That is why you breathe heavily when you excercise, to keep the blood and oxygen flowing enough for your muscles.
Giant pandas insulate their body heat to keep them warm.
they keep us warm and are energy reserves
It helps keep warm.
Astronauts on the space station have a controlled climate with heating systems to regulate temperature. They also wear special clothing that helps to maintain their body heat. Additionally, the station has insulation to minimize heat loss.
