Holistic Wellbeing Benefits of Forest Bathing
A study published in Environmental Health and Preventive Medicine found that people who took part in forest bathing had lower levels of cortisol, a stress hormone, compared to those who spent time in urban environments. The natural setting of forests helps reduce stress and anxiety by lowering blood pressure and heart rates.
One of the amazing physical health benefits of forest bathing is its positive impact on the immune system. A study by Qing Li from Nippon Medical School in Tokyo found that spending time in forests increased the activity of natural killer (NK) cells, which play a crucial role in the body's defence against infections and cancer.
The study attributed this boost in immunity to phytoncides, natural chemicals released by trees. Phytoncides have antibacterial and anti fungal qualities which help plants fight disease.
When people breathe in these chemicals, our bodies respond by increasing the number and activity of a type of white blood cell called natural killer cells or (NK).
These cells kill tumour- and virus-infected cells in our bodies.
Forest bathing can also contribute to improved cardiovascular health. Research published in the International Journal of Environmental Research and Public Health showed that participants who practiced forest bathing experienced significant reductions in blood pressure and heart rate, which are key indicators of heart health.
