Calculate your level of sleepiness

Sleepiness

Healthy adults may experience sleepiness at their normal bedtime or even mid-afternoon. Daytime sleepiness is considered excessive when it occurs at unusual times.

Excessive daytime sleepiness directly affects the individual and also those close to him or her. Sleepiness can have serious consequences, be it personal, family or professional.

Epworth Sleepiness Scale

Sleepiness can be measured objectively in the laboratory and subjectively by autoquestionnaire. Objective sleepiness is measured by the maintenance of wakefulness test (MWT) and requires polysomnography. Usually, subjective sleepiness is measure by the Epworth Sleepiness Scale (ESS). The ESS is a simple and short duration tool assessing the probability of falling asleep in various situations. ESS score may decrease with appropriate positive pressure treatment.

Sleepness Scale (1 to 3) :
