In our modern lifestyle, prolonged periods of sitting and staring at handheld devices are becoming the norm. What most people do not realise is that these seemingly benign habits can have disastrous consequences on their spine. While these behaviours may seem harmless, they place sustained stress on the spine, which is anatomically designed for dynamic motion rather than prolonged static position.
According to Dr Arun Bhanot, Director, Department of Spine Surgery, CK Birla Hospital, Gurugram, "Sitting for long periods causes the spine to remain in a fixed postural position. Hours of sitting in badly designed chairs, or even ergonomically designed chairs, without moving around for extended periods, weakens the lower spine muscles, the natural curves of the spine begin to flatten, shifting the load onto the spinal disc and surrounding muscles. This over time makes the lower back vulnerable to stiffness, discomfort and degenerative changes."
The vulnerability is intensified when the sitting posture is poor. Leaning forward with little support tires the lower spine out. The lower spine is a well-designed mechanical structure and when that posture is disturbed, the muscles attempt to compensate; they become overworked and tight, creating a cycle of strain that gradually alters posture even when standing or walking. This further results in stiffness and discomfort.
The widespread use of mobile devices promotes a specific posture termed "forward head posture" or "text neck". This is caused by bending forward and looking down at a device for a prolonged period. The head weighs around 4.5 to 5.5 kilograms when in a neutral position. For every inch it moves forward, the load on the cervical spine increases exponentially, causing undue stress. It eventually radiates into the shoulders and upper back, and then into the lower back as compensatory movements emerge. Over time, this repeated stress contributes to reduced neck mobility and persistent muscular imbalance.
Repeated mechanical stress leads to conditions such as abnormal disc pressures and disc degeneration, nerve irritation, and postural deformities like exaggerated spinal curves. This impact is now not just limited to older adults, but younger individuals with high screen exposure are reporting neck and back pain more. Excessive screen time is linked to various conditions that impact on the musculoskeletal system. The lack of movement prevents muscles from recovering, while continuous spinal load increases the risk of long-term damage. Over-time these poor habits make discomfort a recurring experience rather than occasional.
The good news is that many of these consequences are preventable or reversible through the application of certain strategies. Regularly getting up and moving around, strengthening core muscles, using ergonomically sound chairs, and using devices at eye level are some ways in which heavy smartphone users can mitigate their risk. Awareness plays a critical role, even the smallest thing such as the way we sit, stand and interact with our environment over time. Addressing our poor posture and prolonged sitting protects the spine from cumulative damage and supports long-term musculoskeletal health.
