How do urbanization and land use change impact Needle Grass pollen distribution?

Urbanization and land use changes can significantly impact the distribution of Needle Grass pollen. With urbanization, construction activities disturb the soil where Needle Grass grows, causing their pollen to easily spread through the air and consequently increasing exposure rates. Moreover, land use changes such as deforestation, agriculture, and land development might lead to the replacement of local plant species with Needle Grass—facilitating the spread of its pollen.

Such situations can aggravate allergy symptoms for people sensitive to Needle Grass pollens, causing allergic reactions such as sneezing, runny or stuffy nose, itchy or watery eyes, itchy throat, and coughing. However, there are allergy pills available to manage these symptoms, such as antihistamines, decongestants, and nasal steroids that reduce inflammation and mucus production.

Nonetheless, it's important to bear in mind that care should be taken when using allergy medications, as they might have side effects. For instance, antihistamines can cause drowsiness or sleepiness, while decongestants may lead to insomnia, nervousness or increased heart rate. It's always recommended to consult with a healthcare provider about any severe or persistent allergies and before starting any new medication.

Also, strategies such as improving local land use plans, promoting more green spaces in urban areas, and spreading awareness about needle grass allergies can help mitigate the allergic impacts of urbanization and land use changes on public health.
