In safety notes, which essential oil is noted to cause insomnia?

• A. Mint oil
• B. Rosemary oil
• C. Lemon oil
• D. Geranium oil

Answer: (A)

Some essential oils can affect sleep by either stimulating or calming the nervous system. Mint oil is known for its stimulating properties due to menthol, which can increase alertness, heart rate, and overall arousal. When used near bedtime, this stimulation can make it harder to wind down, leading to insomnia for sensitive individuals. Rosemary shares a similar tendency to stimulate mental activity, lemon can be uplifting and energizing, while geranium tends to be more calming and balancing. Because mint oil most clearly and consistently promotes wakefulness, it is the one noted to potentially cause insomnia.
