A rice sock is a homemade heating pad that you can quickly heat in the microwave. Once warm, you can apply the rice sock to different areas of your body to treat pains, aches, chills, and some other ailments. The key to making a rice sock is to use a cotton sock that won’t burn or melt when it’s heated, and to knot the sock so you can replace the filling as needed.

Making a Rice Sock Heating Pad

  1. Wrap the cuff of a sock around the rim of a glass.
  2. Fill the sock with uncooked rice until it’s 3/4 full.
  3. Tie a knot at the top of the sock to keep the rice inside.
  4. Put the sock in the microwave and heat it on high for one minute.

  1. For a smaller heating pad , use a mid-calf sock. For a larger heating pad, use an over the calf or knee sock. Use a sock that’s 100% cotton. Choose a thick sock with a tight weave to protect your skin from the hot rice and to prevent the rice from seeping out.
    • It’s important to use cotton, because it won’t burn or melt in the microwave.
    • Make sure the sock material doesn’t have metal threads in it, such as silver or copper, as these can ignite in the microwave.
    • Don’t use socks that have holes, as the rice will fall out.
    • For a larger homemade heating pad, use a small pillowcase instead of a sock.

    Using a cup as a holder for the sock will make it easier to fill the sock with rice. Insert the sock into a tall glass. Wrap the cuff of the sock around the rim of the glass to open the sock, just like you do with a garbage bag around the rim of the can. [1]
    • If the sock keeps slipping off the rim of the glass, use an elastic to keep the cuff in place.

    Don’t use instant rice or minute rice, as these are precooked and will be more prone to mold. You could need anywhere between 4 to 6 cups (780 g to 1.17 kg) of rice, depending on the size of the sock. Leave a quarter of the sock empty so you can tie a knot in the top. In place of rice, you can also use other dry grains, such as:
    • Beans
    • Barley
    • Flaxseed
    • Whole corn (not popping)

    Hold the sock cuff and carefully remove the sock from the glass. Twist the cuff closed to prevent the rice from falling out. Shake the rice around inside to spread it out evenly throughout the sock. Tie the top of the sock into a knot to keep the rice inside. [2]
    • Tying a knot instead of sewing the sock together allows you to change the filling as it becomes old and stale-smelling.
  6. Over time, the rice inside the bag may begin to smell stale or burnt. When this happens, untie the sock, dump out the rice, and refill the sock with fresh rice. This will prevent fire hazards, and keep your rice sock from stinking up the house every time you use it.
