Pulsio Halo
Benefits backed by research
Halo gives you bright white light in the morning and red light in the evening, timed to your body clock. Here's what that does for you, and the research behind it.
- 3,000+published papers on light therapy
- 1984first light therapy trial for winter mood
- 116people in one sleep-lab study of evening light
-
Supports deeper sleep
Wind down in the evening and sleep more deeply. In a study of 20 athletes, 30 minutes of red light each night for two weeks improved sleep quality and melatonin levels, compared with no light.1
-
Helps set your body clock
Light is the strongest signal your body clock gets. Researchers found the eye has a dedicated sensor for it, most sensitive to blue-green light, which tells your body when the day has started.2
-
Helps lift winter low mood
Brighter mornings for darker months. Research into bright light exposure highlights its role in supporting your body's natural daily rhythm.
-
Gentle light to wind down
Ordinary room light before bed held back melatonin, the sleep hormone, in 99% of people.4 Halo's red light sits at 660nm, far from the light that does that, so you can read and relax.2

The science behind Halo
Over 40 years of research into light, sleep and mood.
Light therapy lamps were first studied in 1984. Since then, researchers have published thousands of papers on how light shapes our sleep, our mood and the body clock.
Evening · Red light
Red light and sleep quality
In a 2012 study of elite athletes, 30 minutes of red light each night for 14 days improved sleep quality and melatonin levels compared with no light.
