Sleep

Sleep and rest are crucial good brain health. During sleep, the brain undergoes maintenance processes, such as consolidating perceptual learning and memories, repairing and regenerating tissues, and flushing out toxins. First, the brain processes and stores information that we have acquired during the day, wiring circuits to make the interpretation based on our experience and easily retrieve stored items for use later on. Second, the brain produces various growth factors that promote the growth and repair of brain cells, and helps to strengthen neural connections. Finally, sleep is also important for regulating our mood and emotional wellbeing. People who are sleep-deprived are more likely to experience irritability, anxiety, and depression; cognitive function, mood, and overall health suffers.
