Around one in three people in the UK has trouble sleeping at some point. Insomnia usually starts with a trigger: stress at work, illness, travel, a new baby or a shift in daylight like the one that came when the clocks went back on 25th October.

What turns a few bad nights into months of insomnia is usually the way you respond to them. Lying in to make up for lost sleep, going to bed earlier, napping and lying awake worrying all weaken your body clock and train your brain to link bed with being awake. The habits below reverse that pattern. They come from cognitive behavioural therapy for insomnia, known as CBT-I, which UK guidance now recommends before sleeping pills.

## Keep One Wake-Up Time, Seven Days a Week

Your body clock anchors itself to the time you get up, not the time you go to bed. Set one alarm time and keep it at weekends. A lie-in of two or three hours on Saturday and Sunday works like a small dose of jet lag, which makes Sunday night and Monday morning harder.

## Get Daylight Within an Hour of Waking

Morning light is the strongest cue your body clock receives. Even on an overcast November morning, daylight outdoors is many times brighter than the lighting in your kitchen. Spend 10 to 20 minutes outside early in the day: walk part of your commute, take your coffee to the garden or step out at lunch if your mornings are dark.

## Go to Bed Only When You Are Sleepy

Tired and sleepy feel different. Tired means drained, while sleepy means your eyes are closing and your head is nodding. If you go to bed tired but alert, you give yourself extra time to lie awake. Stay up in dim light until sleepiness arrives, then go to bed.

## Keep Your Bed for Sleep and Sex

When you work, scroll or watch television in bed, your brain starts to treat the bed as a place for being awake. If you lie awake for what feels like about 20 minutes, get up, go to another dimly lit room and do something calm, such as reading a printed book, until you feel sleepy again. Turn your clock to face the wall, as checking the time feeds anxiety about the hours you are losing.

## Do Not Try to Catch Up After a Bad Night

Your drive to sleep builds the longer you stay awake, and a poor night leaves you with plenty of it. Long naps and early nights spend that drive before you need it. If you must nap, keep it under 20 minutes and finish before 3pm.

## Stop Caffeine by Early Afternoon

Caffeine stays active in your body for many hours, and half of a dose is often still in your system five or six hours later. A 4pm coffee can still be working at midnight. Set a cut-off around 2pm, and count tea, cola, energy drinks and dark chocolate as caffeine too.

## Treat Alcohol as a Sleep Disruptor

A glass of wine can help you drop off, but alcohol breaks up the second half of the night and cuts the dream sleep that leaves you feeling restored. If you drink, keep it small and finish at least three hours before bed.

## Keep Your Bedroom Cool and Dark

Your body temperature needs to fall a little for sleep to begin, and a bedroom of around 16 to 18°C makes that easier. Use blackout blinds or an eye mask, and try earplugs or a fan for steady background sound if traffic or a partner wakes you.

## Give Your Mind a Wind-Down Hour

Write tomorrow's to-do list and any worries on paper in the early evening, so you do not rehearse them in bed. In the last hour before sleep, dim the lights and put your phone in another room. Absorbing messages, news and games keep your mind switched on for longer than the screen light does.

## Move Every Day, Earlier Rather Than Later

Regular exercise helps you fall asleep faster and sleep more deeply. A brisk daytime walk counts. Finish hard workouts at least two or three hours before bed, so your heart rate and body temperature have time to settle.

## When to See Your GP About Insomnia

See your GP if poor sleep has lasted several weeks, if it affects your work or mood or if these habits have not helped. Your GP can check for causes such as sleep apnoea, restless legs, an overactive thyroid or medication side effects. Loud snoring with pauses or gasps is worth raising straight away.

For long-term insomnia, CBT-I is the first treatment offered in the UK. You can get it through NHS Talking Therapies, where you can refer yourself in England, or through digital programmes such as Sleepio, which some NHS areas offer free. Sleeping pills are for short-term use only, as the benefit fades and dependence can follow.
