My morning routine isn't complete without two calming yet energizing cups of green tea.

Not only is a cup of tea highly enjoyable, but it has long been associated with health benefits, including a lower risk of heart disease, stroke and dementia. Now, a new study published Wednesday in the Journal of Internal Medicine suggests that how people prepare and drink their tea could also influence their cardiovascular health.

Over an average follow-up of about nine years, researchers documented more than 14,800 cases of diseases affecting the heart and blood vessels, such as heart attacks, strokes and peripheral artery disease, which involves narrowing of arteries supplying blood to the arms and legs.
