Falling Asleep in Meetings: Microsleep vs. Excessive Daytime Sleepiness

Do you find yourself nodding off during presentations or “falling asleep in meetings”? You’re not alone. Many adults experience unexpected sleep episodes when they least expect them. Understanding whether these episodes are microsleeps or a sign of excessive daytime sleepiness (EDS) can help you take the right steps for better health and productivity.

What Is Microsleep?

Microsleeps are extremely brief sleep episodes—often just a few seconds—when you’re otherwise awake. During a microsleep, you may:

• Lose awareness of your surroundings
• Stare blankly ahead
• Experience a sudden head drop

Microsleeps occur most often when you’re very tired, doing monotonous tasks, or driving. They happen without warning and can last from 1 to 30 seconds, making you feel like you “snapped out of it” when you realize you’ve missed a few seconds of conversation or action.

What Is Excessive Daytime Sleepiness (EDS)?

Excessive daytime sleepiness is more than just feeling tired. It’s a persistent struggle to stay awake during normal waking hours, even after a full night’s sleep. You might:

• Struggle to stay alert in meetings or lectures
• Find it hard to keep your eyes open while reading
• Nodding off during quiet moments

EDS can significantly impact work, relationships, and safety. It may signal an underlying sleep disorder or other health issues.

How Experts Measure Daytime Sleepiness

1. Epworth Sleepiness Scale (ESS)
   Developed by Johns MW. (1991) for measuring general daytime sleepiness. You rate your likelihood of dozing in eight everyday situations. A higher score suggests greater sleepiness.

2. Multiple Sleep Latency Test (MSLT)
   Established by Carskadon MA, Dement WC, Mitler MM, et al. (1986) as a standard measure in sleep labs. You take brief naps every two hours, and technicians record how quickly you fall asleep. Short latencies point to severe sleepiness.

These tools help your healthcare provider determine if your daytime sleepiness is within a normal range or indicates a sleep disorder.
