10 Key Signals of Seasonal Flu You Shouldn’t Ignore
3. Fatigue: The Energy Drain of Influenza
Fatigue is another hallmark of the flu, often leaving individuals feeling drained and lethargic. This overwhelming tiredness is not merely the result of the body's fight against the virus but also a consequence of the immune system's heightened activity. The energy that would typically be used for daily activities is redirected towards combating the infection, leading to a significant decrease in stamina and endurance. Rest is vital during this time, as it allows the body to focus its resources on healing and recovery. Pushing through fatigue can prolong the illness and increase the risk of complications. Listening to your body's signals and prioritizing rest can accelerate the recovery process, helping you regain strength more quickly.
4. Cough: The Persistent Companion

A persistent cough is a common symptom of the flu, often lingering even after other symptoms have subsided. This cough is typically dry and hacking, resulting from irritation and inflammation in the respiratory tract caused by the virus. While coughing serves as a mechanism to clear the airways of mucus and debris, it can be uncomfortable and disruptive, especially at night. Over-the-counter cough suppressants and expectorants can provide relief, but it's important to use them judiciously, as they may not be suitable for everyone. Staying hydrated can help thin mucus, making it easier to expel, while a humidifier can add moisture to the air, soothing irritated airways. If a cough persists or is accompanied by other concerning symptoms, it's advisable to consult a healthcare professional for further evaluation.
