  When our body temperature raises above normal, that is, around 99°C or 100°C, we get fever. Fever is not a disease, but then how do we get it???

What is fever?

  Fever is a natural, protective response of our body to fight against germs and pathogens like bacteria, viruses, fungi, etc. These germs or pathogens cause diseases like flu, cold, etc. Hence, when these germs enter our body, our immune cells like white blood cells produce pyrogens. Pyrogens are secreted in our blood stream. 

Why do we get fever?

  A small part of our brain called as the hypothalamus, regulates our body temperature. When pyrogens reach hypothalamus, our body temperature starts to rise, thus causing fever.

  Moreover, many germs cannot survive in high temperatures. Thus, due to fever, they die and we remain safe.

Posts before October 2021 have been marked as "Old Posts". Less likely, but they might have out dated or incorrect information, ugly looking bits of code, no labels, etc. Don't get me wrong, many of these posts are top-notch and interesting too.

I thought it would be better not to delete or revamp these posts, even if they suck. The bitter truth is that old works always suck, but I take that as a positive tool to convey that I am growing. Besides there's no better way to showcase my journey without these old, messy, poorly written posts!
