What happens to our body when we get hypothermia ? And why exactly our body responds to coldness like that ?

Hypothermia is your body getting cold and its reaction. It tries to handle this through various stages. You start with shivering which is your body’s way of raising the temperature by use of your muscles. This often includes an increase in heart rate and blood pressure to carry more warmth from your core to your extremities. When that doesn’t work, your body starts trying to conserve warmth by slowing down bodily functions such as slower heart rate and pulse. This is to preserve the heat in your core. Your hands and feet will cool off quickly and you’ll start to feel lethargic and have a decrease in cognitive ability. Eventually, systems start shutting down leading to death.
