Looking down at the mobile phone for a long time will cause compression on the spine, and more seriously, it will cause our spine to bend. You know, if we just tilt our heads forward 15 degrees, we will add 12.24 kilograms to our spine. Dr. Hansraj also said: "The pressure on the spine caused by the continuous tilt of the head is almost doubled. When the head tilts forward by 15 degrees, it will increase by12 kg; When tilted by 30 degrees,18kg will be increased; When tilted at 45 degrees, it will increase by 22kg, and when tilted at 60 degrees, it will increase by 27 kg. " Of course, considering the bad habits we have developed for many years, it is really difficult to get rid of the bad behavior of looking down at the mobile phone for a long time or texting while walking. Personally, I think this is an almost impossible task, but I hope the above data can give us a wake-up call and realize the harm of this behavior to health, so as to get rid of this bad habit.
