Two hours a week in nature – forest, garden, park or beach – can improve your sense of wellbeing and physical, mental and emotional health. This is across the board, but especially true for those living in high income, urban societies. Living in urban areas with greater access to green space is associated with fewer cases of obesity, diabetes, heart disease, severe asthma and mental distress. The fascinating thing about this specific statistic is that it does not matter how you spend this time. The benefits kick in whether they are short or long walks or even gentle visits to green spaces. Two hours a week, only 17 minutes a day.
