民间常有‘喝酒吃辣可以祛寒御冷’的说法，尤其在寒冷季节或受凉后，不少人会喝点白酒、吃些辣椒来‘驱寒’。这种做法有一定道理，但需理性看待。从生理角度看，酒精和辣椒素确实能让人产生‘暖和’的错觉。酒精进入体内后会扩张皮肤血管，促进血液循环，使体表温度升高，从而带来短暂的温暖感；辣椒中的辣椒素则能刺激神经末梢，引发身体发热反应。然而，这种‘暖意’只是表面现象，并不能真正提升核心体温，反而可能因血管扩张导致热量更快散失，加重寒冷感。此外，过量饮酒不仅伤肝，还会抑制中枢神经系统，降低人体对寒冷的感知与应对能力；而过度吃辣可能刺激肠胃，尤其在空腹或体质虚弱时更易引发不适。因此，依靠喝酒吃辣来御寒并非科学方法。真正有效的防寒方式应是合理穿衣、保持室内温度、摄入高热量营养食物以及适度运动。若已受寒感冒，应及时就医，而非依赖辛辣酒食‘硬扛’。总之，适量享用辣味或小酌怡情无妨，但将其当作御寒手段则不可取。
There’s a common folk belief that ‘drinking alcohol and eating spicy food can dispel cold and keep you warm,’ especially during winter or after catching a chill. Many people turn to a shot of liquor or a plate of chili peppers to ‘drive out the cold.’ While there’s some physiological basis for this idea, it should be approached with caution.Alcohol and capsaicin (the compound that makes chili peppers hot) can indeed create a temporary sensation of warmth. Alcohol dilates blood vessels near the skin, increasing blood flow and making you feel warmer on the surface. Similarly, capsaicin stimulates nerve endings, triggering a heat-like response in the body. However, this feeling is misleading—it doesn’t raise your core body temperature. In fact, the vasodilation caused by alcohol may accelerate heat loss, potentially making you feel even colder afterward.Moreover, excessive alcohol consumption damages the liver and depresses the central nervous system, impairing your body’s ability to sense and respond to cold. Overindulging in spicy food, especially on an empty stomach or when unwell, can irritate the digestive tract and cause discomfort.Effective cold-weather strategies include dressing appropriately, maintaining indoor warmth, eating nutritious, calorie-rich foods, and engaging in moderate physical activity. If you’ve already caught a cold, seek proper medical care rather than relying on alcohol or spicy dishes as remedies. In short, enjoying spicy food or a small drink in moderation is fine—but don’t count on them as reliable methods for staying warm.
