抽煙對咽喉健康不利，容易引發(fā)咽炎。當(dāng)我們吸煙時，煙霧中的有害物質(zhì)會直接進(jìn)入咽喉，刺激黏膜，導(dǎo)致咽喉發(fā)炎。

煙草中含有許多有害物質(zhì)，其中最主要的是尼古丁和焦油。尼古丁是一種強(qiáng)烈的刺激物，會使咽喉黏膜變得干燥和敏感，容易受到感染。焦油則是一種黏稠的物質(zhì)，會沉積在咽喉的黏膜上，阻塞氣道，增加細(xì)菌滋生的機(jī)會。

抽煙還會降低咽喉的免疫力。煙霧中的有害物質(zhì)會干擾免疫系統(tǒng)的正常功能，使咽喉對病原體的抵抗力下降。這就意味著，吸煙者更容易感染細(xì)菌和病毒，引發(fā)咽炎。

咽炎的癥狀包括喉嚨痛、干燥、灼熱感、咳嗽和咳痰等。如果咽炎持續(xù)不治療，還可能引發(fā)其他并發(fā)癥，如咽部潰瘍、聲帶炎等。
