The Basics of Fever
Too many of us start losing our nerves when fever strikes. Well on the face of it, we might hit the panic button but technically and normally, fever is not dangerous. In fact, fevers are considered as the best possible signs of an underlying condition.
- Fever is simply referred as high body temperature than normal
- Fever can be caused due to several reasons such as infection, cold or flu, vaccination, and inflammatory disease
- Treatment is mostly home-based while over the counter pills are also used widely
What is a fever?
Fever is generally referred to as elevated body temperature which is higher than normal. Fever is not always a cause for concern; in fact, a short-term increase in body temperature actually heals the body or fight off illness. However, a severe increase in body temperature might require immediate medical attention, a condition known as hyperthermia.
Normal body temperature of a human being is around 98.6°F or 37°C. However, the temperature can go up and down depending on person to person and situation such as time of the day, intense exercise, menstrual cycle, exercise, etc.
- Fever occurs in infant if their body temperature exceeds 100.4°F or 38°C
- In children, the temperature should be within 99.5°F or 37.5°C
- Fever in adult occurs when their body temperature goes above 99 to 99.5°F or 37.2 to 37.5°C
What causes fever?
Fever is associated with physical discomfort and most people feel better when they take treatment. Our body temperature is controlled by a part of our brain known as the hypothalamus.
When infection or some illness attacks the body, the hypothalamus resets the body to a higher temperature.
The most common cause of fever is the infection such as common cold or flu, other may include:
- Infection of ear, skin, throat, lung, bladder or kidney
- Conditions that trigger inflammation such as arthritis
- Side effects of medicine
- Teething (in infants)
