Why do you get a fever when you're sick? - Christian Moro

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.
