Can meditation or brain 'cooling' actually cause a personality reset?

[jennifer_bloom]

I have been cooling the right mid point of my brain through meditation for years and what I notice is the brain cooling seems to be resetting many aspects of my personality, with each cooling, my hobbies and interests change, and so do my inhibitions and personality traits.

I felt this was a really interesting question but I didn't have an answer so I asked AI:

Short answer: no, not a true “reset” like wiping a hard drive—but yes, it can meaningfully change how you think, feel, and behave over time, sometimes enough that it feels like a new personality.

Let’s unpack that without the fluff.

🧠 What meditation actually does to the brain
Meditation (and related “cooling” practices like breathwork, sensory withdrawal, etc.) affects a few key systems:

Reduces activity in the default mode network (DMN)
→ This is the “self-talk / rumination” network. Less activity = less overthinking, less ego narrative.
Strengthens prefrontal control
→ Better emotional regulation, more deliberate responses instead of reactive ones.
Calms the limbic system (especially the amygdala)
→ Lower baseline anxiety, less emotional volatility.
Shifts neurochemistry
→ Changes in serotonin, dopamine, GABA → mood, motivation, and calmness shift.

🔄 Why it can feel like a “personality reset”
If your personality is partly built on:

habits of thought
emotional reactions
stress patterns
identity stories (“I’m an anxious person”, “I’m reactive”, etc.)
…then meditation can weaken those patterns.

So what happens?

You react less → people see you differently
You think differently → your decisions change
You feel different → your preferences shift
That looks like a new personality from the outside.

❗ But here’s the important boundary
Meditation does not:

erase your core temperament (introversion/extroversion, baseline traits)
delete memories or identity
instantly transform you
Think of it more like:

“Rewriting the operating system settings” rather than replacing the hardware

🧊 About “brain cooling”
If you mean things like:

deep breathing
cold exposure
calming techniques
These mostly:

reduce nervous system arousal (sympathetic → parasympathetic)
improve clarity and emotional control
They support change, but don’t independently “reset” personality either.

⚠️ One edge case worth mentioning
In very intense or prolonged meditation (retreats, extreme practices), some people report:

loss of sense of self
detachment
identity shifts
This is sometimes called “ego dissolution”.

It can be:

positive (clarity, peace)
or destabilizing (confusion, dissociation)
So intensity matters.

🧭 Bottom line
No hard reset
But real, measurable personality change over time
Especially in:emotional stability
reactivity
self-perception

Ty for the MHO 😊

I guess some forms of meditation can actually cause that.
