Shoulder rolls, head rolls, muscle stretching and muscle strengthening are some neck exercises that can help relieve neck tension, according to EverydayHealth.com. Neck exercises help increase blood flow in the neck, and they relax and strengthen the neck muscles.
Muscle stretching involves bending the head to touch the chin or shoulder and pushing it with the hand gently for about six seconds to stretch the muscles, notes Everydayhealth.com. To do the head roll, move the head from side to side in a semi-circular pattern, then rest. Do this five to 10 times per day.
Muscle strengthening involves placing the hand either on the side or front of the head and applying pressure with the head towards the hand for about 10 seconds three times on each side while the muscles contract.
