Extended Exhale
Four in, four held, eight out. Stretching the exhale to twice the inhale rests on one of the most consistently measured effects among breathing techniques.

Four seconds in through the nose. Hold for four. Breathe out slowly through the mouth over eight seconds.
The exhale being longer than the inhale is the whole logic of this technique.
Why a long exhale
Heart rate swings with the breath: it speeds up as you breathe in and slows as you breathe out. In a healthy heart this is expected.
Lengthening the exhale means lengthening the part where the heart slows. In measurements this shows as the average heart rate falling and heart rate variability rising.
It is one of the most consistently demonstrated effects among breathing techniques. The sentence "a long exhale slows the heart" stands on far firmer ground than "a long exhale takes anxiety away".
How to do it
Sit upright. Breathe in through the nose for four seconds — not enough to burst your lungs, just enough to last eight seconds.
Hold for four seconds.
Breathe out through the mouth for eight seconds. As if blowing out a candle, but without blowing: lips slightly parted, the air leaving thin and quiet.
Common mistakes
Finishing the exhale at the fifth second. The most common problem. The cause is usually not taking in too little on the inhale but emptying too fast at the start. Give less in the first second and spread the rest to the end.
Blowing. Forcing the air out speeds the exhale up and takes the effect away. Let the air leave by itself.
Getting stuck on eight seconds. If eight feels long, drop to six. What matters isn't the number but the exhale being clearly longer than the inhale.
How the app measures it
The exhale is through the mouth, so the sound is strong — this is one of the techniques the app measures most comfortably.
What gets measured: how long the exhale lasts, how steady the sound level stays through it, and whether air escaped during the hold.
Exhale length is the component that drops most often in this technique. If that line comes out low in the report, the first place to look is whether the exhale is emptying too fast at the start.
Who should take care
If you feel dizzy during a long exhale, shorten the length. For people who mark a tendency to dizziness, the app steers away from this technique and shows a warning — the technique isn't hidden, but it moves down the order.
