Calm, Focus & Sleep

Simple breathing techniques you can practice right now, all built into Dandelion Reflect with animated visual guides that breathe with you.

4-7-8 Breathing

A long-exhale pattern for winding down

Inhale 4s → Hold 7s → Exhale 8s

Developed by Dr. Andrew Weil, the 4-7-8 technique is based on pranayama, an ancient yogic practice. Slow breathing with a long exhale is linked to lower arousal. Many people find the long exhale calming, and it's a popular part of a bedtime routine.

How to practice

  1. 1Sit or lie in a comfortable position
  2. 2Breathe in quietly through your nose for 4 seconds
  3. 3Hold your breath for 7 seconds
  4. 4Exhale completely through your mouth for 8 seconds, making a gentle whoosh sound
  5. 5Repeat for 2 to 4 cycles. Start with 2 if you're new.

Best for

  • Winding down before bed
  • Deep relaxation
  • Unwinding in the evening

Box Breathing

A steady count for pressured moments

Inhale 4s → Hold 4s → Exhale 4s → Hold 4s

Box breathing (also called square breathing or four-square breathing) is widely associated with U.S. Navy SEAL training, popularized by former SEAL Mark Divine. Its equal four-phase rhythm gives you a predictable pattern to follow when you're under pressure. Each phase is the same length, so it's easy to remember even when stressed.

How to practice

  1. 1Sit upright with your feet flat on the floor
  2. 2Breathe in through your nose for 4 seconds
  3. 3Hold your breath for 4 seconds — don't clamp down, just pause
  4. 4Exhale slowly through your mouth for 4 seconds
  5. 5Hold with empty lungs for 4 seconds
  6. 6Repeat for 4-6 cycles

Best for

  • High-pressure situations
  • Before meetings or exams
  • Sharpening focus

Calm Breathing

A simple long-exhale rhythm

Inhale 4s → Exhale 6s

Calm breathing works on one simple idea: when your exhale is longer than your inhale, many people find their breathing and body settle. There are no holds and no complex counts, just a gentle rhythm.

How to practice

  1. 1Find a comfortable position — sitting, lying down, or even standing
  2. 2Breathe in through your nose for 4 seconds
  3. 3Breathe out slowly through your mouth for 6 seconds
  4. 4Focus on making the exhale smooth and steady
  5. 5Continue for 2-5 minutes

Best for

  • Everyday calm
  • Gentle wind-down
  • Beginners

Energizing Breath

A quick pick-me-up

Inhale 2s → Exhale 2s

Quick, equal breaths can feel refreshing when you're sluggish. Keep it short (10-15 cycles), and stop if you feel light-headed or tingly.

How to practice

  1. 1Sit up straight to open your airways
  2. 2Breathe in through your nose for 2 seconds
  3. 3Breathe out through your mouth for 2 seconds
  4. 4Keep the rhythm quick and steady
  5. 5Do 10-15 cycles, then return to normal breathing. Stop if you feel light-headed or tingly.

Best for

  • Afternoon energy dip
  • Before exercise
  • Waking up alert

Physiological Sigh (Double Breath)

A quick double-inhale pause

Inhale 2s → Top-up inhale 1s → Exhale 6s

Popularized by Stanford neuroscientist Andrew Huberman, the physiological sigh is a double inhale through the nose followed by a long exhale. People sigh like this on their own, often when stressed or drifting off to sleep. Practiced for 5 minutes a day as cyclic sighing, it was the technique that lifted mood most in a small 2023 Stanford study.

How to practice

  1. 1Take a quick inhale through your nose (2 seconds)
  2. 2Without exhaling, take a second, shorter inhale through your nose to top up your lungs (1 second)
  3. 3Exhale slowly and completely through your mouth (6 seconds)
  4. 4One or two cycles make a quick pause. The 2023 study used 5 minutes a day.

Best for

  • A quick pause
  • Before a hard conversation
  • Emotional reset

Coherent Breathing

Slow, even breathing

Inhale 5s → Exhale 5s

Coherent (resonant) breathing is slow, even breathing at roughly 5-6 breaths a minute, the range where heart rate variability (HRV) tends to be highest. The exact pace differs from person to person; our timer uses 5 seconds in, 5 seconds out. High HRV is associated with better emotional regulation, lower stress, and improved cardiovascular health. This technique is used in biofeedback therapy and suits a daily practice during meditation.

How to practice

  1. 1Sit comfortably with your eyes closed
  2. 2Breathe in slowly through your nose for 5 seconds
  3. 3Breathe out slowly through your nose for 5 seconds
  4. 4Keep the transition between inhale and exhale smooth — no pausing
  5. 5Practice for 5-20 minutes

Best for

  • Meditation
  • Emotional regulation
  • Heart rate variability training

2-1-4-1 Relaxing Breath

Gently force a racing mind to slow down

Inhale 2s → Hold 1s → Exhale 4s → Hold 1s

When your mind is running faster than you'd like, this technique uses rhythm to gently override the mental chatter. The short inhale prevents hyperventilation, the micro-holds create natural pause points, and the extended exhale activates your relaxation response. The rhythm is easy enough to follow even when distracted, which makes it particularly effective for anxiety.

How to practice

  1. 1Breathe in through your nose for 2 seconds
  2. 2Pause gently for 1 second
  3. 3Exhale through your mouth for 4 seconds
  4. 4Pause gently for 1 second
  5. 5Repeat for 2-4 minutes

Best for

  • Racing thoughts
  • Mild anxiety
  • Transitioning between tasks

Deep Calm (4-2-6)

A gentler gateway to deep breathing

Inhale 4s → Hold 2s → Exhale 6s

If the 4-7-8 technique feels too demanding (that 7-second hold can be uncomfortable for beginners), Deep Calm offers the same extended-exhale benefit with a much shorter hold. It's the ideal starting point for anyone new to breathwork. The 4-2-6 pattern is comfortable enough to sustain for longer sessions while still producing meaningful relaxation.

How to practice

  1. 1Sit or lie comfortably
  2. 2Inhale through your nose for 4 seconds
  3. 3Hold gently for 2 seconds
  4. 4Exhale slowly through your mouth for 6 seconds
  5. 5Continue for 3-10 minutes

Best for

  • Beginners
  • Gentle relaxation
  • People who find 4-7-8 too intense

Nadi Shodhana (Alternate Nostril)

A traditional yogic practice for settling the mind

Left in 4s → Hold 2s → Right out 4s, then reverse

Nadi Shodhana is a traditional pranayama practice ('nadi' means channel, 'shodhana' means cleansing). Many people use it to settle before meditation or focused work.

How to practice

  1. 1Sit comfortably with your spine straight
  2. 2Close your right nostril with your right thumb and breathe in through your left nostril for 4 seconds
  3. 3Close your left nostril with your ring finger too, and hold for 2 seconds
  4. 4Release your right nostril and breathe out through it for 4 seconds
  5. 5Breathe in through the right nostril for 4 seconds, hold for 2, then breathe out through the left. That's one round.

Best for

  • Mental clarity
  • Before creative work
  • Balancing energy

3-3-3 Grounding

Predictable simplicity when everything feels chaotic

Inhale 3s → Hold 3s → Exhale 3s

When you feel overwhelmed, a complicated technique is hard to follow. The 3-3-3 grounding breath is deliberately simple: equal phases, short and easy to remember. The steady count gives your attention one predictable thing to hold. If you have panic attacks, talk to a doctor or therapist; breathing exercises are not a treatment.

How to practice

  1. 1You can do this anywhere — standing, sitting, even walking
  2. 2Breathe in for 3 seconds
  3. 3Hold for 3 seconds
  4. 4Breathe out for 3 seconds
  5. 5Focus only on the counting — let it anchor you
  6. 6Continue for as long as it feels steadying

Best for

  • Feeling overwhelmed
  • A simple rhythm to follow
  • Anywhere, any time

Frequently asked questions

What is the best breathing exercise for anxiety?

There's no single best one. The physiological sigh (a double inhale through the nose, then a long exhale) is quick to try. In a 2023 Stanford study (Balban et al., Cell Reports Medicine), 108 adults did 5 minutes of breathwork or mindfulness meditation a day for 28 days. Breathwork lifted positive mood more than meditation, and cyclic sighing showed the clearest effect on mood and resting breathing rate. Read the study

How does 4-7-8 breathing work?

4-7-8 breathing makes the exhale twice as long as the inhale, and slow, exhale-weighted breathing is linked to lower arousal. Inhale for 4, hold for 7, exhale for 8. Dr. Andrew Weil popularized it from pranayama. Many people find it calming.

What is box breathing, and why is it linked to Navy SEALs?

Box breathing is a four-equal-count technique: inhale 4s, hold 4s, exhale 4s, hold 4s. It's widely associated with Navy SEAL training, where former SEAL Mark Divine popularized it. In a 2023 Cell Reports Medicine randomized trial, five minutes of daily breathwork (box breathing or cyclic sighing among them) for a month improved mood, with cyclic sighing improving it more than mindfulness meditation. Read the study

How long should I practice breathing exercises?

There's no minimum. A few slow cycles are a reasonable place to start; studies of slow breathing usually use sessions of 5 minutes or more. For winding down before sleep, 5-10 minutes of 4-7-8 or coherent breathing is a common choice.

Can I do breathing exercises lying down?

Yes, most exercises work lying down, and many people prefer 4-7-8 or coherent breathing in bed. Box breathing is usually done sitting up.

What is the difference between 4-7-8 breathing and box breathing?

4-7-8 has a long hold and a long exhale and is aimed at winding down, so many people use it before sleep. Box breathing uses four equal phases, which gives you a steady rhythm while keeping you alert, so people often reach for it before a meeting or an exam.

What is coherent breathing and how does it help?

Coherent (resonant) breathing is slow, even breathing at roughly 5-6 breaths a minute, the range where heart rate variability (HRV) tends to be highest. The exact pace differs from person to person; our timer uses 5 seconds in, 5 seconds out. It's used in biofeedback, and people usually practice it for 10-20 minutes at a time.

Is box breathing safe for people with respiratory conditions?

Box breathing is safe for most healthy adults, but people with COPD, asthma, or other respiratory conditions should consult a doctor before attempting breath holds. If you feel lightheaded during any breathing exercise, return to normal breathing immediately.

Can children practice breathing exercises?

Yes, with simpler timing. Shorter, simpler patterns suit children better, such as the 3-3-3 grounding breath or calm breathing (4 seconds in, 6 seconds out). Avoid long breath holds for younger children.
