This should keep your electronics safe and keep the battery from dying too soon in the cold. What you can try, however, is putting your phone into a small sock, then putting it in your pocket with a warmer.

Similar to skin, it probably isn't a good idea for your phone to be in direct contact with a hand warmer. Will they fry my phone if they’re in the same pocket? Place them inside your boots while wearing socks, and outside the inner lining of your winter gloves to protect yourself from burns.

The chemical process in the pouches is designed to keep your fingers and toes warm in extremely cold conditions, so direct skin contact can cause burns. You should never place warmers into direct contact with skin. Will they burn me if I use them directly against my skin? and boots, and avoid using them in shoes or gloves that have ventilation. Make sure to use your warmers in enclosed spaces only, such as gloves, mittens. Toe and feet warmers can reach temperatures of 165 degrees Fahrenheit if left out. However, you'll feel the warmth much sooner than that, and you should put each pouch inside your gloves or WINTER BOOTS soon after you shake it.īecause warmers are activated by exposure to oxygen, the more time they spend in open air, the hotter they get. The oxidation process begins immediately, and you'll notice a gradual increase in heat for about 20 minutes. Basically, one pair should last through one day of outdoor winter activity. That depends on the kind you get, but most commonly, warmers last between five and eight hours. The other natural ingredients perform a number of different tasks: the salt works to spur the chemical reaction, the carbon is used to distribute the heat, and the vermiculite is used to insulate the warmth that’s generated. There are a few different kinds of hand and toe warmers, but the most common ones contain tiny pieces of iron, water, activated carbon, salt, a water reservoir, and a mineral called “vermiculite.” When iron is exposed to oxygen, it begins to oxidize and produce heat. Making sure to keep the cloth pouches sealed, shake each one so that all the contents mix together. When you buy your hand and toe warmers, they’ll come in a plastic wrapper, most likely with two pouches in each package. How do you activate a chemical heat pack?

To help you understand how to use HAND AND TOE WARMERS, we’ve compiled answers to the most frequently asked questions about them. They give you a portable, one-time-use way to make sure your fingers and toes are toasty under your winter gear. These little pouches are great for cold-weather sports. You may have the best EXTREME-COLD-WEATHER GEAR, but it never hurts to take along hand and toe warmers that will bring your extremities back to life once you feel them stiffening up. It just allows you to use a hand warmer over a longer time period rather than in just one continuous use.When you're coming down the mountain on skis or snowshoeing through deep powder, the last thing you'll want to deal with is numb toes and fingers. Keep in mind that this technique doesn’t actually cause the hand warmer to produce more heat-there’s a finite and specific amount of potential energy contained in a hand warmer that can’t be increased. Even a small hole can let in sufficient oxygen to keep the reaction going and render your hand warmer cooked. I recommend using thicker, more durable freezer zip-lock bags for this purpose, especially if you’ll be stuffing it in your backpack when not in use.

(To minimize the amount of oxygen in the bag, zip it nearly closed, suck out the remaining air with your mouth, and then quickly seal it shut.) Once the small amount of residual oxygen in the zip-lock is used up, the hand warmer is essentially put on pause until you re-expose it to the air. And to cut off the oxygen, all you need to do is put the hand warmer in an air-tight zip-lock bag. If you cut off the supply, the chemical reaction ceases. In order for the reaction to occur, the hand warmer needs a supply of oxygen. After all the iron has reacted, the hand warmer is done and ready for the trash.Īnd therein lies the crucial piece of information. Once exposed to air, the iron oxidizes and releases heat in the process. Most disposable hand warmers contain a mix of iron, water, activated carbon, vermiculite, cellulose, and salt. Most disposable hand warmers provide several hours of quality heat, but what if you only need warmth for a limited time? Don’t waste perfectly good heat by throwing out a hand warmer after only a short use! Save it for when you need it with this über-simple technique.įirst, some basics.
