What Are Pollen Counts and Mold Counts?
A pollen count is nothing more than a measurement of how much pollen is in the air. It is expressed in terms of a concentration of pollen in the air in a specific area at a certain point in time. The exact measure is grains of pollen per cubic meter over a 24 hour period.
Pollen counts are collected using a special sampling device that is typically placed on a rooftop several stories above the ground. The device has a sticky surface that collects grains of pollen from the air. Since pollen is so easily spread over a wide area, a sampling taken in one area is usually considered valid for a large area, even an entire city.
Mold counts, like pollen counts, are a measurement of how many mold spores are in the air in a certain area at any given point in time.
Why Are Pollen Counts and Mold Counts Important to People With Asthma?
When you have allergic asthma, avoiding your triggers is the best action you can take to keep your asthma under control. When pollen and mold counts are high, you should stay indoors as much as you can. But you can't see pollen or mold with the naked eye. So the only way to know when the levels are high is to monitor official pollen counts or mold counts.
Even better than a current pollen count or mold count is a mold or pollen forecast. A forecast is a prediction of where the counts are headed, so it is more useful in planning your day or days ahead. Forecasts are based on current counts and weather conditions, as well as historical trends.
Where Can You Get Accurate Pollen Count & Mold Count Information?
You can get pollen counts from a number of different sources, both locally and online. During spring and summer, many local radio or TV stations may report pollen and mold levels. These may or may not be accurate, depending on where they are getting their information. The best and most current places to get pollen counts and mold counts may be online:
- Pollen.com, which specializes in pollen level monitoring, has up-to-the-minute reports for every area and will even email you your local counts on a daily basis.
- National Allergy Bureau, a division of the American Academy of Allergy Asthma & Immunology, has both pollen and mold counts by region.
- Weather.com, the website for The Weather Channel, offers both geographically-specific pollen counts and mold counts.
Keeping yourself informed about your local pollen / mold counts is one of the best ways to limit your exposure to them. You will probably not be able to avoid them totally. But hopefully, you will be able to control your asthma symptoms with attention to this detail.
