Cricketer Shardul Thaur - who had to be hospitalized because of a very high fever due to infection has now been discharged – but is unlikely to play the remainder of the Irani Cup matches. The Mumbai team star had played his match despite having a mild fever initially, as the day progressed and owing to hot and humid conditions in Lucknow, his health deteriorated – with a high fever of 102 degrees Celsius and he was taken into emergency shortly after the day's play concluded.

Doctors said Thakur required medical attention during the innings, taking breaks while his condition was regularly monitored.

According to experts, a fever, also known as pyrexia, typically occurs when your body’s immune system begins fighting an infection from a pathogen like bacteria or virus. It helps neutralize the pathogen by raising the body temperature to where it cannot survive.

However, if it continues to be high – there can be many other reasons like drug reactions, inflammatory diseases, autoimmune disorders, excess heat exposure, and other non-infectious conditions. These conditions cause fever by disrupting the part of the brain that functions as the body's thermostat.

Doctors say using an oral thermometer - 98.6 degrees Fahrenheit (F) is considered a normal body temperature, and anything above it needs to be taken care of.

Doctors say the symptoms of fever get worse as the temperature rises, and a few include:

• Feeling chills
• Severe headache
• Achy eyes
• Feeling constantly thirsty
• Loss of appetite
• Fatigue
• Nausea
• Dizziness
• Muscle and body aches
• Increased heart rate
• Pale skin
• Stomach upset

What are the dangers of a high fever?

According to experts, even though persistent high fever can cause brain damage and death – it is rare and more often associated with the underlying cause of the fever, like malignancy or cancer.

However, it is also important to know when a fever does not come down - it can be dangerous to your central nervous system. Temperatures higher than 102 degrees Celsius can lead to febrile seizures – also known as febrile convulsion or fever fit in children. In the long run, a high fever can cause permanent brain damage.

Doctors say treatment is unnecessary if you have a fever but are feeling fine, as it may come down on its own after it neutralizes the infection. Also, when it comes to children, if they have energy, there is no immediate danger. However, when fever-related symptoms begin to make you feel extremely fatigued and the temperature keeps going up, an over-the-counter fever reducer like paracetamol can provide short-term relief.

You can begin cold compress – with the help of ice and cold water – all over your body to bring down the temperature.

Rest and drinking lots of fluids can also help your body fight the underlying infection. Doctors also recommend a lukewarm bath.
