    You can also see how you stand up against your peers, people of same age, same gender, comparable game score range, etc.

  • Biomarkers we measure


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


    HRV: heart rate variability is an established indicator of chronic stress toxicity and shows one's power to regulate the bodily expression of stress.

    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 baseline for the assessment of stress toxicity and helps coach you to train your brain and engage the healing and rejuvenating powers of the vagus nerve.

  • Stress

    Taking a few deep breaths when you feel stressed is a at best a quick fix. Stress starts in the brain, which spreads its damaging effects throughout the body. Regular practice of 0.1 Hz breathing replaces the stress nervous response (sympathetic "fight-or-flight") with a relaxation response (parasympathetic, "rest-and-digest"), an antidote for the long-term toxic effects of stress on the brain and body.


    Every cell in your body depends on oxygen for fuel, especially the brain, with respiratory fitness strongly tied to cognitive longevity. However, the metabolism of oxygen, especially under stress, results in toxic byproducts that contribute to accelerated aging, decreasing cognitive and bodily longevity. 0.1 Hz breathing reduces oxygen use and the damaging effects of oxidative stress.


    Research shows that cardiovascular and mental fitness go hand in hand: interventions that are good for the heart are good for the brain. 0.1 Hz breath gaming with Zenytime's revolutionary air controller, the “Puck”, is like a treadmill for your brain, helping improve circulation, reduce blood pressure, decrease heart rate, and enhance RSA (Respiratory Sinus Arrhythmia, a critical measure of heart health).


    Despite the popularity of "brain training" games, studies show that they alone have limited effectiveness on mental functioning. By contrast, 0.1 Hz breathing exercises engage the autonomic nervous system, which enhances brain plasticity and neurogenesis—the birth of new neurons—resulting in long-term changes in both grey and white matter.


    Intimately tied to stress, the immune system response starts in the brain and when overactive results in chronic inflammation, contributing to bodily and cognitive decline. Research shows that regular 0.1 Hz breathing practice triggers an anti-inflammatory from the brain, and can turn on and off genes to regulate the immune system.

  • Pain Management

    An often overlooked component of pain management is managing the stress of pain. Not only does pain cause stress, stress also increases pain with damaging effects on the brain and body. Scientifically designed to build an anti-stress response, Zenytime is an essential component of any multi-modal pain management plan: it promotes consistency and provides new insights by tracking pain biomarkers.

    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.

    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.
