90 PER CENT of Bradford residents make efforts to keep their homes "extremely clean", according to the team behind an allergy medication.

Researchers Allevia suggested that the city's cleaning efforts are "primarily aimed at preventing mould," and that higher humidity levels and damp conditions in the region might exacerbate mould growth compared to in other locations.

Allevia calculates that 10 per cent of Bradford's residents suffer from mould-related allergies.

Sunderland, in contrast, was the UK city deemed most allergic to mould, with 43 per cent of residents supposedly allergic.

St Albans and Warrington were in joint second place at 33 per cent.

The study also found that almost 1 in 5 Brits report being allergic to mould, making it the UK's fourth most common airborne allergy.

The number increases among Generation X, with 57 per cent of the age group actively cleaning more often and trying to control moisture levels in their homes.

There are currently 2 million people living in homes with significant damp or mould issues, according to Directgov, which equates to 3 to 4 per cent of residences.

Mould exposure can trigger severe respiratory issues for those allergic, such as asthma attacks, chronic sinus infections, and other allergic reactions.
