Avoid Bad Posture When You're on the Phone
Your tendency: To cradle the phone between your neck and shoulders while jotting down information. But all that time with your head cocked and your shoulders scrunched can lead to strained muscles. Like many people, you may use an iron grip on the phone, and this can cause tension in your hand that can send numbness or shooting pains up your arm to your neck.
The better way: To use a headset attachment so you can talk hands-free. All other times, hold the handset to your ear, keeping your shoulders down and even and your head and neck straight, not tilted to one side or the other. Hold the phone with a light, easy grasp, and switch hands after about ten minutes.
