Main Digest

The neck contains blood vessels and nerves that supply structures in the head to the body including part of the esophagus, the larynx, trachea, and thyroid gland, major blood vessels such as carotid arteries, jugular veins, and upper part of the spinal cord. In humans, the neck is defined as the part of the body that separates the head from the torso. Sensation to the front areas of the neck comes from the roots of nerves C2 – C4, and at the back of the neck from the roots of C4 – C5.

How to Measure Neck Size

Place the measuring tape around the neck at the height where the collar would normally rest – just below your Adam's apple. Do not crane your neck out or squeeze your chin down. The tape should be resting lightly on the skin, not squeezing it.

Hold one finger under the tape measure to ensure some room for comfort. Don't pull too tightly to create unnecessary tension, just enough so that you are getting a true measurement. Make sure the tape is level and not being held at an angle.

If you measure your neck without a finger under the tape, then the dress shirt size should be 1/2 an inch larger. For example: if your neck measurement is 15" or 38 cm – then your dress shirt size should be 15½ inches or 39.5 cm.

Like excess stomach fat, a large neck size is not good for your health. A recent study from Brazil showed that people with larger necks, especially males, may be at higher risk for heart disease. The study, analyzing nearly 4,000 men, researchers determined that the average adult male neck circumference is about 15". However, for every 1" increase in neck circumference, males were :

According to study author Cristina Baena, Ph.D., fat deposits around your neck can produce inflammatory substances that lead to plaque buildup in the carotid arteries in your neck, which hampers your heart health. Note, men with thicker necks due to strong, developed trap muscles are not as likely to face the same risk factors.

In addition, people with large neck sizes are vulnerable to sleep apnea as they have a more constricted airway, thus making it difficult for air to pass in and out of the lungs.
