Circadian rhythm Alignment

Circadian rhythm (the inner rhythm of our body), plays a crucial role in regulating our daily cycles, including sleep-wake rhythms, body temperature and hormone release. You can look at it as a internal biological clock, ensuring that everything runs smoothly for optimum performance.


These rhythms include the physical, mental and behavioural changes that we go through every day over a 24-hour cycle. Although mainly influenced by light and darkness, they are also affected by other factors such as diet, stress, physical activity, our social environment and temperature.


Virtually all living things, From animals and plants to micro-organisms, have their own circadian rhythm. In humans, this works in a more complex way, with almost every tissue and organ having its own rhythm, all tuned to the natural cycle of day and night.

How does Ultrahuman help understand and optimise circadian rhythms?

Ultrahuman measures and analyzes various aspects of the circadian rhythm to help users better understand their biological clock and adjust their lifestyle for improved health and well-being. The Ultrahuman app provides insights into the following phases:

Circadian dead zone

While exposure to light and physical activity has other varied benefits, exposure during this window has minimal impact on your circadian clock.

Phase delay zone

Screen exposure during this window is suboptimal for health. Relaxation methods like listening to music and non-sleep deep rest are highly beneficial.

Phase minima zone

This refers to the probable window of your sleep where you experience minimum core temperature. Exposure to light and activity during this window is detrimental to sleep quality and recovery.

Phase advance zone

Movement and light exposure during the phase advance window help with shifting your circadian clock to an earlier time in the day.
