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. Will you join us?
- 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 public 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.
Participants can choose whatever themes and activities are most relevant to their community, using the #BecauseHormonesMatter message.
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!
ESE will promote World Hormone Day on social media and traditional media in the run-up to the event and on the day itself.
Here are a few ways you can join in:
-
Promote the small steps towards better hormone health in your online or in-person events
-
Reach out to local or national media to encourage coverage of World Hormone Day
-
Invite endocrine champions in your community to help share the messages (this doesn’t have to be a celebrity or public figure – it could be a nurse, young scientist, patient representative, or any active member of your network who’s passionate about hormone health)
-
Encourage policymakers to help support the campaign by sharing World Hormone Day messages through their own channels and networks.
Please tell us about your activities so we can help to promote them and feature them in our highlights video. (Here’s last year’s video for some inspiration.)
