Here on the web you haven’t answered the health check, so holds stay at 3 seconds: the same limit the app keeps when someone picks “Prefer not to say”.

Evidence
Real evidence. Honest about the gaps.
Every technique carries a grade for how well it is studied, and every benefit line links to its studies. Where research is still early, Oxigen says so.
At least one randomized trial of this technique with mostly positive results, or a close member of a well-studied family.
Small, uncontrolled or non-randomized studies, or mixed results.
Traditional practice or physiological rationale only, not yet studied on its own.
Breathing around six breaths a minute is one of the best-studied ways to raise heart-rate variability, a marker of relaxation.
In a 4-week study, 5 minutes a day of cyclic sighing improved positive mood more than mindfulness meditation.
Oxigen never says treat, cure or clinically proven. Grades describe evidence for feeling calmer, more alert or more focused, never a claim about treating a condition.
Safety
Safe by design.
Breathing exercises are powerful, and some aren’t right for everyone. Oxigen checks at every step.
A short health check
It hides techniques that aren’t right for you and keeps breath holds short. “Prefer not to say” applies the strictest filter.
A readiness check for intense breathing
Intense techniques need a readiness check first, and your first run is shorter.
“I feel unwell” in every session
One tap stops the session and shows what to do next. Intense techniques pause for a week after a dizzy spell.
The gentlest setting first
Everything starts at the gentlest setting; you choose when to go further.
Before an intense session
- I’m sitting or lying down
- I’m not in or near water and not driving
- I’ll stop if I feel unwell
In every session
I feel unwellIf you feel dizzy, faint or unwell, tap I feel unwell and breathe normally.

What is box breathing?
Box breathing is a rhythm with four equal sides: breathe in, hold, breathe out, hold, usually 4 seconds each. It’s popular with people who perform under pressure and gives you a steady rhythm to focus on. Early studies suggest it may help steady your body’s response to stress. More about Box Breathing.
What is coherent breathing?
Coherent breathing is smooth, even breathing at about six breaths a minute: roughly 5 seconds in and 5 seconds out, with no pauses. Breathing around six breaths a minute is one of the best-studied ways to raise heart-rate variability, a marker of relaxation. More about Coherent Breathing.
Which breathing exercises help you wind down for sleep?
Oxigen’s sleep plans start with Extended Exhale, including slower 4-8 and 7-11 rhythms, and 4-7-8 breathing, with Humming Breath, Coherent Breathing and Left-Nostril Breathing as alternatives. Longer out-breaths are a simple way to slow down. 4-7-8 is a bedtime favorite; research on 4-7-8 itself is still early. More about 4-7-8 Breathing.
What does an evidence grade mean?
Every technique in Oxigen shows how well it is studied. A means meta-analyses of randomized trials support it (Well studied), B means at least one randomized trial (Studied), C means small or early studies (Early research) and T means traditional practice only (Traditional). Grades describe evidence for feeling calmer, more alert or more focused, never for treating a condition.
Is Oxigen a medical app?
No. Oxigen is a wellness app, not a medical device. It does not diagnose, treat, cure, or prevent any medical condition. If you have a health condition or are pregnant, talk to your doctor before starting, and keep following your care plan.
How does Oxigen keep breathing practice safe?
A short health check hides techniques that aren’t right for you and keeps breath holds short. Intense techniques need a readiness check first, and your first run is shorter. “I feel unwell” is in every session: one tap stops it and shows what to do next. Everything starts at the gentlest setting, and you choose when to go further.
Does Oxigen collect my health data?

Oxigen collects anonymous usage analytics, which you can turn off any time in You → Help improve Oxigen, and crash reports. You can export or delete everything in the app at any time.
