The Mindfulness in Motion (MIM) protocol offers a pragmatic Mindfulness Based Intervention (MBI) on-site, for persons working in chronically high-stress work environments that significantly increases resiliency and work engagement. The protocol has proven feasible, beneficial, and is easily adaptable to other high-stress workplaces.

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

This manuscript describes how to use the wavelet entropy index to analyze high-density electroencephalography (EEG) and electrocardiography (ECG) data. We show that the irregularity of cerebral and cardiac activities became more coordinated during mindfulness-based stress reduction practice.

Ammonia is an important physiologic metabolite relevant to various disease and wellness states. It is also a difficult molecule to measure in breath, which demands particular precautions be taken to obtain accurate results. Not all factors influencing ammonia are known, but progress can be difficult without accounting for these factors.

Understanding how consumers feel and think about a brand is essential for its success. Emotional responses, like the connection a customer feels to a favorite clothing brand, can drive loyalty and long-term engagement. On the other hand, cognitive responses, such as recognizing the specific benefits of a particular insurance policy, help reinforce trust and informed decision-making. For example, awareness measures how many people recognize a brand, such as a new snack brand gaining popularity...
FAQs
During inhalation, contraction of the diaphragm enlarges the thoracic cavity and lowers lung pressure, drawing air inward. When the diaphragm relaxes, the pressure gradient reverses and air movement changes direction. Mindful observation of these phases lets students connect a breathing cycle with pressure differentials and volume changes in a moving gas.
The diaphragm links muscular motion to changing volume in the chest. Its contraction enlarges the thoracic cavity, whereas relaxation reverses that change. Because this movement repeats, breathing offers a clear example of cyclic motion: a physical system passes through recurring phases rather than remaining at one fixed pressure or volume.
After air reaches the alveoli, oxygen and carbon dioxide move across alveolar membranes by diffusion. This stage adds a microscopic transport process to the larger-scale movement of air through the lungs. In physics education, it helps distinguish air movement through the respiratory system from gas transfer across a thin biological boundary.
Mindful Breathing makes rhythm and depth useful observational variables. Rhythm highlights the repeated timing of the cycle, while depth draws attention to how pronounced each breath feels alongside changes in cavity volume. Considering these features together helps learners connect direct sensory observation with the pressure, volume, and airflow concepts used to describe the process.
A basic exercise can begin by deliberately attending to breathing sensations, rhythm, and depth. During each cycle, the learner can relate the inward phase to diaphragm contraction, thoracic expansion, lower lung pressure, and incoming air, then relate the outward phase to relaxation and reversal. Repeated cycles provide a structured sequence for sustained observation.
Mindful Breathing brings together fluid flow as air moves, pressure differentials that drive movement, gas exchange across alveolar membranes, and cyclic motion produced by repeated breathing phases. Presenting these ideas together helps learners see how several physical processes operate within one familiar biological system rather than studying each concept in isolation.
In physics learning and experimental work, structured attention can support calm, sustained observation. That can help a learner track repeated phases, compare breathing features, and follow how pressure, volume, and gas movement relate over time. The practice therefore offers an attentional framework for examining a physical process with greater continuity during study or investigation.
