Sounds about right - nature and wellbeing

From Medical Express:

Two hours a week is key dose of nature for health and wellbeing
Spending at least two hours a week in nature may be a crucial threshold for promoting health and wellbeing, according to a new large-scale study.

Research led by the University of Exeter, published in Scientific Reports and funded by NIHR, found that people who spend at least 120 minutes in nature a week are significantly more likely to report good health and higher psychological wellbeing than those who don't visit nature at all during an average week. However, no such benefits were found for people who visited natural settings such as town parks, woodlands, country parks and beaches for less than 120 minutes a week.

Makes perfect sense - moving out of Seattle was a great boost to my emotional state and physical health. Living in a city is stressful - I would never move back.
