Meet the 3 pillars of sleep
Learn how much time you spend in each sleep stage: Light, Deep, REM, and Awake. Deep sleep enables physical recovery while REM sleep helps with memory, thinking and creativity. Do you know how much time you spend in each stage ? Is it optimal ? Kira will help you improve and optimize that.
Circular looks at how much you have actually slept compared to your personal sleeping length needs. Circular calculates your Real Sleep ; the duration of disturbances during your sleep, and gives you a score on how efficiently you slept.
Science shows that sleep must follow a light/darkness cycle, your natural chronotype and that the more consistent you are with your sleep and wake times, the better sleep you'll get. Kira makes recommendations that match up with your chronotype to achieve higher consistency.
