Breathing is not only a basic function but also a tool that may influence stress, focus, and overall health. Simple techniques practiced for just a few minutes can provide relaxation and balance to both body and mind. Among them, the 4-7-8 breathing method and box breathing are often suggested as highly effective. This article outlines these and other quick practices for everyday use.

1. The Principle of Breathing Techniques
Controlled breathing may regulate the autonomic nervous system. Slow, steady patterns may activate the parasympathetic system, helping to reduce tension and promote calmness.
2. 4-7-8 Breathing
Popularized by Dr. Andrew Weil, this method involves inhaling through the nose for 4 seconds, holding for 7 seconds, and exhaling slowly through the mouth for 8 seconds. It may lower heart rate, relieve anxiety, and support better sleep.
3. Box Breathing
Also called square breathing, this practice is used by Navy SEALs for stress control. The cycle includes inhaling for 4 seconds, holding for 4, exhaling for 4, and holding again for 4. This steady rhythm may improve focus and resilience.
4. Diaphragmatic Breathing
Also known as belly breathing, this technique involves expanding the abdomen while inhaling and contracting it while exhaling. It may reduce stress and aid digestion.
5. Alternate Nostril Breathing
A yoga-based practice where one nostril is closed while inhaling and the other while exhaling. It may balance brain activity and support mental clarity.
6. Mindful Breathing
Paying close attention to the inhale and exhale, without judgment, may promote awareness and emotional regulation. Even a few minutes may calm restless thoughts.
7. Practical Applications
These methods can be applied before sleep, during stressful meetings, or while commuting. Just a few minutes may bring noticeable relaxation and focus.

Breathing techniques such as 4-7-8 and box breathing are simple yet powerful tools. Practicing them regularly may improve sleep quality, reduce stress, and enhance concentration. Even short daily sessions may provide meaningful benefits for health and well-being.
