Discover what happens in your body when you have a fever and why its
role in our immune response remains a mystery to scientists.
There are many mysteries around fever, but we do know that all mammals,
some birds and even a few invertebrate and plant species feel fever’s heat. It
has persisted for over 600 million years of evolution. But it has a significant
cost: for every degree increase in temperature, there’s a 12.5% increase in
energy required. So, why and how does your body produce a fever? Christian Moro
investigates.
