Mr. Lim, a 60-year-old man with high blood pressure and high cholesterol, maintained a daily running routine and engaged in weekly hikes to enhance his cardiovascular health. One day, amidst a sudden cold snap, he embarked on a mountain climb without wearing adequate clothing. Halfway through the hike, he suddenly felt as though a heavy stone was pressing on his chest—a heart attack had struck. Thankfully, he was saved by the prompt first aid administered by his companions.
Winter is the peak season for cardiovascular diseases. The low temperature and significant temperature fluctuations lead to vasoconstriction and increased blood pressure, elevating the risk of heart attack and stroke. A study in the United Kingdom found that for every 1.8 F (1 C) drop in temperature, there is a daily increase of 200 cases of myocardial infarction (heart attack). Older people and those with a history of coronary heart disease are particularly vulnerable to changes in weather.
