The good news is that 15 minutes of snow shoveling counts as moderate physical activity, according to the Surgeon General’s Report on Physical Activity and Health (1996). We all should aim for at least 30 minutes of moderate physical activity of some kind on most days of the week.

A 170-pound person shoveling for 30 minutes will burn about 250 calories. Brisk walking or social dancing are other ways to fit in moderate physical activity during cold winter months.

The bad news is that researchers have reported an increase in the number of fatal heart attacks among snow shovelers after heavy snowfalls. This rise may be due to the sudden demand that shoveling places on an individual’s heart. Snow shoveling may cause a quick increase in heart rate

and blood pressure. One study determined that after only two minutes of shoveling, the heart rates of sedentary men rose to levels higher than those normally recommended during aerobic exercise.

Shoveling may be vigorous activity even for healthy college-aged students. A study performed by researchers at North Dakota State University determined that, based on heart rate, shoveling was a moderately intense activity for college-aged subjects most of the time but was vigorous activity during about one-third of their shoveling time of 14 minutes.

The weather can make shoveling more difficult. Cold air makes working and breathing hard, which adds some extra strain on the body. Shovelers also are at risk for hypothermia, a decrease in body temperature, if they are not dressed correctly for the weather conditions.

This information is not meant to scare you into going out and buying a snow blower. Homeowners on Long Island usually don't have that much driveway and sidewalks so the task is not that demanding. If snow should turn to ice, be very careful and remember to lay down salt for walkers. Its absolutely crucial to make sure your homeowners insurance is updated. Enjoy the snow.
