Thanks for joining me for another edition of the SerenityThroughSweat blog. Today I want to talk about galanin, what it is and some of the many ways it helps us.
Galanin is a neuropeptide, which is fancy word for a protein produced by neurons. (don’t worry I had to look it up because it sounded more like one of king arthur’s knights to me). Galanin is found in many different parts of our brain as well as our GI tract.
A recent article in the Journal of Neuroscience, shows an increased galanin level (derived from unfettered access to cardiovascular exercise) was correlated with a conferred resilience to stress in mice.
Two groups of mice were observed after a stressful event (foot shock). The respective galanin levels were measured in each group, with the experimental group having access to a running wheel in their cage and the control group having none. After three weeks there was a correlation between the elevated galanin levels, the amount of time exercising, and the degree of stress resilience, in the group of mice who used the running wheel. (After building in the first week they were averaging 10-16km per day, if you needed some motivation for your own running)
The test then went on to elevate galanin levels in otherwise sedentary mice and the observed the same stress resilience effects. It is obvious but worth stating that people are not mice, but we do have very similar galanin receptors. This experiment shows that repeated cardiovascular exercise increases galanin, and increased galanin helps us deal with stress.
Doing further research on galanin, I found this article in Nature, which shows that increased galanin levels are responsible for regulating aggression toward pups in male mice, and increasing their tendency towards parental behavior.
I’ve always felt that I’m a better father, husband, and overall person after a good sweat session. There are obviously multiple chemicals in play there, but galanin has a big role to play. This is especially true as stress levels have been elevated these past few months, as has time with my sons without daycare.
Increasing galanin levels seems like a great thing to do no matter what, but an especially great thing with all the stresses of Covid life, and the best way to do that is some good old fashioned SerenityThroughSweat.
Thanks for joining me, stay safe and stay sweaty my friends.
