What happens when you drink green tea at the wrong time?

According to Dr. Huynh Tan Vu, a specialist at the University Medical Center of Ho Chi Minh City (facility 3), green tea leaves contain many chemical components, including flavonoids, triterpene saponins, caffeine, tannin, quercetin, essential oils, ascorbic acid (vitamin C), riboflavin (vitamin B), carotene, malic acid, theophylline, xanthine, oxalic acid, and kaempferol.

Thanks to these substances, green tea leaves have many benefits such as stopping diarrhea, reducing the risk of cancer, protecting cardiovascular health, fighting aging, maintaining healthy bones and joints, improving memory, protecting the liver, controlling blood pressure, preventing complications of diabetes, and reducing the risk of inflammatory diseases.

Drinking tea is very effective in reducing pain from arthritis because EGCG prevents cartilage destruction and reduces swelling. Regularly drinking tea also helps limit the development of diabetes and dangerous complications of blood sugar disorders.

The catechins in tea help increase fat metabolism, making weight loss very safe when combined with exercise.

Furthermore, tea also has detoxifying and anti-inflammatory effects on the body. Tannin compounds neutralize alkaloid toxins such as opium and strychnine, and neutralize excess iron in the body. Theobromine, theophylline, and potassium salts are potent diuretics, helping the body eliminate toxins.

According to Traditional Chinese Medicine, green tea leaves have a bitter and astringent taste, a cooling nature, and act on the Liver and Heart meridians. Green tea has diuretic, calming, heat-clearing, thirst-quenching, digestive, and body-cooling effects.

However, you need to be mindful of the timing of green tea consumption to avoid negative health effects. Green tea is considered cooling in nature, so it shouldn't be consumed cold as it can cause excessive coldness and phlegm production; it should be drunk hot.

Green tea contains a high amount of caffeine, which can cause dizziness, nausea, and lightheadedness if consumed on an empty stomach. The caffeine in green tea stimulates the central nervous system, increasing concentration and brain activity. Therefore, drinking green tea in the evening may cause difficulty falling asleep or insomnia.

You should avoid drinking green tea immediately after meals because tannins can reduce the absorption of iron and other nutrients from food. The tannins in green tea have anti-diarrheal effects, so people with constipation should limit their consumption.

You shouldn't drink tea leaves if you're taking blood-thinning medication because they contain vitamin K. You should drink green tea in the early morning to keep your mind alert and improve your work and study performance.
