1
Hacking the Limbic System
2
Olfactory Bulb: Olfactory bulb is adjacent to place controlling emotion (Amygdala) and memory (Hippocampus). Stimulates instinct more directly than vision or hearing. Can create Pavlov's dog saying 'Work mode if smell this'
3
AromaTech AroMini BT: Not ultrasonic type, but nebulizer type (Air pressure injection). Mold does not grow because water is not used, pure scent of oil undiluted solution spreads. Can control concentration and time with Bluetooth
4
Pura 4 Smart Diffuser: Small device just plug into outlet. Can load 2 types of scents and switch from smartphone. Full automation of 'Citrus in morning, Lavender at night'
5
Scent Marketing: Luxury hotels and Apple Stores have 'Smell of that place'. Most inexpensive way to make home 'Five Star Hotel' is to change smell

Introduction: Invisible Interior

No matter how expensive furniture is placed, it is ruined if life smell (smell of leftovers or compress) is present. Conversely, even in empty room, if scent of fine wood drifts, it becomes luxury lounge.

Scent is most powerful interior and most powerful productivity improvement tool.

1. The Pro Grade: AromaTech AroMini BT

This is not aroma diffuser. It is “Scent Machine”. Downsized technology used in commercial facilities for home use.

ASIN: B07D3V6Y38

By Cold-Air Diffusion technology, oil is not heated, water is not added, and it is diffused into air as nanoparticles. 'Purity' of scent is different. Can schedule by day of week with app.

No Water, No Mold

Type using water (MUJI etc.) becomes device spreading germs if neglect care. Nebulizer type just sets oil bottle directly. Being maintenance-free is essential requirement for continuing.

2. The Smart Plug: Pura 4

項目	AromaTech (Nebulizer)	Pura 4 (Warming)
Diffusion Method	Air pressure injection (Nano mist)	Low temperature heating (Volatilization)
Scent Type	1 type (Exchange required)	2 types (Auto switch)
Coverage	~100 tatami (Strong)	~20 tatami (Private room)
Price	High ($300~)	Cheap ($50~)

4. The Scent Architecture

Like visual information (Lighting), olfactory information should also be changed by time.

Morning (Awaken) : Lemon, Rosemary, Peppermint. Stimulate sympathetic nerve and wake up brain.
Daytime (Focus) : Sandalwood, Cedarwood, Hinoki. Sustain calmness and concentration.
Night (Relax) : Lavender, Tea Tree, Ylang Ylang. Make parasympathetic nerve dominant and invite to sleep.

By automating this, your body becomes to switch mode arbitrarily with “Smell” as trigger.

Conclusion: Drop Anchor

Just as Ichiro does fixed motion at batter box, we also need “Routine”. However, it is troublesome to do fixed motion every time.

Please make scent Anchor. Moment smell that scent, like Pavlov’s dog, brain enters “Work mode”. If such conditioning can be done, days when not motivated will disappear.
