In addition to dense fog conditions, the Indian Meteorological Department has predicted minimum temperatures ranging from 7°C to 10°C across most parts of the plains of Northwest India. Furthermore, the Central Pollution Control Board has reported "very poor" air quality in the national capital, with an overall AQI of 381 on Wednesday. According to Dr. Praveen Gupta, the Principal Director of the Department of Neurology at Fortis Memorial Research Institute, there has been a 40% increase in brain stroke cases. This increase is directly correlated to the cold weather and pollution
Dr. Gupta explained that pollution leads to an increase in particulate matter, which in turn leads to the generation of oxidative reactive species. This eventually results in inflammation and endothelial dysfunction, leading to a significant increase in brain strokes. Prof. Vinay Goyal, the Chairman of Neurology at Medanta in Gurugram, added that the combination of cold weather and air pollution acts as a double-edged sword, causing a 20% increase in stroke cases
He emphasized the need to control modifiable risk factors such as hypertension, diabetes, and smoking, along with taking steps to reduce pollution and avoid polluted environments. The doctors also recommended using air purifiers indoors and wearing face masks when going out in polluted areas, particularly during morning walks. They advised against consuming excessive amounts of nuts during winters, as it can increase blood cholesterol levels. Additionally, they emphasized the importance of staying physically active but doing so during the warmer afternoons. Overall, the increased risk of strokes during winters is attributed to fluctuations in blood pressure, especially for individuals who do not control their hypertension during this time. When combined with high pollution levels, the risk of stroke multiplies
It is essential for individuals with cardiac or blood pressure issues to follow up with their doctors regularly.
