What are the effects of prolonged UV exposure on cedar’s aromatic oils?
Prolonged exposure to ultraviolet (UV) radiation significantly affects the aromatic oils in cedar wood, altering its scent and therapeutic properties. Cedar’s essential oils, known for their pleasant aroma and natural insect-repellent qualities, degrade under UV light, leading to reduced potency. Over time, this degradation can diminish the wood’s durability and resistance to pests.
UV rays break down the chemical compounds in cedar’s oils, such as thujone and cedrol, which are responsible for its distinctive fragrance. This process not only weakens the wood’s natural defenses but also accelerates weathering. To preserve cedar’s aromatic oils, consider using UV-protective coatings or storing cedar items in shaded areas. Understanding these effects helps in maintaining cedar’s longevity and benefits.
