Why does our body get hot and cold?

In this episode we talk about how the skin feels coldness and hotness. We also talk about how the air outside is cold at night and warmer in the day and colder in winter and warmer in summer.

Our body is always losing heat. In winter we lose heat more quickly as the weather is colder. That is why we bundle ourselves up. We don’t actually get warmer because of the jacket we wear. We just lose our heat more slowly as the jacket insulates our body and keeps our body heat closer to our body. So you have to zip up your jacket to keep yourself warm.
