World Hormone Day will take place on 24 April 2026. This brings together the endocrine community around the world to raise public awareness of what hormones are and why they matter for health and wellbeing.
Under the banner of #BecauseHormonesMatter, we’re sharing the small steps everyone can take to improve hormone health, individually and within our communities.
Please join us!
We are excited to launch the 2026 campaign with a range of materials to help you spread the word about the importance of hormone health - available now in our toolkit. All materials will be available end-January 2026.
- 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 400 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.
This year, we’re focusing on raising awareness of what hormones are, why they matter and the small steps everyone can take towards better hormone health.
Hormones influence almost every process in the body, yet most people only think about them when something goes wrong. World Hormone Day is our chance to change that.
Under the banner of #BecauseHormonesMatter, ESE invites members of the public, patients, patient groups, national endocrine societies, healthcare professionals and media to take part, either online or through local events, to share why hormone health deserves global attention.
Last year, we reached an estimated audience of more than 136 million people worldwide, with activities in 40 countries. With your help, we’d love to reach even more this year!
