Cold is manageable when you know the rules
Millions of people live comfortably in sub-zero winters. Nearly all winter accidents happen because of simple mistakes with clothing, shoes, cars, or plumbing during the first few cold days.
If you grew up in a warm climate, nobody taught you the unwritten rules of snow and freezing weather. This page covers the basics that people from cold places take for granted.
If you only do three things
- Dress in three loose layers (never wear cotton next to your skin—it traps sweat and makes you freeze).
- Assume any dark, wet-looking pavement below 32°F (0°C) is invisible black ice.
- Never pour hot water on a frozen car windshield—the glass will shatter instantly.
What snow, sleet, freezing rain, and black ice actually are
Not all winter weather is the same. A foot of dry, fluffy powder is often much safer and easier to walk or drive in than a quarter-inch of freezing rain.
Dry powder snow falls when the air is well below freezing (usually under 25°F or -4°C). It is light, squeaks under your boots, and brushes off your coat easily.
Wet, heavy snow ('packing snow') falls near 30–33°F (-1 to 1°C). It packs into snowballs, sticks to power lines, and is very heavy to shovel.
Sleet is tiny, translucent ice pellets that bounce when they hit your jacket or windshield. Sleet is crunchy underfoot and less slippery than glaze ice.
Freezing rain falls as liquid rain that freezes the instant it touches cold pavement, cars, and trees. It coats everything in a smooth, glassy sheet of ice and is the most dangerous winter hazard.
Black ice is not actually black. It is a thin, completely transparent layer of ice over dark asphalt. It looks exactly like a harmless wet puddle until your foot or tire touches it.

Five mistakes almost every first-timer makes
- Wearing cotton hoodies, jeans, or cotton socks: Cotton soaks up sweat and melted snow and holds cold water against your skin. Wear synthetic, fleece, or wool instead.
- Wearing smooth-soled sneakers: Rubber sneaker soles harden like plastic in freezing cold and have zero grip on ice. Wear boots with deep lugs or slip-on ice cleats.
- Walking with your hands in your pockets: If your foot slips on ice while your hands are trapped in your pockets, you cannot catch yourself and your head hits the pavement.
- Pouring hot water on a frozen car windshield: The sudden temperature shock cracks the glass immediately. Use your car's defroster and a plastic ice scraper.
- Turning the heat completely off when leaving home for the weekend: If indoor temperatures drop, water pipes inside your walls freeze and burst, flooding the house. Keep your thermostat at 55°F (13°C) or higher.
Why does snow make your eyes hurt?
Fresh snow reflects up to 80% of UV sunlight—nearly four times more than water or sand. On a sunny day after a snowfall, wear UV sunglasses outside to prevent 'snow blindness' (a painful sunburn on your corneas).
