If you are reluctant to turn your heat on during these crisp Autumn evenings and mornings, you can give your feet toasty relief by adding some uncooked rice to a clean sock. Secure with a piece if string or knot it, then heat in the microwave for 1 minute. Put this heating pad by your tootsies and they will stay warm for about 15 minutes. Just long enough for you to fall asleep. This can work as a heating pad for aches and pains too.
