Sleep is important for cognitive restoration and learning. Your brain never stops working.
During sleep, the brain consolidates memories, removes waste products, and repairs cells damaged by stress or pollution. It also helps regulate important hormones and neurotransmitters that are essential for healthy brain function. Getting enough sleep is crucial for maintaining cognitive function, mood stability, and overall brain health.
During sleep, brain cells perform important functions such as consolidating memories, clearing out toxins, and restoring energy levels.
