Evidence-based ways to sleep better

Six areas to understand, with different roles in better sleep.

These aren’t six interchangeable tips — they sit at different levels, from the first-line treatment recommended in clinical guidelines to when it’s worth involving a clinician.

Supportive

Sleep habits

Timing, light, your sleep environment, and everyday habits that can support sleep.

Mind

Sleep anxiety

Breaking the loop where worrying about sleep becomes the thing preventing it.

Practice

Relaxation

Structured methods that lower physical arousal, and how to use them properly.

Context

Lifestyle

Caffeine, alcohol, exercise, shift work — what the evidence supports and what it doesn’t.

Clinical care

Professional treatment

When to see a clinician, what they can offer, and how medication fits.

Not everyone needs every approach — what helps depends on the individual, and this page does not recommend a treatment for you personally.

What to Do When You Can’t Sleep

What to do—and what to avoid—when you’re awake at night, without turning sleep into another thing you have to solve.

When to get professional help

An occasional rough night rarely needs a clinician. Persistent sleep problems, or sleep problems that are significantly affecting your day, are a different matter.

When to talk to a doctor

Consider a conversation with a healthcare professional if you notice:

  • Persistent sleep problems that are affecting your daytime functioning
  • Loud snoring, gasping, or pauses in breathing during sleep
  • Excessive daytime sleepiness
  • An uncomfortable urge to move your legs, especially when resting or trying to sleep
  • Physical symptoms — such as pain or reflux — that repeatedly disrupt your sleep

How we decide what goes on this site

Evidence standards

We prioritise systematic reviews, clinical guidelines and randomised trials. Where evidence is weak or mixed, we say so on the page rather than leaving it out.

Medical review

Clinical content is developed from established guidelines and primary research. Where a page has undergone independent medical review, the reviewer and review date are clearly identified.

Source transparency

Claims are cited inline and linked to the primary source. We take no funding from supplement, mattress or device companies.

This site is an educational resource. It does not provide diagnosis or treatment and is not a substitute for care from a qualified clinician.
