinal ulcers over time or make existing ulcers difficult to heal.

Drinking strong tea regularly may cause constipation. The tea polyphenols in tea have a strong astringent effect on the gastrointestinal mucosa. The tea polyphenol content in strong tea is high, and the astringent effect is even stronger. It will slow down the contraction of the stomach and the peristalsis of the intestines, thus affecting the digestion and absorption of food, and easily causing dry stools or even constipation.

Drinking strong tea regularly can also inhibit breast secretion in breastfeeding women, greatly reduce milk production, and affect breastfeeding of babies.

Drinking too much strong tea can also cause "tea drunkenness" in people who do not drink tea often or drink tea on an empty stomach. That is, after drinking tea, they feel palpitations, fatigue, irritability, dizziness, blurred vision, and even unsteady standing and staggering.

The harm of drinking strong tea cannot be underestimated. It may not be a problem if you drink it once or twice, but after a long period of time, it will cause great harm to the body. Especially after knowing the harm of strong tea, we should change these improper habits of drinking tea to avoid causing greater harm to the body. We must be responsible for ourselves.
