The National Institute of Neurological Disorders and Stroke's article, "Brain Basics: Understanding sleep," emphasizes sleep's critical role in brain health and cognitive function. It explains that sleep is essential for forming and maintaining neural pathways, which are vital for learning and memory consolidation. During sleep, the brain remains active, performing functions like toxin removal and energy conservation. Chronic sleep deprivation is linked to health issues such as high blood pressure, cardiovascular disease, diabetes, depression, and obesity. To enhance brain health, the article recommends maintaining a regular sleep schedule, creating a comfortable sleep environment, and avoiding stimulants like caffeine before bedtime. These practices support the brain's restorative processes, thereby improving cognitive performance. The information is sourced from a reputable institution, providing a credible basis for these recommendations.
