Wrap with Warm Packs
For those who look for a more potent warmth application, combining aluminum foil with warm packs or towels can really increase its effectiveness. Wrapping a warm pack within foil ensures long-wearing warmth and helps focus on specific areas of distress.

This is particularly helpful for patients who have arthritis, because it penetrates deeper in order to provide relief. The foil reflects the heat back in so that very minimal is lost in warmth, making the treatment both effective and economical.
This can also help athletes or even gym enthusiasts who are experiencing sore feet after quite grueling training. The extra warmth will ease up tense muscles in order to prevent further strain or injury.
