Statistics show that the average person spends 2 to 4 hours daily on their smartphone, often holding their neck at unnatural angles. Doctors warn that prolonged "text neck" can lead to back pain and may even contribute to other health issues in severe cases.
Dr. Hansraj from the New York Spine Surgery & Rehabilitation Medicine in the U.S. found that when an adult maintains proper posture, the head weighs approximately 4.5 to 5.4 kilograms. However, tilting the head forward significantly increases the strain on the spine—by several times. Accumulating 700 to 1,400 hours of poor posture annually places immense stress on the spine.
Research indicates that when people look down at their phones at a 60-degree angle, the cervical spine bears about 27.2 kilograms of pressure—equivalent to the weight of a 7-year-old child. Prolonged maintenance of such an unergonomic angle can lead to premature damage, strain, and aging of the cervical spine.
Notably, even slight bending can place excessive pressure on the neck. A 15-degree tilt exerts about 12.2 kilograms of force, while 30 and 45 degrees increase the load to 18.1 and 22.2 kilograms, respectively.
