You may have always thought that tea is just a thirst-quenching or refreshing drink, but today, we want to tell you a counterintuitive point: tea actually has many unknown health benefits.
Next, we will reveal to you 11 health benefits of tea to help you fully understand the charm of this natural and healthy drink .
Health Benefits of Tea: Find the ideal way to relax your body
Theanine and other ingredients in tea make it an ideal way to relax your body . Tea is rich in theanine, which can accurately regulate the release of brain neurotransmitters, especially gamma-aminobutyric acid (GABA)【1】.
GABA is like a calm commander, guiding the activity of brain neurons to gradually stabilize, allowing those nerves that are tense due to life pressure to slowly relax.
Scientifically proven to calm and relax people who drink green tea, giving it an anti-anxiety effect【2】 , EGCG has been found to protect against nerve damage and Huntington’s disease, as well as ALS and other neurodegenerative diseases that are more common today.
EGCG-rich green tea extracts have also been found to be an effective treatment for neurodegenerative diseases.
Health Benefits of Tea：product to slow down aging
As we age, our bodies are gradually damaged by free radicals, leading to problems such as sagging skin and increased wrinkles.
The polyphenols in tea, especially catechins such as epigallocatechin gallate (EGCG), are powerful antioxidants that can scavenge free radicals in the body and reduce oxidative stress-induced cell damage【3】.
It helps slow down the aging process and maintain skin’s elasticity and radiance. Regular consumption of tea, especially green and white tea, can help you radiate youthfulness from the inside out.
Green tea is particularly rich in tea polyphenols, especially catechins such as epigallocatechin gallate (EGCG), which has an antioxidant capacity dozens of times that of vitamin C and hundreds of times that of vitamin E【4】.
Health Benefits of Tea: Make your stomach feel comfortable
The polyphenols and caffeine in tea together constitute a system of ingredients that protect the stomach and intestines.
Modern people’s eating habits are often irregular, which can easily lead to gastrointestinal discomfort. However, some ingredients in tea are like “little guards” of the stomach and intestines, which can promote gastrointestinal motility and enhance digestion.
The polyphenols and caffeine in tea can promote the secretion of gastric juice, enhance gastrointestinal motility and help digestion【5】.
At the same time, they can inhibit the growth of harmful bacteria, protect the intestinal mucosa, and prevent gastrointestinal diseases.
Theaflavins and other ingredients in black tea promote the growth of beneficial intestinal bacteria and regulate the balance of intestinal flora, making it particularly suitable for people with weak stomachs and cold intestines【6】.
Health Benefits of Tea: Rejuvenate the spirit
The caffeine and tea polyphenols in tea work together to refresh the brain.
The caffeine in tea can stimulate the central nervous system, increasing alertness and concentration【7】.
Compared with coffee, tea has a moderate caffeine content and contains soothing ingredients such as tea polyphenols, which can avoid the side effects of excessive caffeine.
Therefore, drinking tea can not only refresh the mind, but also keep you calm and focused.
The theanine in oolong tea can also alleviate the excitatory side effects of caffeine, allowing you to refresh yourself without feeling too nervous【8】.
Health Benefits of Tea: A healthy aid for lowering blood sugar
The polyphenol compounds in tea, especially catechins, are effective in lowering blood sugar【9】.
For diabetics and people with high blood sugar, controlling blood sugar is very important.
The polyphenol compounds in tea are a hidden “sugar control expert” . Catechins among polyphenol compounds are believed to have a significant blood sugar lowering effect.
Specifically, EGCG can act on the insulin signaling pathway, increase the responsiveness of cells to insulin, and thus promote glucose metabolism【10】.
In addition, the antioxidant components in white tea also help regulate blood sugar and prevent diabetic complications.
Health Benefits of Tea: Guardian of Teeth
The fluoride and polyphenols in tea together form a line of defense to protect your teeth.
Having white and healthy teeth is the dream of many people, and tea is a natural helper to realize this dream.
The fluoride and polyphenols in tea have a protective effect on dental health.
Fluoride can enhance teeth’s resistance to acid and prevent tooth decay【11】.
Polyphenols have antibacterial effects and can inhibit the growth of oral bacteria and reduce the formation of dental plaque【12】.
Regular consumption of tea, especially green tea, can help keep your mouth clean and prevent periodontal disease.
Health Benefits of Tea: boost your metabolism
The caffeine and tea polyphenols in tea have the dual effects of diuresis and promoting metabolism.
The caffeine and tea polyphenols in tea have a diuretic effect, which can promote the excretion of excess water in the body and thus relieve edema symptoms【13】.
At the same time, tea can promote metabolism, accelerate the decomposition and excretion of fat, and help control weight【14】.
This is undoubtedly good news for people who need to manage their weight or are troubled by edema.
For people who suffer from lower limb edema due to long-term sitting, long-term standing or improper diet, drinking a moderate amount of light black tea can relieve edema to a certain extent and bring a sense of relaxation.
In addition, black tea can promote blood circulation, improve the body’s metabolic efficiency, and help excrete toxins from the body.
Health Benefits of Tea: Antibacterial and anti-inflammatory
In our daily lives, we are inevitably attacked by bacteria and viruses.
The polyphenols in tea have powerful antibacterial and anti-inflammatory effects【15】.
They are able to inhibit the growth of a wide range of bacteria and viruses, including common pathogens that cause infection.
For example, catechins in green tea have been shown to have inhibitory effects on a variety of bacteria, helping to fight infection and promote wound healing【16】.

Antioxidants such as vitamin C, E and carotenoids in tea have an all-round protective effect on eye health【17】【18】.
It can protect the retina from damage by free radicals and prevent eye diseases such as cataracts and macular degeneration.

Cardiovascular disease is a major threat to human health, and tea is a loyal guardian of cardiovascular health.
The cardiovascular health benefits of tea have been widely researched and recognized.
The polyphenols in tea can lower cholesterol levels, reduce fat deposits in blood vessel walls, and prevent atherosclerosis. At the same time, they can dilate blood vessels, lower blood pressure, and reduce the risk of heart disease and stroke【19】.
Green tea and white tea are particularly rich in antioxidants, and their protective effect on cardiovascular health is more significant.
The oxidation of LDL-C is one of the important causes of cardiovascular disease, and tea polyphenols can reduce its oxidation degree, reduce its deposition in the blood vessel walls, protect vascular endothelial cells, and maintain the normal function of blood vessels【20】.
Health Benefits of Tea: Give you the power to prevent disease
Polyphenols in tea have anti-cancer potential【21】.
They can inhibit the growth and spread of cancer cells and induce apoptosis of cancer cells, thereby preventing the occurrence of cancer.
