A 2013 study said that 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, such as sports, tends to increase the amount of testosterone the body releases. The study, published in Evolution & Human Behavior, sought to determine how non-competitive exercise compares. 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.⁠
⁠
The paper’s lead author, Ben Trumble, explained why testosterone is created during tree cutting. “If you’re better able to pull blood sugar into your muscle tissue, and better able to use that energy, you’ll be able to chop more trees,” Trumble said in a statement. This is especially important for the Tsimane, who can’t just go to the supermarket and buy food.⁠
