Cognition is involved in acquiring knowledge through thought, experience, and senses, which is fundamental to human interaction and encompasses perception, attention, memory, reasoning, and decision-making. These cognitive functions influence academic success and daily life. Oxygen intake is critical for cognitive function as it supports Adenosine triphosphate production and neurotransmitter synthesis. Reduced oxygen levels, or hypoxia, can impair the brain, particularly the hippocampus and prefrontal cortex, leading to cognitive dysfunction. Breathing plays a vital role in cognitive function by influencing the Autonomic Nervous System (ANS). Focused inhalation techniques, such as slow and deep breathing, stimulate the Parasympathetic Nervous System (PNS), resulting in increased vagal tone and improved heart rate variability physiological markers associated with enhanced cognitive functions, including attention, memory, and executive function. Activation of the PNS also facilitates the release of acetylcholine, a neurotransmitter essential for synaptic plasticity, learning, and memory consolidation, while simultaneously reducing stress and promoting relaxation. The brainstem controls breathing patterns and adjusts them based on metabolic needs. The medulla oblongata and pons are key brainstem structures that regulate breathing. Focused inhalation techniques modulate brain activity, increasing alpha wave activity, which is linked to relaxation and concentration. Neuroimaging studies show that deep breathing and controlled breathing can enhance activity in the prefrontal cortex and anterior cingulate cortex, which are areas associated with attention and emotional regulation. Regular practice of focused breathing can enhance neuroplasticity and increase gray matter density in brain areas involved in learning and memory. Therefore, the rationale for this study is to investigate the potential of focused inhalation techniques as a practical tool to enhance cognitive function by promoting relaxation, improving neuroplasticity, and supporting emotional well-being.
