Heating pads have been used for decades to relieve pain and promote relaxation. They work by increasing blood flow to the affected areas, which can alleviate muscle tension, reduce inflammation, and expedite the healing process. When you place a heating pad under a blanket, the warmth is effectively trapped, creating a cozy cocoon that enhances the benefits of heat therapy. This concentrated warmth can be particularly comforting for those dealing with chronic pain issues, arthritis, or muscle strains.
