1. Choose the Right Product

Prioritize "safe, low-irritation, and easy-to-fix" options:

• Prefer flameless types: Vent-mounted aromatherapy (clips to air vents), solid fragrance balms (in metal/plastic cases), or reed diffusers (with sealed bottles for cup holders). These have no fire or leakage risks.

• Avoid flame-based products: Never use scented candles or incense—open flames may cause fires, and smoke pollutes air and obscures vision.

• Skip high-concentration essential oils: Pure essential oils evaporate too quickly, leading to dizziness or respiratory irritation. Opt for car-specific diluted oils, or add 1-2 drops of diluted oil to a diffuser stone in the cup holder.

2. Proper Installation & Usage

• Safe placement:

◦ Vent aromatherapy: Clip to passenger or rear vents (avoid driver’s front vents to prevent distraction or olfactory fatigue).

◦ Dashboard aromatherapy: Place in corners, away from airbags (to prevent flying during deployment) and instrument panels.

◦ Cup holder/storage: Secure reed diffusers or balms here to avoid spills (liquid may damage interiors).

• Control concentration:

◦ Use less than at home (in-car space: 3-5 m³): Insert 2-3 reeds, open balm lids halfway initially. Let new aromatherapy air out for 10 minutes outside the car first.

• Fragrance selection:

◦ Long trips/fatigue: Energizing scents (lemon, mint, rosemary) to stay alert.

◦ Daily commutes/traffic: Calming scents (low-concentration lavender, cedarwood, bergamot) to reduce anxiety.

◦ Avoid strong sweet scents (jasmine, rose, musk)—they may cause dizziness in enclosed spaces.

3. Key Precautions

• Regular checks:

◦ Liquid/reed diffusers: Check for leaks weekly (clean and replace if oil stains appear). Replace when fragrance fades.

◦ Solid balms: Cool melted balms in shade, or choose heat-resistant beeswax-based ones.

• Special scenarios:

◦ After summer heat exposure (over 60℃): Ventilate first—high temperatures speed up evaporation and may release harmful substances.

◦ With infants/pets: Use low-irritation options (unscented/light citrus) and keep windows slightly open. Avoid for cats (sensitive to tea tree/mint oils).

• Emergency response:

◦ Stop using if feeling dizzy/nauseous—ventilate and rest.

◦ Rinse skin with water if oil contacts it.
