World Hormone Day
Thank you to everyone who took part in World Hormone Day 2025! Your energy, creativity and commitment helped make our first global campaign a great success.
Together, we helped raise awareness of the important role hormones play in our health and the steps we can all take to improve hormone health – #BecauseHormonesMatter.
Highlights from the day will be shared here soon. In the meantime, keep spreading the word by sharing and following #BecauseHormonesMatter on social media and using the resources in the Toolkit below.
- 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.
- Join in the conversation on social media using the hashtags #BecauseHormonesMatter and #WorldHormoneDay. Tips here.
- Hold an online or in-person event with your community to promote the small steps everyone can take to achieve good hormone health
- Reach out to your local or national media to encourage coverage of World Hormone Day and explain why hormones matter. Tips here.
- Reach out to “endocrine champions” who can help amplify the message in your community
- Talk to local, national and regional policymakers and organisations who can help drive improvements in research, diagnosis and treatment. Tips here.
We encourage you to use #BecauseHormonesMatter on any endocrine-related awareness days so we can continue to draw attention to endocrine health and disease.
