Drinking tea regularly may be associated with better cardiovascular health, according to a new study involving nearly 486,000 adults in China. Researchers found that people who regularly consumed tea had an approximately 11% lower risk of vascular diseases, including heart disease, stroke and peripheral artery disease, compared with those who did not drink tea.
The findings add to growing research into how everyday food and beverage choices may influence long-term heart health.
Nine-Year Study Examines Tea Drinking Habits
Researchers followed nearly 486,000 adults for nine years and examined their tea consumption patterns alongside their cardiovascular health.
The results showed that regular tea drinkers had a lower rate of vascular disease. Black tea demonstrated a more consistent association with reduced risk than green tea, while moderate-strength tea was also linked to favourable findings.
The lowest observed risk was recorded among people who reported drinking six to eight cups of tea daily. However, researchers stressed that this does not mean everyone needs to consume that amount.
Lifestyle Habits Also Play an Important Role
The study highlighted that tea consumption was not the only factor associated with better cardiovascular outcomes.
Participants who regularly drank tea, avoided smoking and maintained high levels of physical activity had approximately 45% lower vascular disease risk than those who did not follow these habits.
Tea contains natural plant compounds called polyphenols, particularly flavonoids. These substances are being studied for their potential role in supporting blood vessel function and reducing inflammation.
Very Hot Tea May Not Be a Healthy Choice
Another interesting observation involved the temperature of tea. Participants who preferred drinking their tea extremely hot had a 16% higher risk of vascular disease.
Researchers noted that this finding requires further investigation, particularly because tea temperature was based on participants’ reported preferences rather than direct measurements.
Allowing hot beverages to cool before drinking is a sensible precaution.
Researchers Highlight the Importance of Overall Heart Health
Although the findings are encouraging, the study was observational and cannot prove that drinking tea directly prevents heart disease.
Health experts emphasise that cardiovascular protection depends on several factors working together. A balanced diet, regular physical activity, avoiding smoking, adequate sleep and blood pressure management remain important.
Tea can be part of a balanced lifestyle, but the findings do not establish a recommended daily quantity or mean that drinking more tea guarantees protection against heart disease.
