In December 2014, the UN General Assembly adopted a resolution declaring June 21 as the International Day of Yoga, first celebrated in 2015 with tens of thousands of participants worldwide. The date, the summer solstice and longest day of the year in the Northern Hemisphere, was chosen for its symbolism of light and balance across many cultures. Yoga is an ancient practice originating in India that combines physical postures, breathing techniques, and meditation. Studies have shown its benefits in reducing stress and anxiety, improving flexibility and physical strength, and supporting overall mental well-being. The day encourages people of all ages and backgrounds to experience yoga as a holistic, healthy way of life, and raises awareness of its physical and mental benefits through group sessions and free classes held around the world.
