Why Do You Get A Fever? | Earth Lab


Hey there Head Squeezers I hope you’re well
and if you’re not this question is for you. It comes in from drooney187 who asks on YouTube
Why do you feel hot when you catch a cold? Yep, its that time of the year isn’t where
we all seem to have a cause of the sniffles and by that I really mean you’re probably
suffering from man flu you’re completely full of snot you feel like you’ve got barbed wire
in your throat and your temperature is utterly sky-high. Give me an ironic thumbs up if so
far this winter you’ve been struck down. So what’s going on? Well your body heats up
naturally; it’s a natural response to fight the virus. You catch a cold if your body temperature
drops and also if you inhale droplets of water that contain rhinoviruses and adenoviruses.
Those viruses are always about but in winter when your body temperature has dropped because
of the cold weather and maybe you haven’t been wearing enough layers. My coat is over
there. Your body just can’t fight off that viral infection as well, in warmer temperatures
your body gives off an anti-viral immune signal when can defend against that sort of viral
infection. But when it’s cold it can’t do that as strongly so the viruses set off a
little Christmas party in your body. And that’s why you get sick.
Now over the centuries those viruses have evolved to work very very well at your natural
body temperature of 37 degrees C. It’s the proteins that replicate themselves that work
best at that temperature. Very crafty. So what your body does, it increases your internal
temperature by one or two degrees so it will take a day or two on the sofa or watching
a box set or chilling out in bed, but your body will manage to fight off those viruses
and then it’s party over. So unfortunately those hot sweats may be keeping
you up all night but it is your body fighting back against the virus. You just have to grin
and bear it. That’s all the time I’ve got right now, please do keep sending in your
questions, stay away from those sneezers and happy Head Squeezing.

  1. You guys who think this video is completely wrong and the main reason people catch a cold is due to closer proximity with contagious people during winter time… are so full of hot air. Or certainly never been in Pacific island countries where the temperature is a constant hot and humid all year round.

    In Indonesia for example, where temp hovers around 30°c, population density never change that much for the majority of the population day to day throughout the year. But sure enough, when someone gets too cold for an extended period of time (playing in the rain and doesn't get dried up immediately when you come home into a cool house with AC set at 16°celc), you will get catch something. Guaranteed.

  2. When it gets colder, the virus gets in your body through your nose because, in cold temperatures, the blood vessels in your nose constrict and blood moves from your extremities (including your nose) to your more vital organs as a defense mechanism. With less blood irrigation in your nose, not enough white blood cells are present to defend that entrance from those viruses which are always present.

  3. W/r/t the thumbs up… If I haven't been ill this winter, do I have to thumb down? I don't want to throw off any survey you're attempting.

  4. Why do I feel cold when I have a fever.
    Keeps switching between hot and cold.
    Body fighting bacteria doesnt quite cover it. (at all)

  5. Is that really true about getting a cold because the body is cold, I though it was because we are indoors more in winter and therefore around more people.  (As others have stated here!)

    I enjoy your programmes but this one on fever is totally unscientifically wrong. A hundred years ago people believed your idea and the treatment of fever was to cover febrile patients to ensure over heating in the belief that the body was being helped to combat the infection.

    We now know that viruses and bacteria 'prefer' a higher temperature and THEY readjust the body temperature to a higher one (by exerting control over the hypothalamus where temperature is regulated) to allow them to reproduce faster.

    Now the treatment of fever has changed. Febrile patients are covered in damp sheets under a fan in order to reduce the temperature to the disadvantage of the microbes.

  7. How does the Universe have an affect on Earth, is the earth weightless? or is it just falling slowly and slowly and going to hit a ground down there?

  8. A wild Sniffle has appeard!
    Robin was sent out!
    The wild Sniffle used sniffle!
    It's super effective!
    Robin was sniffled!
    The wild Sniffle ran away!
    Robin was hurt by sniffle!
    Robin blacked out! (But woke up in bed later, fighting the Sniffle!
     

  9. The definition of fever by Dr. Chang C.H.'s Origin Point Medicine — your body is losing internal heating energy rapidly.
    The remedies for the fever symptom are simple. 1) Put a warm pad on the back of head in order to supplying heating energy by external way.
    2) Drink heavy dosage of warm ginger soup regularly.
    3) If the patient feels uncomfortable then depressing his/her acupuncture points where are situated behind two ears' lowest points respectively.
    That's all.

  10. reason why im watching this: i want to know what is this weird spiky feeling in my tongue when i have a fever that making me crazy.
    heres the whole story, i hope someone can answer it.
    every time i get a fever, 5 or 2 minutes  before my fever cured…. i have this spiky feeling in my tongue its making me crazy and sweaty what ever i saw something (clothes,blanket ethc.) i scratch my tongue on it( lost self control in 3 minutes) then after that my fever are gone because the feeling my tongue making me sweat
    so what is this thing called? is it normal?

  11. I have an ando virus or something! I am pretty sick! I haven't been to school in 3 days! Whenever I walk I feel super tall! But thanks!!

  12. amazing information, that why we should not use any medication to decrease the fever, the body temperature will never reach more than 42 C' what you need to do when you or your child have fever is to keep drinking liquids and be hydrate. If you are not hydrate properly you may experience a seizes. That why if you have a child you need to make him/her drink a lot of liquid ( no artificial drinking ) best liquid will be natural juices, coconut water and filter water.

  13. I think the reason you get sick during the winter more is NOT because of our body temperature dropping, but rather because people tend to congregate inside more passing communicable diseases.

  14. The Christmas Party is sooo cute!
    In America we use Christmas lights all throughout the year for night lights and fun!
    On the cieling blue ones mimmick constellations and are quite soothing.
    Have a blessed day!
