A person has a fever if their body temperature rises above the normal range of 98–100°F (36–37°C). Fever often occurs in response to infection, inflammation and trauma. As a person’s body temperature increases, they may feel cold until it levels off and stops rising. People describe this as “chills.”
Eating, exercise, sleeping, the time of day trusted source, and individual factors can also affect temperature.
When an infection occurs, the immune system will launch an attack to try to remove the cause. A high body temperature is a normal part of this reaction.
A fever will usually resolve on its own. However, if body temperature rises too high, it may be a symptom of a severe infection that needs medical treatment.
Fever occurs when an area in your brain called the hypothalamus (hi-poe-THAL-uh-muhs) — also known as your body’s “thermostat” — shifts the set point of your normal body temperature upward. When this happens, you may feel chilled and add layers of clothing or wrap up in a blanket, or you may shiver to generate more body heat, eventually resulting in an elevated body temperature.
Normal body temperature varies throughout the day — it’s lower in the morning and higher in the late afternoon and evening. Although most people consider 98.6 F (37 C) normal, your body temperature can vary by a degree or more — from about 97 F (36.1 C) to 99 F (37.2 C) — and still be considered normal.
Fever or elevated body temperature might be caused by:
- A virus
- A bacterial infection
- Heat exhaustion
- Certain inflammatory conditions such as rheumatoid arthritis — inflammation of the lining of your joints (synovium)
- A malignant tumor
- Some medications, such as antibiotics and drugs used to treat high blood pressure or seizures
When someone has a fever, they may also:
- shiver and feel cold when nobody else does
- have a low appetite
- show signs of dehydration
- have increased sensitivity to pain
- lack energy and feel sleepy
- have difficulty concentrating
If a baby has a fever, they may:
- feel hot to the touch
- have flushed cheeks
- be sweaty or clammy
With a high fever, there may also be irritability, confusion, delirium, and seizures.
If a person has a fever with a dry cough and tiredness they may have symptoms of COVID-19( most common symptoms)

Treatment for Fever
- Langhana(fasting): Aam being the main factor initiating Jwara by causing Agnimandya, Langhan becomes the first step in the treatment of Jwara. Also being a Rasapradoshaj Vyadhi, Langhan is indicated in Jwara. It helps to pacify the vitiated Dosha and stimulates the Jatharagni. However, Langhan should not be prescribed in case of Vataj, Shramaj, Jeerna, Kshataj, Kshayaj and Manas Jwara in which Dhatukshay has already set in. Shaman must be given in such cases.
