How Breathing Exercises Can Help Dementia Caregivers Regulate Stress
How breathing affects stress
The caregiver’s nervous system is part of the caregiving environment
What kind of breathing are we talking about?
Nose or mouth: how should you exhale?
Box breathing: 4-4-4-4
Hold for 4 seconds.
Exhale gently through the nose for 4 seconds.
Hold again for 4 seconds.
Repeat for 1 to 5 minutes.
4-7-8 breathing
Hold for 7 seconds.
Exhale slowly through the mouth for 8 seconds.
Repeat for 4 cycles to start.
4-6 breathing
Exhale gently through the nose for 6 seconds.
Repeat for 3 to 5 minutes.
Coherent breathing
Exhale through the nose for 5 seconds.
Continue for 5 minutes.
The physiological sigh, or cyclic sighing
Before exhaling, take a second small inhale through the nose.
Then exhale slowly and completely through the mouth.
Repeat 3 to 5 times.
The spiritual dimension of breath
“May I be patient.”
“May I not abandon myself.”
“One breath at a time.”
The psychological benefit: the pause
A parent accuses you of stealing.
A spouse asks to go home while already sitting in the home they have lived in for forty years.
A sibling criticizes from a distance but does not help.
The physiological benefit: reducing wear and tear
When to use breathing during caregiving
Before helping with bathing or toileting.
Before responding to agitation.
After a medical appointment.
After a frightening episode.
Before calling family members.
While waiting in the car.
Before sleep.
When resentment or guilt spikes.
When you notice your shoulders rising, jaw tightening, or breath becoming shallow.
A simple seven-day caregiver breathing plan
Day 2: Try box breathing for one minute.
Day 3: Use the physiological sigh three times during the day.
Day 4: Practice 4-7-8 breathing before bed.
Day 5: Use 4-6 breathing before a known stress point.
Day 6: Try coherent breathing for five minutes.
Day 7: Choose the one technique that felt most natural and repeat it.
Safety notes
The deeper truth
They can interrupt panic.
They can soften anger before it becomes injury.
They can make space for prayer.
They can help a person sleep.
They can provide a moment of dignity when the day has offered very little.
Glossary
A breathing pattern that involves inhaling for 4 seconds, holding for 7 seconds, and exhaling for 8 seconds. It is often used for relaxation or sleep.
A form of grief that occurs when someone is physically present but psychologically or emotionally changed. Dementia caregivers often experience this as they mourn the gradual loss of the person they once knew while still caring for the person in front of them.
The part of the nervous system that manages automatic body functions, including heart rate, blood pressure, breathing rhythm, digestion, sweating, and pupil size. It operates mostly outside conscious control.
A structured breathing technique using four equal parts: inhale, hold, exhale, hold. A common version is 4-4-4-4.
A state of emotional, physical, and mental exhaustion caused by prolonged caregiving stress. It may include irritability, numbness, guilt, sleep problems, resentment, sadness, and loss of personal identity.
A slow, steady breathing rhythm, often around five to six breaths per minute. A common version is to inhale for 5 seconds and exhale for 5 seconds.
A breathing technique involving a deep inhale, a second small inhale, and a long, slow exhale. It emphasizes the exhale and may help reduce physiological arousal.
A practical term meaning the body is shifting from high alert toward a calmer state. Breathing exercises are often described as downregulating because they may reduce physiological arousal.
An exhale that lasts longer than the inhale. Many calming breathing techniques use an extended exhale because it may help shift the body away from a state of high alert and toward recovery.
The body’s stress response to threat or pressure. It can be lifesaving in danger, but when activated chronically, as often happens in long-term caregiving, it may contribute to exhaustion, irritability, poor sleep, and physical strain.
The natural variation in time between heartbeats. Greater HRV is often interpreted as a sign that the body can flexibly shift between stress and recovery states. Slow breathing can temporarily increase HRV in many people.
The ability to notice internal body signals, such as heartbeat, breathing, hunger, muscle tension, or tightness in the chest. Breathing practices can improve awareness of these signals.
Breathing out through the mouth. A slow, deep exhale can create a stronger sense of release and is often used in sighing, 4-7-8 breathing, and other relaxation practices.
Breathing in or out through the nose. Nasal breathing naturally slows airflow and is often preferred for calming, steady breathing practices.
A gas produced naturally in the body, including in the paranasal sinuses. In the blood vessels, nitric oxide promotes vasodilation, or the relaxation and widening of blood vessels. During nasal breathing, small amounts of nitric oxide from the nose and sinuses mix with inhaled air and may support airway function, oxygen uptake, and blood-flow regulation.
The branch of the autonomic nervous system associated with recovery, digestion, and restoration. It helps slow the heart rate, support digestion, and help the body return to balance after stress. It is often called the “rest-and-digest” system.
A natural breathing pattern involving two inhales followed by a long exhale. It can be used deliberately as a quick calming technique.
The branch of the autonomic nervous system associated with action, alertness, and threat response. It helps prepare the body for stress by increasing heart rate, raising blood pressure, and mobilizing energy. It is often called the “fight-or-flight” system.
A term used to describe how effectively the vagus nerve helps regulate the body, especially heart rate and stress recovery. Higher vagal tone is often associated with better flexibility in responding to stress, though it is not a simple “good or bad” measurement.
A major nerve that connects the brain with the heart, lungs, digestive tract, and other organs. It plays an important role in parasympathetic regulation.
The widening or relaxation of blood vessels. Vasodilation can improve blood flow and may help reduce pressure within blood vessels. Nitric oxide is one of the body’s important signaling molecules for vasodilation.

Simple Breathing Techniques for Stress and Anxiety Relief
Dr. Cho introduces two breathing practices intended to help reduce stress and anxiety: box breathing and a combined abdominal breathing/pursed-lip exhale technique. The video explains each method step by step, including how long to inhale, hold, and exhale, while emphasizing that viewers should stop or reduce the timing if they feel short of breath, dizzy, or uncomfortable.
The central message is that controlled breathing can be used in everyday stressful situations, such as waiting for a medical appointment or calming down during anxiety. The video’s significance lies in its practical, low-barrier approach: it presents short exercises that can be practiced almost anywhere, while reminding viewers to adjust the pace to their comfort level.

Highlights:
- (00:00) — Dr. Cho introduces the video’s goal: teaching two simple breathing techniques to relieve stress.
- (00:41) — The first method is introduced as box breathing, also called square breathing.
- (01:09) — Box breathing is explained as inhaling for 4 seconds, holding for 4 seconds, exhaling for 4 seconds, and holding again for 4 seconds.
- (01:38) — Dr. Cho recommends doing 4 to 5 sets at a time while using a visual image, such as a square, to support relaxation.
- (02:40) — The video notes that holding the breath after exhaling may feel difficult at first but can become easier with practice.
- (03:07) — The second method begins with pursed-lip exhaling, which is described as helping the lungs move more actively.
- (03:32) — Abdominal, or diaphragmatic, breathing is introduced as breathing with the stomach rather than the chest.
- (03:54) — The technique is demonstrated as breathing into the belly for 4 seconds, then pursing the lips and exhaling for 8 seconds.
- (04:52) — Viewers are encouraged to shorten the exhale to 6 or 7 seconds if 8 seconds feels too difficult.
- (05:20) — Dr. Cho cautions viewers not to overdo the techniques if they feel dizzy or faint.
