HI Dolly, am not sure I know the answer to this question. From my knowledge, whenever we engage in any activity, we burn calories as we consume energy. Since clicking a mouse is not an energy-intensive activity, and dose not involve many muscles (as muscles contract when we engage in physical activity resulting in energy use) I would expect one to burn very minimal amounts of calories while doing so. My approximation is 2 calories?
@dolly da gucci,
My best guess is very little! You are more likely to end up with muscle and joint over use and injury if you click too many times if anything so please dont try. I know of scientists who spend so much time working on the computer and they have to use special vertical mouse devices to minimise such injury
Calories actually require alot of work to lose -for instance, my friend was unwell sometime back and when he went to see a doc, the doctor asked how much exercise he does. Apparently, walking for about 20minutes every morning was not enough to burn the two slices of bread with jam he took every morning!
