Green healing power
WHEN shinrin-yoku -or ‘forest bathing’ — was originally practised in the early 1980s it was based on a belief that being among the dazzling green forests of Japan would be good for people’s health.
Then a Forest Therapy Study Group created by Dr Qing Li, associate professor at the Nippon Medical School in Tokyo, proved it could boost the immune system, and lower cortisol, adrenaline, anxiety, depression, anger and blood pressure.
Trees heal in many ways and Dr Qing Li found that one powerful element is their natural aromatherapy.
Trees release natural oils known as phytoncides that protect them from bacteria, insects and fungi — and studies have shown that exposure to essential oils lift depression.
