Escala de sonolência de Epworth

What is the Epworth Sleepiness Scale?

A Epworth Sleepiness Scale is a simple questionnaire designed to measure your general level of daytime sleepiness. It asks how likely you are to doze off in common situations – like watching TV, sitting in traffic, or reading – and gives you a score from 0 to 24. The higher your score, the sleepier you are likely to be during the day.

Healthcare professionals often use this tool to help identify sleep disorders, such as apneia obstrutiva do sono ou narcolepsia.

Once you’ve added up your answers, your total score can be interpreted as follows:

• 0–7: Unlikely to be abnormally sleepy

• 8–9: Average daytime sleepiness

• 10–15: Excessive daytime sleepiness – consider seeing a doctor

• 16–24: Severely sleepy – medical advice strongly recommended

A high score doesn’t diagnose a condition on its own, but it can indicate that further investigation is needed.

Feeling excessively sleepy during the day can be caused by a range of issues, including:

• Poor sleep quality or insufficient sleep

• Distúrbios do sono such as obstructive sleep apnoea, síndrome das pernas inquietas, or insônia

• Narcolepsia, a neurological disorder that disrupts sleep–wake cycles

• Shift work, jet lag, or irregular sleep patterns

• Mental health issues like depressão ou ansiedade

• Medicamentos ou álcool that cause drowsiness

• Underlying medical conditions such as hypothyroidism or síndrome da fadiga crônica

Understanding the root cause is key to managing daytime drowsiness effectively.

You should consider speaking to your GP or a sleep specialist if:

• Your Epworth score is 10 or higher

• You often struggle to stay awake during the day

• Your sleepiness is affecting your work, relationships, or safety

• You snore heavily, stop breathing during sleep, or wake up feeling unrefreshed

• You experience sudden sleep attacks, especially while talking, eating, or driving

Excessive sleepiness isn’t something to ignore – it can be a sign of an underlying condition that’s both treatable and important for your long-term health.
