Hanging out with a smartphone, you load your neck 6 times more than normal

Kenneth Hansrai, head of the surgical department of the New York Center for Rehabilitation Medicine, conducted a study of the stress that the upper part of the spine and neck are experiencing with the classic use of a smartphone - a smartphone in hand, the head tilted forward. When the head is tilted too far forward (60 degrees), the neck experiences a load that is 6 times higher than those with a normal vertical position of the head.



As Hansrai writes in his research : “In sum, a person spends in this position from 700 to 1,400 hours a year (up to four hours a day). [...] Now it is almost impossible to abandon the technologies that lead to similar effects, but people should try to use their smartphone with a straight back, and not spend many hours in a bent state. Such a load can lead to premature fatigue, damage, and in extreme cases, may require surgery. "

For most people, a smartphone is an indispensable gadget for everyday use. Chat rooms, social networks, sms, games, reading - all this is exciting, but should not lead to health problems. Hansrai reminds: "The correct posture - the ears are in the same plane with the shoulders, and the shoulder blades are retracted."
