Light

Light is electromagnetic radiation. Some bands (visible light) are the signal that runs your circadian clock. Other bands (UV, ELF, RF) are noise your biology wasn’t built for.

Visible light — match intensity and spectrum to the time of day.

Time of DayVisual LuxMelanopic EDIColor Temp (CCT)Biological Outcome
Morning (Waking)500–1,000 lx>250 lx5000K–6500KAnchors the clock; resets the 16-hour sleep timer.
Daytime (Work)300–500 lx>150 lx4000K–5000KMaintains focus; suppresses midday melatonin.
Evening (−3h)50–100 lx≤10 lx1800K–2400KWind-down signal; triggers melatonin onset.
Night (Sleep)≤1 lx≤1 lxAmber / RedZero blue light. Maximizes deep sleep (N3).

Invisible EM — minimize non-ionizing exposure, especially during sleep.

CategoryMetricTarget (Wholesome)Target (Sleep/Night)Why it Matters
Ultraviolet (UV)UV Index (UVI)0.0 (indoors)0.0Prevents DNA damage and skin aging.
Magnetic (ELF)MilliGauss (mG)≤1.0 mG≤0.5 mGPrevents interference with melatonin and voltage-gated calcium channels.
Electric (ELF)Volts/Meter (V/m)≤10 V/m≤1.5 V/mLowers nervous system “hum”; aids HRV recovery.
Radio (RF)μW/m²≤1,000 μW/m²≤10 μW/m²Minimizes high-frequency noise from Wi-Fi / 5G.
