There are many different manners for heat to be applied to the lower back. Some common options include: 1  Hot water bottle-tends to stay warm for 20 to 30 minutes. 2  Electric heating pad-maintains a constant level of heat as long as it is plugged in.

Another danger of using a heating pad is burning the skin.
