How weather affects your blood pressure (and what you can do about it)

Weather fluctuations significantly impact blood pressure, posing risks for those with hypertension. Hot weather can lower blood pressure through vasodilation, but dehydration can reverse this effect. Conversely, cold temperatures raise blood pressure via vasoconstriction. Experts advise regular blood pressure monitoring, staying hydrated in the heat, and maintaining warmth and a healthy lifestyle during winter to manage these weather-related shifts effectively.
