Meet Harmoni
Beautifully designed to sit naturally in any home, Harmoni delivers clinical-grade light therapy without looking clinical.
Addressing Sundowning at the Source
Harmoni targets the underlying circadian dysfunction that causes sundowning symptoms, not just masking them, but addressing the biological mechanisms directly.
Agitation & Restlessness
Dysregulated cortisol and circadian confusion create physiological stress
How Harmoni Helps
Precisely tuned blue light (470-480nm) re-entrains the SCN, stabilizing cortisol rhythms and reducing stress-induced agitation by up to 89%
Sleep Disturbances
Melatonin production is disrupted, leading to difficulty falling and staying asleep
How Harmoni Helps
Late morning and early afternoon light therapy strengthens circadian amplitude, promoting natural evening melatonin rise and extending sleep by an average of 2.5 hours
Confusion & Disorientation
SCN degeneration causes loss of temporal awareness. The brain can't tell what time of day it is
How Harmoni Helps
Daily light exposure provides powerful temporal cues to the damaged SCN, helping restore internal sense of time and reducing disorientation
Anxiety & Fear
Circadian disruption triggers inappropriate stress hormone release and emotional dysregulation
How Harmoni Helps
Circadian stabilisation normalises neuroendocrine function, reducing anxiety triggers. Red light (630nm) provides additional calming without disrupting sleep signals
The Science Behind Each Feature
Understanding how Harmoni's technical specifications translate to therapeutic benefit.
Dual-Wavelength Precision
The Mechanism: Blue light maximally stimulates melanopsin, containing retinal ganglion cells (ipRGCs), the direct pathway to the SCN.
Clinical Benefit: Provides the strongest possible circadian entrainment signal to the damaged SCN, even when retinal pathways are compromised by dementia.
Circadian-Optimized Timing
The Mechanism: Light exposure in the mid-day biological phase advances the circadian rhythm, helping to prevent the evening desynchronisation that triggers sundowning.
Clinical Benefit: Targets the critical window when circadian intervention has maximum therapeutic effect, before symptoms emerge.
Calibrated Intensity Control
The Mechanism: Therapeutic light levels (>250 lux) achieve circadian entrainment without causing discomfort or glare.
Clinical Benefit: Delivers clinical-grade light therapy while remaining comfortable for extended use, accommodating individual sensitivity.
Extended Exposure Duration
The Mechanism: Circadian photoentrainment requires sustained light exposure to accumulate sufficient photon dose to the SCN.
Clinical Benefit: Ensures adequate light 'dose' reaches the circadian system, maximising therapeutic effect while remaining practical for daily use.
Stay close, even when you can't be there
Harmoni is designed to support the person using it and the people who care about them. Through the Glow app, authorised family members and caregivers can check that Harmoni is being used, manage approved settings remotely and receive helpful information about changes in routine or the home environment.
