In this season when everyone is busy with health preservation, drinking tea is a choice for many in their leisure time. While drinking tea is beneficial to health, it doesn't mean that the stronger and more you drink, the better. Health preservation reminders indicate that regularly consuming strong tea has many disadvantages, which not only wastes tea leaves but also harms physical health.

Health Preservation Reminder: Regular Consumption of Strong Tea Has Many Disadvantages

1. Regular consumption of strong tea may cause constipation. The tea polyphenols in tea have a strong收敛性 on the gastrointestinal mucosa. Strong tea contains high levels of tea polyphenols, making it even more收敛性. This slows down stomach contractions and intestinal peristalsis, thereby affecting food digestion and absorption, and easily leads to dry stool or even constipation.

2. Strong tea has a high fluoride content. Long-term consumption of strong tea can easily lead to dental caries, while also causing teeth to become stained with a layer of enamel black.

3. Due to the relatively high caffeine content in strong tea, regular consumption can lead to a large accumulation of caffeine, which strongly stimulates the entire central nervous system, keeping the brain in an overexcited state. Especially when drinking strong tea at night, it often severely affects sleep.

4. Regular consumption of strong tea can harm bones. This is because strong tea contains high levels 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 inhibited absorption and accelerated excretion, the body becomes deficient in calcium, easily inducing bone calcium loss. Over time, osteoporosis may occur, increasing the risk of fractures.

5. Regular consumption of strong tea, due to the stimulating effects of caffeine, can cause rapid heartbeat, accelerated blood flow, and faster breathing, easily leading to irregular heartbeat or tachycardia.

6. Regular consumption of strong tea can promote excessive gastric acid secretion. This is because the alkaloids in tea reduce the activity of phosphodiesterase, which inhibits gastric acid secretion by gastric wall cells, causing gastric wall cells to secrete large amounts of gastric acid. Over time, this can easily form gastric or intestinal ulcers or make existing ulcers difficult to heal.

7. Regular consumption of strong tea can also inhibit breast milk secretion in nursing women, significantly reducing milk production and affecting the feeding of infants.

8. Excessive consumption of strong tea can cause "tea drunkenness" in people who do not usually drink tea or drink tea on an empty stomach. Symptoms after drinking tea include palpitations, fatigue, irritability, dizziness, blurred vision, and even unsteadiness when standing or walking unsteadily.

Loving tea in daily life is a good thing, but drinking tea should also be done scientifically. Tea should be brewed and consumed immediately, and it is best to drink it light and in moderation. This way, the health benefits of drinking tea can be fully realized.
