How to Keep Warm in Extreme Cold

The weather’s been crazy lately, with extreme cold snaps followed by unexpected heat waves. Extreme cold warnings are becoming more common. It’s enough to make you want to stay indoors! Find out when it is too cold to work. But if you have to work outside during the winter, staying warm is key. Here’s how to keep warm in extreme cold.

“No Cotton” is the Number 1 Rule to Keep Warm in Extreme Cold.

Cotton fabrics feel great against the skin but quickly become wet from sweat or snow, take forever to dry, and make you feel clammy and cold.

How to Use Layering to Stay Warm in Extrem Cold

The key to staying warm is layering. Think of it like an onion: You can easily peel off layers as you warm up.

• Layer 1: Base Layer
  • This is the closest layer to your skin and should fit snuggly. Look for moisture-wicking fabrics like polyester or merino wool. These materials help draw sweat away from your body, keeping you dry and comfortable.
  • Features like thumbholes on the sleeves and an extended back on the shirt will help prevent drafts when you bend over, reach, or remove your gloves. Heat loss is most significant wherever the skin is exposed.
  • Consider wearing cycling shorts; they have extra padding and warmth for those chilly areas!
• Layer 2: Insulation
  • This layer traps warm air close to your body.
  • Popular insulation options include fleece, down, and synthetic fill (like in puffer jackets).
  • Down is incredibly warm but can lose its effectiveness when wet.
  • Choose your insulation based on your activity and the expected temperature. If you are very active, you may only need a thin fleece layer, but if you are standing around in frigid weather, go for a puffer jacket with down or synthetic fill.
  • Remember insulated pants. You will lose considerable heat through your legs, although you may not notice because they are not very sensitive to the cold.
  • Use a hard hat liner or a balaclava to keep your head and face protected
• Layer 3: Outer Layer
  • This is your shield against the elements.
  • Look for a waterproof and breathable jacket with a hood that will keep you dry from rain and snow while allowing moisture from sweat to escape.
  • Valuable features include seam sealing or seam taping so there are no leaks if you work in the rain and armpit zippers that allow you to cool off without removing the jacket.
  • Winter days are short, so use high-visibility gear to be visible in the dark.

Should I use Mittens or Gloves? The Great Debate

Mittens are generally warmer than gloves because your fingers can share warmth. But gloves offer better dexterity.

• Consider a compromise: Split-finger or lobster gloves offer a good balance of warmth and flexibility.
• Key features: Look for a cozy inner layer, adequate insulation, and a waterproof outer layer.
• Valuable features include large cuffs that fit over your jacket sleeve, removable liners, glove leashes, and wrist cords that secure your gloves or mittens to your wrists so you won’t drop one in the snow.
• Chronically cold hands? Consider electrically heated gloves.

What are the Best Types of Socks for Extreme Cold?

• Two pairs are better than one: Wear a thin, moisture-wicking sock with a thicker, cushioned wool sock on top. This strategy has also been proven to reduce blisters.
• Boot fit is crucial. Make sure your boots are big enough to accommodate your thick socks. If they are too tight, your feet will quickly get cold.
• Chronically cold feet? Consider electrically heated socks.
• Insulate your feet: If you’re standing still for long periods, bring a piece of foam to stand on to keep your feet off the cold ground.
• Slips and falls cause devastating injuries every winter. Find the best slip-resistant boots for winter.
