Cedar Oil: Aromatherapy and Wood Protection in One Natural Product
Cedar oil serves two distinct purposes in the sauna world, and it's important not to confuse them. As an essential oil for aromatherapy, it adds a warm, woodsy fragrance to your sauna sessions. As a wood treatment product, it protects and conditions cedar sauna wood, helping it resist moisture, maintain its color, and last longer. Different products, different applications, same source material.
Quick Answers
What is cedar oil used for in a sauna?
Cedar oil serves two separate purposes: as an essential oil for aromatherapy, added to bucket water and poured on stones for a warm, woodsy scent, and as a wood treatment product that penetrates cedar benches and walls to resist moisture, maintain color, and prevent cracking. They are different products, even though they share a source material.
How much cedar essential oil should I add to sauna water?
Add 2 to 5 drops of cedar essential oil to your bucket water, then pour it on the stones as usual. The steam will carry the fragrance through the room. Cedar blends well with lavender, pine, and bergamot if you want to mix scents.
Can I use any wood oil on sauna benches?
No, interior sauna surfaces like benches, walls, and backrests require food-grade or sauna-rated natural oils only. Synthetic stains, varnishes, and polyurethane finishes should never be used inside a sauna because they off-gas toxic fumes when heated. Exterior surfaces have more treatment options since they don't face direct body heat.
How often should cedar wood treatment be applied?
One or two applications per year is typically sufficient for interior sauna surfaces. Apply the oil to a clean, dry, unheated sauna with a cloth or brush, let it soak for 15 to 30 minutes, wipe off excess, and allow 24 hours to cure before the next session.
Does cedar oil have a relaxing or energizing effect?
Cedar oil is calming and grounding rather than stimulating, which sets it apart from energizing oils like eucalyptus. Many people find it complements the parasympathetic nervous system activation that a sauna session already promotes.
Cedar Oil as Aromatherapy
Cedar essential oil has a warm, grounding, slightly sweet scent that pairs naturally with the smell of a cedar-lined sauna. It's calming rather than stimulating (unlike eucalyptus, which energizes). Many people find cedar oil helps promote relaxation and complements the parasympathetic nervous system activation that sauna already triggers.
Use it the same way as any sauna essential oil: add 2-5 drops to your bucket water and pour on the stones. The steam carries the cedar fragrance throughout the room. Cedar blends well with other essential oils like lavender, pine, and bergamot.
Cedar Oil as Wood Treatment
Cedar wood treatment oils are different products from essential oils, though they may share some compounds. These are formulated to penetrate and protect wood surfaces. Applied to cedar sauna benches, walls, or exterior surfaces, treatment oil helps:
- Resist moisture - oil fills the wood pores and reduces water absorption
- Maintain color - untreated cedar grays over time; oil preserves the warm reddish-brown tone
- Prevent drying and cracking - keeps the wood supple through heat cycles
- Repel insects - cedar's natural insect-repellent properties are enhanced by oil treatment
For sauna interior surfaces (benches, walls, backrests), use only food-grade or sauna-rated natural oils. Synthetic stains, varnishes, or polyurethane finishes are never appropriate inside a sauna - they off-gas toxic fumes when heated. Exterior sauna surfaces have more treatment options since they're not exposed to direct body heat.
Application Tips
Apply cedar wood oil with a cloth or brush to clean, dry surfaces. Let it soak in for 15-30 minutes, then wipe off any excess. The sauna should be unheated during application and given 24 hours to absorb and cure before the next session. One or two applications per year is typically sufficient for interior surfaces.
