How does rain affect the presence of crested wheatgrass pollen in the air?

Rain significantly reduces the presence of crested wheatgrass pollen in the air. This is because the water droplets in the rain capture the pollen particles and bring them down to the ground, effectively clearing the air. Lowered concentrations of allergens reduce the likelihood of allergenic reactions among susceptible individuals.

However, this is only a temporary effect. Once the rain stops and the atmosphere begins to dry, the pollen can be re-introduced into the air. This often happens due to wind or human activities that stir up dried out pollen. This means after a rainstorm, there can potentially be a spike in pollen levels, leading to more severe allergic reactions.

Moreover, continuous rain over a few days may encourage lush growth of grass, which could result in greater pollen production once the grass begins to flower. Therefore, allergic reactions may intensify several days after prolonged rainfall.

To manage such situations, allergy sufferers are advised to stay indoors as much as possible during high pollen times, usually on dry, windy days. When going outside, it is recommended to wear sunglasses to protect the eyes and to change clothes or shower to remove pollen upon coming back indoors.

For symptomatic management, antihistamines, decongestants, and nasal sprays could be used. In particular cases, immunotherapy, such as allergy shots, may be recommended by a healthcare provider. These medications reduce the severity of symptoms by helping the body's immune system resist allergy triggers.

Monitoring local weather and pollen forecasts can also aid in allergy management. On days with high pollen count forecasts, especially a few days after rain, allergy medication can be taken preemptively to reduce symptoms.

Remember, each person's reaction to pollen can vary greatly; some people might experience severe symptoms, while others may not react significantly. Anyone experiencing severe allergies should seek immediate medical attention.
