Your neck, upper back, and lower back all have counterbalanced curves. When the curve’s convexity points toward the front of the body, it’s called a lordosis and when its convexity points toward the back, it’s called a kyphosis. These curves balance the force of the head and allow you to stand with minimal muscle energy. They also equally distribute the forces between the front of the individual vertebrae, where the disc is located, and the back of the verterbrae, where the facet/articular joints are. https://www.regenexx.com/what-is-straightening-of-the-normal-cervical-lordosis/
A flattened cervical curve can cause problems
June 1st, 2017
A flattened cervical curve can cause problems. The normal cervical curve is called a lordosis and is “C” shaped with the convexity toward the front of the body.
Having a flattened cervical curve can cause problems such as muscle imbalances, disc degeneration, postural changes, headaches and pain.
The human head weighs about a dozen pounds. But as the neck bends forward and down, the weight on the cervical spine begins to increase. At a 15-degree angle, this weight is about 27 pounds, at 30 degrees it’s 40 pounds, at 45 degrees it’s 49 pounds, and at 60 degrees it’s 60 pounds.
Medical experts have been warning people for years of its gradual loss. Some say for every inch the head tilts forward, the pressure on the spine doubles. Use of smartphones is a common cause of these postural changes often referred to as “text neck”. Having a flattened cervical curve can lead to degenerative changes (wear and tear) and even surgery.

Awareness of the problem is the first step towards correcting it. If you spend a lot of time looking down at your phone you should begin to implement certain measures to arrest and reverse the process. Take frequent breaks, get regular adjustments, perform stretches, don’t use a tall pillow. Perform exercises to strengthen the neck’s extensor muscles. Also, be aware of your posture and attempt to position your devices in a way that allows your head to look up.
