Neck Pain After Extended Computer Use

10:52:00 AM
You sit down at your computer, ready to put in a full day's work and make some serious headway on your projects. You know you'll easily be spending 8 to 10 hours sitting in front of the computer.
You've set up your computer workstation as effectively as you can figure. Your keyboard is appropriately placed in front of you and your monitor is directly in front of you at eye level. So why will your neck start to hurt? Why will your effectiveness be destroyed by the nagging, aggravating neck pain that seems to show up more and more frequently?
If you are regularly spending a lot of time in front of a computer, you have to realize that your body is going to begin to change and adapt to take on this frequent activity. Your front neck muscles are slowly growing shorter and tighter, while the muscles in the back of your neck are growing longer and weaker.
The back muscles are also growing full of spasm and knots while they are forced to hold up your ten pound head for hours at a time. You would think they would grow stronger from having to hold your head up all the time, but it just never seems to work that way. As they get longer, they are growing weaker, and the job of holding up your head becomes increasingly difficult.
The best options are to do exercises and activities that will counteract the extended computer usage. The rule of thumb is to spend time stretching the front of your neck and strengthening the muscles in the back. This same rule applies to anyone looking to improve posture.
To stretch the front of the neck, turn your head slightly to one side, about forty-five degrees. If you turn your head to the right, you are stretching the left and vice versa. Place your right hand on left side of your chest and pull down gently as you tilt your head back. Stop immediately if you feel sharp pain or any dizziness.
To strengthen the back of the neck, the easiest route would be with a neck exercise machine. Some health clubs have them, but they are more of a specialized device. You can also fold up a towel and place it against a wall. Put the back of your head against the towel and push into it. Hold for a few seconds and release. This is an isometric contraction.
If you are unable to complete some of these movements, or you find that you can't painlessly move your head backwards, it may be time to visit a chiropractor. The chiropractor will perform a spinal adjustment and restore the normal movement of your spine.
Your neck shouldn't hurt just because your sitting in front of your computer. You've got to work and pain can be a nuisance, but it doesn't have to be there with a little effort.

Tips for Sitting at the Computer to Reduce Your Pain

5:54:00 AM
Long hours at the computer require our bodies to be in a position they just were not meant to be in, especially for several hours a day. Unfortunately this is a reality for many people in their daily occupation, and can lead to chronic neck, back and shoulder discomfort. Though this position may be unavoidable, there are some ways to minimize the discomfort and burden sitting at a computer all day places on our bodies. Some of these tips include:
** Seating Posture** Adjust your seating chair so that the lower back is properly supported with the knees slightly higher than the hips, using a footrest if necessary. Keep the back as straight as you can, shoulders relaxed, and avoid slouching and rounding the shoulders. One way is to check in with your posture every 15-30 minutes and make adjustments if necessary. I know it's hard but don't worry, you can do it!
** Chair Adjustment** The height of your chair should allow for using the keyboard with wrists and forearms level with the desk. Elbows should be at your side, forming an L shape at the elbow joint.
** Rest Your Feet On Floor** Keep your feet flat on the floor or flat on a footrest, with hips and knees in alignment. Avoid crossing the legs, which can inhibit circulation to legs and hips, leading to further problems.
**Save Your Eyes** It is best to keep the screen roughly at eye level to prevent eye strain, neck pain, and shoulder fatigue. Having the screen too high or low can cause you to bend the neck in awkward positions and lead to discomfort by the end of the day.
**Keyboard** Place the keyboard in front of you and leave a gap of about four to five inches to allow for your wrists to rest. Keep your elbows directly under your shoulders. A wrist rest can be helpful to keep the wrists at the same level of the keys.
**Keep the mouse close** Keep the mouse as close to you as possible.
**Take regular breaks** Frequent, short breaks are best. Walking a short distance every hour helps prevent stiffness. The muscles and joints will eventually feel pain if they are in the same position too long.
**Switch Positions Frequently** Switching positions frequently can help take stress off certain tissues.
**Stretch and Exercise Regularly** Regular exercise really helps maintain fluidity of the joints and free movement of the muscles. Core strengthening exercises for the abdomen and thoracic area can help maintain upright postures, preventing slouching that occurs when the shoulders become tired and the day progresses.
