How to fix my sleep: a practical reset that holds.

Most people trying to fix their sleep start with the wrong lever: they try to fall asleep earlier. Sleep responds far better to a fixed wake time, daylight and a predictable wind-down than it does to lying in bed trying harder.

Step one: anchor your wake time

Choose one wake time and keep it seven days a week, including weekends, for two to three weeks. Your body clock is set mainly by when you get up and see light, not by when you go to bed. Bedtime will gradually follow the wake time once the drive to sleep rebuilds.

Step two: use light deliberately

Get outside for ten to twenty minutes within an hour of waking, even on a grey Irish morning — outdoor light is far brighter than indoor lighting. In the evening, dim the lights and reduce screen brightness for the last hour. Light in the morning advances your clock; light late at night delays it.

Step three: fix the obvious chemistry

Caffeine has a half-life of around five hours, so an afternoon coffee is still active at bedtime. Set a cut-off eight hours before bed. Alcohol is sedating but fragments the second half of the night and worsens snoring and breathing events, so it is one of the most common hidden causes of unrefreshing sleep.

Step four: shorten your time in bed, not lengthen it

If you lie awake for long stretches, spending more time in bed usually makes it worse. Go to bed only when sleepy, and if you are awake for more than about twenty minutes, get up, do something quiet and dim, and return when sleepy. This is the core of cognitive behavioural therapy for insomnia (CBT-I), the recommended first-line treatment for chronic insomnia.

Step five: make the room boring

Cool, dark and quiet. A slightly cool room helps the drop in core temperature that accompanies falling asleep. Remove clocks you check, and keep the bed for sleep and sex so the association stays strong.

When better habits are not the answer

If you follow a consistent routine and still wake unrefreshed, the problem may not be behavioural. Obstructive sleep apnoea, restless legs, chronic pain, thyroid problems, depression and anxiety all disrupt sleep quality independently of habits. Loud snoring, witnessed pauses in breathing, morning headaches and heavy daytime sleepiness are the strongest clues that breathing is the issue.

In that case, a home sleep test measures what is actually happening while you sleep, rather than asking you to guess. A clinician reviews the recording and you receive a call explaining the result and a recommendation on what to do next.
