A Canadian hospital conducted a study of efficiency between stairs and elevators.
Stairs won hands down.
Four doctors, aged 26 to 67, were measured taking the stairs in the six story Royal University Hospital in Saskatoon, Sasketchewan.
On average, the stairs took 13 seconds to travel one floor versus 37 seconds for an elevator.
The doctors were able to cut 15 minutes from their work day as a whole.
Sedentary workers are encouraged to take the stairs. If a worker is in a small office building, the stairs are the way to go.
However, this would be harder so a worker in a high rise office.
While the health benefits of stairs haven't been researched, doing light activity throughout the day decreases fat, blood pressure and waist size.
It is still recommended that people find alternative methods to exercise as well.
