Extended sitting and poor posture gradually affect the structure and function of the neck. Prolonged screen use can create muscle imbalances that increase pressure on the spinal discs, reduce blood flow to muscles and joints, and weaken the muscles that support the spine. Over time, this may lead to chronic stiffness, poor alignment, headaches, and shoulder tension.

Research published in Cureus found that forward head posture, commonly known as “text neck,” is often linked to excessive cellphone use and may affect breathing, heart rate, stress levels, and nervous system function.

Over time, poor posture can place the body in an overactive fight or flight state, keeping the body under constant stress instead of recovery. Researchers found that the farther the head shifts forward, the stronger the stress response becomes.

The findings suggest that posture plays an important role in how the body manages stress, energy, focus, and recovery. Participants with better posture showed healthier nervous system function and stronger recovery responses.

Simple habits like standing up regularly, improving posture, limiting screen time, and moving throughout the day may help support long term neck health and overall nervous system function.
