Welcome to Hanu Health Certified Coach, where you can learn to make a real difference in the lives of clients struggling with stress, anxiety, depression, and other mental health concerns.

Our certification programme is designed to give you the skills you need to understand heart rate variability (HRV) and use biofeedback to help your clients self-regulate their emotions and physiology.

By understanding HRV, you’ll be able to identify patterns that may indicate stress, anxiety, or other issues. With biofeedback, you’ll teach your clients how to regulate their breathing and other physiological responses to reduce stress and improve their overall well-being.

Our programme is based on cutting-edge research and advanced techniques, so you can be confident that you’re receiving the most up-to-date training available.

Plus, when you become a Hanu Health Certified Coach, you’ll enjoy continued support from a community of like-minded professionals who are dedicated to making a positive impact on mental health and well-being.

With his unique blend of expertise in breathwork, movement, and mindfulness, Gray is committed to helping his clients achieve optimal health and well-being. 

Dr Jay Wiles

Dr Jay Wiles

Dr. Jay T. Wiles is a licensed clinical health and performance psychologist with board certification in heart rate variability biofeedback and peripheral biofeedback.

He works as a leading consultant in psychophysiology to health influencers, professional athletes, executives and high performers. He has pioneered a new and innovative means of using heart rate variability (HRV) and respiratory training as both diagnostic indicators of the dynamic nature of the human stress response and for improving mental health outcomes.

He has an extensive history of working with top-performing athletes in the PGA, LPGA, MLS, MLB, ATP, and WTA.


Breathwork and HRV are closely related because breathing patterns have a significant impact on HRV.

HRV refers to the variation in time between consecutive heartbeats, which is controlled by the autonomic nervous system (ANS). The ANS is responsible for regulating many involuntary functions in the body, including heart rate, breathing, and digestion.

Breathing patterns can influence HRV. When you take slow, deep breaths, you activate the parasympathetic nervous system, which is responsible for relaxation and can increase HRV. On the other hand, when you take rapid, shallow breaths, you activate the sympathetic nervous system, which is responsible for the “fight or flight” response and can decrease HRV.

Breathwork techniques can be used to improve HRV by teaching clients how to regulate their breathing patterns to activate the parasympathetic nervous system and promote relaxation. By improving HRV, clients can experience a range of benefits, including reduced stress, anxiety, and depression, improved sleep, and better overall health and well-being.

Beyond Breathwork

While breathwork is often considered the most popular method for improving heart rate variability, there are many other techniques that can also help. Here are some of the effective ways to improve heart rate variability that are often overlooked:

Spending time in nature has been shown to have a positive effect on heart rate variability. Exposure to natural environments can reduce stress and improve overall mood and well-being. Being in nature can activate the parasympathetic nervous system, which can lead to an increase in heart rate variability.

Hot and cold therapy is another effective way to improve heart rate variability. Alternating between hot and cold temperatures can stimulate the body’s sympathetic and parasympathetic nervous systems, leading to an increase in heart rate variability. Additionally, sauna use has been shown to increase heart rate variability and promote cardiovascular health.

Regular moderate-intensity exercise is a well-known way to improve heart rate variability. Exercise can increase cardiovascular fitness and reduce stress on the body, leading to an increase in heart rate variability.

Mindfulness meditation is another effective technique for improving heart rate variability by reducing stress and increasing parasympathetic activity. Mindful meditation is a type of meditation that involves focusing one’s attention on the present moment, without judgment. The goal of mindful meditation is to cultivate a sense of awareness and acceptance of one’s thoughts, emotions, and physical sensations, rather than trying to suppress or control them.

Finally, consuming omega-3 fatty acids can also improve heart rate variability. Omega-3 fatty acids, which are found in fish and other sources, have been shown to reduce inflammation and promote overall cardiovascular health, leading to an increase in heart rate variability.

In conclusion, breathwork is not the only way to improve heart rate variability. Spending time in nature, using hot and cold therapy, regular exercise, mindfulness meditation, and consuming omega-3 fatty acids are all effective ways to increase heart rate variability and promote overall health and well-being.
