Irritants
When your throat is exposed to several toxins or irritants, it may inflame the pharynx and other related organs. Some can be inhaled substances, such as industrial gases, cigarette smoke, and air pollution. Others are linked to foods and ingested irritants, such as chewing tobacco, spicy foods, or alcoholic drinks. Another possible irritant is dry air. The lack of humidity would make the throat become scratchy and dry. People living in areas with arid climates tend to deal with this trigger more often. Last but not least, the excessive use of air conditioners may also trigger throat irritation. [6]
