Some facts I learned today that may be helpful for all
Feel free to share with those who would benefit from this knowledge š¤
š¹ Why Interpreting Feels Exhausting
1. Cognitive Overload
ā¢ Youāre listening, processing, and producing speech in two languages at once.
ā¢ Thatās triple tasking ā more demanding on working memory than almost any other professional task.
ā¢ This high cognitive load burns through glucose and oxygen in the brain, which can make you feel physically depleted.
2. Physiological Stress Response
ā¢ Heart rate and blood pressure rise slightly during interpreting (measurable in studies).
ā¢ Cortisol (the stress hormone) goes up in prolonged or high-stakes settings (like court).
ā¢ Your body treats it almost like a performance or exam environment.
3. Muscle Tension & Posture
ā¢ Sitting still, often in tense body positions, creates static strain in the neck, shoulders, and back.
ā¢ Micro-movements of your diaphragm, intercostals, and face muscles are constant ā which is why many interpreters feel āwrung outā after a long day.
4. Caloric Burn
ā¢ You do burn slightly more calories than passive sitting.
ā¢ Brain work itself is energy-hungry: your brain is ~2% of body weight but uses ~20% of your energy, and simultaneous interpreting spikes that usage.
ā¢ But the fatigue is more from cognitive energy drain than massive calorie burn.

š¹ Health Benefits of Interpreting (when paced well)
ā¢ Brain health: Itās like daily āmental CrossFit,ā shown to strengthen executive function and delay cognitive decline.
ā¢ Neuroplasticity: Regular bilingual switching builds stronger neural networks for attention, memory, and problem-solving.
ā¢ Stress resilience: Over time, interpreters get better at rapid recovery from high-pressure tasks.
ā¢ Social/Emotional: Constant communication keeps emotional intelligence sharp.

š¹ What Youāre Feeling
Your exhaustion isnāt āall in your headā ā itās very real. Itās not just burning calories; itās draining neurotransmitters, stressing muscles, and spiking stress hormones. Thatās why you often feel like youāve run a marathon by the end of trial or conference days.
š Which is why recovery (sleep, hydration, nutrition, bodywork like acupuncture, even little courtroom stretches) isnāt optional ā itās part of the profession.
