It’s all in the head: sinus facts

Did you know that if your sinuses weren’t hollow your head would be so heavy you wouldn’t be able to hold it up?

You also have more than one sinus. When hay fever strikes you might feel as though you have four hundred blocked sinuses causing your head to throb, your eyes to water and your nose to itch. Actually there are four pairs of air filled cavities known as sinuses. They’re hollow cavities within our skulls and facial bones and, because they’re weightless, it means or heads are lighter and can be held upright:-

  • the maxillary sinus is located behind the cheek, just above the molars (teeth). It is pyramid in shape and opens into the nasal cavity. These are the largest sinuses and are also the most likely location of sinus problems
  • the frontal sinus sits behind each eyebrow (often the source of that oh so familiar head throbbing, hay fever pain)
  • the ethmoid sinuses are located between the eyes behind the bridge of the nose. The ethmoid is a light, spongy bone.
  • the sphenoid sinuses (almost spherical) are located behind the ethmoid sinuses, behind the eyes.

The discomfort from “blocked sinuses” occurs when mucus, produced by our sinuses to flush away bacteria, gets trapped and this causes the feeling of pressure, facial pain and congestion so often associated with hay fever and sinus infection.

If you feel discomfort from sinus congestion, the cleansing action of a sinus irrigation kit like Flo Sinus Care may help relieve some of the pressure of excess mucus.
