Circadian rhythms - Embedded within the genes of us

Time dictates our lives to a profound degree. Not only does the progress of time navigate us to be on time, but it also guides your body and brain to do its tasks throughout the day. Inside each and every one of us there is a mechanised clock system, it’s called circadian rhythm (circa about, diem a day). In fact, everything that’s alive on this earth has it too.

Your circadian rhythm rules your sleep-wake cycle. It gets you up in the morning even if your alarm clock doesn't go off, it makes you energised and productive, tells your organs to be active, and your brain to glisten with brilliance.These biological instructions mark the passage of approximately 24 hours.

Until just a few decades ago, scientists suspected that humans have evolved away from internal circadian rhythms because of our modern lifestyles. 74% of the world’s population now inhabits cities, and we, the urban dwellers, no longer rely on the natural day and night light rhythm for our sleep-wake cycle. We walk the illuminated streets at late hours of the night, work in offices with little exposure to natural light and lounge in front of our computer and phone screens until superhuman hours. While this is great for the autonomous urban dweller, it’s less great for our circadian rhythm and wellbeing. 

Colour, intensity, timing and duration are important factors for our circadian system and health. Not getting the right type of light at the correct time of the day comes with the cost of hindering your wellbeing – causing health problems related to sleep, alertness and physical strength, amongst other illnesses. Not receiving enough light during the day makes you feel tired, with low concentration levels and slow metabolism. Equally, too much blue light in the hours before bedtime maintains your energy levels high and can cause severe sleeping disorders.

The mechanics, electronics and algorithms of the LYS wearable are designed to mimic the non-visual photoreceptors in our eyes. The LYS app understands your light diet and how you can improve your habits by calculating your age, gender, chronotype and usual wake up and bedtime hours.

Together, the LYS wearable and app work to guide you to the exact light composition your body needs throughout the day. Making you sleep better, improving your alertness and concentration levels, balancing your metabolism activity and boosting your mood. In a natural way.
