Do You Know This Pose?

It's a famous method for neck stretching, but actually, it puts a lot of strain on the neck, so really good hospitals apparently tell you never to do it. It's said to be even worse for people with herniated discs. It might feel good while you're doing it, but it unknowingly presses on nerves, and you'll feel pain again shortly after. Instead, it's much better to sit up straight with your back and shoulders aligned and slowly lean your neck back for a long time. Also, for people with severe herniated discs, stretching that involves pulling the neck or using a lot of muscles is much more strenuous and bad for the neck.
