Why Do We Get Fevers?

The human body is a wonderful creation which is capable of doing wonders which haven’t still been figured out completely. But any beautiful creation has to face setbacks and its greatness can only be measured by the extent to which it can overcome problems. The human body is formulated in such a way that it fights off any ill causes which disturb its normal functioning. But while doing so, the body does give us information that there is something wrong with it and that is when we seek medical help. For instance, if you don’t feel all that great and on placing your hand on your forehead, you feel warm and sweaty which makes you tired overall, you’re most likely dealing with a fever.

A fever is confirmed when the temperature of the body rises way beyond its normal fluctuation range. While the rectal temperature may not be accurate, fever is more accurately confirmed by taking the oral or armpit temperature as they approximately give an idea of the overall body and can be easily measured. Viruses and Bacteria look for hosts which suitable conditions to thrive and the human body takes steps to prevent that from happening. If it isn’t a viral or bacterial fever, the likely cause could be Amphetamine abuse or alcohol withdrawal and heatstroke or environmental causes.


Body temperature is regulated by the Hypothalamus in the brain which can be compared to a thermostat in real life. In events of infiltration of germs in the body, the normal behaviour gets disrupted. Once the hypothalamus detects these changes, the temperature of the body is increased and this takes away the comfortable range of living for the germs in the blood stream. A fever acts as an indicator to let you know that the infection needs treatment. Another common thing associated with fever is shivering, which is how the body starts to generate more heat to elevate the temperature, making us feel warmer.

Although the heat increase in the body is used to drive the germs away, it should be taken care of that it doesn’t exceed beyond a certain limit. If it exceeds 105 degrees Fahrenheit, proteins and body fats get exposure to temperature stresses. If the fever goes for a longer duration and high temperature, necrosis, fevers, delirium, infarctions and seizures aren’t uncommon to follow. There are extremely rare cases when the hypothalamus doesn’t function properly due to fevers and instead of the body temperature becoming really hot, it drops to a low temperature.

There’s a saying that is heard whenever a fever is observed that, “Feed a cold, starve a Fever.” Quite simply put, food should be taken in extremely less quantities in case of a fever. This is true and has three reasons to back it up. Eating more would stress the digestive system under fever, the body could interpret the food as allergens and excessive fever would lead to seizures, collapse and delirium which are accentuated by eating.
