✓Well SupportedThe first half of the night features more deep non-REM sleep, while the second half features more light non-REM and REM sleep.✓Well SupportedREM sleep is involved in unlearning emotional events.✓Well SupportedThe absence of epinephrine during REM sleep allows for the processing of challenging experiences without fear and anxiety, which is important for emotional adjustment.✕Not SupportedSupplements targeting the serotonergic system for sleep can lead to fragmented sleep and difficulty in later sleep phases.✓Well Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Andrew Huberman practices a daily self-directed relaxation technique, similar to yoga nidra, involving long exhale breathing, which he calls 'non-sleep deep rest'.

✓Well SupportedSlow wave sleep is critical for motor learning and specific detail acquisition, while REM sleep is associated with emotions and general themes.

✓Well SupportedLateralized eye movements, but not vertical eye movements, suppress amygdala activity.

✓Well SupportedSerotonin levels are high during slow wave sleep, contributing to a sensation of well-being and reduced movement.

✓Well SupportedConsistently getting 6 to 6.5 hours of sleep per night is more beneficial than fluctuating sleep durations.

✓Well SupportedInsufficient REM sleep can lead to emotional irritability, catastrophizing, and feeling overwhelmed.

✓Well SupportedResistance exercise appears to increase the amount of slow wave sleep.

✓Well SupportedEMDR is an approved behavioral treatment for trauma, most effective for single-event traumas.

✓Well SupportedSleep is structured into 90-minute ultradian cycles progressing through lighter and deeper sleep phases.

✓Well SupportedREM sleep is important for solidifying relationships, discarding irrelevant meanings, and preventing odd associations.

✓Well SupportedConsistent sleep duration is more important for learning and performance than variable sleep durations.

✕Not SupportedAlcohol, THC, and substances that increase serotonin or GABA disrupt sleep patterns, depth, and the natural sequencing of slow wave and REM sleep.

◐Partially SupportedKetamine functions similarly to PCP by disrupting NMDA receptor activity.

◐Partially SupportedLateralized eye movements can be used clinically to suppress the fear response and uncouple the emotional load associated with traumatic experiences.

◐Partially SupportedREM sleep is involved in the replay of spatial information, which aids in solidifying memories of navigated environments.

◐Partially SupportedSleepwalking typically occurs during slow wave sleep.

◐Partially SupportedSlow wave sleep is involved in motor learning and detailed learning.

◐Partially SupportedKetamine is used in emergency rooms to prevent the attachment of intense emotion to traumatic experiences by blocking plasticity shortly after the event.

◐Partially SupportedDuring REM sleep, the body experiences atonia and hallucinatory experiences, with no epinephrine present.

◐Partially SupportedMenopausal disruptions in temperature and sleep regulation can impact emotionality and emotional circuit adjustment.

◐Partially SupportedREM sleep is important for discarding irrelevant meanings and maintaining narrow channels between concepts.

◐Partially SupportedNMDA receptors, when activated by intense neural activity, allow ion entry that triggers long-term potentiation, leading to changes in neural connectivity.

◐Partially SupportedKetamine blocks NMDA receptors, preventing the association of intense emotions with specific experiences.

◐Partially SupportedREM and non-REM sleep have distinct roles in learning and unlearning different types of information.

◐Partially SupportedDeprivation of slow wave sleep leads to poor performance on tests of detailed information learning.

◐Partially SupportedConsistent sleep duration, such as 6 hours nightly, is superior to inconsistent sleep durations over consecutive nights.

◐Partially SupportedDaytime activities can be leveraged to increase either slow wave sleep or REM sleep.

◐Partially SupportedSleep disturbances correlate with numerous emotional and psychological disturbances due to the role of sleep in processing emotions.

◐Partially SupportedEMDR should be performed in a clinical setting by a certified practitioner for trauma treatment.

◐Partially SupportedREM sleep deprivation can lead to seeing odd associations and, in prolonged cases, hallucinations.

◐Partially SupportedThe absence of epinephrine during REM sleep allows for the experience of emotionally laden events without fear or anxiety, facilitating unlearning.

◐Partially SupportedMastering one's sleep is important for unlearning troubling emotions and moving forward in life.

◐Partially SupportedEMDR is most successful for single-event traumas or specific recurring traumas, rather than diffuse experiences.

✕Not SupportedDrinking a lot of fluid before sleep can disrupt sleep by causing a full bladder.

◐Partially SupportedMany emotional effects of menopause in women may not be directly caused by hormonal changes.
