Spring Pollen Exposure Triggers False Allergy Alarms
Spring allergy symptoms such as sneezing, nasal congestion, and watery eyes are often triggered by exposure to allergens rather than the season itself, portalredsalud.cl reported.
Immune System Responses to Seasonal Pollen
Seasonal allergic rhinitis occurs when the immune system mistakes normally harmless substances for threats. Upon exposure, the body releases histamine, a molecule that acts as both a hormone and a neurotransmitter, which drives symptoms like sneezing, nasal discharge, and congestion.
Dr. Rosa Meneau, an academic in Chemistry and Pharmacy at UCSC and Doctor in Sciences with a mention in Chemistry, explained that the body recognizes specific compounds as allergens and mounts defenses. This reaction typically spikes in spring due to high concentrations of pollen acting as a primary antigen.
Why Not Every Sneeze Indicates an Allergy
A common misconception is that any nasal congestion or sneezing during spring automatically signals an allergy. While these symptoms mimic other respiratory conditions, identifying the exact origin is essential before beginning any treatment.
Individual reactions to pollen vary widely. High environmental pollen counts do not mean everyone will experience symptoms, as sensitivity depends on specific individual allergens.
Risks of Unsupervised Antihistamine and Decongestant Use
Many people reuse leftover medications from previous seasons to manage spring discomfort. However, antihistamines do not cure allergies; they merely block the effects of histamine.
Dr. Meneau noted that patients frequently rely on indiscriminate medication use despite potential side effects. Depending on the active ingredient, antihistamines can cause drowsiness, dizziness, or dry mouth.
Decongestants carry distinct risks. While they temporarily reduce nasal swelling, certain products can raise blood pressure, trigger insomnia, or cause rebound congestion, a condition where symptoms worsen with prolonged use.
Arnoldo Miranda, Head of the Chemistry and Pharmacy Career at UCSC and Master in Pharmaceutical Sciences, warned that individuals sometimes take antiallergic drugs assuming they have an allergy, when they actually suffer from a different condition requiring specialized medical care. Simultaneous use of multiple medications can also lead to accidental duplication of active ingredients.
Frequently Asked Questions About Spring Respiratory Symptoms
Why does rebound congestion occur with nasal decongestants?
Prolonged use can produce congestion of rebote, meaning the congestion worsens when continuing to use them.
