allergies, Asthma, cold weather, pollen count

Last night, most of our region experienced our first “hard frost” (hard frost = temperatures below 28 degrees for a period of hours). This is GOOD NEWS for individuals with ragweed and other pollen allergies–why? Because Ragweed and many other pollen-producing plants cannot survive a “hard frost.” Today counts reveal no Ragweed or Grass pollen. Other Weeds are decreased to Low levels and Pine Tree pollen remains present at Very Low levels. Mold Spores (which are decreased with colder temperatures but hang around until there’s snow on the ground…) are decreased but remain Very High with Cladosporium Mold predominant.
