Main differences between hay fever and cold symptoms
Hay fever explained I Decomplicated
Hay fever is an allergic reaction to tiny particles you inhale from “allergens” such as pollen, causing the immune system to release histamine, leading to symptoms such as sneezing, a runny nose, and itchy eyes.
Colds are viral infections where viruses replicate in the nose and throat, triggering an immune response that also releases chemicals like histamine, resulting in symptoms similar to hay fever.
Key differences include hay fever causing itchiness and no fever, while colds can present with a fever, sore throat, muscle aches, and a cough with thick mucus.
Cold symptoms typically resolve within one to two weeks, whereas hay fever can persist for months during allergen exposure or recur seasonally.
Untreated hay fever can significantly impact quality of life and exacerbate asthma, while severe viral infections like flu or COVID can lead to serious complications for vulnerable individuals.
