Aeolian

Much of it is genuinely studied. Slowing to about six breaths a minute has solid support for raising heart-rate variability and easing stress (Zaccaro 2018; Lehrer & Gevirtz 2014), and a Stanford randomized trial found five minutes a day of cyclic sighing lifted mood more than mindfulness (Balban 2023). Other techniques are more preliminary, and each technique's Evidence section says so honestly, with a strength rating that reflects the current weight of research. It isn't a cure; it's a way to nudge your nervous system, grounded in physiology.

There's overlap, but the lever is different. This is about the mechanics of breathing, using pace and depth to steer yourself between calm and alert, rather than watching your thoughts. You don't have to empty your mind or sit still for twenty minutes. If meditation never quite clicked for you, paced breathing is a more physical, concrete place to start.

No. The app deliberately speaks in physiology, vagus nerve, heart rate, CO₂ , and skips the mystical framing. That said, many of these practices come from long contemplative traditions, and if that lineage means something to you, it's here to respect, not to wave away. Take the mechanism and leave the metaphysics, or keep both, the breathing works the same either way.

Feel it first: a few long, slow exhales usually drop your heart rate within a breath or two. If you want something more objective, the Pulse & HRV tool (experimental) lets you take a quick camera reading before and after a session and watch the number change for yourself, about as close to proof as a phone can offer.

Two easy on-ramps: the Physiological Sigh (the fastest way to take the edge off in the moment) and Resonance Breathing (the daily driver, slow, even breaths at about six a minute). Or just tap the tree on Home for two quiet minutes, or pick a direction, Calm, Sleep, Focus, or Energy, and let the app suggest one.

A little every day beats a lot once in a while. Even five minutes a day of slow breathing can shift how you feel, and the daily-habit techniques reward consistency, HRV benefits tend to build over weeks. Use the quick tools whenever you need them; if you like structure, a Journey sets a daily rhythm.

For most people, the gentle slow-breathing techniques are very low-risk. The fast, intense methods, Bhastrika, Power Breathing, Conscious Connected, carry real risks, fainting above all: never do them in or near water, while driving, or standing unsupported. Read a technique's cautions before you start, and see Safety & Contraindications above. This is a wellness and education tool, not medical care.

With faster or deeper breathing, tingling and light dizziness are common, usually just CO₂ dropping, not danger, and they pass when you return to normal breathing. Treat them as your signal to ease off. If you ever feel faint, stop, sit or lie down, and breathe normally. Severe or lasting symptoms should be treated as a medical issue.

Yes. Some techniques aren't appropriate with high blood pressure, heart conditions, glaucoma, epilepsy, pregnancy, or serious mental-health conditions, among others. Each higher-risk technique lists its contraindications, and the Safety section covers it in full. When in doubt, especially with the intense methods, check with a qualified professional before starting.

No. It can be a helpful companion to real care, for stress, sleep, and steadiness, but it isn't a substitute for professional treatment, and it won't resolve a medical or mental-health condition on its own. If you're struggling, please reach out to a qualified professional.

For the calming techniques, nose breathing is usually best, it slows and warms the air. The counts are guides, not tests: if a hold feels strained, shorten it. The pacer does the counting, so your only job is to follow the orb.

Yes to both. Aeolian runs entirely on your device, no account, no servers. Your settings and any readings stay on your phone, and it works with no signal at all: on a plane, in the mountains, anywhere.
