How Aromatherapy Works
Aromatherapy works through the olfactory nerves, directly impacting the limbic system in the brain, specifically areas like the amygdala and hippocampus involved in emotional processing. This stimulation encourages the release of moodstabilizing neurotransmitters such as serotonin and dopamine. For SAD patients, aromatherapy provides a nonpharmaceutical way to offer sensory stimulation to the brain, improving mood, alleviating fatigue, and fostering a calm mental state.
Application Methods
Aromatherapy can be used through diffusers, warm compresses, and massage oils. At home or in a work setting, using a diffuser or scented candles releases essential oils into the air, creating a suitable ambiance that helps SAD patients gradually feel the calming and uplifting effects of these scents.
