Why Flu Increases in Winter in Pakistan – Causes, Symptoms & Prevention

Flu Increases in Winter 

Every year, as winter begins in Pakistan, cases of flu and seasonal viral infections rise sharply. From Karachi to Gilgit, hospitals and clinics see an increase in patients suffering from cough, fever, sore throat, and body aches. But why does flu increase in winter in Pakistan? Let’s understand the real reasons, symptoms, and how to protect yourself and your family.

What Is Flu?

Flu, also known as influenza, is a contagious viral infection that affects the respiratory system, including the nose, throat, and lungs. It spreads easily from person to person through coughing, sneezing, or close contact.

Why Flu Increases in Winter in Pakistan

1. Cold Weather Weakens Immunity

During winter, low temperatures reduce our body’s immune response. In Pakistan, many people are exposed to cold air without proper winter clothing, especially early mornings and late nights, making them more vulnerable to flu viruses.

2. Dry Air Helps Viruses Survive

Winter air in Pakistan becomes dry, especially in Punjab, KPK, and northern areas. Dry air allows flu viruses to survive longer in the environment and makes our nasal passages dry, reducing their ability to block germs.

3. More Time Spent Indoors

In winter, people stay indoors more often, keeping windows and doors closed. This lack of ventilation allows viruses to spread quickly in homes, offices, schools, and public transport.

4. Poor Sunlight & Vitamin D Deficiency

Shorter days and foggy weather reduce sunlight exposure. Vitamin D, which is essential for immunity, becomes deficient in many Pakistanis during winter, increasing the risk of flu and infections.

5. Air Pollution & Smog

Cities like Lahore, Faisalabad, and Karachi experience severe smog and air pollution in winter. Polluted air irritates the lungs and weakens respiratory defenses, making flu infections more severe and common.

6. Weak Hygiene Practices

In many areas of Pakistan, people do not follow proper hygiene such as frequent hand washing or covering their mouth while sneezing. This increases flu transmission, especially in crowded places.
