现代医学研究认为,脚是人体的“第二心脏”。冬季,寒邪极易通过脚部侵袭人体,使旧病复发、病情加重或恶化。尤其老年人由于脏器老化,功能衰退,对寒冷刺激的适应性和耐受力更差。因此,老年人要安全过冬,必须特别重视脚部的保健。保持合适温度人的双脚远离心脏,供血相对减少,同时脚的皮下脂肪层又薄,保温性能差,所以冬季脚部最容易受凉。研究表明,当人的双脚表面温度维持在28～30℃时,感觉最为舒适。因此,老年人应采取综合性措施,比如穿厚
Modern medical research that the foot is the body’s “second heart.” In winter, the cold can easily invade the human body through the foot, make the old disease relapse, aggravate or aggravate. In particular, the elderly due to aging organs, functional decline, the more cold stimulation of the adaptability and tolerance worse. Therefore, the elderly to be safe winter, must pay special attention to foot health. Maintain the right temperature of human feet away from the heart, the relative reduction of blood supply, while the foot of the subcutaneous fat layer and thin, poor insulation, so the most vulnerable to winter cold feet.

Therefore, the elderly should take comprehensive measures, such as wearing thick
