A NEW LIGHT PARADIGM

Redefine waking up

Decades of research on dawn/dusk simulation have shown that - if done right - artificial dawn bears groundbreaking potential to improve mental health and well-being.

However, current commercial wake-up lights lack critical characteristics of the "naturalistic" dawn signal from the clinical trials.

Zeitgeber brings the gold standard in dawn/dusk simulation to your bedroom

It is the first accurate reproduction of a naturalistic dawn simulation - enclosed in an elegant bedside lamp for everyday use.

BENEFITs

What to expect from Naturalistic Dawn

Make the morning your ally

Be a natural early riser

Naturalistic dawn – unlike any commercial wake-up light – has been shown to shift your circadian rhythm.

Improve your mood in winter

Naturalistic dawn has shown comparable mood improvements to 10,000 lux bright light therapy.

Fall asleep easier

An advanced circadian rhythm and low-blue evening light leads to healthy melatonin levels that support sleep onset.

Invest in your long-term health

Circadian health, as facilitated by steady dawn/dust simulation, is a known factor for longevity.
