Q: What happens in our brains when we engage in intense mental activity?

A: When we use our brains intensely– whether it be through critical thinking, problem-solving, or decision-making – we activate the prefrontal cortex region of our brain. This area is responsible for executive functions such as attention control and working memory.

Q: Why does this result in a feeling of fatigue?

A: The prefrontal cortex has limited resources when it comes to glucose and oxygen consumption. Engaging heavily in complex cognitive activities uses up these limited resources very quickly. Therefore, once they are depleted from overuse, they need time to replenish which results in feelings of exhaustion.

Q: How long can the effects of cognitive fatigue last?

A: It varies depending on each individual case and situation but generally speaking resting period including deep relaxation methods help boost energy recovery rapidly without any side-effects.

Q: Is there anything we can do to prevent cognitive fatigue from setting in too soon?

A : Yes! There are plenty of ways to train your mind and improve its endurance by regular practice or even using supplements specially designed for better performance and concentration

Q: What about other lifestyle factors like sleep and nutrition? Do they have an impact on cognitive fatigue?

A : Diet and quality of restful or deep sleep can play a huge role in maintaining optimal mental sharpness. Poor diet lacks key ingredients needed for our brains survival mostly omega-3 acids found primarliy in fish oil supplements , vitamins B12/6 specifically related with nerve connectivity development whilst research shows that lack of good night’s rest impairs focus, memory…
