The heart, the brain and high performance

Exploring the balance between desire, reason and conscious control to achieve maximum performance.

High performance is the result of a complex and harmonious interaction between multiple factors including nutrition, physical training, adequate rest and emotional control. Blaise Pascal’s famous quote, “The heart has reasons that reason does not understand.invites us to reflect on the duality between desire and reason, and how both influence our decisions and performance.

In this context, breathing emerges as a powerful and unique tool, as it is the only physiological process that can be controlled both automatically and consciously. By exercising control over our breathing, we can directly influence our emotions, our concentration, and ultimately our performance.

This paper explores the interconnection between the heart and the brain, and how the synergy between desire, reason and conscious control contributes to the achievement of high performance. We will discuss the role of different brain regions, the influence of emotions and memory, and how specific practices can train and optimize our physical and mental capabilities.


The prefrontal cortex is the region of the brain responsible for higher cognitive functions such as planning, reasoning, impulse control, and decision making. It acts as a control center that evaluates information, anticipates consequences, and directs behavior toward the achievement of specific goals.

In the context of high performance, the prefrontal cortex allows us to evaluate situations in a logical and strategic manner, facilitating informed decisions that optimize performance. However, its functioning does not occur in isolation; it is constantly influenced by other brain and emotional processes.

Memory and emotions, processed primarily in the hippocampus and amygdala, respectively, play a crucial role in our actions and decisions. Memory provides a record of past experiences that inform and shape our current responses, while emotions add a layer of meaning and urgency to those experiences.

  • Influence on Decision Making: Emotions can facilitate or interfere with logical reasoning. For example, enthusiasm and confidence can drive motivation and perseverance, while fear or anxiety can lead to indecision or avoidance. The balanced integration of emotions and reason is essential for optimal decisions and consistent performance.
  • Emotional Regulation: The ability to recognize and manage emotions helps maintain focus and mental clarity, especially in high-pressure situations. Techniques such as conscious breathing and mindfulness can help regulate emotional responses and improve cognitive control.

The cerebellum, traditionally associated with motor coordination and balance, also contributes significantly to cognitive and emotional functions. It is involved in the synchronization of precise movements and in the processing of sensory information, which is essential for tasks that require dexterity and perfect timing.

  • Physical and Mental Coordination: The cerebellum helps integrate information from different sensory systems to produce fluid, adaptive movements. It is also involved in motor learning, allowing skills to improve with practice and become automatic over time.
  • Adaptability and LearningBy helping to fine-tune and refine actions based on constant feedback, the cerebellum is critical for rapidly adapting to changes in the environment and performance demands.

Breathing is a unique physiological process that operates both involuntarily and voluntarily. This duality allows breathing to act as a direct bridge between the body and the mind, offering an accessible tool to influence our physical and emotional state.

  • Regulation of the Nervous System: Through controlled breathing patterns, we can activate the parasympathetic nervous system, promoting relaxation and decreasing stress. This is particularly useful for improving concentration, reducing anxiety and preparing the body for optimal performance.
  • Improving Physical Performance: Proper breathing techniques increase the efficiency of oxygen exchange, improving endurance and physical capacity. Nasal breathing, in particular, filters and humidifies the air, and when combined with smell, can enrich sensory perception and adaptive response.

Implementing specific respiratory and olfactory training practices can enhance overall performance by improving both physical and cognitive functions.

  1. Diaphragmatic Breathing: It involves breathing deeply using the diaphragm, which increases lung capacity and promotes a state of calm and concentration.
  2. Pranayama: These yoga breathing techniques, such as alternate breathing and controlled deep breathing, help balance body and mind energy, improving clarity and focus.
  3. Cardiac Coherence: It consists of synchronizing breathing with the heart rate to achieve a state of physiological and emotional balance, optimizing cognitive functioning and reducing stress.
  1. Olfactory Training: Regularly exposing your sense of smell to a variety of aromas and focusing on identifying and differentiating each one improves sensitivity and sensory connection.
  2. Olfactory Mindfulness: Incorporating mindfulness into the act of smelling can deepen the sensory experience and contribute to a more present and receptive state of mind.

While breathing and emotional control are essential components, high performance is based on a holistic balance that includes proper nutrition, structured physical training and restful sleep.

  • Fuel for the Body and Mind: A balanced diet provides the energy and nutrients necessary to sustain intense physical activity and cognitive functions.
  • Synergy with Other Factors: The right foods can improve mood, focus and recovery, working in conjunction with practices like conscious breathing to maximize performance.
  • Skill Development and Resilience: A well-designed training program improves strength, speed, agility and coordination, which are essential for high performance.
  • Integrated Cognitive Training: Incorporating exercises that simultaneously challenge the body and mind, such as strategic sports or activities that require quick decision-making, enhances the ability to respond and adapt.
  • Repair and Regeneration: Adequate rest allows the body and brain to recover, repair tissues, and consolidate learning and memory.
  • Stress Management: Quality sleep and periods of relaxation reduce stress levels and prepare the system to face new challenges with renewed energy.

Achieving and maintaining high performance is a dynamic process that requires the balanced integration of multiple factors. The harmonious interaction between heart and brain, desire and reason, and automatic and conscious control, forms the foundation on which exceptional performance is built.

Conscious breathing stands out as a versatile tool that connects and enhances other essential aspects such as nutrition, physical training and rest. By training and optimizing processes such as breathing and the sense of smell, we can positively influence our emotions, concentration and physical responses.

Ultimately, high performance is not simply the result of working harder, but of working smarter and more consciously, cultivating a deep connection between mind and body, and recognizing the importance of each component in the complex fabric of our human potential.
