Cold triggers vasoconstriction, increasing blood pressure and heart rate, potentially causing heart attacks and clot formation, a key factor in heart attacks and strokes.
Strokes, neurological issues
Hypothermia poses a significant threat to the body, disrupting neurological functions, increasing stroke susceptibility, and causing shivering, which can increase heart stress.
Asthma, COPD
Cold air constricts airways, posing risks for pre-existing conditions like asthma or COPD, and increasing the likelihood of cardiovascular events due to the strain on the respiratory system.
Frostbite
Frostbite, caused by freezing temperatures, can compromise blood flow, increasing the risk of tissue damage and cardiovascular challenges linked to cold exposure.
Psychological stress
Extreme cold can trigger stress hormones, affecting the autonomic nervous system, potentially causing cardiac events or exacerbate existing conditions. Adequate protection, layering, and warmth are crucial preventive measures.
