<\/p>\n

Frequent changes in temperature – such as sudden shifts between warm afternoons and cool evenings – can place unexpected stress on the immune system. Many people notice that they fall sick more often when the weather keeps changing – one day hot, the next day cool, then suddenly humid or rainy. These fluctuations affect the body\u2019s defence system, making infections more common. From coughs and colds to sinus infections, viral fevers, asthma attacks and lung infections, unstable weather has a direct influence on respiratory health.<\/p>\n

<\/p>\n

<\/p>\n

This doesn\u2019t mean the weather itself makes you sick. But it does create the right conditions for viruses, bacteria and allergens to affect you more easily.<\/p>\n

<\/p>\n

<\/p>\n

Understanding how weather impacts your immunity can help you prevent seasonal illnesses and protect your lungs throughout the year.<\/p>\n

Why Weather Changes Affect Your Immunity<\/strong><\/h3>\n

<\/p>\n

<\/p>\n

<\/p>\n

<\/p>\n

1. Dry Air Irritates Your Nose and Throat<\/strong><\/h4>\n

<\/p>\n

<\/p>\n

Sudden drops in temperature or humidity dry out the lining of your nose and throat.
This protective lining normally traps germs. When it becomes dry, germs can enter your system more easily, increasing your chances of catching a cold or throat infection.<\/p>\n

<\/p>\n

<\/p>\n

2. Viruses Survive Longer in Cooler Conditions<\/strong><\/h4>\n

<\/p>\n

<\/p>\n

When temperatures fluctuate, especially between warm afternoons and cool evenings, respiratory viruses tend to survive longer in the air and on surfaces. This is why seasonal flu, common colds and viral infections rise whenever the weather is unstable.<\/p>\n

<\/p>\n

<\/p>\n

3. Your Body Takes Time to Adjust<\/strong><\/h4>\n

<\/p>\n

<\/p>\n

A sudden temperature shift – for example, moving from a warm outdoor environment to a cold office, or vice versa – forces the body to work harder to maintain balance. This temporary stress can lower your defence mechanism, making you more prone to infections.<\/p>\n

<\/p>\n

<\/p>\n

4. Allergens and Pollutants Increase During Weather Shifts<\/strong><\/h4>\n

<\/p>\n

<\/p>\n

Dust, pollen and pollution levels often rise during seasonal changes.
For people with allergies, asthma or sinus issues, this can trigger:<\/p>\n
