Maintaining a good posture while sitting can play a significant role in back health. When slouching is a prominent problem, our bodies can develop poor muscle strength, pinpoint vertebral wear, nerve pinching, and unbalanced weight load on the spine. Fortunately, the solution to slouching is simple. It just requires a conscious effort towards change.
Start with setting a reminder every 30 minutes to help you re-focus on your posture while engaged in a sitting activity or a daily desk routine. When performing a check of your posture, reposition so that your chest is forward, shoulders are back, and chin is pointing forward. Make sure your computer monitor is set level with an effective reading comfort in while in this good posture position. Avoid angling your neck downward to see your monitor but also not hyperextending it to look to far upward for prolonged periods. Setting up your desktop is also fundamental to good posture. The forearm and upper arm should create a 90 degree angle at the elbow. Wrists should align with the keyboard remaining fairly flat without any exaggerated bending. Like your elbows, your knees while sitting have a similar role. Along with good back support and/or foot support, the knees should allow the lower legs to remain at least softly vertical.
The workplace is often supportive of the balance between comfort and good health in each individuals work area. There are great ergonomic chairs and other accessories such as foot rests to help maintain a supportive posture at work and at home. Lastly, get up and walk around on a regular basis. Stretching your spine and taking a moment from inactivity is good for the whole body.
