I going to suggest something about my thoughts about stress and its effects on the human mind and body
Please feel free to add to disagree as you like
My starting point is that, the human body is very good at looking after its own immediate needs and will do so regardless of the long term effects.
Also that the mind will cause the body to react in certain circumstances
I particularly want to consider stress, which I believe can create the fight or flight response.
Now bearing in mind my first statement, when stress occurs it will set up a number of conditions within both the body and mind all based around its immediate needs.
Firstly the Physical condition of the body is raised to allow immediate action (run or fight etc)
So there will be an increased heart rate and the blood pressure and blood vessel capacity, additionally the creation of adrenalin and increase awareness (senses) and reflexes.
However the body will also turn off, all non immediate bodily process such as libido, complicated digestion processes, long term memory, higher level cognitive thought processing, complex immune systems etc and probably many more I am not aware of
And in addition switch on short term drivers such as need for sugar rich foods stuffs, reduce the need for deep restful sleep for shallow disturbed sleep patterns in order to maintain the high alert status
Now the status can and was only ever intended to be held for short periods of time, (just to get you out of the sh1t) but the down side is that a prolong stress situation will result in great fatigue on both body and mind.
At which point the body will go into a different mode of self protection, by going into an enforce shut down state, where total in-action will prevail.
This is a point of conflict between the need to able to respond to the high alert stress situation and the need to rest, the resulting condition is the inability to deal with the situation effectively whilst your body is going though all sorts of contortions and disturbance try to match its differing needs.
I believe this state is probably one of the most unhelpful and therefore should be avoided if poss.
Therefore I am suggesting that as part of your prepping plans you might wish to include, the creation of a place and time where you will be able to be calm and relaxed by retreating from any high stress circumstances / situations.
In this way you may be more able to overcome and be more successful in dealing with what ever follows.
happy prepping
