“Hope can begin in your muscles.” ~ Kelly McGonigal, PhD, from The Joy of Movement
Our muscles do much more than help us move. When they contract, they release chemical messengers called myokines into the bloodstream, sending signals throughout the body, including to the brain. Researchers are discovering that these signals may influence mood, stress regulation, inflammation, and brain health. One myokine, irisin, has been linked to pathways involving BDNF (Brain-Derived Neurotrophic Factor), a protein that supports the growth, health, and adaptability of our brain cells. Think of BDNF is a type of fertilizer for the brain, helping our brain cells grow, connect, and adapt.
This is why I love psychologist and researcher, Kelly McGonigal’s idea of “hope molecules.” It isn’t the scientific name for one particular molecule. It is a beautiful way of describing the connection between our muscles, our bodies, and our brains. When we move, our muscles are communicating with the rest of our body.
Movement doesn’t have to be a hard workout. A walk, stretching, dancing in the kitchen, taking the stairs, or simply stepping outside and moving your body can create this conversation.
The next time you feel stressed, stuck, sad, or disconnected, ask yourself: What kind of movement might help me move out of this funk? Then turn on your favorite song, grab your hairbrush, and sing and dance to your heart’s content. Give yourself permission to move and notice how you feel afterward.
Maybe that shift you feel is your body doing what it was designed to do. Your muscles are sending signals, your brain is responding, and your whole system is getting the message: keep going. Perhaps that is the real beauty of the “hope molecules.” They remind us that our bodies are not just along for the ride. Our muscles are active participants in helping us adapt, feel, and move forward.
Stretching alongside you,
