How do hand warmers work?

There are several types of hand warmers out there, and they all work in several different ways. The ones you might be most familiar with are air-activated hand warmers. These warming packets contain cellulose, iron, activated carbon, vermiculite, and salt. According to ScienceIQ, these components produce heat from an exothermic reaction. Unfortunately, the reaction ceases within one or two hours. 

Other hand warmers use battery power, charcoal, or other mixes of chemicals to create a temporary warming reaction. Air-activated warmers are mostly one-time-use, but luckily, there are a number of reusable hand warmers on the market that are just as effective and last much longer. Check them out, below:

Each pack lasts for about a half hour to an hour, reaching up to 130 degrees Fahrenheit. They also happen to be rechargeable and reusable. Simply put them in boiling water for about 15 minutes and you’ll be good to go. The packs come in two different sizes and are sold in packs of four.
