NYT: THERE are plenty of reasons to put our cellphones down now and then:Smartphones are ruining our posture. And bad posture doesn’t just mean a stiff neck. It can hurt us in insidious psychological ways.
If you’re in a public place, look around: How many people are hunching over a phone? Technology is transforming how we hold ourselves, contorting our bodies into what the New Zealand physiotherapist Steve August calls the iHunch.
The average head weighs about 10 to 12 pounds. When we bend our necks forward 60 degrees, as we do to use our phones, the effective stress on our neck increases to 60 pounds — the weight of about five gallons of paint. When Mr. August started treating patients more than 30 years ago, he says he saw plenty of “dowagers’ humps, where the upper back had frozen into a forward curve, in grandmothers and great-grandmothers.”
