HEALTH: How to deal with late summer allergies
Tree pollen is mostly responsible for the spring allergies, but in the summer, it is weeds and grasses that are the culprits.
These weeds include ragweed, cockleweed, pigweed, Russian thistle, sagebrush and tumbleweed. The grasses include bermuda, blue grasses, orchard, red top, sweet vernal and Timothy grass.
The most common offender, however, is ragweed, which starts to bloom in August, and its pollen can travel for hundreds of miles.
Summer heat and humidity with added air pollutants add to the burden of allergic disease. Dust mites love humid environment, and, therefore, those who have allergies to dust mites may feel worse as well.
