Ms. Tam, 72, with a long history of high blood pressure, recently collapsed suddenly; doctors diagnosed a stroke caused by the narrowing of two blood vessels supplying her brain.
Green tea, beetroot juice, pomegranate juice, and oat milk contain antioxidants and nitrates that relax blood vessels, reduce inflammation, and help stabilize blood pressure.
Falling temperatures can cause erratic blood vessel constriction, leading the body to retain salt and water, which results in a more pronounced blood pressure increase, especially in older adults and those with pre-existing conditions.
