118 of the 370 participants were involved in home gardening. Many studies have also found that being in the sunshine increases serotonin levels (the brain chemical associated with mood), and that being in the sun while gardening might give your brain an extra dose of happiness. Gardening has many other benefits as well. It is known to be good for one's mental health and wellness, improve cognitive function, increase memory retention, reduce stress, provide a sense of purpose and fulfillment, and more. In fact, research shows that people who gardened reported greater life satisfaction than those who did not. Furthermore, gardening is becoming increasingly popular around the world. The number of people participating in gardening programs or activities increased by 17 percent between 2007 and 2017. This represents nearly 100 million people worldwide. In conclusion, gardeners are likely happier people!
