With heavy snow headed for Arizona Thursday and Friday, it's a good time to think of heart health.

The risk of a person having a heart attack increases when doing the rigorous task of shoveling snow, according to the American Heart Association.

Cold temperatures and raised blood pressure can be a bad combination. Always check with your doctor before any physical activity, especially if you have heart conditions.

The American Heart Association offers some tips:

• Take breaks. Don't overstress your heart. Pay attention to your body during these breaks.

• Learn the heart attack warning signs, including chest discomfort, upper body discomfort, shortness of breath, cold sweat, nausea or lightheadedness.

• Don't eat a heavy meal before or soon after shoveling.

• Avoid alcohol before or soon after shoveling.

• Consult a doctor.

If you or someone you see appears to be experiencing a medical emergency, time is of the essence. Call 911 right away.
