Everything you'd
want to ask.
How is Kimba different from aromatherapy?
Traditional aromatherapy delivers the same scent passively at fixed times, without awareness of what the body is doing in real time. Kimba is designed to actively improve sleep by continuously reading biometrics and releasing the right natural scent at the precise moment it is needed during the sleep cycle. The technology works through the olfactory–limbic pathway, the only sensory pathway that can influence the brain during sleep without causing wakefulness. This is responsive, biometrically driven sleep technology — not passive aromatherapy.
Do I need a wearable device for Kimba to work?
No. Kimba works independently using built-in biometric sensors, with no wearable required. For users who already use devices like Oura, WHOOP, Apple Watch, or Garmin, Kimba can integrate existing sleep and biometric data for additional precision.
What biometrics does Kimba monitor?
Kimba monitors sleep architecture, breathing rate, movement, disturbances, light, ambience, and snoring. When integrated with wearables, Kimba can also collect heart rate, HRV, temperature, and additional biometric data.
Will Kimba impact my partner while we sleep?
Kimba is designed to be subtle and precise. It releases scent only at specific moments and for short periods of time, so it does not continuously fill the room like a traditional diffuser. In clinical testing, sleep partners typically reported either not noticing the scent or experiencing a positive effect.
Is it safe to use every night?
Yes. Kimba is drug-free, non-habit-forming, and formulated for long-term daily use. Scents are water-based, plant-derived, and natural-origin formulations developed in alignment with ISO 16128 guidelines.
Are the scents really 100% natural?
Kimba uses natural-origin, plant-derived scent formulations developed in alignment with ISO 16128 guidelines. While ingredients may undergo processing to ensure safety, stability, and performance, every formulation is designed to meet our high standards for natural-origin content, quality, and nightly use. The scents are water-based, cruelty-free, and free from parabens and sulfates.
How frequently do the scent capsules need to be replaced?
Scent capsules are replaced every three months. New capsules are automatically shipped to your home approximately two weeks before your replacement date.
