How Many Days Do Allergies Last?
Allergies can last for varying durations, depending on several factors including the type of allergen and the individual's sensitivity. It's not a simple matter of a fixed number of days.

Seasonal Allergies: Seasonal allergies, triggered by pollen, can persist for weeks or even months during pollen season (spring, summer, or fall). One source states that pollen season allergies may last around 6 weeks. [Source: NIH News in Health] Other sources indicate that seasonal allergies can last for several weeks. [Source: Mayo Clinic] The duration depends on the specific pollen in the area and its release timing. For example, tree pollen may start as early as February in some regions and continue through early summer. [Source: ACAAI Public]

Non-Seasonal Allergies: Allergies not tied to a specific season, such as pet dander or dust mite allergies, can last continuously as long as exposure to the allergen persists. Without treatment, symptoms may linger for weeks or months. [Source: Cleveland Clinic]
-
Acute Allergic Reactions: In cases of acute allergic conjunctivitis (allergic reaction affecting the eyes), symptoms typically resolve within 24 hours of exposure to the allergen.

Comparing Allergies to Colds
It's important to distinguish allergies from colds. Colds generally last 3 to 14 days, while allergies can persist for much longer periods. [Source: Mayo Clinic Health System] A key difference is that allergies don't typically cause a fever, unlike colds and the flu. [Source: Family Doctor]
Treatment and Symptom Duration
Treatment can significantly shorten the duration and intensity of allergy symptoms. Options include over-the-counter antihistamines, nasal sprays, and eye drops. A healthcare provider can provide guidance on appropriate treatment based on individual needs. However, this answer focuses solely on the duration of the symptoms and doesn't give medical advice.
