It's not even officially winter yet but temperatures across the country are plummeting. Forecasters say many people will be facing extremely frigid and dangerous conditions.
As an emergency room doctor there's one thing I see in nearly every patient who comes in with problems caused by bitter cold weather — they weren't properly prepared for it.
Here are some ways to protect you and your family:
Walk like a penguin
The number one winter injury in the ER is falling on the ice. Wrist fractures, shoulder injuries, back pain and head trauma —all from losing balance and hitting the hard ground.
When walking on snow and ice, keep an eye out for black ice and ice hidden under patches of snow and be ready for a fall.
The biggest tip: take your hands out of your pockets. Use your arms for balance. And if you do fall, as hard as it might be, try to relax and not land on one outstretched arm.
Walk like a penguin on ice: Walk slow, feet shoulder distance apart and take small waddle steps. That keeps your center of gravity over your front leg.

Wear good boots
Canadian researchers recently found that 90 percent of winter boots failed a walking on ice test. The boots that earned the highest marks for being slip-resistant have special outsole materials designed to provide better traction. You can check how your winter boots fared at Rate My Treads.
It's what happens before frostbite. It's the tingling feeling that hurts — your body's warning sign that you have to warm up that body part quickly.
When that cold part goes numb, you've got frostbite, and that's a medical emergency. Most people forget about the tips of the ears.
Pay attention to shivering
Shivering is a sign that your body temperature is dropping.
You're not in medical danger yet, but you're heading toward hypothermia, or dangerously low body temperature.
If you're still in the cold environment, these are four signs that you've crossed into moderate or severe hypothermia
- you're experiencing clumsiness or confusion
- you feel drowsy
- your shivering gets worse, or even stops altogether
In that case, get out of the cold immediately and seek a warm place. Get out of wet clothes. Bundle up in warm blankets.
The hat myth!
Wearing a hat is good; it keeps you warm. But you do NOT lose most of your body heat from your head.
The heat you lose from an uncovered head is not different from the heat you'd lose from an uncovered arm.
The myth started after an Army study from the 1950's found that soldiers who were bundled up except for their head, lost most of their body heat from their head.
Today, more than 60 years later, we know if they had been bundled up except for their legs, they would have lost most of their body heat through their legs.
That's why it's important to wear a hat and long pants when it's cold. Leave the shorts for spring, guys.
