24/7 News Source (Cleveland, OH) -- The Cleveland Clinic is reminding folks to take it easy when shoveling snow. Doctors at the clinic say lifting too much and twisting too far on a repetitive basis can be harmful to your lower back. Shoveling snow can lead to discs in your back to rupture as well as muscle fatigue and discomfort. Lifting less than eight pounds of snow is considered safe. Doctors recommend switching between a few minutes of lifting and throwing snow to a few minutes of pushing or plowing snow. Before heading outside to shovel snow, the Cleveland Clinic recommends conducting a few minutes of simple exercises or stretches to avoid any injury.
