Winter, pollution pose double threat to asthmatic & heart patients

With the onset of winter and a sharp dip in the night temperatures, health experts have cautioned that asthmatic and cardiac patients are more vulnerable to illness if they fail to take adequate precautions. Doctors have already begun witnessing a rise in the number of patients reporting breathing difficulties and chest discomfort at city hospitals.

Civil Surgeon Dr Swaranjit Dhawan said the cold weather, coupled with increased air pollution, poses serious health risks. “During the winter season, pollutant-mixed air settles down in the lower layers of the atmosphere, the same zone where we breathe. This causes heaviness in the chest and makes breathing difficult for patients with respiratory problems,” he explained.

According to Senior Medical Officer at Civil hospital Dr Rajnish Kumar, winter months are also particularly harsh for asthmatic patients. “In cold weather, the immune system becomes weak and the airways become hypersensitive. Asthmatic patients often experience more frequent and severe attacks. They must not ignore even mild symptoms and should consult a physician immediately if they feel any breathing discomfort,” he said.

Health experts further warned that fog and frost, expected in the coming weeks, could worsen respiratory conditions. “A number of viruses become active in the winter season, leading to an increase in infections. People suffering from chronic diseases like asthma or heart ailments need to be extra careful,” said Dr Kumar.

Doctors also noted that the winter season affects heart patients significantly. “Low temperatures cause blood vessels to constrict, reducing blood flow to the heart and vital organs. This can lead to an increase in blood pressure and put additional strain on the heart,” said a cardiologist from a local hospital. “The risk of heart attacks is higher in winter as the heart has to work harder to pump blood through narrowed arteries,” the doctor added.

The experts also highlighted that children are highly susceptible to cold-related ailments such as cough, cold and flu. They advised parents to ensure that children are properly clothed, especially during early mornings and late evenings, to protect them from the cold air.

Doctors have urged residents to take simple preventive measures; keep warm, avoid exposure to cold winds, wear masks to prevent respiratory infections, and maintain a balanced diet. “Precaution and timely medical advice can prevent complications during the cold months,” said Dr Dhawan.
