Biohacking is the practice of using science, technology, and lifestyle interventions to optimise health, performance, and well-being. Often viewed as the art and science of "hacking" biology, biohacking combines principles from fields such as nutrition, neuroscience, genetics, and exercise physiology to help people improve their physical and mental health. Biohacking can be as simple as taking supplements to enhance cognitive performance or as complex as implanting devices to monitor physiological responses.
