After very hot weather around 45C, places like Delhi-NCR suddenly experienced rain and even hailstorms. Even though the rain felt nice and gave relief, the fast change from hot to cool and humid weather can make the body weak and lower immunity, so people can fall sick more easily.
Quick weather changes can also disturb the air by lifting dust, pollen, and pollution that had settled during dry days. When the air becomes more humid, germs like viruses and bacteria grow faster. This can increase the chances of breathing problems, skin infections, and stomach illnesses in people.
Why do colds and coughs spread rapidly
A sudden fall in temperature can temporarily weaken the immune response, making the body more vulnerable to viral infections. As a result, many people experience symptoms like sore throat, runny nose, mild fever, and body aches soon after such abrupt weather changes.
Allergies and breathing issues rise
Rainfall after long dry spells disturbs settled dust, pollen, and pollutants in the air. This can trigger allergic reactions such as sneezing, itchy eyes, and congestion. It may also worsen asthma and bronchitis, especially in people already sensitive to sudden environmental changes during monsoon transition periods.
Why do digestive problems increase
High humidity and poor hygiene conditions during rains increase bacterial growth in food and water. Eating contaminated or improperly stored street food can lead to stomach infections, food poisoning, diarrhoea, and nausea. Such illnesses are common during the monsoon season when food spoils quickly in damp environments.
Skin infections and mosquito risks
Damp weather, sweat, and wearing wet clothes for long periods create an ideal environment for fungi and bacteria to grow. This can cause skin problems like rashes, itching, athlete’s foot, and other fungal infections, especially in skin folds.

After rains, water often collects in open areas, coolers, and clogged drains. This stagnant water becomes a perfect breeding place for mosquitoes, increasing the risk of diseases such as dengue, malaria, and chikungunya in the days following heavy rainfall.
Who is most at risk during sudden weather changes
Children and elderly people are more sensitive to sudden weather changes because their immune systems are usually weaker. People who have asthma or other breathing problems may also face flare-ups when temperature, humidity, or air quality changes quickly. Those with low immunity or long-term illnesses are more likely to get infections during such weather shifts.

What are the best ways to stay safe during sudden weather changes
During sudden weather changes, it is important to take care of your health by following some simple habits. Drink enough water even if the weather feels cooler, because your body still needs fluids after hot conditions. Try to avoid getting wet in the rain, and if you do, change into dry clothes as soon as possible to prevent illness. Eat fresh, home-cooked food and avoid street food to reduce the risk of stomach infections. Maintain good hygiene by washing your hands regularly and keeping yourself clean to stay away from germs. Protect yourself from mosquito bites by using nets or repellents and by not allowing water to collect around your home. Also, carry an umbrella or a light jacket so you are prepared for sudden rain and temperature changes.
