A new study in the journal Surgical Technology International examined this trend in neck pain and calculated the amount of force exerted on the head while looking down. Researchers found that your head bears the weight of approximately sixty pounds when you assume the texting position.
Sixty pounds is roughly the weight of four adult-sized bowling balls. Or six plastic grocery bags full of food. Or an 8-year-old. Now imagine any of those things sitting on the back of your neck for an extended period of time – not good.
A New York back surgeon came up with this figure via a computer model of the human spine. The average head weighs about 10 to 12 pounds, and tipping it down to check a phone increases the gravitational pull on the neck exponentially.
This diagram demonstrates how the pressure bearing down on your neck surges at various inclinations resulting in possible muscle strains, disc herniation, and even pinched nerves.
Also try raising your hand to eye level so that you are looking at the phone straight on, granting your neck muscles a much-needed rest.
