The hardest part of a good evening is not falling asleep. It is stopping. You finish the dishes, you sit down, and somehow it is eleven o'clock and you are still holding your phone with your shoulders up around your ears.

A wind-down routine is not a luxury and it does not need to be elaborate. Twenty minutes, the same twenty minutes, most nights. Here is one that works because it asks very little of you.

Minutes 1 to 3: change the light and the smell of the room

Your brain takes cues from the room long before it takes cues from you. Turn off the overhead light and put on one lamp. Then start a diffuser. Scent is the fastest shortcut there is to a change of state, which is why the smell of a room can settle you before you have consciously decided to settle.

Lavender is the obvious one and it is popular for a reason. Bergamot, cedarwood and chamomile are worth trying if lavender does nothing for you. A quiet essential oil diffuser running in the background does more for an evening than most people expect.

Minutes 4 to 6: put the phone somewhere else

Not face down on the arm of the sofa. In another room, on a charger. This is the single step people skip and the single step that makes the other nineteen minutes work. If you use your phone as an alarm, this is a good argument for a cheap clock.

Minutes 7 to 15: deal with your neck and shoulders

Most of us carry the whole day between the base of the skull and the top of the shoulder blades. Warmth plus gentle pressure is the fastest way to persuade that area to let go.

Ten minutes with a heated neck stretcher and shoulder massager while you sit is enough. If you would rather not use a device, a warm shower aimed at the back of your neck followed by five slow shoulder rolls does a similar job.

Minutes 16 to 20: get horizontal before you get into bed

Lie down on the sofa or the floor with your knees bent and let your head be properly supported. A supportive neck pillow helps here, because the neck cannot release while it is still doing the work of holding your head up.

Breathe out for longer than you breathe in. Four counts in, six or seven out. Do that ten times. That is the whole technique, and it is genuinely the most reliable part of the routine.

Why the same twenty minutes matters more than the perfect twenty minutes

Routines work through repetition, not through content. If you do a mediocre wind-down four nights a week, you will feel the difference within a fortnight. If you do a beautiful one once, you will not. Pick the version you can do when you are tired and slightly fed up, because that is the night it actually matters.
