World Health Day is celebrated every year on April 7 to raise awareness about critical global health issues and encourage individuals to prioritize their well-being. Established by the World Health Organization (WHO) in 1948, the day serves to highlight pressing health concerns and promote healthier lifestyles. The theme for 2026, 'Together for health. Stand with science,' emphasizes the importance of scientific collaboration in safeguarding the health of humans, animals, plants, and the environment. This year's observance marks the beginning of a year-long campaign focused on the role of science in addressing global health challenges. Since its inception, World Health Day has aimed to enhance public understanding of health issues, promote access to quality healthcare, and encourage healthy lifestyle choices.
