GUEST SERIES | Dr. Matt Walker: Improve Sleep to Boost Mood & Emotional Regulation

May 1, 2024 2h 15m 17 insights
This is episode 5 of our 6-part special series on sleep with Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology at the University of California, Berkeley and the host of The Matt Walker Podcast. In this episode, we explain the connection between sleep and mood, emotional regulation and mental well-being.  We explain the role of rapid eye movement (REM) sleep in processing emotions and emotional memories and why sleep deprivation causes agitation, impulsivity and emotional reactivity.  We also discuss why sleep disruption is a hallmark feature of PTSD, anxiety, depression, suicidality, and other psychiatric conditions.  We explain protocols for improving REM sleep and other sleep phases in order to harness the therapeutic power of quality sleep to feel calmer and emotionally restored. This episode describes various actionable tools to improve sleep for those struggling with mental health or mood and those wanting to bolster their overall state and well-being.  The next episode in this special series explores dreams, including lucid dreaming, nightmares and dream interpretation.

Actionable Insights

1. Optimize Sleep QQRT

Focus on the Quantity, Quality, Regularity, and Timing (QQRT) of your sleep, as these are fundamental pillars for optimizing emotional reactivity and overall mental balance.

2. Align Sleep with Chronotype

Match your sleep and wake times to your natural chronotype (your individual 24-hour rhythm) to reduce the risk and symptoms of depression; use the free MEQ questionnaire to determine your chronotype.

3. Maximize Morning & Daytime Light

Get as much light as possible, especially sunlight, in your eyes in the morning and throughout the day to reduce mental health challenges like depression, anxiety, and PTSD.

4. Prioritize Nighttime Darkness

Ensure you are in very dim or dark environments at night to reduce symptoms of depression, anxiety, and PTSD, even if daylight exposure during the day was suboptimal.

5. Avoid Evening “Junk Light”

Treat artificial light from screens and other sources at night as ‘junk light’ or ’empty photons’ and avoid it to protect your sleep quality and overall well-being.

6. Extend Morning Sleep for REM

To enhance rapid eye movement (REM) sleep, sleep an extra 15-20 minutes later into the morning, as the last quarter of the night is the most REM sleep-rich phase.

7. Eliminate Alcohol & THC for REM

Do not consume alcohol or THC, as both are potent substances that will remove or obliterate your rapid eye movement (REM) sleep.

8. Improve Sleep Quality for Anxiety

Prioritize sleep quality, particularly deep non-REM sleep, as it is a strong predictor of anxiety dissipation and re-engages the frontal lobe for anxiety reduction.

9. Maintain Sleep Regularity

Establish and maintain a regular sleep schedule (going to bed and waking up at the same time daily) to ensure stable, continuous sleep, which is crucial for deep non-REM sleep quality and reducing anxiety.

10. Exercise for Deep Sleep

Engage in physical activity to improve the electrical quality of your deep non-REM sleep, which is beneficial for managing anxiety.

11. Cool Bedroom for Deep Sleep

Keep your bedroom cool to promote an increase in deep non-REM sleep, which aids in anxiety reduction.

12. Warm Bath/Shower Before Bed

Take a warm bath or shower before bed to improve deep non-REM sleep, which helps manage anxiety by promoting cooling of the body core.

13. Limit Evening Alcohol

Reduce excessive alcohol consumption in the evening as it fragments sleep and restricts deep non-REM sleep, potentially increasing anxiety and long-term chronic anxiety.

14. Yoga Nidra for Addiction Recovery

Practice non-sleep deep rest (Yoga Nidra) for 30 minutes to an hour first thing upon waking, especially for individuals in inpatient addiction recovery, to compensate for sleep deprivation and aid sobriety.

15. Yoga Nidra for Sleep Onset

Consider using non-sleep deep rest (Yoga Nidra) at the end of the day to help transition into a liminal state and reduce stress about falling asleep, acting as a bridge between wakefulness and sleep.

16. Prioritize Sleep for Addiction

Prioritize sufficient sleep to resist addiction potential and maintain abstinence during recovery, as sleep deprivation enhances reward circuitry and impulsivity.

17. Monitor Sleep for Suicide Risk

Recognize sleep disruption (short, poor quality, irregular sleep) as a potential biomarker for upcoming suicide risk, preceding suicidal thoughts, attempts, and completion, suggesting a need for increased support and intervention.
