Today we're discussing the impact of urban green spaces on mental health. A recent study followed 1,000 adults over five years. Participants who visited parks or gardens at least twice a week reported 20% lower stress levels compared to those who rarely did. Interestingly, the duration of each visit mattered more than the frequency. Even a 10-minute walk in a green area produced noticeable benefits, but the most significant improvements appeared when visits lasted at least 30 minutes. The researchers also noted that the type of vegetation, such as trees versus lawns, had little effect, contradicting earlier assumptions. However, they emphasized that proximity to home was a key factor in encouraging regular use.
