Does our metabolism slow down when we are freezing cold?

Your metabolism slows down at first, but if you stay in the cold, it quickens to keep you warm and to keep you alive and not in hypothermia. Slowing your metabloism doesn't make you stay younger though, makes you fat... To stay younger your cells would have to freeze and you'd be just a young looking corpse afterwards!

As a person's core body temperature drops, their metabolic processes slow down. The problem is basically two-fold:
1) It is difficult to "restart" the bodily systems of a very cold person, as they tend to shut down.
2) Ice crystals form in the cells and blood at temperatures below about 0 degrees C. These cause massive tissue damage (try freezing and thawing a tomato or strawberry for instance).

Freezing food makes it last longer because at the temperatutres of a freezer (around -18c) all microbial life in and around the food is dormant, preventing it from metabolising with - and therefore spoiling - the food. If you were to sit in a freezer you'd simply reduce in temperature until you matched the temperature of the freezer. Which is 51c below the optimum temperature for the vast majority of all life on earth (for it is at +37c which the reactions between enzymes are at their most efficient.) So in short no, you die very soon as the organic processes inside you which keep you alive would not be able to happen.

No. I did some research on this matter. A chicken is supposed to last three months in a freezer - I put a chicken in my freezer but by the morning it was dead! I believe the same would be true for a human, Therefore if we keep cold we do not live longer.

It depends on how old they are when you get them. They only live 6-8 weeks to start with. If you get small crickets they will live longer. If you order large crickets they are older and won't last as long.

As temperature lowers our metabolism accelerates in order to keep normal temperature. As hypothermia sets in, our body begins to shiver, escalating to muscle spasms or involuntary contractions. The energy expenditure rises, as temperature lowers. That can be translated into a shorter life span.

yes your metabolism slows down, this is the basis for cryogenic freezing immediately after death. However, our bodies cannot survive such cold, so you would die before any major benefit could be obtained.

Of course it slows down when we are freezing, but try sitting in the freezer, you will soon kill yourself.

Our bodies have to work harder to stay warm, and we crave more food when its cold so i wouldnt think so. Being mammals we work more efficiently in warmer weather and are less stressed when its warm so i would say we wouldnt live longer.

my husband must think so - cos he keeps turning the heating down and telling us to put on a jersey and warmer trousers!!
