It persists during the transition of sleep to wakefulness, where an individual will experience feelings of drowsiness, disorientation and a decline in motor dexterity.
A confusional arousal (also known as sleep drunkenness or severe sleep inertia) is medical condition where a person awakened from sleep shows mental confusion for at least several minutes. [ 1 ] [ 2 ] Complete or partial amnesia of the episodes may be present.
This could, conceivably, contribute to the excessive sleep inertia upon awakening that is often reported by those with DSPD. It has also been hypothesized that, due to the altered phase angle between sleep and temperature observed in DSPD, and the tendency for longer sleep periods, these individuals may simply sleep through the phase-advance ...
Waking up tired is often due to sleep inertia, but sleep environment and habits also play a part. Here, doctors provide tips for waking up refreshed.
[27] [28] Scientific studies on sleep have shown that sleep stage at awakening is an important factor in amplifying sleep inertia. [29] Determinants of alertness after waking up include quantity/quality of the sleep, physical activity the day prior, a carbohydrate-rich breakfast, and a low blood glucose response to it. [30]

[1] [2] During an episode, the person may hallucinate (hear, feel, or see things that are not there), which often results in fear. [1] [3] Episodes generally last no more than a few minutes. [2]
A predicted 800,000 people could benefit, officials said.
EDS can be a symptom of a number of factors and disorders. Specialists in sleep medicine are trained to diagnose them. Some are: Insufficient quality or quantity of night time sleep [5] Obstructive sleep apnea [6] Misalignments of the body's circadian pacemaker with the environment (e.g., jet lag, shift work, or other circadian rhythm sleep ...
