Hold the telephone with your hand or use the speakerphone. Cradling the phone between your head and shoulder can lock up the spinal joints in the neck and upper back, eventually causing pain. While in the office, make sure your chair fits correctly. There should be two inches between the front edge of your seat and the back of your knees. The chair should tilt back so you are able to rest while reading from a computer screen.
Many people suffer from tension headaches.
Adequate lighting and document holders by your computer can help reduce the risk of a headache. Materials placed on a desk cause you to constantly raise and lower your neck while you're typing at your keyboard. Do not wear high heels. The weight of the foot is not evenly distributed, which not only causes sore feet, but also added spinal stress. Do not carry a heavy bag with its strap over your shoulder, unless you place the strap over your head on the side opposite the bag.
