3. Understanding Fever

A fever is a temporary increase in your body temperature, often due to an illness. It is a natural response of the immune system to fight off infections.

3.1. What is a Fever?

A fever occurs when your body temperature rises above its normal range. The average normal body temperature is around 98.6°F (37°C), but this can vary slightly from person to person. A fever is generally considered to be a temperature of 100.4°F (38°C) or higher.

3.2. How Fever Relates to Food Poisoning

In the context of food poisoning, a fever is a sign that your immune system is actively combating the pathogens causing the illness. When harmful bacteria or viruses enter your body through contaminated food, your immune system releases chemicals that raise your body temperature. This elevated temperature can help inhibit the growth and spread of the pathogens.

3.3. Types of Fever

Fevers can be classified based on their severity and duration:

Low-Grade Fever: A temperature between 100.4°F (38°C) and 102.2°F (39°C).
Moderate Fever: A temperature between 102.2°F (39°C) and 104°F (40°C).
High Fever: A temperature above 104°F (40°C).

3.4. Managing Fever at Home

For mild to moderate fevers associated with food poisoning, you can take several steps to manage the symptoms at home:

Stay Hydrated: Drink plenty of clear fluids like water, electrolyte solutions, and herbal teas.
