What is biofeedback?

Biofeedback - a training method for self-regulation of unconscious processes in your own body.

Biofeedback is a process in which you learn to gain better awareness and control over your body functions, using tools that provide "feedback" on the activity of these body systems. 

Biofeedback tools provide immediate feedback on your responses to stress and anxiety, thus helping you to recognize and ultimately influence the relationship between psychological processes and physiological changes in your body. 

With regular practice, you can learn how to adjust your response to stressful events and optimize your well-being.

How it works

When we are stressed or happy, our bodies reflect this by:

  • Increasing the activity of the sweat glands
  • Increased electrical conductivity of the skin
  • Increased heart rate
  • Rapid and irregular changes in heart rate
  • Fast, irregular breathing

The role of biofeedback

Biofeedback uses visual displays of stress levels to guide you in using rhythmic, uniform, and relaxed breathing techniques to calm responses to "Fight or Fright" stress that builds up after intense periods of mental fatigue. 

Biofeedback allows us to control our biology and control our stress level.

What physical values ​​do we measure?

At Biohacking Performance we use state-of-the-art methods for monitoring and evaluating three major nervous systems that send us information about your body.


Voluntary nervous system 


  • Electromyograph

Autonomic nervous system


  • Temperature 
  • The level of electrical conductivity at the skin level 
  • Hear Rate Variability
  • Sweating from the pile
  • Pulse

Central nervous system 


  • Electroencephalograph 



How does breathing affect heart rate? Breathing activates your vagal nerve, which descends from the brain into the carotid sheath to the diaphragm. The vagal nerve slows the heart rate.


A response to stress of any kind (difficult conversation with someone, driving in heavy traffic or stress before speaking in public) changes your heart rate regardless of variations in breathing, leading to irregular changes.


Instead, when breathing is uniform and natural, you get smooth heart rate waves that are associated with maximum health and performance.


Optimal breathing for relaxation


Breathing affects heart rate: As you inhale, your heart rate accelerates naturally. As you exhale, your heart rate slows naturally. Slow and relaxed breathing creates slow and fine changes in heart rate.

In the way music students use a metronome to set their rhythm, we use a stimulator to keep breathing even and regular. Biohacking Performance integrates respiratory stimulants into all games and environments to help modulate your breathing.
