10 Key Signals of Seasonal Flu You Shouldn’t Ignore

5. Sore Throat: The Inflamed Passage

A sore throat is another common symptom associated with the flu, often resulting from the virus's impact on the respiratory system. The throat becomes inflamed and irritated as the immune system responds to the infection, leading to discomfort and pain, especially when swallowing. Gargling with warm salt water can provide temporary relief, as can throat lozenges and sprays designed to soothe irritation. Staying hydrated is also important, as it helps keep the throat moist and reduces irritation. While a sore throat can be bothersome, it typically resolves as the body's immune response clears the virus. However, if the sore throat is severe or accompanied by difficulty breathing, medical attention may be necessary to rule out other conditions.

6. Runny or Stuffy Nose: The Nasal Invasion

A runny or stuffy nose is a frequent companion of the flu, resulting from the virus's invasion of the nasal passages. The body's immune response to the virus causes the lining of the nose to swell and produce excess mucus, leading to congestion and a runny nose. While these symptoms can be irritating, they are part of the body's efforts to flush out the virus and other pathogens. Saline nasal sprays can help clear the nasal passages, while decongestants may provide temporary relief from congestion. It's important to use decongestants as directed, as overuse can lead to rebound congestion. Keeping the air humidified and staying hydrated can also help ease nasal symptoms, making breathing more comfortable.
