CHUNCHEON, Oct. 27 (Korea Bizwire) — Visitors seeking the health benefits of South Korea’s forests may want to plan their outings carefully.
A new study shows that the concentration of phytoncides — antimicrobial compounds emitted by trees and believed to promote wellness — peaks in June, particularly during afternoon hours.
The Gangwon Province Institute of Health and Environment said Sunday that it measured phytoncide levels at five locations in the Solhyang Arboretum in Gangneung between June and August.
Concentrations were highest in June, when tree activity is strongest, ranging from 5,314 to 8,716 nanograms per cubic meter. Levels remained elevated in July and August, though at lower ranges.
Levels above 1,000 nanograms are considered high, according to forestry researchers.
Phytoncides are natural substances that help plants ward off pathogens and, when inhaled by humans, are associated with reduced stress and improved immune responses. Their release varies by season and time of day.
A separate 24-hour monitoring effort found that the optimal time for forest bathing also shifts as summer progresses: between 3 p.m. and 6 p.m. in June, and from 6 p.m. to 9 p.m. in July and August.
“Afternoon visits are recommended to maximize the therapeutic benefits of the forest,” said Shin In-chul, head of the provincial health research institute. He added that continued monitoring would support public health efforts and highlight the restorative value of Kangwon’s forests.
The findings come as more South Koreans embrace “forest healing” practices to counter stress and improve well-being.
