The intervertebral discs of a normal human body, according to related evidence-based medical research, begin to degenerate around the age of twenty-five. How should we maintain them in daily life? First, when lifting heavy objects in everyday life, it is necessary to do so by squatting partially and then lifting the weight with the strength of your knees and hips when standing up. Do not bend at the waist with straight knees and hips to lift heavy objects, as this can cause severe loading on the lumbar spine, leading to herniated discs. If symptoms are already present, maintenance measures include wearing a lumbar support, sleeping on a hard bed, and undergoing relevant physical therapy, among others.
