10 Common Sleep Disorders
Common Sleep Disorder #5: Narcolepsy
Circadian or sleep-wake cycle is a biological clock which helps you to rest or wake up at particular times in each 24-hour cycle. It is the reason why we wake up in the morning and remain alert through the day, and sleep during the night.
Narcolepsy occurs when a person’s circadian cycle is thrown into confusion. This leads to sleepiness during the day that may go on for seconds or minutes. This exposes narcoleptics to danger especially if they drive or work with machines. Narcolepsy may also cause sleep disruptions including waking up at night. Other symptoms of narcolepsy include droopy eyelids, blurred vision and sleep paralysis.
