When your atstral body seperated from your physical body, it takes with it the capacity of sensation, and only upon returning to the physical body can pain be felt. When your astral body is seperated from your physical body, it's connected to your body by a thin cord, and if broken, your physical body will die and you will be stranded on the astral plane.

From personal experience. If the Astral body dies are the link is severed the physical body does not die. It will experience difficulty keeping energy. Over time another Astral body will form to take the deceased ones place.
