During summertime, the mucus becomes thick and sticky because the air is very dry in hot days. This makes ciliary evacuation of mucus very difficult, resulting in the blockage of the sinuses, accumulation of bacteria and in turn generating congestion.

Sinusitis is an inflammation of 1 or more paranasal sinuses and it could be originated by viruses or bacteria but also air pollutants or allergies (very usual at this time of the year due to pollen, weeds and grasses). More than 50% of the sinusitis cases are triggered by Streptococcus pneumoniae and Hemophilus influenza and in a lower percentage Moraxella catharrhalis. (1, 2, 3)

When sinuses are blocked, common symptoms includes mucus build up, pressure, stuffy nose and headaches. (4)

The most effective way to prevent sinusitis in summer is controlling allergies and avoiding infections. Prevent respiratory infections in the upper tract by washing your hands more often and drinking liquids abundantly to keep your mucous membranes moist and free of bacteria.
