Step outside on a frigid morning and your blood pressure can jump before you reach the mailbox. Cardiologists say winter is the most dangerous season for hearts — here is why.
Cold Constricts Blood Vessels
To conserve heat, the body narrows blood vessels — and the American Heart Association says blood pressure rises within minutes. Winter readings run several points higher than summer ones. Wait 30 minutes after coming inside before checking, cardiologists say.
Shoveling Is the Perfect Storm
Shoveling spikes heart rate and blood pressure together while cold constricts vessels — the combination cardiologists fear most. The AHA warns morning exertion is riskiest, when blood runs thicker. Warm up indoors 10 minutes first, experts say, and push rather than lift.
What Cardiologists Recommend
The AHA advises layers, a scarf over mouth and nose to warm inhaled air, and no alcohol before heading out. Keep blood pressure medication on schedule, cardiologists say, and check readings more often in winter.
Know the Warning Signs
Chest pressure, shortness of breath, or unusual fatigue in the cold warrant immediate medical attention, cardiologists warn. The AHA says call emergency services rather than driving yourself — minutes matter. Never dismiss symptoms as just the chill.
