I undertand you're visibly troubled by this seasonal illness. However, this is easily explained by a condition called acute rhinosinusitis. Altered body immunity combined with pollen in the air from plants and roadside weeds can trigger the body to respond in a defensive way leading to swelling of the membranes of your nose, throat and sinuses. These swollen membranes then secrete mucous which gets accumulated within these sinuses leading to headache. Preventing this would be possible by covering your face with a balaclava mask or a scarf when riding your bike or going out in dusty places. If inspite of preventive measures this were to occur, steam inhalation helps in opening up sinuses leading to drainage of these accumulated secretions hence relieving the headache that causes you discomfort. Hope this answers your query. Feel free to contact me if there's any query.
