My name is Glyn Blackett and I teach people skills in managing panic, hyperventilation (over-breathing),
anxiety and stress. I use a range of science and technology based tools to create comprehensive and
In a panic attack you experience intense, spiralling anxiety, along with thoughts of impending
catastrophe and loss of control. Panic affects the body - there are typically physical symptoms
such as pounding heart, chest pain, nausea, dizziness, numbness or tingling, and most importantly
difficulty breathing or hyperventilation.
While cognitive therapy methods may help, in the heat of the moment you can't think your
way out of panic. The key to resolving panic and anxiety is the ability to reverse these
physiological changes happening in the body. This is a skill that can be learned or trained.
Biofeedback is an ideal tool for learning mind-body flexibility.
How Biofeedback Helps Panic and Anxiety
Biofeedback measures and feeds back in real time physiological changes associated with anxiety
and panic. That gives you the basis for understanding panic and learning to break the spiral
so that the body can relax again.
Panic, Hyperventilation and Breathing Biofeedback
The key physical change is to breathing. Anxiety instinctively triggers fast, shallow breathing,
which reduces blood flow and oxygen delivery to the brain, and especially the outer cortical
regions associated with cool, rational control. This lack of oxygen triggers a chain reaction
leading to further over-breathing.
In my clinical experience over-breathing often goes unrecognised. In extreme cases oxygen delivery
to the brain is reduced by up to 60% - but when it is only 10-20% you don't necessarily notice
it. But we can measure it with a biofeedback device (a capnometer).
Breathing Training With Biofeedback
I use a number of different biofeedback modalities including capnometry biofeedback, EMG or
muscle tension biofeedback and HRV biofeedback to develop your mind-body skills, or your
ability to create the physiological conditions for calm, clear focus and thinking, plus
emotional positivity. Biofeedback is an ideal partner for mindfulness, an ancient method of mind training.
Resolving the Preconditions of Panic and Anxiety
Several factors may contribute to underlying vulnerability to panic and anxiety including:
- Poor nutrition leading to problems with blood sugar regulation which affects brain function.
- Adrenal fatigue or adrenal dysregulation - the adrenal glands produce stress hormones such
as adrenalin and cortisol. Note adrenal fatigue is a stress condition not a medical problem.
- A hypersensitive Sympathetic Nervous System (associated with the "fight or
- Learned patterns of poor breathing - chronic hyperventilation - which is typically unnoticed.
- Nutrient deficiencies such as vitamin B6, and magnesium, which can lead to neurotransmitter
imbalances in the brain.
My approach involves testing for the preconditions for panic and anxiety, using both
office-based stress assessment and
functional laboratory testing for optimal brain performance.
This creates the basis for a comprehensive (multi-level) and personalised solution.
Besides breathing training and mind-body skills training using biofeedback, I can recommend dietary
and lifestyle changes, and targeted nutritional supplementation to address underlying vulnerabilities.
More About the Therapy Process
Initially we'll work together to establish the most appropriate individual goals,
based in part on the results of my online symptoms questionnaire, which generates an
automated report. Nothing is imposed - we'll work with whatever methods will suit
your wishes. For those who can get to my office
in York, 3 to 8 one-hour sessions is the typical range for panic and anxiety.
If you can't get to my office easily, we can still work together effectively
using online or telephone-based coaching, online training materials, and
biofeedback device rental for home use.
If you'd like to meet, either in person or by telephone, in order to discuss
the options further, please contact me to arrange
a no-obligations free initial consultation.
