2. Increased Blood Pressure
According to research from the Mayo Clinic, the cold weather can shrink the diameter of your blood vessels, taxing your circulation system and increasing the workload on your heart. This could cause a heart attack if you are already at risk.
The clinic recommends monitoring your blood pressure if you’re going out into frigid conditions, to ensure there are no big changes. Your doctor can combat this effect of the cold on your heart by adding or changing your dose of blood pressure medication.
