Attention fatigue refers to the mental exhaustion that occurs when an individual is required to focus for extended periods. This condition can arise from constant distractions, multitasking, or prolonged engagement with demanding tasks. As a result, the ability to concentrate diminishes, leading to decreased productivity and increased errors. This phenomenon is particularly relevant in today's digital age, where constant notifications from devices and social media can overwhelm the brain. Strategies to combat attention fatigue include taking regular breaks, practicing mindfulness, and limiting exposure to distractions, which can help restore focus and improve overall cognitive function.
