The normal temperature of the human body is 98.6 degrees Fahrenheit or 37 degrees Celsius. When the body temperature rises above this, it is called fever. Fever is a natural response of the body, which is adopted by the immune system to fight infection. When bacteria, virus or any other infection enters the body, the immune system becomes active and raises the body temperature. This reduces the chances of growth of harmful microorganisms and helps the body fight infection.
Fever is not just a disease, but it can be a sign of an internal problem in the body. Sometimes it is mild and gets cured on its own in a few days, while in some cases it can also be a symptom of serious diseases. It is important to understand the exact cause of fever and control it so that the possibility of any serious disease can be prevented.

Major causes of fever

Fever can occur due to many reasons. Some of its major causes are as follows:

●    Infection is a major cause. Viruses can cause common cold, cough, flu, etc., while UTI, typhoid, TB, and throat infections are caused by bacteria.
●    Viral infections include diseases like dengue, chikungunya, and coronavirus, in which fever is the main symptom. Joint pain and skin rashes are also seen along with fever in dengue and chikungunya.
●    Fever can occur many times even after vaccination as the body's immune system reacts to any new medicine or vaccine. This is common in children and mild fever may occur within a few hours of vaccination.
●    Arthritis or other inflammatory diseases can also be the cause of fever. In some cases, fever is also seen due to diseases like autoimmune disorders. Body temperature can also increase due to living in a very hot environment or heatstroke.
●    Other causes include any type of inflammation in the body, hormonal imbalance, allergy or reaction to certain medicines.

Symptoms of fever

When there is fever, many types of symptoms can appear in the body, which mainly include:

●    Feeling excessive heat in the body
●    Feeling cold or shivering
●    Headache, fatigue and weakness
●    Muscle pain
●    Excessive sweating
●    Dry throat
●    Lack of appetite
●    Feeling irritable or lethargic.

The higher the fever, the more severe its symptoms can be. Small children and the elderly need to be more careful during fever, because their immune system is weak.

Method of measuring fever

The thermometer is used to measure fever. Nowadays digital thermometers are used more, with which the temperature can be measured easily. Earlier mercury thermometers were used, in which the mercury had to be shaken and brought down. The temperature is measured by placing the thermometer under the tongue or in the armpit.
Now infrared thermometers based on new technology are also available in the market, which can be detected about fever by applying them on the forehead. If the body temperature is more than 100.4 degrees Fahrenheit (38 degrees Celsius), it is considered a fever.

What to do in case of fever?

Some special precautions should be taken in case of fever, so that the body can get relief:

●    Take plenty of rest and avoid physical exertion.
●    Consume plenty of water, juice and soup so that the body remains hydrated.
●    Wear light and comfortable clothes so that the body gets cool.
●    Placing a cold water compress on the forehead can provide relief.

Consult a doctor in serious condition

In some cases, fever can be serious and medical consultation is required. If the fever exceeds 104 degrees Fahrenheit, persists for a long time and is not reducing with normal measures, or there is difficulty in breathing, chest pain, vomiting, confusion, or extreme weakness, then a doctor should be contacted.

Ayurvedic Solution: Patanjali's 'Fevogrit'

Natural herbs have been used in Ayurveda for centuries to control fever and infections. Patanjali has developed an Ayurvedic medicine called 'Fevogrit' using modern scientific methods.

Key Herbs Present in Fevogrit:

Fevogrit is a blend of various natural medicinal herbs, mainly:

●    Chirayta: Antipyretic and helpful in increasing immunity
●    Giloy: Immunity booster and rich in anti-pyretic properties
●    Karanja: Helpful in reducing inflammation and infection
●    Kutki: Helpful in maintaining the health of the liver and digestive system
●    Tulsi: Rich in anti-bacterial and anti-viral properties
●    Rose: Helpful in cooling the body

Scientific Research and Testing

The effectiveness of Fevogrit has been tested through scientific research. This Ayurvedic medicine was evaluated in the Bacterial Endotoxin (Lipopolysaccharide)-Induced Fever model of mice. In this test, Fivogrit reduced the elevated fever in mice. It controlled the protein levels and gene expression of inflammation-promoting markers such as TNF-α, IL-1β and IL-6.

Research published in international journal

This research on Fevogrit has been published in an international research journal called Animal Models and Experimental Medicine. This research confirms that Ayurvedic medicines can be effectively developed based on scientific research and modern testing methods.

Conclusion
Fever is an important response of the body's immune system, which helps prevent infection. However, high fever or prolonged fever can be a sign of serious problems. Fevogrit developed by Patanjali is a scientifically proven Ayurvedic medicine, which has proven to be helpful in controlling fever through natural herbs.
