Fly fishing changes one’s brain. According to research, 20 or more specific brain centers of the unconscious brain may be called into action at a single time during an average person’s day.
Separate centers deal with the basics – metabolism (heart, lungs, circulatory system), sensory input (touch, temperature, pressure, pain) – as well as perception, memory, learning, thought and language. The brainstem gets into the act by correlating past memories and events with the present situation to suggest a possible plan of action. Each center analyzes incoming information to make changes to address external influences.
It’s all designed to reach a desired outcome. If that desired outcome is achieved, something called the “hypothalamic satiety center” will receive signals of satisfaction. Unfortunately, in today’s busy world, that satisfaction can be very short in duration.
This same research suggests that when fly fishing, less than 10 brain centers may be active. When one first takes up fly fishing, high expectations could bring a few more brain centers into action. However, over time, the combination of that anticipation as well as affirming memories of previous fly fishing successes, in theory, increases the duration of signals sent to the satiety center in the hypothalamus.
This could be why a few weeks ago my wife told me that I need (her emphasis) to go fishing. Maybe my brain centers have been too active.
There’s plenty of commentary about fly fishing as therapy. This gentle sport is integral to the well-known Project Healing Waters Fly Fishing and Casting for Recovery programs. It’s used in other, lesser-known therapy programs for drug addiction and depression.
Surely it’s a good form of self-therapy.
Water is a key part of this therapy. The sound of moving water is soothing. The sound as it tumbles over rocks, through vegetation or over a fall. Moving water lends freshness to the air, making it cool and moist. Animals lured to the water add to the chorus. Birdsong echoes off the water, the beat of insect wings hums in the background, frogs croak. If one’s lucky, a breeze will rustle the leaves and grasses.
This restful backdrop becomes part of the alertness, concentration and stealth required of fly fishing; a meditative state that directly increases the likelihood of hooking a fish. On the stream, waiting is necessary.
Fly fishing was mindfulness before it had a name.
