Glossary
- 4-7-8 Breathing Method
- A breathing technique advocated by Dr. Andrew Weil. Inhale through the nose for 4 seconds, hold your breath for 7 seconds, and exhale slowly through the mouth for 8 seconds. Making the exhalation twice as long as the inhalation activates the parasympathetic nervous system, lowering heart rate and blood pressure. It is highly effective for pre-sleep relaxation and is also known as a 'natural tranquilizer'.
- Box Breathing
- A breathing technique that repeats 4 equal phases of inhaling, holding, exhaling, and holding (usually 4 seconds each). The name comes from visualizing each phase as a side of a square (box). Used in stress management training by Navy SEALs, it is known as a technique for maintaining calmness under extreme tension. Particularly effective for restoring focus and self-control during panic.
- Diaphragmatic Breathing (Belly Breathing)
- A method of breathing deeply by consciously using the diaphragm rather than the chest. It is characterized by the abdomen expanding during inhalation and contracting during exhalation. Compared to chest breathing, it has a larger ventilation volume per breath, increasing oxygen supply efficiency. It is a fundamental technique in yoga, Pilates, and vocal training, and is said to be effective in balancing the autonomic nervous system and lowering stress hormones (cortisol).
- Relaxation Breathing
- A pattern of inhaling for 5 seconds, holding for 2 seconds, and exhaling for 7 seconds. Prolonging the exhalation stimulates the vagus nerve, promoting physical and mental relaxation. It is a milder variation suitable for beginners who find the breath-holding time of 4-7-8 breathing too long. Ideal for daytime refreshment and mild anxiety relief.
- Cycle
- The entire sequence of inhalation → hold → exhalation → hold is counted as one cycle. Many breathing techniques are practiced in sets of 3 to 8 cycles. Beginners are recommended to start with 3 to 4 cycles and gradually increase as they get used to it. The more cycles, the higher the relaxation effect, but if you feel dizzy, stop immediately.
- Phase
- Refers to each stage within a cycle. This tool consists of up to 4 phases: 'Inhale', 'Hold In', 'Exhale', and 'Hold Out'. Some breathing techniques omit the holding phases, and setting the seconds to 0 will automatically skip that phase.
- Autonomic Nervous System
- The nervous system that automatically controls heartbeats, digestion, body temperature regulation, etc., without conscious effort. It consists of two systems: the 'sympathetic nervous system (fight or flight response)' and the 'parasympathetic nervous system (rest and recover response)'. Breathing is one of the few means by which the autonomic nervous system can be consciously regulated, which is the scientific basis for breathing techniques being effective for physical and mental health.
- Parasympathetic Nervous System (Vagus Nerve)
- One of the autonomic nerves, it is the nervous system that promotes relaxation, rest, and digestion. It is activated by deep, slow breathing, especially long exhalations. When the parasympathetic nervous system becomes dominant, heart rate drops, blood pressure falls, and muscle tension eases. The vagus nerve is the longest cranial nerve extending from the brainstem to the abdomen, acting as the 'body's brake'.
- Sympathetic Nervous System
- The autonomic nerve that becomes dominant during stress or tension, raising heart rate, blood pressure, and muscle tension to create a 'fight or flight' state. In modern society, the sympathetic nervous system is prone to being overly dominant continuously, which can cause chronic stress, insomnia, and reduced immunity. It is important to calm this overactivity with conscious breathing techniques and restore balance with the parasympathetic nervous system.
- Breathing Ratio (Inhale-to-Exhale Ratio)
- The ratio of inhalation time to exhalation time. For relaxation purposes, it is considered effective to make exhalation 1.5 to 2 times longer than inhalation (e.g., in 4-7-8 breathing, inhalation is 4 seconds and exhalation is 8 seconds, making it 1:2). Conversely, box breathing, which has the same ratio for inhalation and exhalation, is suited for maintaining focus and alertness rather than relaxation. Selecting the ratio according to your goal is key to maximizing the effectiveness of the breathing technique.

FAQ
- Q.Which breathing method is recommended for beginners?
- We recommend starting with '4-7-8 breathing'. With a simple rhythm of inhaling (4s) → holding (7s) → exhaling (8s), you can start immediately without special techniques. Many report smoother sleep onset just by doing 3-4 cycles before bed. If holding for 7 seconds feels difficult, starting with 'Relaxation breathing' (5-2-7) is a comfortable alternative.
- Q.What are the effects of the 4-7-8 breathing method?
- Making exhalation twice as long as inhalation promotes parasympathetic dominance, lowering heart rate, stabilizing blood pressure, and relaxing muscles. Dr. Andrew Weil suggests continuous practice reduces anxiety and stress, improves sleep, and helps control anger. Its immediate effect makes it useful for quick relaxation in tense situations.
- Q.How is box breathing different from 4-7-8 breathing?
- Box breathing balances 4 equal phases (4-4-4-4s) and focuses on maintaining/restoring concentration rather than relaxation, used even in Navy SEALs training. Conversely, 4-7-8 breathing is designed to induce deep relaxation with longer exhalations. It's effective to use box breathing for 'focus resets at work' and 4-7-8 for 'pre-sleep relaxation'.
- Q.How many cycles are appropriate?
- Beginners should start with 3-4 cycles. Once accustomed, increasing to 5-8 cycles enhances effects. A session takes about 2-5 mins for 4-7-8 and 1-3 mins for box breathing. If you feel dizzy or breathless, stop immediately and return to normal breathing. Forcing more cycles is not recommended.
- Q.Can I create my own breathing pattern?
- Yes. In the 'Custom Settings' area, you can freely set each phase (inhale, hold, exhale, hold) between 0 and 30 seconds. Setting a phase to 0 seconds automatically skips it. For instance, '3-0-6-0' creates a simple belly breathing pattern without holds. Customize to fit your physical condition and goals.
- Q.Can I mute the guide sounds to use it quietly?
- Turning OFF the 'Sound' checkbox in the control bar mutes all phase transition sounds and completion chimes. It switches to a 'Visual Only' mode that guides breathing via animation and countdowns, allowing you to use it in quiet environments like between meetings or in the office.
- Q.Can I use it on a smartphone?
- Yes. It's responsive and works comfortably on both iOS (Safari) and Android (Chrome). All animation, sound, and timer features run on mobile browsers. However, since the timer might pause if the screen locks (sleeps), please extend your auto-lock time or keep the screen active during sessions.
- Q.Can I pause or stop during a session?
- Yes. You can pause anytime during a session with the 'Pause' button and restart from the same phase with the 'Resume' button. The 'Stop' button resets the entire session so you can start over. If you feel unwell, do not overdo it and stop immediately.
- Q.Is any data sent to the server?
- Not at all. This tool executes all processes (timer control, animation, audio generation) locally within your browser via JavaScript. No server communication occurs, and personal data like usage history or breathing patterns are never collected, saved, or transmitted. It functions even without an internet connection once loaded.
- Q.Are there any precautions for practicing breathing methods?
- While generally safe, there are some precautions. Stop immediately and resume normal breathing if you feel dizzy or numbness. Those with respiratory issues like asthma, pregnant women, and people with low blood pressure should consult a doctor before practicing. Avoid using it while driving, underwater, or in situations where altered consciousness could be dangerous.
