Nightmares Night & Terrors
Sleep dysfunctions in children, such as fragmented sleep, sleep deprivation, or irregular sleep patterns, can contribute to nightmares and night terrors in several ways. Here’s how sleep dysfunctions are linked to these disturbances:
- Sleep Deprivation and Fragmented Sleep
- Sleep Disorders and Breathing Issues
- Sleep Disorders and Breathing Issues
- Anxiety and Stress
- Impact of Inconsistent Sleep Schedules
- Medication or Illness
Summary of the Relationship:
- Nightmares are primarily related to disturbances in REM sleep, with emotional stress and fragmented sleep being major triggers.
- Night Terrors are linked to disruptions in deep non-REM sleep, often triggered by sudden arousals due to sleep dysfunctions like overtiredness, irregular schedules, or conditions such as sleep apnea.

Sleep dysfunctions in children, such as fragmented sleep, sleep deprivation, or irregular sleep patterns, can contribute to nightmares and night terrors in several ways. Here’s how sleep dysfunctions are linked to these disturbances:
1. Sleep Deprivation and Fragmented Sleep
- Increased Nightmares: When children are sleep-deprived or experience fragmented sleep (due to frequent waking or poor sleep quality), their brain may spend more time in REM (rapid eye movement) sleep during subsequent sleep cycles to “make up” for the lack of rest. REM sleep is the phase where most dreaming occurs. This increase in REM sleep can lead to more vivid and distressing dreams, which may result in nightmares.
- Impact on Emotional Regulation: Sleep deprivation impairs the brain’s ability to regulate emotions. This can make children more prone to experiencing intense emotions during dreams, which can manifest as nightmares. Anxieties or unresolved fears might be amplified in their dreams.
2. Night Terrors and Disrupted Deep Sleep (NREM)
- Night Terrors Linked to Non-REM Sleep: Unlike nightmares, which occur during REM sleep, night terrors typically occur during deep non-REM sleep (specifically in the transition from Stage 3 or slow-wave sleep). Night terrors usually arise when there’s a sudden arousal from deep sleep, which can be triggered by underlying sleep dysfunctions.
- Sleep Disruptions and Arousal from Deep Sleep: Factors such as overtiredness, irregular sleep schedules, or sleep disorders (e.g., sleep apnea) can cause frequent disruptions during non-REM sleep. These disturbances lead to incomplete arousal from deep sleep, which can manifest as night terrors. The child may wake up suddenly, often screaming or appearing fearful, but they won’t remember the episode the next morning.
3. Sleep Disorders and Breathing Issues
- Obstructive Sleep Apnea (OSA): Children with sleep apnea may experience frequent awakenings or difficulty breathing during sleep, which can lead to sleep fragmentation. The lack of restful sleep and oxygen disruptions during the night can contribute to both nightmares and night terrors.
- Disrupted Sleep Cycles: Any condition that disrupts a child’s natural sleep cycle, including breathing issues or frequent awakenings, increases the likelihood of abnormal arousals from different sleep stages, contributing to both types of sleep disturbances.
4. Anxiety and Stress
- Relationship with Sleep Dysfunctions: Anxiety and stress can disrupt sleep in children, leading to difficulty falling asleep or staying asleep. Children who experience stress may have more vivid or distressing dreams (nightmares). In addition, night terrors can be triggered by emotional stress or anxiety, particularly in children who are already predisposed to irregular sleep patterns.
- Overactive Nervous System: Sleep dysfunctions can overstimulate the autonomic nervous system (responsible for the “fight or flight” response), which can increase the likelihood of experiencing night terrors during the deep stages of sleep.
5. Impact of Inconsistent Sleep Schedules
- Irregular Bedtimes: An inconsistent sleep schedule can cause disruptions in the natural circadian rhythm, leading to poor-quality sleep. This irregularity can cause more frequent transitions between sleep stages, increasing the chances of nightmares and night terrors.
- Lack of Sleep Routine: A lack of a calming bedtime routine can lead to a buildup of anxiety at bedtime, making children more prone to nightmares or night terrors as their brain tries to process stress during sleep.
6. Medication or Illness
- Certain Medications: Some medications, such as those that affect the central nervous system or alter sleep patterns, can increase the likelihood of nightmares or night terrors.
- Illness and Fever: When a child is sick or has a fever, their sleep can become more fragmented, and they may be more prone to nightmares or night terrors due to the disrupted sleep patterns caused by illness.
Summary of the Relationship:
- Nightmares are primarily related to disturbances in REM sleep, with emotional stress and fragmented sleep being major triggers.
- Night Terrors are linked to disruptions in deep non-REM sleep, often triggered by sudden arousals due to sleep dysfunctions like overtiredness, irregular schedules, or conditions such as sleep apnea.
