Sinus headaches and fall. Why do people get them during the fall? From the friends and research that I’ve reviewed, it’s due to a number of factors.
First, weather changes. Like Spring, Fall is a time where weather fronts of low and high pressure change frequently and at extremes. This is commonly referred to as one of the causes of sinus pressure and headaches. But not only is it a cause, it is also a exacerbator that adds to the pre-existent condition and makes the pressure worse than it originally was. So even though it may not be the main problem or cause, it still contributes to it.
Secondly, the humidity can drop significantly in the fall. When this happens, mucous doesn’t flow as well and passages can become blocked. Also, allergens and bacteria in the nasal cavity do not clear out as well as usual. Regardless of the reason, it still leads to less drainage, more chance for infection, and many times, sinus pressure develops because of the clogged sinuses.
Thirdly, fall allergies (late grasses, and molds, and soil molds) may be triggered. With the congestion comes the possibility for clogged sinuses and less drainage; hence, the powerfully painful headaches.
