If You’re Happy and You Know it… Grow Some Neurons!

Posted on

We’ve all heard and intuitively know that when you’re happier, you’re healthier. Joseph Campbell has been saying for ages — follow your bliss. Abraham-Hicks says it too — the most important thing is that you feel good now. Well, I recently came across a tidbit of research that tells me science is finally catching up!

I read this excellent article recently that explains how scientists have proven that serotonin — the hormone associated with happiness — helps rats grow new brain cells. Specifically, when a certain serotonin-receptor is stimulated, the rats grew new neurons in their Enteric Nervous System (ENS). The ENS is a complex system of about 100 million neurons that inhabit the “gut” which supervise digestion and have intricate ties with the central nervous system (the brain and spinal cord). This alone is quite revolutionary, that we have neurons, essentially brain tissue, in our gut and not just our brain. In fact, we have two “small brains” — one in our gut and one in our heart, which account for the nervous, fluttery or heart-poundy feelings we can get at times. As a fetus develops, all the neurological tissue starts out in one area, a sort of tube, which extends out to form clusters which eventually become the brain, the heart and the gut. The exact role of these “small brains” is unknown, but I can’t help but wonder if it has something to do with our intuition. This is another excellent article about the heart’s rhythms and how the heart is a “small brain.”

The results of the study on the rats was published in The Journal of Neuroscience in August of 2009. So this isn’t even cutting-edge research (it’s just new to me). Yet so many of us are taught that if you drink too much, you’ll kill brain cells, and that you were only born with a certain number of them and if you kill them, you’ll never get them back. This is only half true — you can kill brain cells but you can also grow them back. If you are happy, your brain is healthier, and you are able to regrow new brain cells and the health of your existing cells is maintained. Plus, you can grow neurons in places other than your brain, and keep your gut and heart healthy.

Rack it up with all the other evidence that being happy is the best way to be! Nourish your playful spirit! Don’t let anything get you down. You are 100% in charge of your happiness and you can never blame circumstances when you’re miserable.

Note: I don’t approve of animal testing in general, but these studies on rats are pretty revolutionary. I hope the rats were treated well.
