Drinking tea is good for health, but a wrong habit can increase the risk of disease.

Many people know that tea contains polyphenols, catechins and other elements that are helpful to the human body. Drinking tea in limited quantity is good for health. However, a recent study found that the temperature of tea water may affect the risk of disease.cardiovascular disease risk. USA Today reported that a new study showed that people who drank tea more than three days a week had about an 11% lower risk of developing vascular disease than those who drank tea less often. However, people who drank “strong” tea had a higher risk than those who drank tea less often.

This Chinese study, recently published in the Journal of Internal Medicine, followed more than 485,000 subjects for nine years. Subjects ranged in age from 30 to 79 years and recorded more than 14,800 cardiovascular events, such as myocardial infarction,stroke and peripheral artery disease. The study results only show that the temperature of tea is related to disease risk, but do not prove that drinking tea at a specific temperature will cause or prevent disease. The researchers based their analysis on participants’ statements about their tea-drinking habits, and other differences in lifestyle may have influenced the findings.

According to the study, people who said they drank “strong” tea had a 16% higher risk of heart disease than people who did not drink tea regularly. In comparison, people who drink tea at room temperature or at moderate temperatures have a lower risk of disease than those who do not drink tea regularly. The findings suggest that the temperature of the water in which tea is brewed may be a factor worth considering, but the study does not confirm that the temperature of the water itself causes differences in disease risk.

Researchers found that people who drank strong tea regularly had a lower risk of developing vascular disease than people who did not drink tea regularly. When comparing different teas, black tea is associated with a lower risk of many vascular diseases than green tea. CNN reported that tea contains compounds called polyphenols, which include flavonoids. Some studies have studied the potential antioxidant and anti-inflammatory effects of these compounds, but studies have not confirmed whether these compounds can explain the association between tea drinking and vascular disease risk.

The researchers found that among those who drank tea at least once a week, those who drank about six to eight cups of tea a day had the lowest risk of vascular disease. However, the findings don’t mean everyone should start drinking six to eight cups of tea a day. The researchers did not determine how much tea should be drunk to prevent disease, and the findings were based on subjects’ descriptions of their tea drinking habits.
