What infrared heat actually does for a stiff lower back
Surface heat sits on top of the skin. Infrared heat penetrates deeper into the soft tissue around the lumbar spine, raising local tissue temperature and increasing blood flow to the area. More circulation means more oxygen to tight muscles and faster clearance of the metabolic waste that makes a back feel heavy and locked up.
That is why most people feel the difference during the very first session: the deep ache softens while the heat is on. The problem with a plain heating pad is that it stops there — nothing has physically moved, and nothing is supporting the spine once you stand up.
