Jan 31, 2026
Dr. John Osborne, cardiologist and American Heart Association volunteer, explains why shoveling snow can push the heart to its limits. He describes how heavy, wet snow and cold amplify strain. Short bursts can near-max your heart rate. Practical tips cover pacing, dressing in layers, and avoiding sudden, intense exertion.

Episode notes
Snow Shoveling Is A Heavy Cardiovascular Load
- Shoveling snow can push most people to about 97% of their predicted maximal heart rate within 10 minutes.
- Cold plus exertion raises heart rate and blood pressure, creating a major cardiovascular stress.
Ask For Help If You Have Heart Risks
- If you have heart disease, diabetes, prior stents or bypasses, or high blood pressure, be very cautious and ask for help.
- Older adults (above about 45–65) should avoid heavy solo shoveling and get assistance.
Upper-Body Strain Drives Risk
- Much of the work of shoveling uses upper-body muscles, which are not as strong as lower-body muscles.
- That imbalance increases strain and injury risk, especially for older or deconditioned people.
