Danger Dust

As these clouds of dust sweep across the region, medical professionals have weighed in on its effects.

Family physician Dr Sherry Belle said the dust in the atmosphere could adversely affect the ENT (ear, nose, and throat) organs as well as the eyes through several mechanisms.

“The size and composition of the particles, the duration of exposure and an individual’s sensitivity, such as pre-existing allergies or asthma, all play a role in how severe those effects may be. In the nasal cavity, dust particles irritate the mucosa and can lead to rhinitis.

Symptoms

“Patients often present with sneezing, nasal congestion, a runny nose and post-nasal drip. In those with allergic rhinitis, the dust can trigger a histamine response and exacerbate symptoms dramatically,” she said.

Belle further said that dust inhalation could also inflame the throat, noting that common symptoms included dryness, scratchiness, or even a sore throat.

“Many develop a reflex cough as the body tries to expel the particles and those with chronic pharyngitis or laryngitis may experience a notable worsening of their condition.

“Nasal inflammation from dust may impair Eustachian tube function. This can cause a sensation of ear fullness or mild hearing changes and, in some, even mild itching or discomfort in the outer ear canal, especially if there’s underlying dermatitis or eczema.”
