秋分是二十四节气中的第十六个节气，意味着秋季过了一半，天气逐渐转凉。在这个季节交替的时期，人们需要注意调整生活方式以适应气候变化，尤其是饮食方面，因为正确的食物选择可以帮助我们保持身体健康，增强免疫力，预防感冒咳嗽等疾病。在中医理论中，秋天容易引起两种类型的咳嗽气喘——凉燥和温燥，了解这两种情况的区别有助于我们在秋分时节制定更有效的养生食谱。

什么是凉燥？

凉燥是由于秋季气候干燥，寒气渐盛所引起的咳嗽气喘症状。这种情况下，身体受到外界寒冷空气的影响，使得呼吸道黏膜失去水分而变得干涩，导致咳嗽气喘的症状。由于气候偏冷，所以称为“凉燥”。

什么是温燥？

温燥则是由于秋季天气仍然相对温暖，但同时空气中缺乏水分所致。在这种情况下，人体内的津液被蒸发，呼吸道也因缺水而感到不适，从而引发咳嗽气喘的现象。由于气温较高，所以称为“温燥”。
