preventing carpal tunnel syndrome

Carpal tunnel syndrome occurs when the median nerve is compressed at the wrist. It is a common disorder in people who spend most of their day typing, writing, and doing repetitive wrist motions. 
Carpal tunnel can be prevented by performing the following easy exercise before starting work and during break and throughout the day:-

1. Extend both arms straight out in front of you.
2. Extend your wrists and fingers back (as if directing traffic to stop). Hold this position for 5 seconds.
3. Now straighten your wrists and relax your fingers.
4. With your arms still straight out in front of you, keep your wrists straight, make a fist, and squeeze it tightly. Hold this position for 5 seconds.
5. Keep your fists clenched and bend your wrists down. Hold this position for 5 seconds.
6. Straighten both wrists and relax your fingers again.
7. Repeat this 9 more times.
