How to turn off the prefrontal cortex for creativity?

Are there healthy and non-substance-involving ways to turn off the prefrontal cortex, especially in terms of overthinking and "second guessing" one's ideas in a creative and very isolated and focused work endeavor (writing music e.g.)? As you mentioned on the recent creativity podcast episode, cannabis, alcohol or similar substances can have that effect, but can i also do that without substances, or at least make it easier? The only thing that comes to my mind is sleep deprivation, although i would prefer to be on a consistent sleep schedule, if possible. Thank you for considering my question!

Grieving Multiple Events Consecutively

What is the best process for overcoming grief when you have been through multiple adversities consecutively without having enough time in between to process and grieve each event the way I would have liked to? I lost my grandmother, and shortly after that my brother passed away suddenly. Then, shortly after that, my long term boyfriend broke up with me. I’m struggling to process each one because they all happened so close together.

Night shift alternative to morning sun viewing?

I'm night shift 10pm-2am and thanks to yours and Matt Walker's info don't try to change on my 1-2 days off. I get to bed between 5 and 8am, try to get 8 hours sleep also thanks to podcasts, so get up 2pm-ish Any options to replace morning sunlight?

Cold weather vs cold immersion?

Does cold (Michigan) northern weather have similar results to cold immersion therapy? I have a horse farm in Michigan and do chores twice a day, about 15 minutes to an hour each time. As we're getting further into winter I've adapted so I'm comfortable in way less winter clothing than most people are wearing. For example, silk underalls, lined carhartt jeans, carhartt duck vest long sleeve work shirt and denim work shirt over will keep me comfortable into 20's, no jacket or sweatshirt. Although always warm head covering and warm boots, have adequate gloves handy but not wearing all the time. Does being outside in the cold somewhat under-dressed have similar benefits to cold immersion therapy?
