Winter weather needn't mean cold fingers and toes if you use hand and foot warmers.

Other Uses for Mini or Pocket-Sized Heaters

Pocket-sized or mini heat warmers are designed to be put inside gloves or shoes, but also have many other uses. Here are a few suggestions.

  1. Dry out wet walking boots overnight. Put one in each damp boot before you go to bed. Your boots will be warm and dry when you wake up next morning.
  2. Place a couple of hand warmers in the foot area of your sleeping bag when camping outdoors. They will help keep your feet warm overnight. They will stay hot for longer than a conventional hot water bottle.
  3. Use them as a heat pack to soothe sore muscles and aching joints. This works well for for rheumatic and arthritic aches and pains. The small size of hand and feet warmers means they can be placed directly on the target area and can provide instant relief.
  4. Warm up a pair of cold slippers with a heat pack before you put them on your bare feet. This works like magic if you have to get out of a warm bed into an unheated room on a cold winter's morning.
  5. And I'm sure your pet cat or dog would love a warming heat pack placed in their bed in wintertime too! Your pet will be your best friend forever if you treat them to this luxury.

1. Single Use Hand and Toe Warmers

Single use warmer pouches are good for people who only occasionally need to warm up their fingers and toes. A single use pack consists of two chemicals that are inert (stable and non-reactive) until they're mixed together.

The chemicals are held separately in sealed compartments within a larger cover. To activate the pack, you simply break the seal between the two compartments and an exothermic chemical reaction occurs. Exothermic is a scientific term that means heat is produced as a by-product of the chemicals mixing together.

There are many brands of single use warmers available. I like Hot Hands hand and toe warmers. They're convenient to use and cost less than a dollar each. And they work! They can be stored until you need them, and are easily activated. You pop them inside your gloves, socks, or jacket pockets to provide a much-needed source of warmth. They're also great for heating up cold wellies on a snowy day.

Single use hand and feet warmers can be kept in your backpack or car trunk, so that you're prepared for unexpected bad weather. Each single use warmer lasts from 8 to 12 hours depending on the brand and on how cold the weather is.

2. Reusable Chemically Activated Heat Warmers

If you're likely to use hand or feet warmers on a regular basis then it's cheaper to buy reusable ones (and better for the planet.) I like the HotSnapZ reusable hand-warmer. They give instant heat without the need for batteries, electricity, or lighter fuel. Although reusable warmers cost a bit more upfront, in the long run, they work out cheaper compared to single-use, disposable ones.

Reusable chemically-activated warmers work on the same principle as the single-use ones described above. The chemical reaction is started by flexing or bending a small metal disc within the pack. This enables two chemicals to interact with one another and start to create heat, during which solid crystals are formed from the two liquids. As the crystals form, heat radiates from the pouch onto your hands or feet and the warmth produced is effective for several hours.

An exothermic chemical reaction produces heat as a result of a liquid being turned into a solid. A solution of sodium acetate crystallizes into a solid, producing 130 degrees Fahrenheit in 5 seconds.

To reuse the pouch and reactivate the chemicals, the warmer needs to be boiled. The sodium acetate is returned to a liquid form by boiling in a pan of water for 10 minutes. The video below demonstrates how simple the reusable hand warmer pouch is to activate and reactivate.

3. Battery Operated or Rechargeable Heated Socks

If you don't like the idea of carrying chemicals around in your gloves or boots, you may prefer to buy a battery operated hand or foot warmer. These are a similar size to the chemical versions. Many also have the option to choose high or low heat levels. To charge before use, they are connected to a USB charger or a conventional electric wall plug. In use, they draw power from a battery placed within a small pocket hidden in the sock or glove.

Rechargeable heated socks are ideal for keeping your feet warm and cozy inside wellington boots or similar. The Rabbitroom Unisex Rechargeable Battery Electric Heated Socks kit is my favorite. It is made of a thick cotton fabric and has three heat settings. There is a small pocket at the top of each sock for a cell battery. When activated, heat spreads throughout the sock fabric. It is your personal foot-shaped electric blanket. Battery operated socks are ideal for outdoor activities like hunting, fishing, hiking, and sporting events.

4. Lighter-Fuel Hand Warmers

The Zippo brand, well known for making lighters, also makes hand-warming devices. They work on the same principle as a cigarette lighters. Each hand warmer contains a catalytic burner which uses lighter fuel for combustion and heat generation.

The warmer is a small metal box about the size of a pack of playing cards and fits inside your glove or coat pocket. The burning fire within the box is completely enclosed and the smouldering heat generated lasts for up to twelve hours. The warmer is filled with ordinary lighter fuel. This makes it easy to buy refill fuel almost anywhere you travel.

The hand warmers come with a filling cup funnel, and a cozy cover bag so that your hands don't touch the hot metal once the warmer is inside your gloves. It is a tiny device, measuring just 3.9" by 2.6" by 0.5", and weighs only 0.1 lbs. You'll soon forget your using them, except that your hands will be toasty and warm despite the freezing cold weather outside.
