Baby, it's cold outside...


Winter is well and truly here. The temperatures have plummeted, and everyone can see their breath when they breathe, even inside the house. So, what happens if you freeze to death?


The human body has a standard temperature of 37°C. Hypothermia occurs when the body temperature drops to 35°C or lower. People can easily experience hypothermia in the conditions we have outside at the moment and if it is raining it is going to make things a lot worse. The body loses heat about 25 times faster in water than in air.


Sub-zero temperatures can make the side effects a lot worse. If you are improperly dressed for the weather, hypothermia can set in in just under ten minutes. A drop in temperature prevents the organs from working properly. The heart pumps more slowly causing a reduced blood flow to important organs. This puts the body in a state of shock as oxygen supplies are limited. Other symptoms of hypothermia include amnesia and loss of consciousness. If the body temperature drops considerably to below 25°C, you would be at high risk of death.


However, in 2010 a man survived being submerged in ice-cold water for a period of time. His body temperature Was just 13.7°C, this is the lowest body temperature recorded and this man survived!! How, who knows?


The body tries its best to fight off the cold. The body insulates itself, with blood vessels moving away from the skin and extremities to keep the core warm. This is called vasoconstriction and it helps prevent heat loss. Shivering helps to raise your body temperature as it produces heat!

The fingers and toes are susceptible to frostbite in chilly weather because those areas will have reduced blood flow as the core tries to preserve heat.


So, wrap up this winter so this does not become your fate!
