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.

i used to think as a child that it was to fry the bacteria away :<

[kushal-roy]

Body: Increases it's Temperature to combat pathogens.
Human: Takes medicine to lower the fever.
Body: *WTF*

[nabilh.]

I'm having a cold with fever now and that was useful to know

[feboalazan]

Ted Ed is actually the best teacher I have ever had in my whole life!

[jamiragr]

doctor: got syphilis? here's some malaria
patient:

[ziyaraeez]

Body: something is not right with me
Hypothalamus: time to heat you up

[arielvidriales]

As someone who has had syphilis, every time I hear the words "penicillin" or "Fleming" I feel immense gratitude and relief

*Virus interest body*
The body : I must initiate self-destruct

[vinayakgupta]

It is so damn amazing that our body does all that, without even us knowing

[michaelangelosaluta]

i keep trying to actually understand what it being said but the animations are so cute

[leah]

Anyone watching this with a fever?
: Thank you guys so much for 108 likes and your sweet opinions 😘

No matter how much I understand why I get fever, I can never avoid it.

[Andijt]

I guess that's why people say, "Starve a cold, feed a fever." I wonder if there's any real reason to eat less when you have a cold. ---> I looked it up and there's no reason to starve a cold. Good nutrition is important for the body to heal.

Watching this while lying down on bed and shivering! 🤒🥶🥺

[mushfiqurrahman]

Man, this really came in handy. I'm literally going through a fever right now.... brings some comfort to know that this whole fever thing is somehow good for me.🖤

Absolutely LOVE how the eyes on the lymphocytes correspond to the lobes in the cell types' nuclei. Neutrophils have 3 lobes, eosinophils have two lobes, etc...

The way I see this is that, our bodies for the most part, doesn't need external help when fighting its battles, but sometimes, due to our body's unparalleled dedication to fighting off a virus, it could actually kill itself (destructive temperature levels) and this is where doctors come in to override our bodies untiring natural defense.

[sreekersiva]

It gives me chills everytime I learn how they used to treat patients in the old times.

[luziaflone]

The animation is so simple yet so easy to understand
