Tea for Health: Drink Dark Tea at Night to Strengthen Intestinal Flora Activity

Tea News · May 26, 2026

 

Tea is generally divided into three types: green tea, black tea, and dark tea. Green tea is unfermented, black tea is semi- or fully fermented, and dark tea refers to fully fermented tea that has been stored for a longer period of time.

Drink dark tea at night to strengthen intestinal flora activity

Dark tea, due to its longer storage time, contains many probiotics. According to traditional Chinese medicine, after a meal is the most yin time of the day, when the spleen and kidneys need a quiet environment to function and regulate.

Drinking dark tea after a meal allows the probiotics in the tea to enter the gastrointestinal tract, accelerating the digestive system's operation and improving absorption efficiency. With improved digestion efficiency and shortened time, the body can enter a quiet state sooner.

Dark tea is mild in nature and does not affect sleep. The preferred dark tea is Yunnan Pu'er. It should be noted that although dark tea has a mild flavor, older adults should avoid drinking it too strong.

Anhua dark tea nourishes the stomach and aids sleep? Anhua dark tea is gentle on the spleen and stomach, causing relatively little stimulation. It promotes metabolism, accelerates the breakdown and transformation of body fat and toxins, and long-term consumption can nourish and protect the stomach. In addition, Anhua dark tea is a post-fermented tea. During fermentation, the polyphenols undergo strong oxidation, reducing their content to about 15% or even less, while the content of tea polysaccharides and gallic acid significantly increases, greatly reducing irritation to the stomach and nerves. Therefore, drinking Anhua dark tea at night does not cause insomnia, and both domestic and international studies have shown that Anhua dark tea has a noticeable calming effect.

Green tea enters the liver, suitable for morning drinking

According to traditional Chinese medicine, green color enters the liver. Drinking green tea in the morning can clear liver fire, reduce fat, and soothe internal heat. It is also rich in vitamin E, which can delay aging. The morning is typically the most active period of the day, and a cup of green tea in the morning can keep you refreshed throughout the morning. Additionally, green tea has a high content of polyphenols, which have antioxidant and anti-inflammatory effects.

It should be noted that people with weak stomachs should dilute green tea before drinking.

Afternoon black tea nourishes the heart

After a morning of activity, the body gradually enters an adjustment period in the afternoon. This adjustment period involves coordinating the body with the external environment and internal systems. At this time, the role of the heart becomes particularly important. The heart governs the circulatory system, which is a key basis for the body's adjustment of its physical state.

Black tea enters the heart. Drinking black tea can promote the operation of the digestive system and blood circulation, dispel internal cold, and ensure adequate blood supply. At the same time, black tea is mild in nature and can relieve tension.

When drinking black tea, you can add some seasonings such as milk, sugar, lemon, or honey. It is important to note that you should never drink tea on an empty stomach, as it may cause palpitations, frequent urination, and other adverse reactions. Over time, it may also affect the body's absorption of vitamin B.

Older adults should drink clear and mild tea

First, drinking tea can alleviate anxiety and help express emotions. Second, drinking tea can become an interest and a pastime, bringing regularity to the lives of older adults. Finally, tea gatherings can add a lot of fun to daily life.

Bin Wei reminds that when drinking tea, older adults should choose clear and mild tea, and also avoid drinking hot tea too quickly. For those who are weak, have poor digestion, slow fat metabolism, or suffer from cardiovascular diseases, drinking tea is very beneficial.
