The winters are finally here, and we can’t wait to whip out our woollies. But the sudden drop in the temperature has left many of us sniffling, sneezing and coughing. In a matter of a few days, the weather has moved from humid and warm to dry and cold. Such a big shift in temperature will obviously have an effect on our health. So don't be surprised if you are ambushed by a variety of sicknesses. Dr Vasant Nagvekar Infectious Disease Specialist, Global Hospitals, Mumbai and Dr Ambanna Gowda Consultant physician, Fortis Hospital Bangalore say that flu is not the only health problem that the winters bring. A sudden dip in the temperature can affect everything from your skin to your cardiovascular health.
“Low temperature can cause veins and arteries to narrow down. Blood becomes more viscous, which increases the load on the heart. This can lead to cardiovascular stress,” says Dr Nagvekar.
“When the blood vessels get constricted, it can increase incidences of heart attacks,” adds Dr Gowda. Christmas Eve Heart Attacks! December 24, 10 PM is The Riskiest Time For Heart Attacks, Says Study.
When the air turns cooler, the blood vessels in the nose and the upper airways narrow down. This constriction affects the defence mechanism of the respiratory system, which wards off viruses and bacteria in the air. This leaves us vulnerable to the germs that cause common cold and flu.
“Breathing cold air causes cooling of the upper respiratory tract, which dries out the mucosal membrane. In sensitive people, the drying may cause damages to the epithelial cells,” says Dr Nagvekar.
Constriction of the blood vessels in the upper airways can affect the movements of the cilia, hair-like structures in the lungs that clear out mucus and dirt in the respiratory tract. Cold stress can also stimulate substances that cause inflammation in the body, increasing chances of bronchospasm, or narrowing of the bronchi.

“As the temperature drops in winter, health problems start to rise. People tend to spend more time indoors in close contact with each other in homes, stores, malls and restaurants. This means flu, coughs and colds are spread more easily,” adds Dr Gowda.
The skin is the largest organ of your body, and protecting it goes beyond just cosmetic reasons. “Sudden dip in temperature shocks your skin and strips it moisture of”, says Dr Gowda. A cooler temperature also means more hot baths, which can add to the skin’s dryness.
