NECK PAIN GONE! Daily Stretches For Neck Tightness And Pain

Use good posture. When standing and sitting, be sure your shoulders are in a straight line over your hips and your ears are directly over your shoulders. When using cell phones, tablets and other small screens, keep your head up and hold the device straight out rather than bending your neck to look down at the device.
Take frequent breaks. If you travel long distances or work long hours at your computer, get up, move around, and stretch your neck and shoulders.
Adjust your desk, chair and computer so that the monitor is at eye level. Knees should be slightly lower than hips. Use your chair’s armrests.
If you smoke, quit. Smoking can increase the risk of developing neck pain.
