1. Fever: The Body's First Line of Defense

Fever is one of the most common and recognizable symptoms of the flu, often acting as the body's first line of defense against viral invaders. When the immune system detects the presence of the influenza virus, it triggers a response that raises the body's temperature, creating an environment less hospitable to the virus. This increase in temperature can help slow the replication of the virus, giving the immune system a better chance to combat the infection. However, a high fever can also be debilitating, leading to discomfort and fatigue. It's important to monitor fever levels, especially in children and the elderly, as extremely high temperatures can lead to complications. Managing fever with over-the-counter medications and ensuring adequate hydration can help alleviate symptoms while the body fights off the infection.
