This is actually great news. It means even when circumstances, possessions, or people in our lives aren’t exactly as we’d like them to be, there are simple ways we can increase our happy brain chemicals and alter our moods. Here’s how you can do the same. Endorphins are released after both aerobic and anaerobic exercise. In one study, as little as 30 minutes of walking on a treadmill for 10 days in a row was sufficient to produce a significant reduction in depression among clinically depressed subjects. Exposure to bright light, especially sunshine, is one way to increase serotonin. Exercise and happy thoughts also stimulate production of this chemical. Some research has found that a higher intake of tryptophan-heavy foods, relative to other foods in the diet, may do the trick as well. Volunteering has been shown to increase dopamine as well as have other long-term health benefits. And some research has even found that it only takes thoughts of loving kindness to bring on the dopamine high. This hormone provides a multiple whammy of warm fuzzies, by stimulating dopamine and serotonin, while reducing anxiety. To get your hit of oxytocin without popping ecstasy, give someone you love a cuddle. Even a pet will do. If you’re like me, happiness may at times feel like the unachievable holy grail of emotion. But luckily, our brains and bodies are constantly undergoing complex chemical processes that we can affect with our daily actions. Once we understand how our feel-good hormones and neurotransmitters work, we may be able to trigger them more easily than we realized. Related reads:
