Itchy eyes, dry mouth or a tickly throat? Perhaps it is the start of the hay fever season or could you be one of up to 20% of the British public who experience the symptoms of an indoor allergy*?

Indoor allergies can easily be mistaken for hayfever and the symptoms are similar to a cold. During the first few hours, you may sneeze, get a runny or blocked nose, and experience dryness in your throat or eyes.

You could begin to feel tired and generally unwell if you continue to be exposed to the allergen. Depending on the allergen, your symptoms could persist for weeks and may be intermittent, which is why they are often mistaken for more common allergies such as hay fever.

What are the Causes of an Indoor Allergy?

There are many common allergens within the home or office environment, such as dust mites, mould, dust from dead skin flakes or pet hair, and can be found in household chemicals, such as cleaning products. Dust mites benefit from warmth and humidity meaning their numbers increase during the spring and summer.

Like hay fever, when someone with an indoor allergy comes into contact with the allergen they present typical allergy symptoms, ranging from sneezing or blocked nose to red and itchy eyes.

How to treat an indoor allergy?

Treating indoor allergies is the same as hayfever, over the counter remedies such as antihistamine tables and nasal decongestants can help relieve your symptoms.
