According to an article by Neurohacker, performing just one minute of squats can effectively combat brain fatigue, especially for those who work at a desk. This evidence-backed method is a reminder of the powerful link between mind and body - in this case, physical exertion and cognitive function.
A sedentary lifestyle, often a byproduct of desk jobs, has been linked with a decline in cognitive performance and an increased risk of cognitive degeneration. Sitting for extended periods is a significant contributor to sedentary behavior and is known to negatively affect cognitive functions, specifically executive functions. Executive functions are the cognitive processes fundamental to purposeful behavior, encompassing high-level cognitive skills like working memory, planning, reasoning, problem-solving, emotion regulation, inhibitory control (the capability to suppress thoughts, actions, or feelings), and cognitive flexibility (the aptitude to switch attention between tasks, strategies, stimulus attributes, etc).
A simple strategy like an intermittent half-squat routine is easy to put into practice and could be especially beneficial in environments where exercise resources and time are scarce, such as in the office. This straightforward approach can help to not only ward off a decline but also enhance executive function during prolonged periods of sitting, potentially by sustaining sufficient blood flow to the brain.
