Insomnia
Insomnia in Singapore: causes, treatment and when to get help
If you cannot fall asleep, keep waking through the night, or wake far too early, you are not short of willpower — you have a treatable sleep problem. This guide explains what insomnia is, what causes it here in Singapore, how it is diagnosed, and the treatments that actually work.

The short answer
Insomnia is difficulty falling asleep or staying asleep at least three nights a week, despite having the chance to sleep, with a real effect on your day. Under three months it is called acute insomnia; three months or longer is chronic insomnia. The recommended first-line treatment is not medication — it is CBT-I, a structured behavioural programme that retrains sleep timing and the anxiety loop around bedtime. Before starting any treatment, it is worth ruling out obstructive sleep apnea, which fragments sleep and is routinely mistaken for insomnia in people who snore or wake unrefreshed.
The four patterns
Insomnia does not look the same for everyone
Naming your pattern matters, because the treatment differs depending on where in the night the problem sits.
Sleep-onset insomnia
You lie awake for 30 minutes or longer at the start of the night, usually with a busy mind.
Sleep-maintenance insomnia
You fall asleep normally but wake repeatedly through the night and struggle to settle again.
Early-morning waking
You wake at 3am or 4am fully alert and cannot get back to sleep before the alarm.
Acute vs chronic
Acute insomnia lasts days to weeks after a stressor. Chronic insomnia is three nights a week for three months or more, and rarely resolves on its own.
Why it happens here
Common causes of insomnia in Singapore
Most chronic insomnia has more than one cause: something started it, and then habits formed while sleeping badly kept it going.
- Work stress, shift rotations and long hours — common in healthcare, aviation, security and F&B
- Screens and work email late at night, which delay the body clock
- Caffeine after mid-afternoon, including kopi, teh and energy drinks
- Alcohol before bed — it shortens sleep onset but fragments the second half of the night
- A bedroom that is too warm or humid without adequate cooling
- Anxiety, low mood, chronic pain, reflux, menopause and thyroid problems
- Untreated obstructive sleep apnea, which fragments sleep and is often mistaken for insomnia
The most missed cause
When insomnia is actually sleep apnea
Obstructive sleep apnea interrupts breathing dozens of times an hour. You may never remember the awakenings — you only notice that you wake often, sleep badly and feel exhausted. It is one of the most common reasons insomnia treatment fails, and it is simple to check for. If two or three of these apply to you, test before you treat.
- You snore loudly, or a partner has seen you stop breathing
- You wake gasping, choking, or with a dry mouth
- You wake several times a night without knowing why
- You sleep a full night and still wake unrefreshed
- You are sleepy during the day, or nod off in meetings or while driving
- You have high blood pressure, diabetes or are carrying extra weight
Getting a diagnosis
How insomnia is assessed in Singapore
1. A conversation, not a scan
Insomnia is diagnosed clinically. A GP, polyclinic doctor or sleep clinician asks about your nights, your daytime function, your medication and your mood. No scan diagnoses insomnia.
2. A sleep diary
One to two weeks of bed times, wake times and night wakings. It is the single most useful thing you can bring to a first appointment, and it is what CBT-I is built on.
3. A sleep test, if indicated
A sleep study is not needed for straightforward insomnia. It is needed when snoring, witnessed pauses, or unrefreshing sleep suggest apnea. A home sleep test answers that in one night, in your own bed.
Treatment
What actually works — in order
International guidelines are consistent on this: behavioural treatment first, medication second and short-term, and any underlying sleep disorder treated in parallel.
| Treatment | What it involves | Best suited to |
|---|---|---|
| CBT-I (cognitive behavioural therapy for insomnia) | The internationally recommended first-line treatment for chronic insomnia — ahead of medication. It retrains sleep timing, sleep drive and the anxiety loop around bedtime, typically over six weeks. | Chronic insomnia, three months or longer |
| Sleep scheduling and stimulus control | A fixed wake time, getting out of bed when you cannot sleep, and reserving the bed for sleep only. These are the two components of CBT-I that do most of the work. | Everyone, including acute insomnia |
| Treating an underlying sleep disorder | If your insomnia is driven by obstructive sleep apnea, restless legs or reflux, no amount of sleep hygiene fixes it. The underlying condition has to be identified and treated. | Snorers, unrefreshing sleep, frequent night waking |
| Melatonin | In Singapore melatonin is a prescription-only medicine. It helps with body-clock problems such as shift work and jet lag more than it helps classic insomnia. | Delayed body clock, shift work, jet lag |
| Prescription sleep medication | Sedatives and z-drugs can break a bad patch, but tolerance and rebound insomnia are real. Doctors in Singapore generally prescribe them short-term and alongside behavioural treatment. | Short-term use, under a doctor |

Insomnia questions we hear most
How do I know if I have insomnia or just a few bad nights?
Insomnia is diagnosed when difficulty falling asleep or staying asleep happens at least three nights a week, causes real daytime impact, and there is adequate opportunity to sleep. Under three months it is acute insomnia; three months or longer is chronic insomnia and is worth treating properly.
Where can I get treated for insomnia in Singapore?
Start with a GP or polyclinic, who can rule out medical causes and refer you onward. Sleep clinics at the restructured hospitals and private sleep and psychology practices offer CBT-I. If snoring or unrefreshing sleep is part of the picture, a home sleep apnea test is a sensible first step because it is faster and can be done in your own bed.
Is CBT-I better than sleeping pills?
For chronic insomnia, yes. Clinical guidelines worldwide recommend CBT-I as first-line treatment because its effects last after the programme ends, whereas medication generally works only while you keep taking it and can cause rebound insomnia when stopped.
Can sleep apnea cause insomnia?
Yes, and it is frequently missed. Obstructive sleep apnea repeatedly interrupts breathing during the night, which fragments sleep and produces frequent waking that feels exactly like insomnia. People in this group often get treated for insomnia for years with no improvement until the apnea is identified.
Can I buy melatonin over the counter in Singapore?
No. Melatonin is a prescription-only medicine here, unlike in the United States where it is sold as a supplement. You need to see a doctor for it, and it is more useful for body-clock problems such as shift work and jet lag than for classic insomnia.
How much does a sleep test cost in Singapore?
A home sleep apnea test with Comooz is $189 (usual $269), including doorstep delivery and collection of the kit islandwide. An in-lab study at a hospital costs considerably more and usually involves a waiting list.
How long does it take to fix insomnia?
A structured CBT-I programme usually runs about six weeks, with most people noticing a change in the second or third week. If an underlying sleep disorder such as apnea is driving the problem, improvement follows treatment of that condition instead.
Does insomnia go away on its own?
Acute insomnia after a specific stressor often does. Chronic insomnia usually does not, because the habits formed while sleeping badly — long time in bed, irregular wake times, anxiety about sleep — keep it going after the original trigger has passed.
