Lavender candles can help with stress, primarily through the principles of aromatherapy.
Here's why and how:
-
Aromatherapy and the Brain: When you inhale the scent of lavender (specifically from a candle made with real lavender essential oil), the aromatic molecules travel directly to your brain's limbic system. This system is responsible for emotions, memory, and mood. The compounds in lavender, particularly linalool and linalyl acetate, are believed to interact with neurotransmitter receptors, leading to calming and anxiolytic (anxiety-reducing) effects.
-
Physiological Effects: Research suggests that inhaling lavender can lead to physiological changes associated with relaxation, such as:
-
Lowered heart rate
-
Reduced blood pressure
-
Regulated breathing
-
Decreased adrenaline and cortisol (stress hormone) levels
-
Activation of the parasympathetic nervous system (the "rest and digest" system)
-
-
Psychological Effects: Beyond direct physiological impact, the familiar and pleasant scent of lavender can:
-
Promote a sense of calm and serenity.
-
Help alleviate feelings of tension, worry, and agitation.
-
Improve mood and promote a positive outlook.
-
Aid in preparing the mind for rest and sleep, which indirectly reduces stress.
-
-
Studies and Evidence:
-
Numerous studies have explored lavender's anxiolytic properties. While much of the research focuses on direct essential oil inhalation or oral administration, the principle of inhaling the aroma (as from a candle) is consistent with aromatherapy.
-
Some studies have specifically looked at lavender aromatherapy's effect on stress and anxiety in various settings, including dental offices, postpartum women, and college students, often showing positive results.
-
A study on adolescents with moderate stress levels suggested that inhaling the scent from lavender soy wax candles for 20 minutes could improve emotional states and enhance cognitive function.
-
Important Considerations for Lavender Candles and Stress Relief:
-
Quality of Essential Oil: For true aromatherapy benefits, the candle should be made with pure lavender essential oil, not synthetic "fragrance oils." Fragrance oils are chemically created scents that mimic lavender but do not contain the therapeutic compounds found in the natural essential oil.
-
Concentration: The amount of essential oil released from a candle can vary, and its effectiveness might depend on the concentration and duration of exposure. For optimal effects, ensure the scent is noticeable in your space.
-
Environment: While the lavender scent helps, creating a peaceful and quiet environment around the candle will enhance the stress-reducing experience.
-
Complementary Tool: Lavender candles are a wonderful complementary tool for stress management. They are not a substitute for professional medical or psychological treatment for severe anxiety or stress disorders.
In summary, lighting a lavender candle can contribute to a relaxing atmosphere and, through the principles of aromatherapy, can indeed help alleviate feelings of stress and promote a sense of calm.
