Sahara Dust in Central Texas
- Posted on: Jul 28 2026
What is Saharan dust?
Saharan dust, which refers to a mass of fine particles, sand, and dry air from the Saharan desert in Northern Africa being carried westward by trade winds, usually reaches the southern United States around summer. This usually arrives in Central Texas and Austin around June and lasts through August.
How can Saharan dust affect the ears, nose, and throat?
Particles from Saharan dust can be quite small, often under 10 microns in diameter. Due to their size, they can easily be inhaled and enter the upper and lower respiratory systems. These affect anyone, though it is likely to cause more severe problems in people with pre-existing conditions like asthma, allergies or chronic sinus disease. Anyone with a compromised immune system is also more likely to be at risk.
Nose: These dust and sand particles can occasionally function as true allergens, meaning they can cause histamine release in the nose, which leads to nasal congestion, facial pressure and postnasal drip, similar to pollen and dander allergies. However, they can also cause irritation to the lining of the nose, resulting in similar symptoms. In patients with nasal swelling, sinus drainage can potentially be impaired, resulting in a sinus infection. Inhalation of dust particles can also cause
Ears: Some patients can experience ear pressure, fullness, or even hearing loss due to nasal swelling and irritation. This is because the eustachian tubes, which are responsible for equalizing ear pressure, open up behind the nasal cavity. The tissue swelling and irritation caused by dust inhalation can cause these tubes to be less able to perform their function, resulting in ear pressure and even fluid buildup behind the eardrums.
Throat: The lining of the throat and larynx can be affected by dust particles, causing a sore throat or hoarseness.
How can these symptoms be improved?
Generally, limitation or avoidance of outdoor activities is recommended. Use of a HEPA filter indoors can also reduce dust concentrations. Nasal saline irrigations and gargling with saltwater can be helpful in clearing dust from the nasal cavity and throat passages.
