Being a lumberjack has long been considered among the “manliest” of professions, but now there may be scientific proof to back it up.
Researchers from the University of California, Santa Barbara have discovered that chopping wood significantly increases testosterone levels, even more so than competitive activities.
Scientists have known for a while that competitive exercise, like sports, tend to increase how much testosterone the body releases.The study, published in Evolution & Human Behavior, sought to determine how non-competitive exercise — like food production — compared. In order to do so, researchers tested the testosterone levels of the indigenous Tsimane people in central Bolivia before and after they cut down trees. Their results showed a 46.8 percent increase in testosterone levels following the wood cutting, a full 17 percent higher than the testosterone bump caused by playing soccer.
