Why does getting too cold explanation the body to stop working properly?
Normally, your body functions best at a temperature of 98.6 Fahrenheit (37 Celsius). As the body heat approaches 95, hypothermia sets in and the body starts shutting down unnecessary functions. Initial signs are divergent vasoconstriction (Blood vessels contained by the extremities constricting to prevent heat loss.), release of hormones to generate fry and an increase in heartbeat and respiratory rate. The body also responds by shivering and increasing body metabolism, but next to a further decrease surrounded by body temperature. This adjectives in turn reek havoc on your body, causing it to feat improperly. I hope this is nifty and that I answered your question fully.
The body wishes to be able to generate bake. When the body gets cold it's a systemic shut down starting from the furthermost extremities and working it's road in. First it pulls blood from the hand and feet to hold on to the heart, lungs and brain warm - these are VITAL for vivacity! Then it just works it's bearing inward until it eventually gets to the core of the body. As you lose circulation to your fingers, hand, arms, etc the tissue begins to die. Your organs and tissues have need of oxygen to live and without it it starts to breakdown and the body only just can't live like that.
our body is run by a huge complex series of chemical reactions, some create grill (burning energy for motion), others require fry (digesting food).
just close to the chemical reaction 'fire' the substances involve to be within a unmistaken temperature for the reaction to occur. wood burns, but single when it gets hot. matching is true in our body, copious biochemical reactions contained by our body require a temperature of atleast 35 degree to function. without this heat, your body becomes incapable of doing its available job and simply shuts down.
