Stay hydrated to beat fall allergies

With fall allergy season just around the corner, stay proactive and get prepared to keep those symptoms at bay. One of the best ways you can reduce the severity of allergy symptoms like runny noses, itchy eyes and scratchy throats is by staying hydrated. 

What is the most common fall allergen?

Almost everyone tends to be vigilant in the spring when the air is full of pollen, but fall is actually a big season for allergies, too. One of the biggest fall allergens is called ragweed, a North American member of the daisy family found mostly in the midwest and on the east coast. Ragweed pollen is most abundant in the fall and can cause allergy symptoms like sneezing, runny nose, nasal congestion, headaches, irritated eyes, itchy throat and more. Ragweed releases pollen from August to November, but peaks in late September. 

What is histamine?

Histamine is released by cells in the immune response to injury and in allergic and inflammatory reactions and causes itching and swelling, symptoms typical to allergic reactions. Depending on whether the exposure was to the lungs, like via airborne allergens, or internal, like via food, histamines can produce different reactions like coughing and sneezing or diarrhea and vomiting. Common allergy medications like Benadryl, Allegra and Claritin are all antihistamines, designed to block those uncomfortable allergic reactions. According to Dr. Neeta Ogden, an allergy specialist and spokesperson for the American College of Allergy, Asthma and Immunology, dehydrated bodies produce higher levels of histamines and worse symptoms.

How does staying hydrated affect overall health?

Drinking enough water and staying well hydrated is important when it comes to regulating body temperature, keeping joints lubricated, preventing infections, delivering nutrients to cells, and keeping organs functioning properly. According to Harvard, proper hydration also improves sleep quality, brain function and overall mood.

1Coway air purifiers have been proven to trap dust, pollen, dander, viruses and bacteria in the air based on KCL (Korea Conformity Laboratories) testing.They have been tested in a 30㎥ size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2022 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum airflow speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

4The concentration of ammonia, acetaldehyde and acetic acid were proven to be removed within 30 minutes by FCG Research Institute, Inc. Human Life Science Lab. It is not a demonstration result in the actual use space. Not all odors and gases may be supported. → Tested with Coway Airmega 150, 160, AP-1512HH, AP-1512HHS, 400, 400S

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
