Looks good to me. Mentally refreshing when awake and stimuating regenerative phases when sleeping.

Modification of sleep-waking and electroencephalogram induced by vetiver essential oil inhalation.

Abstract
BACKGROUND:

Essential oils (EOs) have been claimed to modulate mental functions though the most of data were obtained from subjective methods of assessment. Direct effects of EO on brain function remained largely to be confirmed with scientific proof. This study aimed to demonstrate quantifiable and reproducible effects of commercial vetiver (Vetiveria zizanioides) EO inhalation on sleep-waking and electroencephalogram (EEG) patterns in adult male Wistar rats. The experiments were conducted during November 2013 - February 2014.
MATERIALS AND METHODS:

The following electrode implantation on the skull, control, and treated animals were subjected for EEG recording while inhaling water and vetiver EO (20 and 200 µl), respectively. Fast Fourier transform was used for analysis of EEG power spectrum.
RESULTS:

One-way ANOVA analysis confirmed that vetiver EO inhalation significantly increased total waking and reduced slow-wave sleep time. Moreover, EO inhalation decreased alpha and beta1 activity in both frontal and parietal cortices and increased gamma activity in the frontal cortex. Changes in these frequencies began almost from the start of the inhalation.
CONCLUSION:

These data suggest refreshing properties of vetiver EO on electrical brain activity and alertness.

Odors enhance slow-wave activity in non-rapid eye movement sleep.

Abstract

Most forms of suprathreshold sensory stimulation perturb sleep. In contrast, presentation of pure olfactory or mild trigeminal odorants does not lead to behavioral or physiological arousal. In fact, some odors promote objective and subjective measures of sleep quality in humans and rodents. The brain mechanisms underlying these sleep-protective properties of olfaction remain unclear. Slow oscillations in the electroencephalogram (EEG) are a marker of deep sleep, and K complexes (KCs) are an EEG marker of cortical response to sensory interference. We therefore hypothesized that odorants presented during sleep will increase power in slow EEG oscillations. Moreover, given that odorants do not drive sleep interruption, we hypothesized that unlike other sensory stimuli odorants would not drive KCs. To test these hypotheses we used polysomnography to measure sleep in 34 healthy subjects (19 women, 15 men; mean age 26.5 ± 2.5 yr) who were repeatedly presented with odor stimuli via a computer-controlled air-dilution olfactometer over the course of a single night. Each participant was exposed to one of four odorants, lavender oil (n = 13), vetiver oil (n = 5), vanillin (n = 12), or ammonium sulfide (n = 4), for durations of 5, 10, and 20 s every 9-15 min. Consistent with our hypotheses, we found that odor presentation during sleep enhanced the power of delta (0.5-4 Hz) and slow spindle (9-12 Hz) frequencies during non-rapid eye movement sleep. The increase was proportionate to odor duration. In addition, odor presentation did not modulate the occurrence of KCs. These findings imply a sleep-promoting olfactory mechanism that may deepen sleep through driving increased slow-frequency oscillations.

The biggest issue with inhaling essential oils is actually getting it to your lungs.

1. Aromatherapy devices/humidifiers often emit a vertical stream or do not adequately disperse the essential oils into the air.

2. If you tried to directly put it into an inhaler, most essential oils melt plastic on contact. Hence the thick glass bottles most EOs come in.

3. And if you tried to ingest it, most EOs are damaging to mucous membranes.

That’s not my experience. Why not dilute it in alcohol and use it like a perfume? You’ll get a lot of the molecules into your lungs by passively inhaling them then

Isn't opening an EO bottle sufficient?

I have one opened next to me and I can smell it. Maybe all components do not "evaporate" in the same way though.

That’s correct. You coils put 1-2 drops in a piece of cloth and take a sniff every now and the. (A corona mask too)
