Hope molecules: exercise releases brain-boosting myokines
Exercise releases myokines, enhancing mental health and resilience
The discovery of ‘hope molecules’ is hailed as the ‘most exciting find of the last decade’ by health psychologist Kelly McGonigal, PhD. These chemicals, secreted by the body under specific conditions, offer a promising insight into the interplay between physical activity and mental health.
Kelly McGonigal, a health psychologist and author, shared insights on ‘hope molecules’ during a podcast with Rich Roll. She recounted coming across the term in a scientific paper and noted its underutilisation. These ‘hope molecules’ refer to small proteins known as myokines.
According to McGonigal, muscles act like an endocrine organ. When muscles contract during any form of movement, they release chemicals like myokines into the bloodstream. These chemicals benefit various bodily systems, including heart health and immune function, and some can even combat cancer cells. More intriguingly, these proteins have significant effects on the brain.

McGonigal elaborated, describing how activities like walking, running, or lifting weights trigger muscle contractions that release these proteins. They travel through the bloodstream, cross the blood-brain barrier, and act as anti-depressants. They enhance brain resilience to stress, boost motivation, and aid in learning from experiences.
For those wondering if these chemicals can be obtained in another way, McGonigal clarified, “The only way to get these chemicals is by using your muscles. This is part of how we become our best selves; we have to use our muscles.”
Myokines earned the nickname ‘hope molecules’ because studies found that exercise could shield rodents from depression and PTSD even after severe trauma. This suggests that these molecules provide hope even in challenging times.
McGonigal believes movement should be framed as an ‘intravenous dose of hope.’ She concludes, “It’s something you can choose to do to powerfully influence your mental health and resilience, and every time you move, you’re doing that.”
