What Causes A Fever?


We have all called in sick at work or school,
at least a few times in our life. Whether we like it or not, we have all suffered
from fever. But, do you know what really causes fever
and what happens when we have a fever? Subscribe: Before we reveal the causes, do
not forget to click subscribe and ring the notification bell to stay updated with more
good quality content. Starting from being God’s way to deal with
sinners to being a genetic defect, we have heard all the myths related to the causes
of fever. In our childhood, many of us even believed
it to be true. However, as we grew older and became more
reasonable we learned that could not have been the truth. So, why do we get fever? It all starts with our brain, the organ that
makes our entire body work. There is a part of our brain known as the
hypothalamus, which controls our body temperature. In normal conditions, it maintains the body
temperature at 98.6 degrees Fahrenheit or 37 degrees Celsius. Find it hard to understand? Well, let us simplify it for you. Imagine your body is a machine, which operates
properly at a particular temperature. This means, it can neither too hot nor too
cold. There is a person sitting in the control room
of that machine and she/he is maintaining the temperature of that machine. That is exactly what the hypothalamus does
to your body. Your body is constantly working, even when
you are resting. Your heart is pumping blood, your blood is
circulating throughout your body and your lungs are inhaling and exhaling air constantly
— your body is very busy maintaining a particular temperature during all this work. But, at times the hypothalamus increases the
temperature of the body. This is what we know in general terms as fever. Yes, this is why you get a fever. But, why would the good ol’ hypothalamus
do this to us? Hypothalamus usually does this to protect
us from bacteria. Thus, saving us from a major disease. Here are some examples when it increases body
temperature. Cold Nothing invites more germs to the body than
a cold. When we have a cold, our immune system lowers
and makes our body vulnerable to diseases. A prolonged state of such a scenario may cause
major infections. Speaking of infections, it brings us to the
second point. Gastroenteritis This is one of the major infections of very
important organs in our body, the stomach and the intestines. Usually, this issue is caused by bacterial
toxins, but at times, the infection might be viral. If the infection is left alone then it may
lead to diarrhea. Other Infections Ever had an infection on your ear and that
led to fever. Yes, the hypothalamus does that to us and
not even infections of the ear, lung, skin, throat, bladder, and kidneys are left unchecked. In case of all these scenarios, a spike in
body temperature is normal as the hypothalamus is actually trying to neutralize the infection. Side Effects of Medication Remember the time you overdosed yourself with
pain killer because you thought that the pain was too unbearable. After that, you got diagnosed with fever. This is because your body did not require
the overdose of that prescribed drug and because of the overdose, your body may grow weak and
vulnerable to infection caused by bacteria or any form of virus. So yes, hypothalamus to the rescue one more
time. Blood Clots This one explains itself, blood clots usually
happen when you get injured to prevent spills. However, they can also form when they are
not needed and cause strokes or even heart strokes. Yes, you guessed it hypothalamus, our good
ol’ saviour helps us out one more time with its ingenious temperature control technique. Moving onto the next point… Autoimmune diseases and Hormone disorders Unlike the previous example, here is more
of a last-ditch, this is the best I could do effort from the hypothalamus. Our in-house or in this case, our in-body
protector cannot do much if we have an autoimmune disease such as lupus or inflammatory bowel
disease. Similarly, it cannot do much when you have
hormone disorders such as hyperthyroidism. So, it does the best it can do, but hey it
buys you enough time for the medicines to do their work. Just make sure you do not overdose yourself. Cancer This brings us to our last point. Sometimes the infection stays and leads to
cancer. You see, this is what the hypothalamus was
trying to avoid all this time. Even when you have cancer, it raises the temperature
to kill the infection. However, this is yet another unsuccessful
attempt from the hypothalamus as it cannot cure cancer on its own. Finding all this a bit too complicated to
understand? Here, let us simplify things for you… Imagine you are on your way to work in public
transport, you unknowingly contract a viral or bacterial infection. This infection has the ability to cause major
diseases. This is when your white blood cells form a
two-way defense, one group fights the infection with the body’s own good bacteria and the
other goes to the brain to inform it of the recent development. The information is received and our protagonist
hypothalamus goes to work. Bacteria and viruses need a suitable temperature
to survive, they cannot handle too much cold and too much heat. Guess who else knows it, you guessed it, the
hypothalamus. It increases the body temperature while the
immune system fights of the remnants of the infection. A victory against the invaders and the day
is saved thanks to our hero. The hero we need, but not the one we deserve,
the silent guardian, the watchful protector, our very own Dark Knight. See, it is not so tough after all. Fever often weakens the immune system and
make us vulnerable to different sorts of diseases. This is why we should not be completely dependant
on our hero. We need to do our part too. For home remedies, one of the best options
is always to sweat a lot and wipe the sweat with a towel. This regulates the body temperature, does
not allow the infection to settle down and helps the antibodies to do their work — fight
the infection. So yes, perspiration is good as long as you
do not let the sweat settle down. Drink lots of water to keep boosting your
body’s metabolism. However, in case you have a very high fever,
we would recommend you to go to a doctor, who knows a thing or two about how a human
body actually works. Depending upon the degree of fever, you will
be prescribed to mild or strong medicated drugs. Usually, antibiotics will be prescribed for
any form of bacterial infection or even strep throat. In case of very high fever, stronger medicines
are often prescribed. However, these medicines may have their own
side-effects. Hence, often a regulated dosage is prescribed. However, in the case of children and teenagers,
aspirin is avoided as it is linked to a condition called Reye’s syndrome. Similarly, in the case of other forms of fever-related
medication, it is often recommended that children and teenagers are given milder dosages. A lot of children might even have an allergic
reaction to antibiotics, in such a scenario, antibiotics should be avoided. So, remember to tell your doctor before she/he
prescribes medicine for your child. People with issues such as migraine, sinus,
or any form of breathing problems should be given milder doses of antibiotics to avoid
any form of side-effects. Well, there we go, that is all we had to talk
about the causes of fever. What did you think about the video? Did you find it helpful? Let us know in the comments section below,
we would love to hear from you.
