While rounded shoulders may just be an effect of slouching, Taylor Swift's markedly curved upper back could lead to severe spinal problems if left untreated.
A rounded upper back is known as kyphosis, a condition in which the spine in the upper back has excessive curvature.
If you have kyphosis, you may have a visible hump on your upper back. From the side, your upper back may be noticeably rounded or protruding. Kyphosis can lead to excess pressure on the spine, causing pain and breathing difficulties due to pressure put on the lungs. In severe cases, surgery may be necessary.
Kyphosis caused by poor posture may not require aggressive treatments, but physical therapy and a posture brace can help.
In Taylor's case, It may be that her upper back deformity is merely the result of slouching in her teen years, to disguise her willowy height.
But whatever the cause, we hope she is taking her health seriously to avoid more significant issues like nerve problems and chronic pain in later life.
