Essentials: Understand and Use Dreams to Learn and Forget

Dec 12, 2024 38m 49s 14 insights
In this Huberman Lab Essentials episode, I explain the important role that sleep and dreams have in learning, regulating emotions, and recovering from trauma. I discuss how dreams during rapid eye movement (REM) sleep contribute to emotional learning and the processing of traumatic experiences. I also discuss the similarities of REM dreams to clinical treatments like ketamine and EMDR therapy. I explain how non-REM dreams function differently to support other types of learning. Additionally, I describe science-backed strategies to optimize both types of sleep for improved learning, mood and emotional regulation. Huberman Lab Essentials are short episodes (approximately 30 minutes) focused on essential science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, and our full-length episodes will still be released every Monday. Read the full show notes for this episode at hubermanlab.com.
Actionable Insights

1. Prioritize Sleep Consistency

Aim for consistent sleep duration each night (e.g., 6-6.5 hours consistently) rather than varying widely, as consistency is crucial for learning and emotional regulation.

2. Actively Manage Sleep During Disruptions

Actively manage your sleep schedule and environment during disruptive life events (travel, stress, schedule changes) to maintain sleep quality, as sleep is crucial for emotional unlearning and overall well-being.

3. Ensure Adequate REM Sleep

Prioritize getting sufficient REM sleep to prevent emotional irritability, catastrophizing, and to facilitate the unlearning of emotional responses.

4. Increase Slow-Wave Sleep with Resistance Exercise

Incorporate resistance exercise into your routine (not necessarily close to bedtime) to increase the percentage of slow-wave sleep, which is important for motor learning and the acquisition of fine, detailed information.

5. Avoid Alcohol/Marijuana for Sleep Quality

Avoid alcohol, marijuana (THC), and similar substances if you aim for optimal sleep patterns, depth, and the natural sequencing of slow-wave and REM sleep.

6. Use NSDR for Mid-Night Waking

If you wake up around 3-4 AM, use a non-sleep deep rest (NSDR) protocol to relax your body and brain, helping you fall back asleep and get more REM sleep.

7. Optimize Sleep Environment Temperature

Optimize your sleeping environment’s temperature to allow your body temperature to drop by 1-3 degrees, which is essential for falling and staying deeply asleep.

8. Practice Lateral Eye Movements for Stress

Perform lateral eye movements (sweeping eyes from side to side with eyes open) to suppress amygdala activity and reduce fear, stress, and anxiety, especially when recounting troubling experiences.

9. Consider EMDR for Specific Trauma

For single-event trauma, consider EMDR (Eye Movement Desensitization Reprocessing) therapy with a certified professional, as it uses lateral eye movements to suppress amygdala activity and uncouple emotional load from the experience.

10. Consider Ketamine Therapy for Trauma

In a clinical setting, ketamine can be used to prevent intense emotions from attaching to traumatic experiences, but this requires physician consultation due to ethical implications and specific use cases.

11. Limit Fluids Before Bed

Limit fluid intake right before bed to avoid waking up with a full bladder, which can disrupt sleep and reduce the amount of REM sleep obtained.

12. Exercise Caution with Serotonin Supplements

Exercise caution with tryptophan or 5-HTP supplements, as they are serotonin precursors and may disrupt the natural timing and sequencing of REM and slow-wave sleep.

13. Supplement with AG1 for Foundational Nutrition

Consider taking AG1 daily to bolster energy, immune system, and gut microbiome, especially if you find it difficult to obtain sufficient micronutrients from food alone.

14. Utilize Red Light Therapy

Consider using red light and near-infrared light therapy devices to potentially improve muscle recovery, skin health, wound healing, reduce acne, pain, inflammation, and enhance mitochondrial and visual function.
