Ever wondered why we feel exhausted after work? Does your post-work schedule also encompass hours of endless scrolling? Do you also feel like lying on your couch and doing nothing? If yes, then you aren't alone. Thousands of people across the world feel the same. Many of them want to play with their pets, solve a puzzle or paint a portrait; however, as soon as they return from office, they feel a drain of energy. As per experts, this end-of-day exhaustion is a specific kind of tiredness tied to the mental and emotional strain of work, not necessarily the tasks themselves, but the constant switching between demands, decisions and yes, meetings. Health experts describe it as something called cognitive fatigue. Let's Understand What Exactly Is Cognitive FatigueCognitive fatigue is the deterioration in the ability to effectively and focus effectively. It is primarily caused by prolonged mental work. Many workers might spend their days completing a lot of tasks that aren't urgent or necessary, but do create lots of vacuums of time and mental energy to respond to. Cognitive fatigue occurs when we make many more micro decisions in the day than we need to, and there are so many different touch points that grab our attention in an office. These could be noise, colleagues, phones, Slack or meetings.Also, not moving our bodies can be more draining than moving them throughout the day, as our bodies are meant to move naturally. Therefore, people with sedentary jobs or back-to-back meetings with little time in between will be the ones most affected by this. According to psychologists, cognitive fatigue may have multiple symptoms. Some indicators include the following:Difficulty concentrating and staying focused when performing tasks, making decisions, and following conversationsA longer time is necessary to complete mental tasks that someone typically performs quicklyManifestation of forgetfulness and difficulty recalling information or eventsReduced ability to solve complex problems or think criticallyLimited creativityMore frequent mistakes
