Key points for individuals with pollen allergies to consider during spring are: Wearing a hat and sunglasses when going outdoors will help reduce pollen exposure. During periods of high pollen density, avoid spending long periods in outdoor areas, especially those with trees and grass, and refrain from intense physical activities outdoors. To prevent pollen from being carried indoors via hair and clothes, outdoor clothing should be changed immediately upon returning home, and a shower should be taken every evening.
