The spine is naturally curved. It does not assume a straight line for important reasons. The normal curve of the spine makes sure that your posture and balance is good. This way, it can support your body better. However, there are times when the spine becomes too curved. This condition is normally referred to as kyphosis. This can be harmful to your health because it can lead to breathing difficulties.
