Relationship between cold weather and heart disease explained

Do you experience dizziness after ascending stairs? Do you find yourself feeling weaker or running out of energy later than usual? If these symptoms manifest during the winter months of December, January, or February, it could be indicative of heart-related issues that tend to be more pronounced in colder weather.

Various studies caution about an elevated risk of heart problems during cold weather, emphasizing the need for vigilance as these issues can potentially progress into serious conditions.

A study from 2013, documented in the National Library of Medicine, highlights that the likelihood of developing atrial flutter or atrial fibrillation rises in colder temperatures, peaking during January and February. Atrial flutter involves rapid beating of the heart's upper chambers (atria), leading to an increased heart rate that is often regular, as explained by the Mayo Clinic.

Atrial flutter, classified as a type of arrhythmia resulting from disruptions in the heart's electrical system, may not pose an immediate threat. However, approximately half of those with atrial flutter could progress to full-blown atrial fibrillation over time. This escalation could potentially increase the risk of a stroke or heart attack, according to information from the Washington Post.

An analysis of 15 studies conducted in 2015, encompassing over 125,000 patients, revealed a seasonal pattern for atrial fibrillation, with higher occurrences during winter and a decline in the summer, reaching its lowest levels in July.
