Peter’s pred
Mindsip insights from this episode:
Recognize trauma as perceived helplessness to understand its impact
Trauma is defined not by the event itself, but as a moment of perceived helplessness that activates the limbic system, which can result from a single major event or a series of smaller ones.
Schedule worry time to combat insomnia
A cognitive technique to combat insomnia is to schedule a specific 'worry time' during the day to write down all your concerns, reducing the need to ruminate on them at night.
Recognize good habits as potential trauma responses
Maladaptive strategies resulting from trauma are not just 'bad' things like drugs, but can also be perceived as 'good' things like workaholism or perfectionism.
Recognize historical roots of emotional overreactions
The saying 'if it's hysterical, it's historical' suggests that emotional overreactions in the present are often triggered by unresolved vulnerabilities from the past.
Choose 'The Bridge to Recovery' and 'PCS Psychological Counseling Services' for immersive trauma therapy
For intensive, immersive trauma therapy, Peter Attia personally recommends 'The Bridge to Recovery' and 'PCS Psychological Counseling Services'.
Ban duvets to enhance sleep quality
To improve sleep quality, you should avoid anything that traps too much heat, with sleep expert Ashley Mason specifically recommending that anything with a duvet should be banned.
Reevaluate sleep efficiency; aim for adequate time in bed
A sleep efficiency of 95% is actually too high and almost certainly means you are not giving yourself enough time in bed to sleep.
Stop using sleep tracker to break insomnia cycle
If you are struggling with insomnia, one of the first and most important steps is to stop using your sleep tracker, as it can create a brutal cycle of anxiety.
