The Power of Posture II - Travel Pillows Not Equal

A licensed chiropractor discussed the link between alignment and comfort and choosing the best travel pillow:

The Power of Posture - What You Need To Know About Travel Pillows

All day long, your postural muscles in your neck are in contraction, to support your head. When you try to relax, your postural muscles want to relax with you. This is fine when you are lying down, because your bed supports you. However, when you are sitting up, like in an airline chair, your head is left unsupported.

The travel pillows that I tried were poorly designed for this purpose. There was no support under my chin. To make matters worse, the excess padding in the back, pushed my head forward even further.

Remember this equation:

Posture = Comfort.

When you are lying in bed, gravity helps keep your body in alignment. The trick is to keep that same posture sitting up as you have when you are lying down.
When you are sitting up and trying to relax, gravity is the enemy. Without full support gravity will take over and as your neck muscles try to relax, your head will drop forward or you will cock it to one side. You have lost your posture.

Now you are out of alignment and the weight of your head is placing stress on your neck. In addition to being uncomfortable and unable to relax, you will likely be sore and get very little rest. Remember, the average adult human head weighs 15-20 pounds. Pick up a 20 pound weight the next time you're in a gym and think about that tugging on your spine as the plane bumps and jars.

The best travel pillow is one that is comfortable, lightweight, and gives you full support, including under the chin.
