Understand your nights,not just your hours

Sleep is more than time in bed. HLTH Band tracks your night from your wrist, with no screen and no lights, and shows you how well you rested, not just how long.

Why sleep is worth tracking

Through the night you cycle through light, deep and REM sleep, with short moments awake in between. Health agencies recommend adults get 7 or more hours a night, and say how well you sleep matters as much as how long [1, 2]. Getting enough is linked to better mood, attention and heart and metabolic health [1].

I love how the HLTH Band tracks my sleep without disturbing me. It’s so comfortable I barely notice it at night, and seeing my sleep patterns each morning has helped me build a better bedtime routine.”

Sleepquestions

Do I need to do anything at night?

No. Wear it snug and it tracks in the background.

Why does fit matter?

A loose band gives weaker sleep data.

Will it wake me with lights?

No, there's no screen.

How long does the battery last?

Up to 30 days.

Is it a medical sleep test?

No. It's a wellness device and can't tell you if you have a sleep disorder. Talk to your GP if you're worried.
