As wintry cold weather continues, an urgent warning has been issued, stating that millions are at risk of a silent killer. Research has highlighted that extreme cold and warm weather can heighten the risk of death for individuals already grappling with underlying heart issues. Heart failure has been identified as a chief contributor to the excess deaths resulting from extreme hot and cold temperatures.
Cardiovascular diseases, often referred to as silent killers due to their asymptomatic nature in many cases, pose a severe threat to public health. The US-based researchers underscore that severe cold weather can adversely impact individuals living with illnesses such as ischaemic heart disease and heart failure, potentially elevating the risk of mortality for some.
In North India, low daytime temperatures have made winter unbearable for many, inflicting discomfort and draining energy levels. This extreme cold has also been linked to health complications, ranging from strokes to heart attacks. The body’s physiological response to freezing temperatures requires heightened effort. Blood vessels constrict in response to the cold, leading to increased blood pressure. Prolonged exposure to extreme cold can induce hypothermia, disrupting brain function and causing neurological issues. Moreover, respiratory symptoms in individuals with asthma, COPD, and similar lung disorders can be exacerbated by cold waves.
It is clear that extreme weather, whether cold or warm, can have substantial health implications, particularly for individuals with underlying heart issues. As the winter season persists, it is essential to take extra precautions and be mindful of potential health risks associated with the extreme temperatures.
