Seasonal factors

Your hay fever signs and symptoms may start or worsen at a particular time of year. Triggers include:

  • Tree pollen, which is common in early spring.

  • Grass pollen, which is common in late spring and summer.

  • Ragweed pollen, which is common in fall.

  • Dust mites, cockroaches and dander from pets can be bothersome year-round (perennial). Symptoms caused by dander might worsen in winter, when houses are closed up.

  • Spores from indoor and outdoor fungi and molds are considered both seasonal and perennial.
