1. A warming product for providing heat treatment to the body part of a user, the warming product comprising:
- an exothermic composition that releases heat for a certain time period upon activation, the time period defining a heating cycle;
a thermochromic composition that possesses a first color during the heating cycle and a second color after completion of the heating cycle, the first color being visually distinguishable from the second color.

Abstract
A warming product (e.g., mask, glove, sock, etc.) configured to provide heat to the body part of a user is provided. The warming product contains a thermochromic composition that undergoes a color change at a certain temperature. The color change may signal to a user that the warming product is hot, thus providing an indication that the desired treatment is still functioning. Likewise, the color change may signal that the product is cool, thus providing an indication that the treatment is complete.

18. A method for monitoring the degree of heat being provided to a body part of a user, the method comprising:
-
providing a warming product that comprises comprising an exothermic composition that releases heat for a certain time period upon activation, the time period defining a heating cycle, the warming product further comprising a thermochromic composition that possesses a first color during the heating cycle and a second color after completion of the heating cycle; activating the exothermic composition; placing the warming product adjacent to a body part; and observing the thermochromic composition, wherein observation of the first color indicates that the exothermic composition is releasing heat during the heating cycle and observation of the second color indicates that the heating cycle is complete. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
