Trauma

Trauma is defined as a moment of perceived helplessness that activates the limbic system. It can stem from a single major wounding event (big T trauma) or a series of smaller, cumulative events (little T traumas).

Trauma Tree Model

This model illustrates trauma with roots (causes) and branches (adaptations). The roots, such as abuse or neglect, are often not visible, while the branches, like codependency or addiction, are the visible coping strategies that develop in response to the trauma.

Implicit vs. Explicit Memories (in Trauma)

Explicit memory refers to the conscious recall of an event, where a person might objectively believe it didn't impact them. Implicit memory, however, refers to unconscious impacts, where the event still affects them through anxiety or other forms of discomfort, even if they don't consciously remember or acknowledge it.

Guilt vs. Shame

Guilt is described as feeling bad about making a mistake or doing something wrong. Shame, conversely, is a deeper feeling of being a mistake or inherently flawed as a person.

CBTI (Cognitive Behavioral Therapy for Insomnia)

CBTI is one of the most effective tools for addressing serious insomnia, focusing on the triangle of thoughts, feelings, and behaviors. It helps individuals develop new coping strategies and behavioral changes to improve sleep quality and overcome insomnia.

Sleep Efficiency

Sleep efficiency is a calculation of the time spent sleeping divided by the total time spent in bed. A target sleep efficiency of around 85% is desirable; lower indicates too much time awake in bed, while higher might suggest not enough time allocated for sleep.

Stimulus Control (for sleep)

This technique limits the bed's use to only two activities: sleep and sex. It means avoiding activities like reading, using phones, or worrying in bed to prevent the brain from associating the bed with wakefulness or stress.

Time in Bed Restriction

A CBTI technique that involves intentionally reducing the total time spent in bed to increase sleep pressure and improve sleep efficiency. It helps consolidate sleep into a shorter, more efficient block rather than spending long periods awake in bed.

Social Jet Lag

This term refers to the disruption of the circadian rhythm caused by inconsistent sleep schedules, particularly when people sleep in significantly later on weekends compared to weekdays. This inconsistency can be detrimental to overall sleep hygiene and circadian alignment.

?
What is the core problem that trauma creates?

The core problem of trauma is that it leads to a disconnected version of a person who relies on maladaptive strategies to replace genuine connection with something else, such as work, perfectionism, or substances.

?
What are the five 'roots' or causes of trauma?

The five roots of trauma are abuse (physical, emotional, sexual, religious), abandonment (physical or emotional), neglect, enmeshment (boundary violations/emotional incest), and tragic events (war, violent events).

?
What are the four 'branches' or adaptations that stem from trauma?

The four branches, or adaptations, are codependency (an outer reach for inner security), addictive patterns (substances, work, process obsession), attachment issues (anxious, avoidant, disorganized), and other maladaptive strategies.

?
How effective is Cognitive Behavioral Therapy for Insomnia (CBTI)?

CBTI is highly effective, with 50% to 60% of people achieving complete remission from insomnia and 70% showing significant improvement.

?
What factors contribute to insomnia, and which does CBTI address?

Insomnia is influenced by predisposing factors (genetics, past experiences), precipitating factors (life crises), and perpetuating factors (coping strategies). CBTI uniquely focuses on addressing the perpetuating factors, independent of the initial causes.

?
Why should individuals struggling with insomnia avoid using sleep trackers?

Sleep trackers are generally not recommended for those with insomnia because they can create a brutal cycle of anxiety and overthinking about sleep data, which can exacerbate the problem rather than help fix it.

?
What is the ideal wake-up time strategy for improving sleep?

Maintaining a consistent wake-up time, even on weekends, is crucial for standardizing the circadian rhythm and building sleep pressure, which then helps regulate bedtime more naturally.

1. Understand Trauma’s Core Definition

Recognize trauma as a moment of perceived helplessness activating the limbic system, whether from a major event (“big T”) or a series of smaller ones (“little T”), leading to a disconnected self using maladaptive strategies. This foundational understanding helps identify underlying issues beyond surface-level events.

2. Focus on Adaptation, Not Event

Shift your focus from “what happened” in trauma to “how did I adapt,” as these adaptations, while initially protective, often become maladaptive later in life, causing disconnection and unhealthy coping mechanisms. This reframing is crucial for understanding current behaviors and initiating change.

3. Address Trauma Proactively

Accept that trauma must be dealt with, as “you’re either going to deal with it or it’s going to deal with you,” meaning unresolved issues cannot be buried indefinitely and will inevitably resurface. This encourages proactive engagement with healing rather than avoidance.

4. Recognize Maladaptive Strategies

Identify coping mechanisms that replace genuine connection, which can include obvious “bad” behaviors like substance abuse or gambling, but also seemingly “good” ones like workaholism or perfectionism. Noticing these behaviors is the essential first step towards healthier alternatives.

5. Put Adaptive Child in Backseat

Consciously work to “put the adaptive child out of the driver’s seat and into the back of the car,” meaning to recognize and reduce reliance on childhood coping strategies that no longer serve you as an adult. This allows for more mature and effective responses to life’s challenges.

6. Connect Overreactions to History

When experiencing an emotional overreaction, ask yourself, “What was that really about?” to determine if it’s rooted in a deeper, historical vulnerability, using the saying “if it’s hysterical, it’s historical.” This practice aids in self-reflection and understanding the true cause of intense emotional responses.

7. Understand Trauma Tree Model

Utilize the “trauma tree” model, which illustrates how invisible roots (causes like abuse, abandonment, neglect, enmeshment, tragic events) lead to visible branches (adaptations like codependency, addictive patterns, attachment issues, and other maladaptive strategies). This framework helps visualize and comprehend the complex interplay between past experiences and current behaviors.

8. Accept Unintentional Wounding

Recognize that the “wounding events” (roots) of trauma are often unintentional, not driven by a deliberate intent to harm. This understanding can help individuals avoid minimizing their past impact and facilitate healing by removing the burden of perceived malicious intent.

9. Differentiate Guilt and Shame

Understand the clear distinction between guilt (feeling bad about making a mistake) and shame (feeling bad about being a mistake), as this differentiation is vital for processing emotions related to past actions and self-perception in a healthier way. This clarity supports more effective emotional healing.

10. Practice Distress Tolerance Expansion

Actively practice expanding your “distress tolerance window” by identifying and engaging in activities, such as meditation, that increase the probability of responding thoughtfully instead of reacting impulsively to stressful situations. This builds emotional resilience and self-control.

11. Use ‘I’ Statements

Learn and consistently practice using “I statements” to take ownership of your thoughts, feelings, and actions. This communication technique promotes personal responsibility and clearer expression of internal states, improving interpersonal interactions.

12. Explore Triangle of Vulnerability

Work through the “triangle of vulnerability” (sadness, shame, fear) by being curious about your current position on it and becoming more responsive to your own emotional vocabulary around these core feelings. This deepens self-awareness and facilitates more effective emotional processing.

13. Notice and Address Coping Skills

Pay close attention to your coping skills, especially those that serve as distractions (e.g., eShopping for stress), even if they seem benign, as they can prevent genuine connection and acceptance of current situations. Identifying these helps in replacing them with healthier, more constructive alternatives.

14. Consider Immersive Trauma Therapy

If traditional therapy proves insufficient, consider undergoing “immersive therapy” at a residential program, such as The Bridge to Recovery or PCS, for focused, in-depth work on trauma. This intensive environment can accelerate healing by providing dedicated support and time for processing.

15. Utilize CBTI for Insomnia

Employ Cognitive Behavioral Therapy for Insomnia (CBTI) as a highly effective treatment, with 50-60% of users achieving complete remission and 70% showing improvement. Much of CBTI can be self-implemented, focusing on current coping strategies rather than predisposing or precipitating factors.

16. Understand Insomnia Criteria

Define true insomnia as sleep issues persisting for months, interfering with daily life, and causing significant distress, to avoid over-pathologizing occasional bad nights. This helps in accurately identifying when professional intervention or CBTI is genuinely needed.

17. Implement Strict Sleep Hygiene

Maintain strict sleep hygiene by keeping your bedroom cold (mid-sixties Fahrenheit), as dark as possible (using an eye mask if necessary), and avoiding excessive fluid intake after dinner. Additionally, remove heavy blankets and down comforters to support the body’s natural cooling process essential for deep sleep.

18. Practice Stimulus Control in Bed

Limit bed use strictly to only two activities: sleep and sex, actively avoiding phones, reading, and especially worrying while in bed. This conditions your brain to associate the bed solely with rest and relaxation.

19. Get Out of Bed When Awake

If you are lying awake in bed for 20-30 minutes, particularly if worrying, get out of bed and engage in a low-key, non-activating activity (like reading a trashy magazine or watching a silly sitcom) until you feel sleepy again, then return to bed. This breaks the negative association of the bed with wakefulness and anxiety.

20. Prioritize Fixed Wake-Up Time

Establish and consistently maintain a fixed wake-up time, even on weekends, as this is the most crucial factor for regulating your circadian rhythm and building healthy sleep pressure. Avoiding “social jet lag” helps standardize your sleep schedule and improve overall sleep quality.

21. Implement Time in Bed Restriction

If struggling with insomnia and low sleep efficiency (time sleeping divided by time in bed), consider time in bed restriction by first tracking your typical sleep duration, then adding a 30-minute buffer to set a target time in bed. This strategy aims to increase sleep efficiency by reducing the amount of time spent awake in bed.

22. Avoid Sleep Trackers if Insomniac

If you are struggling with insomnia, put away or stop using sleep trackers, as the data can exacerbate anxiety and create a “brutal cycle” of worry about sleep metrics. Focus instead on implementing behavioral changes rather than obsessing over data.

23. Schedule Dedicated Worry Time

Combat nighttime rumination by scheduling a specific “worry time” during the day (e.g., 20 minutes) to intentionally write down all your concerns and anxieties. This practice helps prevent these thoughts from intruding on your sleep time.

24. Track Degree of Belief for Worries

Practice “tracking the degree of belief” by asking yourself how much you truly believe your worries are true, especially when they seem more certain at night. This technique helps to objectively evaluate and often diminish the intensity of nighttime anxieties.

25. Address Underlying Sleep Pathologies

Before engaging in CBTI or other sleep improvement strategies, ensure any underlying medical sleep pathologies, such as restless leg syndrome or sleep apnea, are properly diagnosed and addressed. This ensures that behavioral and cognitive interventions are targeting the correct issues.

26. Experiment with Less Effective Aids

While not primary solutions, experiment with supplementary tactics like blocking blue light (e.g., using red light glasses), optimizing caffeine timing, and trying certain medications or supplements to see if they offer any personal benefit for sleep. These are secondary to core CBTI principles and sleep hygiene.

If it's hysterical, it's historical.

Jeff English

You're either going to deal with it or it's going to deal with you. These things cannot be buried. They're going to always, like a whack-a-mole thing, always show up at some point. And you can't play whack-a-mole indefinitely.

Peter Attia

Being disconnected versus being connected is all the difference in living.

Peter Attia

I've never met a person who's addressed their negative adaptations and come out on the other side and said, I wish I didn't do that.

Peter Attia

Anything with duvet in it should be banned.

Ashley Mason

Stimulus Control for Insomnia

Ashley Mason
  1. Limit the bed to only two activities: sleep and sex.
  2. If you are lying in bed awake, especially worrying, get out of bed.
  3. Go to another room and engage in a low-key activity for 20 to 30 minutes (e.g., read a trashy magazine, watch a silly sitcom) that is not activating.
  4. Return to bed only when you feel sleepy.

Schedule Worry Time (Cognitive Technique for Insomnia)

Ashley Mason
  1. Schedule a specific time on your calendar, typically 20 minutes a day, for worrying.
  2. During this scheduled time, intentionally write down all the things you are worried about.
  3. Avoid processing these worries at night when you are in bed.
