Sleep: create the right conditions.

Why Sleep Matters

Sleep affects almost every part of health. It influences mood, memory, concentration, immunity, blood pressure, weight regulation, diabetes risk, heart health and mental wellbeing.

Most adults need around 7-9 hours, but sleep quality matters too. A long night of broken, restless sleep can feel very different from a shorter night of settled sleep.

How Sleep Actually Works

Two main systems help control sleep: sleep pressure and your body clock. Good sleep usually needs both working together.

1. Sleep pressure

Sleep pressure is like a balloon slowly inflating through the day. The longer you are awake, the more sleepy pressure builds. Sleeping releases that pressure.

Some things can let pressure out of the balloon before bedtime: long naps, dozing on the sofa, or spending hours lying in bed half-awake.

2. Your body clock

Your body clock is an internal 24-hour rhythm. It likes regular cues: waking at similar times, morning daylight, meals, movement and activity during the day.

It can be disrupted by lie-ins, late nights, jet lag and shift work. This is one reason people can feel exhausted but still not be ready to sleep at the time they want to.

Why Lying Awake In Bed Can Make Things Worse

Your brain learns by association. Ideally, bed means sleep.

If bed becomes the place where you worry, scroll, watch the clock, feel frustrated or try desperately to sleep, your brain can begin to associate bed with wakefulness instead.

This is why one of the most useful insomnia strategies is also one of the least intuitive: if you are awake for a while, get up. Do something quiet and unstimulating, then return when sleepy.

Build A Strong Sleep Routine

Morning

• Wake at roughly the same time each day.
• Get outside within 30-60 minutes if you can.
• Move your body.

Daytime

• Exercise regularly.
• Avoid long naps.
• Limit caffeine after lunchtime.
• Stay socially engaged.

Evening

• Dim the lights.
• Reduce stimulating activities.
• Create a wind-down routine.
• Remember that alcohol may help you fall asleep, but often makes sleep lighter and more broken later in the night.

Bedtime

• Only go to bed when sleepy.
• If you are awake for around 20-30 minutes, get up.
• Read, listen to relaxing music, or do something quiet.
• Return to bed when sleepy.

This idea comes from stimulus control, one of the core behavioural tools used in Cognitive Behavioural Therapy for Insomnia, or CBT-I.

Why CBT-I Matters

CBT-I is not just general sleep hygiene. Sleep hygiene is useful, but on its own it often is not enough for persistent insomnia.

CBT-I looks at the patterns that keep insomnia going: spending too much time awake in bed, losing confidence in sleep, worrying about the consequences of a bad night, napping to survive the day, or changing routines in ways that accidentally weaken sleep pressure.

It usually includes several practical elements:

• Stimulus control: rebuilding the connection between bed and sleep.
• Sleep restriction or sleep scheduling: carefully matching time in bed to actual sleep, usually with guidance.
• Cognitive work: challenging frightening or unhelpful beliefs about sleep.
• Relaxation and wind-down strategies: reducing arousal without trying to force sleep.
• Sleep diary work: spotting patterns and tracking progress more accurately than memory alone.

CBT-I can feel counterintuitive at first, especially the idea of getting out of bed when you cannot sleep. But the goal is to retrain the brain and body over time, not to win one night of sleep by trying harder.

Common Sleep Myths

When Should I Seek Help?

Speak to a healthcare professional if sleep problems are persistent, affecting daily life, or if there are symptoms suggesting another sleep or health condition.

• Sleep problems lasting more than 3 months.
• Loud snoring with daytime sleepiness.
• Pauses in breathing or choking episodes at night.
• Overwhelming daytime sleepiness.
• Symptoms of anxiety or depression.
• Restless legs.
• Unusual behaviours during sleep.
