Complications Bacterial sinusitis is nearly always harmless (although uncomfortable and sometimes even very painful). If an episode becomes severe, antibiotics generally eliminate further problems. In rare cases, however, sinusitis can be very serious. Osteomyelitis. Adolescent males with acute frontal sinusitis are at particular risk for severe problems. One important complication is infection of the bones (osteomyelitis) of the forehead and other facial bones. In such cases, the patient usually experiences headache, fever, and a soft swelling over the bone known as Pott's puffy tumor. Infection of the Eye Socket. Infection of the eye socket, or orbital infection, which causes swelling and subsequent drooping of the eyelid, is a rare but serious complication of ethmoid sinusitis.

"Regular" dehydration from air conditioning and/or fans is unlikely unless you're already bordering on dehydration.
Did you know that nearly 90% of what people think are sinus headaches are actually Migraines? These are some of the symptoms that make people think they have a sinus headache:
runny nose or nasal congestion
red or puffy eyes
facial pain or pressure
All of those can be Migraine symptoms. A Migraine can inflame the trigeminal nerve. The trigeminal nerve has branches in the face, One runs above they eyes, one runs along the sinuses, and the third runs along the lower jaw. As a result, the pain may be felt near the sinuses, which are air pockets between bone in the lower forehead, cheeks and behind the nose. You can see a diagram of this in Pathways of Migraine . Sinus headaches rarely occur unless you have a sinus infection
