John Mayer's Heart & Armor: Beyond Music

John Mayer has committed substantial personal funds and energy to advancing veterans' health, particularly concerning post-traumatic stress disorder (PTSD).

Through his nonprofit, Heart and Armor, Mayer has invested roughly $5 million of his own money into scientific research and programs. This initiative began in the late 2000s after a visit to Camp Lejeune, deeply impacting him with the experiences of wounded soldiers.

Heart and Armor's research, co-led with executive director Gerard Choucroun, focuses on tangible studies. Current promising projects investigate whether treating insomnia after trauma can prevent PTSD and explore the link between PTSD and the brain's waste-clearance system during sleep.

Mayer frames PTSD not merely as a mental health issue but as a physical injury. He believes this perspective makes the problem observable and interruptible, thereby energizing efforts toward solutions and reducing stigma.

His dedication extends beyond celebrity, with the nonprofit securing grants based on scientific merit rather than Mayer's fame. He aspires for Heart and Armor's work to stand independently, proving its worth with or without his name attached.

Concurrently, Mayer is actively involved in developing his first album since 2021's *Sob Rock* and revitalizing Chaplin Studios, a historic Hollywood lot he purchased in 2024.
