The science behind Luma³

When it comes to stress, our body has two modes.

When we are stressed our body activates our "fight or flight" mode via our sympathetic nervous system. Spending too long in this mode can leave us feeling exhausted and lead to long term health complications.

Luma³ guides us back into the "rest and digest" mode by using conscious breathing to activate the parasympathetic nervous system.

I’m very excited about the Luma³. It offers a gentle nudge to pay attention to what we all do – breathe. Sleeping is a natural function, and so is breathing. They can both impact one another. The Luma³ provides a simple way to support both.

In my work with organisations, I see Luma³’s potential as both an employee wellbeing and productivity tool. By using Luma³ as a timer in Hourglass mode to aid the timing of focused work periods and then practicing conscious breathing in break periods, you can reset and step out of ‘always-on’ working patterns.

We all need more moments of calm

A message from our founder

Hello, I'm Michael and I created Luma³ (pronounced Lumacube) because I know it will be helpful to so many to have an easy way to access conscious breathing techniques. These techniques have helped me personally for over 20 years.


I have a background in design engineering and business, though I have happily spent 10 years of my life in education as a leader of pastoral care and wellbeing. Conscious breathing has not only boosted my own wellbeing and mental health but has also hugely benefitted many young people and adults to which I have taught these simple techniques.

The business behind Luma³ will be supporting young people's mental health through direct support in schools. So, when you buy Luma³, you're not only investing in your own wellbeing but helping to build resilient young minds.


Every 55 minutes Luma³ gently illuminates to let you know it's time for some conscious breathing

Supporting young minds...

For every ten Luma³ sold, one will be provided free to a school, college or university to support young people's wellbeing and mental health.

We call this the "10 to 1 Initiative", each Luma³ will arrive with a set of digital resources, ready to implemented as part of the curriculum which teach the benefits of conscious breathing and other, easy mental health self care strategies.

Profits from sales of Luma³ will also be used to directly subsidise or fund mental health interventions in schools.
