Anxiety and mood
Why do I keep replaying conversations in my head?
The joke at work drinks, the text you sent too fast. People made to wear an embarrassing T-shirt guessed half the room had noticed. Far fewer had.
Tool, 5 minutes
Worry time means giving your worries one fixed 15 minutes a day. When one shows up earlier, you write it down and save it for then. In small studies, people who did this for two weeks worried less. Type your first worry below.

Start with whichever worry is loudest right now.
Follow the dot along the line. Breathe in while it climbs and out while it sinks. There’s no sound.
Press start when you’re ready.
Worry time is a fixed 15 minutes each day that belongs to your worries. When a worry turns up at another moment, you write it down in a few words and leave it for later. When the time comes, you sit down with the list and think each one through properly. By then some will have shrunk, and you can act on a few of the others. The rest waits for tomorrow.
The idea goes back to a 1983 study with students who worried a lot. The ones who saved their worries for one set half hour a day said they spent less of their day worrying.1
A little, in small studies. After two weeks of half an hour a day in the same place, 53 people who worried a lot were worrying less, feeling less tense and sleeping somewhat better than a group who were only told not to push their worries away.2 Their low moods, though, lifted no more than the other group’s.
Most worry time studies are small and short, and the people in them knew what they were trying. A larger trial gave 136 stressed workers a phone app that taught putting worries off, along with mindfulness exercises. After four weeks it made no measurable difference to their stress or their heart rhythm.3 So try it for a couple of weeks and see. The studies don’t promise more than that.
Worry spreads. If you worry on the bus, at your desk and in bed, each of those places starts to bring the worry back by itself. Giving it one time and one chair shrinks the number of places that can set it off.2
There’s a second reason. A lot of worries are about things that never happen. Lucas LaFreniere and Michelle Newman had 29 heavy worriers write their worries down for ten days and then check what came of them. About 9 in 10 of those worries didn’t come true.4 Waiting a few hours gives you a chance to notice that for yourself.
The last minute of worry time is for slow breathing, mostly so the list has a clear end. Breathing slowly, under about 10 breaths a minute, tends to leave people calmer and more relaxed when it is tested in a lab.5 A month-long trial put it next to meditation: five minutes a day of breathing with long breaths out lifted people’s mood more than the same time spent on mindfulness meditation.6
The 4, 7, 8 count is a popular version with a long hold in the middle. The studies here tested slow breathing in general, not that exact count, so pick whichever feels easier. If holding your breath makes you light-headed, stay with the first one.
