Sleep is an essential component of brain health, supporting cognitive function, memory consolidation, and emotional control. During sleep, the brain performs necessary activities such as detoxification, which removes toxic waste materials generated throughout the day. This cleansing is essential for preventing neurodegenerative disorders and promoting general brain health.

Adequate sleep is required for memory consolidation, which involves the brain processing and integrating new information obtained during the day. According to research, both REM (Rapid Eye Movement) and non-REM sleep periods are necessary for various forms of memory, such as declarative and procedural memory. A lack of proper sleep can impede these processes, making it difficult to learn and retain new knowledge.

Chronic sleep deprivation has been associated to a variety of cognitive deficits, including lower attention, poor decision-making, and problem-solving abilities. It also raises the possibility of acquiring mental health issues including sadness and anxiety. Prioritizing good sleep hygiene, such as sticking to a regular sleep schedule and providing a comfortable sleep environment, is critical for preserving brain health and cognitive function.
