Studies show that hospitalisation and mortality rates of heart failure patients are higher during winter season. This is majorly because the rapid drop in temperature causes various physiological changes that leads to worsening of disease.
There is some evidence to suggest that winter can be associated with an increased risk of heart failure in certain individuals, although the exact relationship is complex and multifactorial.
Several factors during the winter season may contribute to this increased risk:
Cold weather can lead to vasoconstriction (narrowing of blood vessels) and increased blood pressure, placing additional strain on the heart. This can be especially problematic for individuals with existing heart conditions.
Winter is commonly associated with an increase in viral respiratory infections, such as the flu or common cold. These infections can put stress on the cardiovascular system and potentially exacerbate heart failure symptoms.
People tend to be less physically active during the winter months, which can lead to weight gain, decreased cardiovascular fitness, and a higher risk of heart-related problems.
Seasonal dietary habits may change during winter, often leading to the consumption of calorie-dense, high-sodium foods. This can contribute to fluid retention and increased strain on the heart.
Managing heart failure involves proper medical care, adherence to medications, lifestyle modifications, and regular monitoring of symptoms.
