In 1982, Japan's Ministry of Agriculture, Forestry, and Fisheries coined the term Shinrin-yoku — forest bathing — to describe the practice of spending time among trees for health benefits. What began as a public health initiative has since become one of the most robustly researched wellness practices in the world.
The science behind why forests make us feel better has direct implications for what we burn in our homes.
The Science of Forest Bathing
Researchers at Nippon Medical School, led by immunologist Qing Li, conducted a series of landmark studies on the physiological effects of forest exposure. Their findings include:
- Significant reduction in cortisol (stress hormone) after 2 hours of forest walking vs. urban walking
- Lower blood pressure and heart rate in forest environments
- Increased NK (natural killer) cell activity — a key marker of immune function — lasting up to 30 days after a forest trip
- Reduced anxiety and depression scores across multiple population groups
The mechanism behind many of these effects appears to be phytoncides — volatile organic compounds released by trees that humans inhale in forest environments. The primary phytoncides in coniferous forests are terpenes found in pine, cypress, and cedarwood: alpha-pinene, beta-pinene, limonene, and terpineol.
Pine Essential Oil
Primary compounds: Alpha-pinene, beta-pinene, limonene, bornyl acetate
Aromatherapeutic profile:
Alpha-pinene — the compound that makes pine smell like pine — is one of the most researched phytoncides:
- Research shows alpha-pinene inhalation reduces anxiety and produces relaxation responses in the nervous system
- Studies indicate alpha-pinene has anti-inflammatory properties when inhaled
- Your brain uses a chemical called acetylcholine to form memories and stay alert. An enzyme called acetylcholinesterase constantly breaks it down. Alpha-pinene appears to slow that breakdown — meaning more acetylcholine stays active in the brain for longer. This may be part of the reason pine forests leave people feeling mentally clearer.
- Pine aroma is consistently associated with perceived cleanliness and reduced stress in environmental psychology research
Best used for: Stress relief, focus work, any time you want the psychological reset of outdoor air without going outside.
Cypress Essential Oil
Primary compounds: Alpha-pinene, delta-3-carene, limonene, cedrol
Aromatherapeutic profile:
Cypress shares significant terpene content with pine while adding its own distinct profile:
- Respiratory support — cypress has been used in traditional medicine for respiratory conditions; its terpene profile supports airway opening similar to eucalyptus
- Grounding and calming — in aromatherapy practice, cypress is consistently categorized as grounding and emotionally stabilizing
- Circulatory support — traditional aromatherapy applications include cypress for improving circulation and reducing feelings of heaviness
The addition of cypress to a pine blend adds complexity and depth — it's the difference between a single pine tree and a forest canopy.
Best used for: Stress relief, moments of emotional heaviness, respiratory support, meditation.
Cedarwood Essential Oil
Primary compounds: Cedrol, alpha-cedrene, beta-cedrene, thujopsene
Aromatherapeutic profile:
Cedarwood brings the deepest, most grounding note of the three:
- Sedative properties — cedrol, the primary compound in cedarwood, has demonstrated sedative effects in animal research, with human studies showing reduced heart rate and increased slow-wave sleep
- Anxiety reduction — research shows cedarwood inhalation reduces anxiety behaviors and promotes calm
- GABA-ergic activity — like lavender, cedarwood compounds appear to interact with GABA receptors in the nervous system — the same receptors involved in relaxation and sleep
- Grounding anchor — in perfumery and aromatherapy, cedarwood is the quintessential base note — the deep, warm, woody anchor that makes a blend last and feel substantial
A study published in the Journal of Alternative and Complementary Medicine found cedrol inhalation produced significant reductions in autonomic nervous system arousal — measurable via skin conductance and heart rate — consistent with a genuine relaxation response.
Best used for: Evening relaxation, meditation, sleep preparation, stress recovery.
Recreating Forest Bathing at Home
The research on forest bathing phytoncides gives us a clear picture of what's happening when we burn a pine, cypress, and cedarwood candle: we're introducing the primary terpene compounds that trees release into forest air — the same compounds Qing Li's research identified as responsible for immune activation, cortisol reduction, and anxiety relief.
You're not getting the full forest bathing effect from a candle — there's no sunlight, no ground to walk on, no humidity from leaves. But the olfactory component — the phytoncides themselves — is genuinely present.
Research on odor-evoked psychological effects consistently shows that scents associated with positive environments produce measurable benefits even when the environment itself is absent. The smell of pine activates the same neural pathways whether you're in a forest or a living room.
The cumulative effect of regular use: Several forest bathing researchers have noted that even brief daily exposure to forest environments (or forest-scent environments) produces stress recovery benefits that compound over time. A 30-minute candle session in the evening isn't a substitute for a forest walk — but it's a meaningful daily stress reduction practice that costs nothing extra once the candle is lit.
Best rooms for this candle: Living room, home office, meditation space, bedroom — anywhere you want the psychological reset of nature without leaving home.
This coconut wax candle is particularly suited for: People who live in urban environments, those who work high-stress jobs, anyone who feels most themselves outdoors and wants to bring that quality inside.
