You Won’t Believe How Hormones Could Be Ruining Your Health—Urgent Call to Action on World Hormone Day!

The European Society of Endocrinology (ESE) has announced that World Hormone Day will return on Friday, April 24, 2026. This global initiative aims to unite the endocrine community in raising awareness about the crucial role hormones play in health and well-being.

World Hormone Day 2026 seeks to improve public understanding of what hormones are, why they matter, and the steps individuals can take to promote good hormone health. The campaign follows the success of the 2025 effort, which reached an estimated audience of over 136 million people worldwide, featuring activities in 40 countries and conducted in 25 languages.

Under the banner of #BecauseHormonesMatter, ESE invites the public, patient groups, national endocrine societies, healthcare professionals, and the media to participate, whether online or through local events, to emphasize the importance of hormone health on a global scale.

"There is still a major gap in public understanding of what hormones are and how people can look after their hormone health," said Professor Wiebke Arlt, ESE President. "Hormones influence almost every process in the body, yet most people only think about them when something goes wrong. World Hormone Day is a chance to change that by raising awareness and sharing practical steps everyone can take towards better hormone health."

To support local, national, and regional activities, ESE plans to provide a comprehensive suite of new and updated campaign materials. These will include social media graphics, posters, videos, and templates that organizations and individuals globally can adapt and use. These resources will be available at the end of January 2026 for anyone to download and utilize.

As the global community prepares for World Hormone Day 2026, it's clear that raising awareness about hormones is more important than ever. Hormones govern a myriad of bodily functions, from metabolism to mood regulation, and understanding them is vital for maintaining overall health. With initiatives like this, there is hope for narrowing the knowledge gap and promoting better hormone health worldwide.
