World Hormone Day resources to use year-round >>
On 24 April 2026, ESE and the endocrine community around the world united to raise public awareness of the importance of good hormone health – #BecauseHormonesMatter
A better understanding of what hormones are and why they matter can encourage healthier lifestyle choices, support early detection of endocrine-related disease and achieve better health for all.
A huge THANK YOU to everyone who joined us in marking the day!

World Hormone Day returns on 24 April 2027 – put the date in your diary! We'll publish a new 2027 toolkit with campaign materials nearer the time, but you can start thinking now about how to take part:
- Follow @BecauseHormonesMatter on Instagram and @WorldHormoneDay on Facebook.
- Think about any 'hormone champions' in your network who can help amplify the message in your community.
- Consider if you'll need to book venues and speakers for online or in-person events about hormone health.
- Plan how you might use local or national media to encourage coverage of World Hormone Day and explain why hormones matter. Tips here.
- Start thinking about how you might reach out to local, national and regional policymakers that can help drive improvements in research, diagnosis and treatment. Tips here.
- Endocrinology is the study of hormones, which are essential for health and wellbeing. When hormones are out of balance or fail, this can lead to the development of chronic diseases such as diabetes, thyroid disorders, cancer, osteoporosis and obesity, and other health challenges such as infertility.
- There are also more than 440 rare endocrine conditions that affect millions of people worldwide, but often go undetected.
- Despite scientific progress and increased awareness in some areas, there’s still a lot more that can be done. World Hormone Day is an opportunity for us to work together to put hormones in the spotlight.
- ESE published 10 Recommendations for Good Hormone Health as an Annex to the Milano Declaration. These recommendations are a great place to start when thinking about small steps to take.
