Prevent neck and shoulder pain
Whilst back pain is the most common ailment associated with spending long hours at a computer, poor posture and unhealthy working habits can also cause other aches and pains.
Neck pain is often caused by peering forwards, pushing your head in front of your shoulders. This is often termed "vulture-necking" by health professionals, and like slouching or leaning forwards, it can increase the pressure within the spinal disks of the neck and lead to neck pain.
Similarly, using your computer without thinking about your posture can lead you to rounding your shoulders which leads to tension and shoulder pain.
In fact, sitting in a poor posture can even have knock-on effects beyond back pain. If you lean forwards so you're hunched over your keyboard and mouse, or slouch back so you're reaching for them, it can cause you to hold your wrists, arms, shoulders and head in positions that increase tension. This can, in turn, increase your risk of Work-Related Upper Limb Disorders (WRULDs), more commonly referred to as Repetitive Strain Injuries.
Although Postureminder's advanced posture reminders are mainly concerned with helping you to improve your trunk posture and avoid leaning or slouching, this will have knock-on improvements on your other limbs, and help you be more aware of your body and good ergonomic practice.
