International Left-Handers Day is celebrated annually on August 13 to honor the unique challenges and strengths of left-handed individuals, who constitute about 10-13% of the global population. Established in 1976 by Dean R. Campbell, the day aims to raise awareness about the difficulties left-handers face in a predominantly right-handed world, such as using right-handed tools and dealing with social stigma. Celebrations highlight the diversity and individuality of left-handed people, who are often associated with creativity and adaptability, thanks to their brain's structure and function. Reports indicate that left-handed individuals may suffer from higher rates of certain health issues, including allergies and sleep disturbances. The day encourages inclusivity and calls for better product design to accommodate both left and right-handed users. It serves as a reminder of the historical prejudices faced by left-handed people, including persecution in the past.
