What haze does to your airways, and how to ease irritation

Hazy weather conditions can cause irritation in the nose, throat, and airways, leading to symptoms like sneezing, congestion, and breathing discomfort. The main concern during haze is the inhalation of fine particles that can exacerbate existing respiratory issues and dry out the nose. When these particles are inhaled, they travel deep into the respiratory system, causing irritation in the nose and lungs, and potentially leading to coughing, chest tightness, and airway inflammation.

Individuals with asthma, COPD, allergic rhinitis, or sinus problems are more susceptible to these effects. Children and older adults are also at higher risk due to their developing lungs or existing heart and lung conditions. To manage haze-related discomfort, using isotonic saline sprays or rinses can help wash away trapped particles and mucus, adding moisture to the nasal tissue.

Isotonic saline is gentle on the body's cells, making it suitable for regular use. To use a saline spray, gently blow your nose, stay upright, and insert the nozzle at the outer corner of the eye or ear, pointing slightly outward. Breathe in softly through your nose, and avoid sniffing forcefully. For a more thorough cleanse, a nasal rinse or bottle can be used with sterile or cooled water and the recommended saline mixture.

Bend over a sink, tilt your head sideways, and gently flush the solution through the nasal cavity, allowing it to exit through the lower nostril. Repeat on the other side. It's important to maintain good hygiene by cleaning equipment after each use and avoiding sharing. If symptoms persist or worsen, it's advisable to seek medical attention for a thorough check-up and potential treatment.
