How it works

Your body clock runs on light.

Your body runs on a natural internal clock. Seasons, screens and stress can easily throw it off balance. Halo works like natural daylight, helping your body wind down melatonin (the sleep hormone) in the morning and supporting serotonin, which helps lift your mood.

Morning Bright light when your body expects daylight helps reinforce wakefulness and alertness.

Evening Warmer 660 nm red light gives you a gentler light environment as the day winds down.

Consistency Because Halo is wearable, your light routine can happen while the rest of your life carries on.

The science behind Halo

Over 40 years of research into light, sleep and mood.

Light therapy was first described for winter depression, known as seasonal affective disorder (SAD), in 1984. Since then, researchers have published thousands of papers on how light shapes our sleep, our mood and the body clock.
