[Allergic diseases in the indoor environment]

Area of Science:

• Environmental Health
• Allergology
• Indoor Air Quality

Context:

• Global increase in allergic diseases over 30 years.
• Over 50% of allergies linked to indoor environmental allergens.
• Increased indoor humidity and reduced air exchange due to energy conservation measures since the 1970s.

Purpose:

• To highlight the significant role of indoor allergens in the rising prevalence of allergic diseases.
• To identify key indoor allergen sources and contributing environmental factors.
• To emphasize the need for prevention and source elimination in managing indoor allergies.

Summary:

• Common indoor allergens include those from cats, dust mites, and molds, often found in mattresses and textiles.
• Poorly maintained air conditioning systems contribute to microbiological contamination.
• Increased pet ownership, particularly cats, exacerbates indoor allergen exposure.
• The correlation between specific indoor allergen concentrations and disease onset remains largely unknown.

Impact:

• Underscores the importance of addressing indoor environments for public health.
• Informs strategies for preventing and treating indoor air allergies.
• Highlights the need for further research into allergen-disease correlations and effective interventions.
