😴Microsleep / Terlelap seketika

Microsleep: Brief Sleep Episodes That Signal Dangerous Sleep Deprivation

Microsleep refers to very brief, involuntary episodes of sleep lasting a few seconds, often occurring without the person realising it. During microsleep, the brain momentarily shuts down, even though the eyes may remain open.

Microsleep is extremely dangerous, especially when it occurs while driving, working, or operating machinery. As an ENT specialist, I consider microsleep a strong indicator of severe sleep deprivation, most commonly caused by untreated obstructive sleep apnoea (OSA).

Why Does Microsleep Occur?

Microsleep happens when the brain is overwhelmed by sleep pressure.

Common causes include:

Severe sleep fragmentation from sleep apnoea
Loud snoring with repeated arousals
Chronic sleep deprivation
Night shift work
Alcohol or sedative use

Among these, sleep apnoea is the most common medical cause.

A woman with a distressed expression covers her ears while a man sleeps peacefully beside her in a dimly lit bedroom. — Snoring and obstructive sleep apnea are leading contributors to microsleep episodes.

🚨 Why Is Microsleep Dangerous?

Microsleep can lead to:

Road traffic accidents
Workplace injuries
Near-miss incidents
Reduced reaction time
Poor decision-making

Many serious accidents occur without warning, as the individual may not realise they briefly fell asleep.

How an ENT Specialist Evaluates Microsleep

ENT assessment focuses on identifying sleep-disordered breathing:

Detailed sleep and accident history
Snoring and apnoea screening
Daytime sleepiness assessment
Nose, throat, jaw, and neck examination
Flexible nasoendoscopy
Referral for sleep study

This helps confirm whether microsleep is linked to airway obstruction during sleep.

Treatment Options

✅ Treat the Underlying Cause

CPAP therapy for confirmed OSA
Treatment of nasal obstruction
Weight reduction

Turbinoplasty – nasal procedure to improve nasal airway for better sleep

✅ Safety Measures (Short Term)

Avoid driving when sleepy
Take breaks during long journeys
Avoid alcohol before sleep

A man sleeping in a car with a truck passing by on the road, and a large sign overhead that reads 'DO NOT DRIVE WHEN SLEEPY'. — A man asleep at the wheel, highlighting the dangers of driving while sleepy, with a warning sign in the background.

Effective treatment often eliminates microsleep episodes completely.

Frequently Asked Questions

Is microsleep the same as being tired?
No. Microsleep involves brief, involuntary sleep.

Can microsleep happen with eyes open?
Yes. This makes it particularly dangerous.

Does coffee prevent microsleep?
No. It may delay but does not prevent it.

When Should You See an ENT Specialist in Kuala Lumpur?

Consult an ENT specialist urgently if:

You experience blank moments
You have near-miss accidents
You snore loudly
Someone reports breathing pauses
You feel excessively sleepy during the day

Early assessment can prevent serious injury or death.

Excessive daytime sleepiness is typically accompanied by frequent episodes of microsleep

👨‍⚕️ ENT Specialist’s Perspective

Microsleep is a red-flag symptom of severe sleep disruption. From an ENT perspective, it often reflects untreated airway obstruction during sleep. Identifying and treating sleep apnoea not only improves alertness but can be life-saving.
