Almost a week on from World Hormone Day, here’s a wrap-up on everything we got up to and why this day is so important.

World Hormone Day marks an important date in our calendar: here at CHEM Trust, we are working hard for stronger regulations on harmful chemicals that can disrupt the normal functioning of our hormones. These are known as endocrine (or hormone) disrupting chemicals (EDCs). Exposure to EDCs has been linked to adverse health impacts such as certain cancers, reduced fertility, and impaired brain development.

EDCs have been found in everyday products including in food, food packaging, clothes, furniture, cosmetics, and cleaning products. While you can take steps to reduce your risk of exposure to harmful chemicals, this burden shouldn’t fall on us as consumers. Instead, current regulations should be doing more to protect us.

This was only the second year of World Hormone Day, following its transition from European Hormone Day in 2025, a shift that reflects the growing awareness and public concern of EDCs.

We marked the day to share a simple message: these chemicals do not belong in products and current regulations aren’t protecting us. We collaborated with the UK Society for Endocrinology to share a series of joint posts on EDCs, how they affect us, how we are exposed and what steps we can take to reduce our risk of being exposed to them. The UK Society for Endocrinology aims to support the global endocrine community and advance education and research to benefit the public.

Another highlight of the day was our interview with Professor Wiebke Arlt, President of the European Society of Endocrinology (ESE). ESE supports the endocrine community through outreach and research, to improve hormone health across Europe and beyond.

Professor Arlt highlighted the scientific evidence on impacts related to EDC exposure: “Many peer-reviewed studies have shown that EDCs impact fertility, endocrine-related cancers, diabetes and obesity, and mental health problems.”.

She commented: “While there are some actions we can take to reduce our exposure, the only real solution to tackle EDCs is a very strict EU regulatory framework that will protect us and future generations from the many health and environmental hazards caused by EDCs.”

Over in Germany, CHEM Trust Europe also spread the word, marking the occasion with an informative post alongside WECF Germany, PAN Germany, and HEJ Support.

There are many other organisations working hard to protect us from EDCs. EDC-Free Europe is a coalition of over 70 groups across Europe, including CHEM Trust, who share this concern. Read the coalition’s seven priorities to protect people and environment from endocrine disrupting chemicals here.
