While spring and fall tend to be the height of allergy season, summertime can also be an unpleasant time for those who suffer from seasonal allergies.
As you’re spending more time outside, your exposure to allergens like pollen and mold increases. In addition to the common environmental allergy triggers that exist during spring and fall, summer has its own set of unique factors that cause allergies to spike. High temperatures, carbon dioxide in the air, and air pollution all contribute to allergic reactions during summer months. Whether you’re headed to a music festival, the beach, or a rooftop barbecue, make sure to follow this guide on how to recognize and reduce summer allergy symptoms.
Air pollution causes problems all throughout the year, but it is especially prevalent and a factor in aggravating allergies during the summer. The warm temperatures and longer days are enticing to spend more time outside, however increasing your exposure to air pollution. Whether it’s the exhaust from motor vehicles, dust from construction, chemical sprays from groundskeepers, or cigarette smoke from a nearby tourist, air pollution irritates your respiratory system causing coughing and sneezing fits, itchy eyes, and even skin problems. Curious about how air pollution affects your skin? We wrote a whole blog post about it!
Several studies have shown that people who are allergic to dust mites saw their allergy symptoms worsen after a high ozone day, typically happening during warm summer days. In an interview with NBC, Dr. David Peden, director of the UNC Center for Environmental Medicine, Asthma and Lung Biology, encourages people to become familiar with what time of day ozone levels are the highest, to best prepare for your summer day.
In these studies, people with pollen allergies experienced an increase in sensitivity when exposed to the tiny particles in vehicle exhaust. Dr. Andre Nel, a professor in the department of immunology and allergy at the University of California at Los Angeles added to the NBC interview:
Interestingly, some of the worst air may be on or near freeways, and contrary to popular belief, the car’s air conditioner will not help. That will just pull in more air from the freeway, at this stage most cars are not manufactured with an efficient filtration system for these small particles.
Both doctors emphasize the importance of understanding how different types of pollution effect your existing allergies as the best way to prepare yourself for facing summer allergies.
Experts in the allergy, immunology and other related health professions have noticed an increase in patients suffering from allergies well past the typical spring allergy season. Dr. Kevin McGrath, a Board of Regents member of the ACAAI explained how research has shown a correlation between carbon dioxide levels and allergies:
We have all been seeing, clinically, increasing pollen seasons, a little longer pollen seasons…that’s our clinical experience, and most allergists have recognized that […] Here is the science: to show the reason why we’re seeing higher pollen counts and maybe a longer pollen season—and that would be the increase in carbon dioxide level.
Plants thrive on carbon dioxide, and with an increase of this in the air from the burning of fossil fuels and rising temperatures, plants and molds are producing more spores. The growth rate for molds and plants increases, and the growing season lengthens. Because of this extended growing season, allergy sufferers are experiencing allergic symptoms throughout the summer months. For a season that is celebrated for its outdoor activities, allergy sufferers are finding little to be excited about when faced with prolonged allergy symptoms.
High ozone and smog tend to occur on days when temperatures are very warm. This goes hand in hand with the first allergy trigger covered, air pollution. Heat in general has its own way of triggering allergic reactions, and that depends on the moisture levels in the air.
Hot and Humid: Warm temperatures mixed with very humid air quality create the ideal situation for mold to grow. And with increased carbon dioxide levels in the atmosphere, the more mold spores growing, the more problems there will be for allergy sufferers.
Hot and Dry: When air is dry, the protective layer of mucous lining your sinuses and nasal passages dries. When this happens it is much easier for bacteria or allergens to irritate your respiratory system, causing you to either get sick or experience allergic reactions. Heat also dries out the ground where pollen falls to, so when it is hot and dry out, pollen is more likely to be picked up by wind and travel through the air, worsening allergy symptoms. That’s why allergies tend to be bad on windy days during a dry spell.
While there is no cure to allergies, there are preventative measures you can take to protect yourself from having a full blown allergic reaction. While these environmental allergy triggers are virtually out of your control, what you can control is how well your prepare yourself to deal with these allergens. A lot of allergy prevention comes down to maintaining healthy indoor air quality and understanding how these allergens affect you.
Follow these preventative tips for facing summer allergies and keeping your indoor environment allergen free all summer long:
Much like any kind of chronic illness, dealing with allergies and asthma can feel like it is taking over your life. When it’s the height of summer and outdoor activities, that is the last thing you want to be dealing with. Knowing what preventative measures to take will prevent allergies from becoming a bummer on your summer plans.
