When the weather shifts, so do the challenges to your health. You may notice how a sudden dip in temperature, an unexpected shower, or even a change from humid to dry air seems to bring on sniffles, fevers, or sore throats. Among the most common concerns during such transitions is the flu. Unlike a cold, the flu can leave you weak, feverish, and struggling for days.
The good news? You can protect yourself. Flu prevention is not about doing one big thing; rather, it is about combining small, consistent actions with an understanding of how your body’s immunity works. Just as seasons change, your approach to health should adapt, too. Recognising early signs, strengthening your body from within, and knowing when to seek medical advice can make a world of difference.
The Department of Internal Medicine at the Manipal Clinics Begur, Bengaluru, is well equipped with top specialists, infrastructure and advanced treatment facilities, which help in early diagnosis and recovery from flu-related diseases.
Synopsis
Why Flu Becomes More Common with Changing Temperatures
The flu virus thrives in conditions where the body is a little more vulnerable. When temperatures shift suddenly, your immune system may not adjust as quickly. For instance, one day might feel warm and the next unexpectedly cool. This puts extra strain on your body as it works to maintain balance, and during this adjustment period, the risk of influenza increases.
Closed environments, like classrooms or offices with limited ventilation during colder months, also make it easier for the flu virus to spread. Add in lifestyle factors such as irregular sleep or reduced water intake, and you’ll see why the seasonal flu finds it easy to strike.
Understanding How Immunity Works Against Flu
Your body has a built-in defence system, immunity, that fights off infections, including the flu virus. But for immunity to do its job well, it needs support. Think of it as a shield that gets stronger when you nourish your body and weaker when you neglect it.
Immunity depends on many factors: balanced nutrition, quality sleep, hydration, stress levels, and physical activity. Even small lapses in these areas can make your body less efficient at resisting infections. That’s why flu prevention is never about a single solution; it’s about consistently giving your body the tools it needs to stay protected.
Strengthening Immunity for Flu Prevention
There are many ways to reduce your risk of influenza. Once you understand the importance of prevention, you can make simple lifestyle changes to stay healthy through fluctuating weather.
|
Balanced Nutrition |
Eating a diet rich in fruits, vegetables, whole grains, and proteins helps your immune system function at its best. Foods rich in vitamin C, zinc, and antioxidants are particularly useful in building resistance against infections. |
|
Regular Exercise |
Moderate activity like walking, cycling, or yoga improves circulation and helps your immune system respond faster to threats. |
|
Adequate Sleep |
Sleep is when your body repairs and regenerates. Lack of rest weakens immunity and makes you more vulnerable to the flu. |
|
Hydration |
Drinking enough water supports every function in your body, including the immune response. During weather changes, when humidity shifts, staying hydrated becomes even more important. |
|
Stress Management |
Chronic stress reduces your body’s ability to fight infections. Relaxation practices like meditation or deep breathing can help. |
Myths and Facts About Flu and Immunity
People have a lot of misconceptions regarding the flu, which can influence their prevention strategy. Let us debunk a few popular myths.
Myth 1: The flu is merely a bad cold.
Fact: The flu is contracted from a different virus and is much more serious than the average cold. It is accompanied by sudden high fever, body pains, exhaustion, and in extreme cases, severe complications.
Myth 2: Healthy individuals don't require flu protection.
Fact: Strong immunity is not a guarantee against contracting the flu. Prevention through vaccination and lifestyle minimises overall spread and shields the vulnerable.
Myth 3: Vitamin supplements alone will prevent flu.
Fact: Vitamins may aid immunity, but cannot substitute for vaccines or good habits. There must be a holistic effort.
What Happens If You Ignore Flu Prevention?
When you forgo flu prevention, you leave your body vulnerable to a rapidly spreading virus. The consequences can be anything from lost school or work time to more severe effects such as pneumonia, sinusitis, or exacerbation of underlying health conditions.
Children, pregnant women, and older adults are particularly susceptible to complications. That's why taking steps to increase immunity and practising flu prevention isn't merely about preventing disruption, it's about protecting long-term health.
Daily Habits That Facilitate Flu Prevention
Small, careful habits can be used to curtail the transmission of the flu and enhance your immunity against it:
-
Regular hand washing with soap and water, particularly after exposure to public areas
-
Steer clear of facial touching, especially the eyes, nose, and mouth
-
Keep living areas clean and well-ventilated
-
Stay away from close contact with the sick, and if you become ill, rest well enough and reduce contact with others
If these habits are complemented with vaccination and an emphasis on immunity, they form a powerful wall of protection against seasonal flu.
Conclusion
As seasons change, your body also changes the way it adapts to the environment. The flu is a preventable yet common ordeal during such periods. By prioritising flu protection and taking care of your immunity, you can prevent yourself from getting ill as well as safeguard not only yourself but those people around you as well.

FAQ's
Colds tend to accompany light symptoms such as a runny nose or sore throat, whereas the flu attacks all of a sudden with severe fever, body pains, chills, and tiredness. If you experience severe tiredness and a sense of feverishness, then it is the flu.
Yes, since the flu virus keeps changing often. Vaccination on an annual basis will keep you covered from the most prevalent strains of that year.
A healthy immune system can lower your chances of getting infected and enable your body to combat the flu more quickly if you get it. But immunity is not the sole key; together with vaccination and good habits, it works best.
If you have a runny nose only, light exercise can be acceptable. But in the case of fever, congestion in the chest, or body pains, rest and let your body recover.
Fruits, leafy vegetables, nuts, seeds, yoghurt, and antioxidant-rich foods are very good for immunity. Along with these, remaining hydrated and reducing processed food intake can work wonders.
