There is increasing awareness among researchers and health practitioners of the potential health benefits derived from gardening activities. Indeed, previous studies have shown that gardening increases individual's life satisfaction, vigor, psychological wellbeing, positive affects, sense of community, and cognitive function. Reductions in stress, anger, fatigue, and depression and anxiety symptoms have also been documented. In consequence, engagement with gardening has increasingly been recognized as not only a cost-effective health intervention but also a treatment or occupational therapy for those with psychological health issues, so-called "horticultural therapy".

"Bahjat بَهْجَةٍ " means joy or delight. In this verse the gardens are bringing joy or delight. Today gardens are being prescribed as a natural anti-depressant.
How could an illiterate man who lived 1400 years ago have known about the psychological effects of gardens?
