Why the hour before bed matters

Most of us treat sleep as something that happens the moment our head touches the pillow. In reality, your body needs a runway. It needs to know that the day is winding down, that the lights are dimming and that it is safe to let go. The roughly ninety minutes before bed are when your core temperature begins to drop, your melatonin starts to rise and your nervous system shifts out of alert mode. Rush that transition and you can spend the first hour in bed simply waiting.

The good news is that you do not need an elaborate ritual or expensive gadgets. A gentle evening routine is mostly about repetition and small signals: lower light, less noise, a warm drink and a little quiet. Do it often enough and your body starts to recognise the pattern and meet you halfway.

Dim the lights before you dim yourself

Light is the strongest signal your body has for telling day from night. Bright overhead lighting in the evening, especially the cool white kind, tells your brain it is still mid-afternoon. Try switching off the ceiling light once the washing-up is done and using two or three lamps instead. A warm bulb, somewhere around 2700K, gives a soft golden glow that feels far more forgiving than a bright kitchen downlight.

• Use lamps rather than overhead lights from around 8pm, or two hours before bed if you can manage it.
• Keep one lamp low and to the side, so the light sits beside you rather than shining into your face.
• Close the curtains and let the room settle into its evening mood.
• Candles are lovely in winter, but if you use them, keep them well away from curtains and never leave them burning as you head upstairs.

You will notice the difference within a week. Dim light makes a room feel calmer, and calm rooms make sleepy people.

Put your screens to bed before you do

Phones and laptops are not evil, but they are brightly lit, endlessly interesting and very good at keeping you awake. A practical approach is to give them a bedtime of their own, perhaps an hour before yours. If that sounds drastic, start with forty minutes and see how it feels.

• Charge your phone across the room, or better still, downstairs in the kitchen.
• Turn off notifications rather than relying on willpower alone.
• Swap scrolling for something you can hold: a paperback, a magazine, a crossword.
• If you use your phone as an alarm, buy a cheap bedside clock instead and retire the phone from the bedroom entirely.

The first two evenings may feel oddly empty. By the fourth, most people find they are reading more and thinking less.

A warm drink and a small comfort

There is a reason a mug of something warm feels like being looked after, and it is not only psychological. A warm drink raises your core temperature slightly, and the gentle drop that follows helps nudge you towards sleep. Keep it caffeine-free after about 2pm, and go easy on alcohol, which may help you nod off but tends to wake you in the small hours.

• Chamomile, lemon balm, peppermint or a milky rooibos all work well.
• Warm milk with a teaspoon of honey is a classic for good reason.
• Keep the mug small, so you are not waking at 3am needing the bathroom.
• Pair it with a biscuit, a square of dark chocolate or a slice of toast if you are genuinely peckish.

Make the drink slowly and drink it sitting down, away from the sink and the to-do list. Half the benefit is in the pause, not the tea.

The last hour, step by step

If you like a bit of structure, this is a simple shape for the final hour. Adjust it to suit your household, but keep the order roughly the same so it becomes automatic.

• Clear one small thing. Wipe the kitchen surfaces, set out tomorrow's mugs, lay out your clothes. A tidy room is easier to leave alone.
• Warm up, then cool down. A bath or shower about an hour before bed raises your temperature; the drop afterwards is a powerful sleep signal.
• Get ready for bed properly. Brush your teeth, wash your face, put on something comfortable. Doing this earlier stops it becoming a chore at midnight.
• Sit somewhere soft. A chair or the end of the bed rather than the sofa in front of the television.
• Read, stretch or write. A few lines in a notebook, a gentle shoulder stretch, three pages of a novel. Nothing that requires a screen or a decision.
• Keep the bedroom cool and dark. Around 16 to 18 degrees suits most people, and a hot water bottle at the foot of the bed in winter is a small, reliable pleasure.

Keeping it gentle, not perfect

A routine is there to help you, not to give you another thing to fail at. Some evenings you will get home late, eat too much and fall asleep on the sofa. That is fine. What matters is returning to the pattern the next night, without scolding yourself for the one before.

Try to go to bed and get up at roughly the same time each day, including weekends, because your body clock favours consistency over length. If you cannot sleep after twenty minutes, get up, sit somewhere dim and read until you feel drowsy, then try again. And be patient: a new routine takes a fortnight or so to settle into the bones. Dim the lights, put the phone away, make the drink. The rest tends to follow.
