THIS IS WHY OVERTRAINING & OVERSTRESS IS BAD. MENTAL PERFORMANCE ; CRTICAL THOUGHT; & HIGH LEVEL & HIGHEST LEVEL DECISION MAKING MEANS DO NOT OVERSTRESS. [& KEEP NUTRITION HIGH & WITH VERY LOW CORTISOL]
The best way to control the mind is to exhaust the body is a phrase often repeated in psychology, military training, and behavioral science. It reflects a real and well studied connection between physical fatigue and mental control. When the body is pushed into extreme tiredness, the brain shifts into energy saving mode. Cognitive functions like critical thinking, emotional regulation, and decision making become weaker. This is not a theory but a documented psychological response.
Research in psychology shows that prolonged physical exhaustion increases cortisol, the stress hormone. Elevated cortisol reduces activity in the prefrontal cortex, the part of the brain responsible for logic, impulse control, and independent thinking. At the same time, the brain relies more on automatic behaviors and emotional reactions. This is why exhausted people are more likely to comply, follow instructions, or accept ideas without questioning them.
Sleep deprivation studies also support this effect. Lack of rest reduces attention span, weakens memory, and lowers resistance to persuasion. In high pressure environments like intense work schedules, extreme fitness routines, or constant stress, mental resilience slowly breaks down. The mind becomes easier to influence because it is focused on survival, not reflection.
Psychology also shows the opposite is true. Physical recovery, proper rest, and balanced movement strengthen mental clarity and emotional stability. A rested body supports a sharper mind. Understanding this connection helps people protect their mental autonomy and recognize when exhaustion is being used as a control mechanism.
