Answers To The Interesting Health Questions
Today you can call me Professor Eloise (only kidding!) What I have for you today are questions you may have had in the past that you would like to know the facts about… I have searched for reliable sources for these fun facts. And as we enter the winter season I included interesting questions that revolve around the winter wonderland… And here they are:
Why does our nose run when we’re in cold temperatures?
answer from NPR
An interview done by NPR with the one and only, Dr. Andrew Lane. He’s the director of the Johns Hopkins Sinus Center.
Why is it that we’re all bundled up for the cold weather, except for our pretty faces because we’re talking to others, enjoying the social scene… when your nose feels cold, you lift your hand to your nose for a quick touch of the tip, and WHY? well because it’s no secret, your nose is running, drip, drip, drip… ‘dang, I hope others aren’t seeing this’, you think to yourself (no worries though, they’re busy wiping their noses too!) Why does this happen Dr Lane? … are you ready for the answer I found?…
The interview answers:
Well, it’s really a combination of two things. It’s part respiratory biology and part of it is physics, or thermodynamics. One of the main functions of the nose is to warm and humidify the air that we breathe so that when it reaches your lungs, it’s nice and conditioned. And in order to do this, the nose has to add some moisture to it.

And in order to do this, the nose has to add some moisture to it.
What’s happening is that the warm air that you’re breathing is condensing in the cold air, so you see it as little droplets of water. And that’s because cold air can’t hold as much moisture as warm air. When you breathe that air back out, it comes to the very tip of your nose where the nose is cold and that fluid is going to re-condense onto the surface of the nose and that will also run out.
Why and how do we get chills?
answer from wikipedia
A cold chill (also known as chills, the chills or simply thrills) is described by David Huron[clarification needed] as, “a pleasant tingling feeling, associated with the flexing of hair follicles resulting in goose bumps (technically called piloerection), accompanied by a cold sensation, and sometimes producing a shudder or shiver.” Dimpled skin is often visible due to cold chills especially on the back of the neck or upper spine. Unlike shivering, however, it is not caused by temperature, menopause, or anxiety but rather is an emotionally triggered response when one is deeply affected by things such as music, speech, or recollection. It is similar to autonomous sensory meridian response; both sensations consist of a pleasant tingling feeling that affects the skin on the back of the neck and spine.
I don’t know about you, but I’m not a big fan of the chills (cold chills being my least favorite!) But when you think about it, our bodies automatically respond to feelings and our surroundings and that ,my friend, is amazing! Our bodies are complex with everything they do and most of which is automatic.
The Facts Of Frostbite
Answer by Wikipedia
What causes frostbite? what happens to the skin? let’s find out the facts:
At or below 0 °C (32 °F), blood vessels close to the skin start to constrict, and blood is shunted away from the extremities via the action of glomus bodies. The same response may also be a result of exposure to high winds. This constriction helps to preserve core body temperature. In extreme cold, or when the body is exposed to cold for long periods, this protective strategy can reduce blood flow in some areas of the body to dangerously low levels. This lack of blood leads to the eventual freezing and death of skin tissue in the affected areas. Of the four degrees of frostbite, each has varying degrees of pain (1 being mild to 4 being the most severe frostbite).
When you have frostbite the decision to thaw is based on proximity to a stable, warm environment. If rewarmed tissue ends up refreezing, more damage to tissue will be done. Excessive movement of frostbitten tissue can cause ice crystals that have formed in the tissue to do further damage. Splinting or wrapping frostbitten extremities are, therefore, recommended to prevent such movement (use blankets, as many as you can!) Do NOT rub, massage, shake, or otherwise applying physical force to frostbitten tissues in an attempt to rewarm them it can be harmful.
Frostbite can happen so quickly in frigid temperatures, make sure you dress warm(even when you’re just jumping in a warm car!- you never know if your car might breakdown!)
There you have it, a few questions answered to make you a little more wise. Who doesn’t like to learn new things? (Especially when it comes to our bodies!)
