_Our bodies like to be nice and warm, usually around 37°C. This allows our internal functions to work at their best. But our bodies are constantly losing heat to the outside air.
When it’s cold outside, or if we jump into a cold swimming pool, or even if the air-conditioning is a bit strong, our body temperature can lower, sometimes to levels that are uncomfortable.
If our body temperature drops too low, our heart, nervous system and other organs are not able to work normally. If it falls to extremely low temperatures, called hypothermia, this can cause some organs to completely fail.
Our bodies have their own internal heaters to protect us against small changes in temperature. This is mostly thanks to the actions of our muscles, through a process called thermoregulation. It’s this process that leads our bodies to shiver when we’re chilly._
