Study Links Regular Tea Consumption to Lower Cardiovascular Risk, but Warns Against Drinking It Too Hot
Researchers found that tea drinkers had about an 11% lower vascular disease risk, but tea at burning-hot temperatures was linked to a 16% higher risk.
- A Journal of Internal Medicine study of more than 485,000 Chinese adults found drinking tea at least three days weekly linked to a roughly 11% lower vascular disease risk, while 'burning hot' tea raised risk by 16%.
- Tea contains polyphenols and flavonoids, compounds with antioxidant properties that improve arterial flexibility and reduce strain on the heart, helping explain lower rates of strokes and heart attacks.
- Moderate-Strength black tea appeared most protective for participants, with lowest vascular risk occurring at approximately six to eight cups daily, though researchers cautioned against treating this as a specific recommendation.
- Dr. Leana Wen advises avoiding tea hot enough to burn the mouth or throat, noting that repeated consumption of very hot beverages is linked to an increased risk of esophageal cancer.
- Researchers caution that self-reported habits and subjective definitions of 'burning hot' complicate findings, making it difficult to interpret the data as a precise medical recommendation without standardized cup sizes.

The frequency of consumption, the type of tea and the temperature at which it is drunk may influence the association between this drink and the risk of cardiovascular disease. A study conducted in nearly 486,000 adults in China shows that people who regularly drink tea have a lower risk of vascular disease, while drinking at extremely high temperatures has been associated with a higher risk.
Regular tea drinking linked to lower risk of stroke and heart disease
Drinking tea three or more times a week is linked to an 11% lower risk of vascular disease, such as stroke or heart attack, a new study suggests. However, burning hot tea was linked to the opposite effect: a 16% increase in vascular disease risk.
Photo: Shutterstock People who drink tea regularly have a lower risk of heart disease and blood vessel disease, but how they drink it matters: how strong and how hot it is. This is shown by a study of almost half a million adults in China, published today in the Journal of Internal Medicine. Researchers analyzed data from 485,934 adults, […]
One of the important results of this study, published in the Journal of Internal Medicine, shows that the risk of developing vascular disease was about 11 percent lower in people who drank tea at least three days a week, compared to those who drank less tea.
Tea provides significant cardiovascular benefits, but these depend on the type and how it is prepared, according to a new study.
