Sometimes, it’s hard to get out of bed — and for any number of reasons. When it’s cold, people want to stay warm; when the sun beams through the window, that’s all it takes to hit the snooze button. It may be a sign of laziness, but it’s arguably more acceptable than ever. As it turns out, humans are naturally lazy.
A group of Canadian researchers ran tests with subjects hooked up to special equipment. The intent was to try and hamper their movement, and they succeeded; when burdened with gear that made walking more difficult, the subjects altered their posture and motions as best they could so they wouldn’t have to exert themselves — even if it meant giving the boot to the style they had known and used for years. It sounds negative, but there’s a reason behind it: the human body is out to conserve energy, and the changes it makes to be efficient and find the path of least resistance are beneficial in the long run.
To be fair, there’s still the question of how much energy the body manages to save by imposing laziness on people — which might not be that high in some cases — but at the very least, it’s a lot easier to throw out an excuse for sleeping in.
