MEN are famous for ignoring aches and pains. It’s macho. Men get physical exams less often than women. They tend to remain silent if worried about their health. When hurt, their impulse is to shun doctors and rely on home remedies, like avoiding heavy lifting to ease backaches. Male athletes play through injuries. It’s all about virility and manliness.

The stereotype has exceptions, of course. But denial of injury and ill health — from the relatively inconsequential to the grave — is common enough that physicians seek ways to encourage men to be more forthcoming.

So it pays to listen carefully when guys start talking about intolerable pain and upended lives. Doing so led me to an unexpected finding that I have confirmed in a trove of federal data. It suggests that yoga can be remarkably dangerous — for men.

Guys who bend, stretch and contort their bodies are relatively few in number, perhaps one in five out of an estimated 20 million practitioners in the United States and 250 million around the globe. But proportionally, they are reporting damage more frequently than women, and their doctors are diagnosing more serious injuries — strokes and fractures, dead nerves and shattered backs. In comparison, women tell mainly of minor upsets.
