  • Taking a breather: Two-minute 0.1 Hz breathing intervention enhances autonomic balance (*).

    A study released by Zenytime with Cornell University

    Breakthrough Study

    Our study, selected for the 2017 Art & Science of Health Promotion Conference, shows that a brief guided breathing intervention results in immediate healthy autonomic physiology enhancement in twenty participants, ranging in age from 18 to 47. Preliminary data suggest the physiological benefits can extend past the 2-minute practice, consistent with the brain learning a short-term healthy autonomic balance (*) response. Daily practice may increase these physiological benefits to extend throughout the day, from as little as 2 minutes.

  • (*) What is "Autonomic Balance"?


    The Autonomic Nervous System (ANS) regulates all the functions necessary to maintain life.


    The ANS controls the Parasympathetic Nervous System (PNS), also called "rest, repair and rebuild", that stimulates your immune system and optimizes energy management and recovery, and the Sympathetic Nervous System (SNS), a.k.a. “fight or flight”, that “speeds you up” and increases energy expenditure.


    Modern life makes the SNS dominate while the PNS is shut down: "Autonomic Balance" is observed when PNS functions are brought to healthy levels.

  • Your Breath, Brain and Energy Numbers, Decoded:


    Every time you play a Zenytime game, you generate physiological power (bodily functions) and foster neuroplasticity ("brain rewiring") through 0.1 Hz breathing (focused breathing).


    At the end of every game, our algorithms crunch your biomarker data and empower you with color-coded visual shorthands, right in your phone, to get and stay motivated.


    You get your current numbers measured, and related trends are further decoded.

  • The Science behind Zenytime:

    Our solution is based on 20,000+ studies and publications from the most prestigious universities and research centers in the fields of neuroscience, medicine and psychology.

  • Biomarkers we measure:


    HRV: heart rate variability is an established marker of age evolution, a predictor of chronic conditions and a strong indicator of overall health and performance.


    RSA: respiratory sinus arrhythmia is the most accurate real time measurement of the physiological impact of stress, with breathing frequency as a baseline.


    In short, higher biomarker levels indicate optimal ageing, good health and balance, while lower biomarkers shows imbalance and imply bodily malfunction. Professional athletes typically have very high HRV and RSA levels, and track them very carefully to optimize their training schedule.


    We aggregate your biomarker data and turn it into Breath, Energy and Brain Powers for easy, meaningful and elegant everyday tracking.

    0.1 Hz Breathing


    Did you know that Zen monks who reach the highest states of meditation reduce their breathing to about 6 breaths a minute, from 15 and more for the rest of us?


    6 breathing cycles per minute is called "0.1 Hz breathing frequency". Zenytime measures your breathing frequency: it provides a powerful and accurate baseline for the screening of your health and helps coach you to train your brain and engage the healing and rejuvenating powers of the vagus nerve.


    Many clinical studies and applied health programs have demonstrated the outstanding effectiveness of 0.1 Hz breathing techniques, mixed with attention-demanding tasks - e.g. games, to boost HRV and RSA and therefore enhance brain and body performance.



    Zenytime is not intended to diagnose, treat, cure or prevent any disease.

    One month of .1 Hz respiratory training reduces breathing effort and improves both resting pulmonary gas exchange, including enhanced 02 saturation, and exercise performance in patients with chronic heart failure.

    Cardiorespiratory coupling (CRC) is a biomarker of health and may underlie processes of health and disease. CRC deteriorates in sepsis and stress and increases in highly-trained athletes and is enhanced in relaxation and slow-wave sleep. Slow deep breathing enhanced CRC. After only 20 minutes, individuals can show short-term plasticity to strengthen CRC.

    Breathing is associated with widespread brain activity. Comparison of volitional breathing with that controlled by a ventilator during fMRI reveals that breathing activates regions throughout the brain, including subcortical and neocortical regions such as the striatum and frontal lobes.

    Sympathetic hyperactivity and parasympathetic withdrawal may cause and sustain hypertension, with this autonomic imbalance related to reduced arterial baroreflex sensitivity and chemoreflex-induced hyperventilation. Controlled .1 Hz breathing, but not at higher rates, increased baroreflex sensitivity and reduced sympathetic activity and chemoreflex activation.

    Vagally mediated heart rate variability (vmHRV) represents a psychophysiological index of inhibitory control and is associated with emotion regulation capacity. Evidence suggests those with higher resting vmHRV can regulate negative emotions more adequately. Lower resting vmHRV was associated with greater difficulties in emotional regulation, especially a lack of emotional clarity and impulse control.

    Results suggest that positive emotions lead to enhanced HRV, which may be beneficial in the treatment of hypertension and in reducing the likelihood of sudden death in patients with congestive heart failure and coronary artery disease.

    In a randomized, controlled clinical trial, daily sessions of .1 Hz breathing first enhanced heart rate variability (HRV), which was followed by increased baroreflex sensitivity (BRS) and reduced 24-h ambulatory blood pressure in patients with mild hypertension and this effect persisted for the following 6 months.

    Stage 1 essential hypertension patients were randomly divided into the control and other two intervention groups, who were advised to do 3 months of slow-breathing and fast-breathing exercises. Improvement in both the sympathetic and parasympathetic reactivity was associated only in those practicing the slow-breathing exercise



    Philippot, P & Gaetane, C (2010) Respiratory feedback in the generation of emotion. Cognition and Emotion, 2002, 16 (5), 605–627

    Emotions have systematic effects on breathing quality.  Respiratory frequency slowed for joy, and increased for anger and fear. Instruction to practice slow breathing induced significant positive feelings, while faster breathing increased feelings of anger, fear and anxiety. These observations support the notion that respiratory quality plays an important role in emotions.

    Volume: 58, Issue: 1, Pages: 32-37

    The present study was designed to examine the effect of voluntarily slow and fast respiration on the cardiac parasympathetic response to a threat: the anticipation of an electric shock. The amplitude of the high frequency (HF) component of the heart rate variability significantly decreased during the threat in fast and nonpaced breathing groups, whereas it was unchanged in the slow paced breathing group. Results suggest that a slow respiration decreases the cardiac parasympathetic withdrawal response to the threat.

    Ageing is associated with a decline in pulmonary function, heart rate variability and spontaneous baroreflex. Subjects were randomized into a 4-month training program of either stretching (control) or respiratory exercises. Respiratory training improved respiratory function and sympathovagal balance, indicating a regaining of parasympathetic predominance in the elderly.



    Shields, J. W. (2009). Heart rate variability with deep breathing as a clinical test of cardiovagal function. Cleveland Clinic Journal of Medicine.

    Research into heart rate variability (HRV) and respiration over the past 150 years has led to the insight that HRV with deep breathing (HRVdb) is a highly sensitive measure of cardiovagal or parasympathetic cardiac function. This sensitivity makes HRVdb an important part of the battery of cardiovascular autonomic function tests used in clinical autonomic laboratories. HRVdb is a reliable and sensitive clinical test for early detection of cardiovagal dysfunction in a wide range of autonomic disorders.

    Trained musicians allocated to .1 Hz breathing showed significantly greater improvements in high frequency HRV during performance anticipation. Findings indicate that a single session of slow breathing, regardless of biofeedback, is sufficient for controlling physiological arousal in anticipation of psychosocial stress associated with music performance and that slow breathing is particularly helpful for musicians with high levels of anxiety.
