A wake disorder, often called a Circadian Rhythm Sleep-Wake Disorder (CRSWD), happens when your internal body clock (circadian rhythm) gets out of sync with the external day-night cycle, leading to insomnia, excessive sleepiness, and irregular sleep patterns. These disorders disrupt your natural sleep-wake schedule, causing problems like jet lag, but can be chronic and affect people with shift work, neurodegenerative diseases (like Alzheimer's), developmental disorders, or even blindness.
Sleep-wake disorders occur when the body's internal clock does not work properly or is out of sync with the surrounding environment. The Circadian System. The body has an internal timing system called the circadian system that regulates daily behavior and bodily functions through cycles called circadian rhythms.
Non‐24‐hour sleep‐wake disorder (N24SWD) is a relatively rare disorder that is often observed in the visually impaired and those who isolate indoors. 1 , 2 , 3 In addition to lifestyle guidance and high‐intensity light therapy, the use of vitamin B12 and sleeping pills is recommended for treatment. 1 , 2 , 4 , 5 , 6 ...
Circadian Rhythm Sleep Disorders. Circadian rhythm sleep disorders occur when people's internal sleep-wake schedule (clock) does not align with the earth's cycle of darkness (night) and light (day).
Your doctor may suggest that you try light therapy to treat some types of circadian rhythm disorders. With this approach, you plan time each day to sit in front of a light box, which produces bright light similar to sunlight. Light visors and light glasses may also be effective.
Disruptions of your sleep-wake cycle that interfere with daily activities may mean that you have a circadian rhythm disorder. Disruptions in your sleep patterns can be temporary and caused by your sleep habits, job, or travel.
The 3-2-1 bedtime method is a simple sleep hygiene strategy: stop eating 3 hours before bed, stop working 2 hours before bed, and stop using screens (phones, tablets, TVs) 1 hour before sleep, helping your body transition to rest by reducing stimulants and digestive load for better sleep quality. A more detailed version adds 10 hours (no caffeine) and 0 (no snoozing) for a 10-3-2-1-0 rule.
The Dawn Phenomenon. Between 3 AM and 6 AM, your body prepares to wake by releasing cortisol and growth hormone — part of the natural circadian process. In some people, especially those with insulin resistance or suboptimal glucose control, this can cause an early spike in blood sugar and restlessness.
Confusional arousals can occur at any age, but are more common in children. Sleep disruptions caused by health problems (such as fever), travel, abrupt sleep loss, migraine, and irregular sleep-wake schedules may trigger an episode.
There are several different types of sleep-wake disorders, of which insomnia is the most common. Other sleep-wake disorders include obstructive sleep apnea, parasomnias, narcolepsy, and restless leg syndrome. Sleep difficulties are linked to both physical and emotional problems.
Disruption of the natural circadian rhythm has been correlated with several adverse health outcomes, including cancer [11, 12], neurodegenerative [13] and cardiovascular diseases [14], type 2 diabetes [15], endocrine [11] and gastrointestinal disorders [16].
Keep light, noise and the temperature at levels that are comfortable and won't disturb your rest. Don't do activities other than sleeping or sex in your bedroom. This will help your body know this room is for sleeping. Put clocks in your bedroom out of sight.

Anxiety and cognitive distortions seen in various psychiatric disorders can also contribute to hyperarousal seen in insomnia and perpetuate chronic insomnia. The same pathophysiological mechanisms that cause psychiatric disorders, such as depression, anxiety, and psychosis, can also cause insomnia or hypersomnia.
Schizophrenia (SCZ) patients have experience reduced sleep time, increased sleep onset, and decreased slow-wave sleep. Sleep disorders, such as insomnia and restless leg syndrome, are linked to impaired cognitive functioning in SCZ patients.
Sleep anxiety is a feeling of fear or stress about falling asleep or staying asleep. Sleep problems and mental health disorders like anxiety are closely intertwined. One can often make the other worse, so it can feel like a never-ending cycle. But anxiety and sleep issues are both treatable.
Confusional arousals
They may moan or call out briefly but do not appear fully awake. Up to 17% of children have confusional arousals, and they are most common between the ages of 2 and 5 years.
The AASM continues to recommend scoring hypopneas in adults when there is a ≥ 3% oxygen desaturation from pre-event baseline and/or the event is associated with an arousal.
The five key signs of narcolepsy, often remembered by the acronym CHESS, are Cataplexy (sudden muscle weakness), Hallucinations (vivid dream-like images), Excessive Daytime Sleepiness (EDS), Sleep Paralysis (inability to move when falling asleep or waking), and Sleep Disruption (fragmented nighttime sleep). These symptoms reflect a disruption between wakefulness and REM sleep, with elements of sleep intruding into the waking state.
Waking Between 3 am and 5 am: Lungs
This is the time when the lungs are most active, governing respiration and energy intake. Waking up during these hours might indicate an imbalance in the lungs, often tied to unresolved grief.
Best Foods for Sleep
Environmental factors, sleep disorders, and health conditions can contribute to waking at 3 a.m. Daytime disruptions to circadian rhythm or lifestyle may influence the risk of waking from sleep. A consistent sleep schedule and bedtime routine helps to promote sleep quality and duration.
In his piece, he revealed that through his years of research, he's found that rumination is the biggest thing that causes poor sleep. He says that being worried about something at night has affected his own ability to fall asleep.
Our circadian rhythm functions by light and dark cycles and therefore an ideal sleep time is 10pm – 6am give or take ½ an hour either way so a full 8 hours of sleep is achieved each night. Even if you are retired or not working, this is an essential component of good sleeping habits.
