ADHD and How Anyone Can Improve Their Focus features Andrew Huberman (PhD) unpacking how attention works in the brain—and what throws it off. He walks through the science behind focus, from dopamine to neural circuits, and looks at tools that can help, including exercise, diet, supplements, and technology-based interventions. Whether it’s jumping rope or managing screen time, Huberman shares a wide mix of options for people with ADHD or anyone who just wants better focus day to day.
