What are sinuses?

Sinuses are hollow air filled cavities found in the forehead (frontal), behind the cheeks (maxillary), between the eye (ethmoid) and deep behind the eyes (sphenoid). The sinuses are lined with cells that produce mucus while others are part of the body’s immunity system.

Sinus Functions

  • When you breathe in, the sinuses humidify and warm the air
  • They also filter the air
  • Insulate adjacent organs such as the eyes and nerves
  • Increases voice resonance
  • In case you are hit on the face, the sinuses act as a buffer against trauma
  • The sinuses also make the skull lighter

Sinus infection causes

  • As mentioned earlier, many a sinus infection start-off with a cold which result from a virus.
  • If you are allergic to pet dander, dust, dust mites, cold, smoke, fungi, perfumes, other chemicals etc., the allergies inflame nasal passages and may lead to sinus infections
  • Whereas Bacteria may not cause as sinus infection, it causes other complications that compound the infection.
  • You may also find that the cause may be nasal polyps that have grown in your nasal passage or sinuses resulting in nasal passage blockage.
  • As much as you love to swim or dive, note that spending a lot of time in chlorinated pool may trigger attacks. Sinuses may also be irritated when water is pushed in while diving
  • Reduced air pressure during take-off and landing when flying may present challenges to you if are prone to sinus infections
  • Are you suffering from a disease that has weakened your immune system? Then, fungi may cause the infection.
  • Could you have overused nasal decongestants? Remember, the sprays is to be used for four days or less.

  • Dry air may thicken mucus and cause or worsen the infection. Get a humidifier to moisten the air and assist to loosen the mucus. Click here to get to know how a humidifier helps you prevent and mange a sinus infection.
  • Could you possibly have a congenital nasal deformity such as narrow passages, cleft palate, deviated nasal septum (wall between the nose)? You could also have tumors that may be blocking the nasal passages.
  • Do you suffer from other chronic conditions such as asthma, gastroesophageal reflux disease (GERD) or a dental infection?
  • Could you be undergoing treatment for a head injury or where you have tube inserted in your nose?

The common cold vs sinus infection (sinusitis) relationship

Most sinus infections start as common colds. When you have a cold, you will experience a viral infection affecting the upper respiratory tract (URT) and nasal passages resulting in a runny nose and/or cough.

However, the sinus infection will be accompanied by other symptoms discussed here-below which persist even after the URT infection symptoms have cleared.

The cold infection takes about a week to heal whereas a sinus infection takes longer to clear.

Are sinus infections (sinusitis) contagious?

As already mentioned, the sinus infection most often starts off as a cold. When you have a cold, you may of course spread the virus but not the sinus infection.

The virus will be spread through the air or by passing it from hand to mouth, nose or eyes. It is thus important to wash your hands with soap and water and avoid close contact with those with colds or flu.

If you are the one with the cold/flu, cover the mouth and nose as well and properly dispose the discharge.

If the sinus infection is as a result of a bacteria complication, you cannot spread it.

Sinus infection (sinusitis) classification

According to American Academy of Otolaryngology (source), a sinuses infection can be;

Acute—lasts for less than four weeks and more often than not part of a cold.

Chronic—lasts more than 12 weeks and caused by prolonged inflammation rather than an infection that lasts for long. The sinus infection that keeps recurring is also chronic.
