Relieving attention fatigue: Recharge your mental batteries productively

To concentrate on a task you need to block out distractions. In fact that’s what it means to concentrate — to inhibit other instinctual inclinations. Once that blocking function gets worn down by fatigue then you are more likely to act on impulse, to run away if something challenges you too much, to take unnecessary risks, to become irritable, and to get distracted from your task by things that are more engaging but less challenging, such as video games, television programmes, or random images on the Internet. These are symptoms of attention fatigue.
