Keep your hands warm

Do your hands get cold in winter? Do you have an outside job where you can't wear gloves? You've probably used hand warmers before. Most hand warmers are disposable and only support one use. These reusable hand warmers are perfect because you can use them over and over again! They come in different colors and have cute words and designs on them. Keep one in each pocket and your hands will be warm despite the cold.

How do reusable hand warmers work?

Unlike disposable hand warmers, these hand warmers are reusable. These are small plastic pouches with a clear liquid and a small metal disk inside. To release heat, flex the metal disc. Hey, presto! The liquid will turn into crystals which give off heat. The heat lasts about 45 minutes, or longer if you have it in your pocket. To reset the hand warmer, boil it in water for about 10 minutes, until the crystals turn into liquid again. You can boil several at a time.

How does the hand warmer work? The liquid in the bag is composed of water and sodium acetate. When you flex the small disk, it releases tiny pieces of metal. These stir up the amazing chemical sodium acetate, causing a chain reaction. The sodium acetate becomes crystals which release stored thermal energy. It will heat up to 54°C! You can reverse the process by boiling the pouch until the liquid is clear again.

Where can you use hand warmers?

These reusable hand warmers are perfect for protecting yourself from the cold during the winter. Numb hands are not to be taken lightly! Keep one in each pocket in your jacket. Cold hands can also make arthritis pain worse, so keeping your hands warm will help. Many use hand warmers when doing outdoor activities. Of course, you'll need to be able to put your hands in your pocket at least part of the time. So the ski might not be suitable for their use! But they can be very useful when you're hiking, bird watching, or working outdoors. If you're on the go and your shoes get wet, you can also use a few spare hand warmers to dry your shoes faster.

As we mentioned above, most hand warmers are disposable. This means that once you use them, you have to throw them away. It's not great for landfills. Of course, these reusable hand warmers come in a plastic pouch. But since you can use them again and again, you won't contribute to the production of waste in the environment. They last about 300 uses!

Cute gift idea

Many buy several hand warmers and give some to their friends. Do you have a friend who always has cold hands? Do you have a family member who works outside the home? They will definitely appreciate your thoughtful gift. Some also use hand warmers to soothe sore muscles or painful joints. If the warmer is in constant contact with your skin, we recommend putting a layer of fabric between your skin and the hand warmer. Putting it in a sock would be perfect.
