Increasing Allergies

October 05, 2018
The Rise of Allergy and Asthma Symptoms
Asthma and allergy rates have been rising over the past few decades and there are several theories as to why that might be the case. Climate change can trigger a higher pollen and mold count because of rising temperatures. Certain fungus' produce more spores when there is more CO2 in the atmosphere. Airway exposure to spores can induce allergy symptoms. Even receding water from hurricanes like Florence can contribute because they leave behind bacteria, chemicals, viruses, and mold. 
Another catalyst could be the lifestyle in the modern world. People are increasingly living in cleaner environments and have less exposure to bacteria that would train their immune system not to attack ragweed or dust too harshly. Antibiotic use has also been blamed. According to Accuweather, "Researchers suggest that early antibiotic use changes the bacterial flora, which impacts the development of allergic diseases such as asthma. Other studies suggest that increased use of acetaminophen (Tylenol) in children might have an impact on the increased risk of asthma and allergies."
Another common theme is that most people are also getting less sunlight today thus lessening their bodies' production of vitamin D that is essential for lung and immune system development. 
The overall weakening of immune systems can also be caused by increased levels of stress felt by individuals in an increasingly complicated world. A compromised immune system will contribute to the body being less capable of fighting off allergic diseases.
