A study published in the *Journal of Internal Medicine* on October 21, 2026, tracked 485,934 adults in China aged 30 to 79 for a median of 9.05 years, recording 14,863 cases of cardiovascular disease, cerebrovascular disease, pulmonary heart disease and peripheral artery disease.

People who drank tea at least three days a week had an 11% lower risk of these vascular outcomes than non-tea drinkers, with the lowest estimated risk among weekly drinkers consuming roughly 6–8 cups per day — a figure the researchers cautioned should not be read as a daily target.

The counterintuitive result is the temperature finding: drinking tea described as 'burning hot' was associated with a 16% increase in vascular disease risk, the opposite of the benefit seen with regular consumption.

Strength mattered too — moderate-strength tea showed the lowest risk, and black tea showed more consistent inverse associations with vascular disease than green tea.

The pattern held even after researchers adjusted for smoking, exercise and body weight, meaning the association could not be explained away by healthier lifestyles alone.

The daily mirror of lifestyle detail is what gives the study weight: participants reported not just frequency but tea type, brewing strength and drinking temperature, letting researchers separate those variables.

The strongest combined effect came from behavior, not brewing — the *Daily Mirror* reports that combining habitual tea drinking with noncurrent smoking and high physical activity was associated with a 42.5% lower vascular disease risk, the lowest of any group.

Researchers themselves stressed that self-reported 'burning hot' temperatures are subjective and that the observational design cannot prove tea prevents disease.

According to *Yahoo Health*, emergency physician Dr. Leana Wen explained that tea's polyphenols — natural compounds with antioxidant and anti-inflammatory properties — may help blood vessels relax, improve blood pressure and reduce strain on the heart. *SSBCrack News* adds that tea's flavonoids may protect the blood vessel lining and aid arterial relaxation and expansion.

There is also a simpler benefit: swapping sugary drinks for unsweetened tea cuts sugar intake, which supports weight management and cardiovascular health.

Experts warned against treating tea as a silver bullet. *Daily Mirror* quotes British Heart Foundation senior dietitian Dell Stanford, who was not involved in the study, saying other differences in people's diets and lifestyles could help explain the findings and that the results don't prove 'a daily cuppa protects your heart.'

Extremely hot beverages have also been linked to esophageal cancer risk, so letting tea cool matters.

For non-tea drinkers, the practical takeaway is modest: the authors said people not currently drinking tea should focus on established heart-protection measures — healthy diet, regular exercise and avoiding smoking.

The temperature finding opens a fresh research question, since self-reported heat perception varies widely and the authors flagged that objective temperature measurement may be needed in future work.

For now, the consensus from both the study and outside experts is that tea can be part of a heart-healthy pattern, provided it is moderate in strength and never scalding.
