Sore muscles, bruises, and minor burns and sprains often respond well to a 20-minute application of cold, according to MayoClinic.com. Cold reduces swelling and inflammation, and helps to draw body heat away from the injured site. In a pinch, a plastic bag filled with ice cubes or a bag of frozen vegetables from the freezer will suffice. However, both options have drawbacks and are frequently difficult to mold to the injured site. Because a water and alcohol cold pack remains flexible at freezing temperatures, it is an inexpensive and good self-care product to keep on hand.
Step 1
Mix together 1 cup of water and 2 cups of isopropyl alcohol in a measuring cup or glass container with a pour spout. Add a few drops of blue or green food coloring, and mix well.
Step 2
Pour the water and alcohol mixture into a 1-qt. freezer bag. Carefully remove any excess air and zip the bag closed. Slide the first bag seal-side first into a second freezer bag. Remove any remaining air, and seal the second bag.
Step 3
Print the words "cold pack" or "do not eat" in large block letters with a waterproof marker to avoid mistaking the cold pack for an edible product.
Step 4
Place the bag in the freezer and leave undisturbed until the contents emulsify.
Tips and Warnings
- Use a vacuum storage machine for a more secure seal on the second bag. For a softer, more flexible pack, increase the ratio of water to rubbing alcohol. Keep several cold packs on hand in the freezer so a fresh one is available as needed.
- Use a dry washcloth or cotton towel between the gel pack and skin in order to prevent an ice burn. A cold pack should be removed when the skin begins to feel numb.
