MCS Summer 2025 – Summary

This update from Kathy’s MCS/ES Helpline highlights major international progress and practical advice for people affected by Multiple Chemical Sensitivity (MCS) and Fragrance Sensitivity.

🌐 International Developments

• UN Recognition: MCS was officially recognised by the United Nations in 2025, thanks to advocacy by Canadian organisations.
• Global Conference: The first International MCS Conference focused on scientific legitimacy, diagnosis, treatment, and policy change.
• Advocacy Goals: Integration of MCS into public policy, healthcare, housing, employment, and accessibility standards.

🧴 Understanding Fragrance Sensitivity

• Fragrance is a common trigger for MCS and can also be a standalone condition.
• Fragrances contain hundreds of chemicals, mostly petroleum-based VOCs, often undisclosed due to trade secrecy.
• Fragrance is found in thousands of consumer products, including those not labelled as scented.

🛡️ Managing Exposure

1. Fragrance-Free Products: Label terms like “unscented,” “de-scented,” and “natural” can be misleading. Cross-contamination is common.
2. Air Purifiers: Can help but have limitations. Choose models carefully based on chemical removal, noise, light, and air movement.
3. Masks: Useful in public spaces. Options range from fabric masks with chemical filters to full respirators.
4. Buying Goods: Online shopping may reduce exposure. Be cautious of scented packaging and reused boxes.
5. Treatments: Some benefit from low-dose immunotherapy or isopathy.
6. Explaining to Others: Communication can be difficult. Tact, preparation, and written support can help. Consider practical accommodations for visitors.

🏥 Health and Social Impact

• Fragrance exposure is linked to asthma, migraines, eczema, and other health issues.
• Surveys show public support for fragrance-free environments.
• Fragrance-free policies exist in parts of Canada and the U.S., often as accessibility measures.
• Fragrance Sensitivity is recognised as a disability in some countries.
• National Fragrance-Free Day is promoted annually in June by the Asthma & Allergy Foundation in Scotland.
