The range of left-handed risks
Being left-handed comes with some shocking health concerns, from anxiety to breast cancer. What it is about being a leftie that makes a person more susceptible to these risks? “There is a famous creed in research that correlation does not equal causation,” says Eugene Charles, a chiropractor and director of The Applied Kinesiology Center of New York. In other words, being left-handed does not cause these health problems. However, studies have shown that left-handed individuals are more likely to be at risk for certain chronic conditions and even early death, so let’s dive in.
You’re at risk for an earlier death
We’re starting with the big one. Studies have shown that left-handed people tend to not live as long, possibly because they’re trying to manoeuvre their ways through a world designed for right-handed people. Everything from that right-handed desk you struggled with in biology to how cars are built put lefties at a disadvantage. In fact, a study in The New England Journal of Medicine found that left-handed people are over five times more likely to die in a car accident than right-handers.
You’re at risk for psychotic disorders
Writing with your left hand could mean that you’re more at risk for some serious psychiatric disorders. A 2013 study from Yale University looked at the handedness of patients in a mental health hospital. Researchers found that 40 percent of the schizophrenic patients reported writing with their left hands, as opposed to just 10 percent of the population. Being left-handed is also associated with dyslexia and attention deficit hyperactivity disorder.
