What does exercise have to do with creativity and happiness? Where does nature fit in? Research suggests that exercise lifts mood. Harvard psychiatrist John Ratey says, “Working up a sweat could very well be one of the most potent, underused prescriptions we have.” Movement – at least three times per week for thirty minutes triggers mood-enhancing neurotransmitters. Studies have shown that it can compete with antidepressants. Other research has shown that nature (as opposed to concrete) elicits imaginative, fulfilling play in children. Combining nature and movement enhances your chances for creative thoughts and happy moments.
