Manage sleep with your breath!

Cardiac coherence exercise is very difficult to do without breathing guidance! Sophrology's breathing exercises are inspired by Yoga Pranayama. Here are 4 reasons why Zen Uyku is not just a simple Sophrology breathing exercise:

1. Zen Uyku shows the optimal pace for you: 6 breaths per minute to rest you and rebalance your autonomic nervous system. Each breath is 50% longer than the breath taken to tire you out. Trying to track your own breathing independently forces you to think and count, which causes performance anxiety and thus significantly delays sleep.

2. A person who is not used to meditation has a maximum attention span of thirty seconds, so you can get lost in your thoughts very quickly and forget to do the breathing exercise. Zen Uyku's light signal synchronized with your heart rate keeps you on track!

3. Synchronizing one's breathing with a slow and steady pulse of light, thanks to the pulse data from the wristband, has a hypnotic effect, similar to watching a pendulum, helping you relax quickly

4. Zen Uyku helps you to reduce and calm the flow of your thoughts by focusing your attention on an external point (the light signal) without having to concentrate on your breath - the emphasis is paradoxically placed on keeping you awake.

We have no doubts about the effectiveness of simple breathing exercises, but we are less sure of our users' ability to do them on their own ;).

The color blue was chosen after much testing based on the generally accepted perception that blue is calming. High doses of blue light may help wake you up by inhibiting the secretion of melatonin, but Zen Uyku does not. The light signal reflected on the ceiling is at its maximum intensity and has a very low intensity (less than 1 lux) for someone lying in bed (about 60 lux at a distance of 50 cm) compared to the relatively strong intensity of a computer or television screen. In addition, the exposure time (from 8 to 20 minutes) is low. The effect of Zen Uyku on the circadian rhythm is therefore almost zero, or in any case too low to delay falling asleep and counteract the positive effects described above. Therefore, the luminous halo is actually more like color than light.

Zen Uyku works great for jetlag or irregular sleep stages.

Yes, by breathing long enough (6 breaths per minute) in the rhythm of Zen Uyku, you will stimulate the baroreflex, a small physiological mechanism that helps restore balance to the autonomic nervous system. Thus, you will quickly move from the waking state (activation of the sympathetic nervous system) to the resting state (activation of the parasympathetic nervous system), which is the same state you are in during digestion: somewhat sleepy. In this case, you will be much less sensitive to your stress, your metabolism will slow down, the release of neurotransmitters that keep you awake should be stopped, and sleep will be very close. On the other hand, you will be distracted from your thoughts by focusing on the state projected onto the ceiling by Zen Uyku. Some people try to "force" sleep: they try to fall asleep at all costs, creating stress that prevents them from falling asleep. By keeping your eyes open to follow the light pulse, you no longer try to fall asleep and, paradoxically, increase your chances of falling asleep. In psychology this is called paradoxical intent, scientific studies have shown its usefulness in the treatment of sleep-onset disorders.

Yes, just touch the surface of Zen Uyku to turn it back on, just as you do when you want to fall asleep. The routine is the same as at the beginning of the night. Synchronizing your breathing with the pulse data from the wristband with the luminous halo pulsating in a slow and regular rhythm has a hypnotic effect (the phenomenon is similar to staring at a pendulum). So you can relax and fall asleep after a few minutes.

Yes, we have lots of references on this subject (we recommend checking them out). The breathing routine recommended by Zen Uyku is very simple and should be done gradually and calmly. Zen Uyku is especially well suited for people who are afraid of the dark (many in children and the elderly). Zen Uyku can be used from the age of 6 years.

Results can vary with individuals, but while most people fall asleep easily within the first 20 minutes, most fall asleep even before the end of the 8-minute cycle. Our users say that thanks to Zen Uyku, they fall asleep 2.5 times faster on average. And please remember, the more you use Zen Uyku, the better results you can expect – you may even not need it anymore.

Yes, of course Zen Uyku will automatically shut down at the end of your routine based on data from your Wristband.

Zen Uyku works on two levels:

1. By breathing at a very slow pace (about 6 per minute), you stimulate baroreflex, which helps regulate your autonomic nervous system.

2. Focusing your attention on exercise allows you to set aside unwanted thoughts.
