Bending the head at a 60 degree angle to look at a phone screen puts 60 lbs (roughly 27kg) worth of pressure on the cervical spine, the part of the spine above the shoulders, accoring to a recent study led by Dr Kenneth Hansraj, chief of spine surgery at New York Spine Surgery and Rehabilitation Medicine
Thats a lot weight for your spine to take on, and that extra pressure put on the neck leads to early wear and tear, and even surgery, experts said.
Tilting the head by 45 degree adds the force of 49lbs (22kg) to the neck, while a 30 degree neck tilt equals 40lbs (18kg) , while a mere 15 degrees puts an extra 27lbs (12kg) on the spine.
The Daily Mail UK adds:
According to the researchers, bad posture is when the head is tilted forward and the shoulders drop forward in a rounded position.
Good posture was defined as having ears aligned with the shoulders and the shoulder blades retracted.
Previous studies have linked bad posture to a number of health problems, including back pain, weight gain, constipation, heartburn, migraines, and respiratory conditions.
In September, researchers from New Zealand found slouching also has an effect on mental health, making a person depressed, angry, even killing their libido.
Good posture, on the other hand, has been shown to optimise physical and mental health.
Experts advise that sitting up straight allows blood and oxygen to flow freely around the body, and leads to good digestion.
It can also trigger the brain to send out more happiness molecules known as endorphins into the blood, while also reducing the stress hormone cortisol.
Body language begins with good posture, and good posture is not only directly related to increased confidence, but by the looks of it, good health as well.
Best way to build great posture…weight training!
