What Ten Minutes of Writing Does to Your Evening

I want to be careful here, because there is a whole shelf of books willing to promise you that a bedtime routine will fix your sleep. I am not going to. I know nothing about your sleep, and if you are lying awake most nights that is a conversation for a doctor, not for a notebook.

What I can tell you is what changed in my evenings when I started writing for ten minutes before bed, and why I think it changed.

The list never stops. It just stops being written down anywhere

Between about ten and eleven at night most of us run a quiet inventory. The message you did not reply to. The appointment you have not made. The sentence somebody said at four o'clock that you have now replayed nine times.

None of it is urgent. All of it is being held. Holding something is work, and it is work you do not notice doing, because there is nothing to see. You are lying still in the dark. It looks exactly like resting.

Paper is somewhere to put things down

Writing the inventory out takes about four minutes. Not solving it, not planning it. Just putting it in a line: ring the dentist, Sam's thing on Thursday, reply to Priya.

Once it is on the page your head stops rehearsing it. Rehearsal is what it does to make sure you do not forget, and the page has now taken that job. There is nothing mystical about it. You moved a list from somewhere that keeps reminding you to somewhere that will still have it in the morning.

The second half is the part people skip

Four minutes of list, then six minutes of one honest sentence about the day. Not a summary. One thing that happened and how it landed. "The meeting went fine and I still felt sick before it." "Mum was cheerful, which was somehow worse."

On their own those sentences are nothing. Ninety of them in a row and you can see quite plainly which situations cost you and which ones you only expected to.

One honest sentence is nothing. Ninety of them in a row is evidence.

Why handwriting and not a note on your phone

I have no argument against typing except a practical one. The phone is where a good deal of the inventory came from, and opening it at eleven at night to write two sentences is an invitation you do not need.

There is also the speed. Handwriting is slow enough that you finish the thought before you finish the sentence, and slow enough that you only put down the parts that matter. A keyboard will happily let you produce four hundred words of the same worry.

What actually changes

• The evening ends. Closing a book is a clearer signal than switching off a lamp.
• You stop arguing with yourself about whether it was a bad week. You look it up.
• The same three or four triggers keep appearing, and after a month you notice you have quietly rearranged your week around two of them without ever making a decision about it.

How to keep it small enough to survive a Tuesday

• Keep it under ten minutes. Set no timer, but stop at the point where you would rather be reading.
• Do not write it on your phone. The phone is where most of the list came from.
• Same place every night. The edge of the bed is a fine desk.
• On an empty night, write the date and one word. The date is the record. The word is a bonus.

A book for the second half

The Stress Log is ninety days of exactly this. A short entry for the day, a scale for how the evening felt and room for what set you off. Ninety days is long enough to argue with.

It will not tell you what is coming. It tells you what has been happening, which is the part most of us turn out to be surprisingly vague about.

And if the writing helps and the sleep does not, that is worth knowing too. Take the ninety pages with you when you go and see somebody. Dates written down at the time are worth a great deal more than a memory of a bad month.
