Cold air can be deadly

BOISE, Idaho - We get it. You don't like having to prepare for an Antarctic expedition just because the dog needs a walk, but venturing out unprepared can have some serious consequences.

The time it takes for a body to cool down in any given temperature varies from person to person, but once the body temperature drops a few degrees below normal, hypothermia sets in According to a report in Outside Magazine, at 95 degrees, the body enters mild hypothermia, which triggers violent shivering.

At 93, amnesia starts to sink in, and you can forget where you are and how you got there. At 91 degrees, apathy sets in and getting to a warm location just doesn't seem like a big priority anymore.

By the time your body temperatures reaches 86 degrees, your heart is only pumping about two-thirds as much blood as normal and this can trigger hallucinations. So if Fido needs a walk, suck it up, and put on your gear, and don't forget to layer up.

"Next to your skin you want to have a wicking layer, something that will deal with the moisture when you do perspire and also add some warmth. And then you want to have an insulating layer. Fleece is great. Down insulators are great," says Carrie Gochnour, owner of Greenwood's ski shop.

Don't forget the hats and gloves too, which can protect your ears and fingers. They may seem important to you, but when faced with bitter cold, your body sees these as expendable and steals heat from them to protect your internal organs.

This can lead to frostbite, a condition where your tissues freeze and die. James Sailhamer brought his family to Boise for the holidays from sunny and warm California, and he knows better than to mess with the cold.

"Aww man. Not being from here, I don't know if we're doing it right, but long underwear, like I said, layers," says Sailhamer.

With highs in the 20s across the Treasure Valley it's not so cold that you can't get outside for some recreation, but it is cold enough that those who venture out unprepared could be in for some trouble.
