The three-minute breathing space comes from mindfulness-based cognitive therapy, the eight-week course that Zindel Segal, Mark Williams and John Teasdale set out in Mindfulness-Based Cognitive Therapy for Depression. This hourglass is an independent practice page. Its authors, their publisher and the people who train MBCT teachers had no hand in it and have not endorsed it.

The breathing space exists because a long meditation is hard to reach for in the middle of a bad afternoon. Segal has explained that he, Teasdale and Williams designed it for real-world moments, whenever automatic pilot takes over, and that each of its three steps lasts roughly a minute. It is short enough to fit between two meetings and shaped enough that you know what to do once you are in it.

Wide, narrow, wide

Williams and his coauthor Danny Penman suggest you picture the practice as an hourglass, and the shape carries the whole instruction.

• Becoming aware is the wide top of the glass. You sit or stand a little taller and ask what is here right now: which thoughts, which feelings, which sensations. Nothing needs fixing. You are taking stock.
• Gathering is the narrow neck. Attention closes down to one thing, the breath low in the belly as it rises and falls. When the mind wanders, you notice where it went and come back.
• Expanding is the broad base. Awareness opens out around the breath to the body as a whole: posture, face, hands, any place that feels tight.

Nothing in the practice asks you to breathe in a special way. Your breath keeps its own pace; the glass only paces where your attention rests.

How the hourglass on this page works

Before you turn the glass, you mark how settled you feel on a row of five sand marks, from stirred up to settled, and you can tap up to four things that are here, or write your own. Then a light moves through the painted glass. It drains from the top bulb during the first minute, gathers into a bead in the neck during the second and fills the base during the third. The words for each step sit beside it, with a quiet note of how long is left. If you would rather close your eyes, glance back when you like. If you switch tabs or your screen goes dark, the glass keeps time by the clock and picks up wherever it has got to.

Afterward you check in again: how settled you are now, which of the things you named are still here, and which step was hardest to stay with. Keep the space and it lands on a day line at the hour you started it. After a week or so the record begins to answer two practical questions: when in the day you actually reach for a breathing space, and where your attention slips most. When one step keeps slipping, the reading offers a way back into it.

What the evidence says, and what it does not

MBCT has a solid research base. An individual patient data meta-analysis pooled nine randomized trials covering 1,258 people with recurrent depression and found that those who took the course were less likely to relapse over roughly sixty weeks than those who did not. Comparisons with other active treatments, antidepressants among them, also leaned in its favor.

That finding belongs to the whole program, with its weekly classes and practice at home in between. The breathing space by itself has hardly been studied, so nobody can say how much of MBCT's benefit it carries. Treat this page as a practice rather than a treatment. The aim is not to relax on command, either: the steps ask you to notice and allow what is there, so a space that leaves you as stirred up as before still counts.

If low moods keep coming back, a therapist trained in MBCT can take you through the full course, which is where the evidence actually sits. And if dark thoughts turn toward ending your life, set the hourglass aside and call or text 988 in the US, or your local emergency number, so you can talk to someone right away.

When to turn the glass

Williams and Penman describe two uses for it: a regular pause that punctuates the day, and an emergency practice for the moments when you feel under pressure. Try both. Put the first few spaces somewhere easy, such as after lunch or before you open your inbox, so the steps feel familiar. Then reach for the glass in harder moments: before a difficult call, in the parked car, when a worry starts to loop.

If one thought keeps grabbing you in the middle of a space, Thoughts Are Not Facts works on exactly that. For a longer practice, The Body Scan Cord walks attention through the body part by part, and on days when three minutes feels like too much, The Minute Bench asks for only one.
