As temperatures drop, so does our immunity’s guard—ushering in the inevitable flu season. Influenza, commonly known as the flu, is a recurring winter guest that often overstays its welcome. It brings fever, sore throat, body chills, and congestion, making even the cosiest winter days feel far less inviting. This viral infection spreads with remarkable ease—tiny respiratory droplets from coughs, sneezes, or even casual conversations can carry it from one person to another. Once exposed, symptoms typically appear within 1–4 days, quietly setting the stage for days of discomfort. While most cases resolve with rest and care, the flu can pose serious risks, particularly for children, the elderly, and those with compromised immunity. The good news? Prevention is still the best strategy. Regular handwashing, maintaining hygiene, and boosting your natural immunity can help you stay ahead. Traditional wisdom, like sipping kadhas or warm drinks, paired with modern awareness, can make a big difference. In this blog, we’ll look closer at what makes the flu so contagious, how it affects the body, and, most importantly, how to protect yourself and your loved ones. So, grab a warm cup of chai, sit back, and let’s get started. What is Influenza (Flu)? Influenza, commonly known as the flu, is a viral infection that affects the respiratory system. It spreads primarily through tiny droplets released into the air when someone coughs, sneezes, or even talks. These droplets can linger in the air or settle on surfaces, making it easy for the virus to hitch a ride when you touch your face, nose, or eyes. When you catch the flu, you may experience: (symptoms of common cold) Fever (feeling hot, sweaty, and uncomfortable) Sore throat and persistent coughing Fatigue and muscle aches, making even simple tasks feel exhausting Congestion and sneezing The flu typically lasts about a week, but rest and hydration are your best friends. Annual flu vaccines are also commonly recommended to help reduce the risk of infection. What Happens When the Flu Virus Enters Your Body? The flu virus doesn’t just stop by—it takes over your system in a series of well-planned steps. Here’s what happens: Entry Point: The virus enters your body through your nose, mouth, or eyes. This often happens when you breathe in virus-laden air or touch contaminated surfaces, including your face. Cell Invasion: Once inside, the virus attaches to cells in your respiratory tract (nose, throat, and lungs). It tricks the cells into letting it in and begins replicating. Rapid Multiplication: The virus hijacks your cells, creating thousands of copies of itself. As the new viral particles break free, they damage and destroy the infected cells, then attack nearby cells. Immune Response: Your immune system jumps into action, sending white blood cells to fight the infection. This immune battle causes inflammation, leading to fever, sore throat, and body aches. Flu Symptoms - Fever: The body raises its temperature to make it harder for the virus to survive. - Sore Throat & Cough: Damaged respiratory cells trigger discomfort and coughing to expel the virus. - Fatigue & Body Aches: Fighting the virus requires energy, leaving you feeling weak and achy. Recovery Phase: Over time, your immune system gains the upper hand, clearing the virus from your body. Most symptoms subside within a week, though full recovery may take longer. Support your body with adequate rest, fluids, and symptom-relief measures to speed healing. Ayurvedic Perspective on the Flu In Ayurveda, the flu is categorised under Jwara (fever). It is primarily caused by an imbalance in the Kapha and Vata doshas, which are responsible for maintaining moisture, movement, and stability in the respiratory system. These doshas weaken immunity and affect lung health, increasing infection susceptibility when disrupted. How does the Flu affect the lungs? (According to Ayurveda) Mucus Accumulation: Excess Kapha causes mucus buildup, leading to congestion, heaviness, and difficulty breathing. Respiratory Inflammation: The body’s reaction to toxins (ama) causes inflammation, which aggravates symptoms and, if left unmanaged, leads to complications like bronchitis. Cough & Breathlessness: Imbalanced Vata contributes to dry or productive coughs, chills, and weakened lung function. Weakened Prana (Vital Energy): A respiratory imbalance can disrupt prana, or life force, resulting in fatigue, breathlessness, and reduced resistance to further infections. Why is there no vaccine for the Flu? (There is, but it changes every year) The flu virus is like a master of disguise—it constantly changes its “appearance” (surface proteins), making it challenging for our immune system to recognise and fight it. Scientists develop flu vaccines yearly based on predictions of the virus’s most likely strains. Sometimes, they’re spot on; other times, the virus mutates faster than expected. While researchers work toward a universal flu vaccine targeting all strains, regular updates remain our best defence.
