嗅觉的力量可能超乎你的想象

嗅觉，这个常被忽视的感官，其实蕴藏着巨大的力量。TED 会员兼化学感官研究员波勒 • 约瑟芬带我们一起探索其中奥秘。演讲中，她深入探讨了嗅觉背后的科学原理——从嗅觉如何唤起记忆与情感，到其在疾病早期检测中的潜力——并呼吁建立一个味觉与嗅觉的基线测试，打造更全面的医疗保健体系。

Smell is deeply tied to memory and emotion, yet most people would give it up before any other sense. Loss of smell can be an early warning sign of neurodegenerative diseases, sometimes appearing a decade before other symptoms. During COVID, millions experienced sustained smell loss, raising concerns about long-term impacts on brain health. Despite its importance, routine medical exams rarely test for smell, leaving critical clues to disease overlooked.
