Meditation involves focusing on your breath or a specific target, which requires high attentional load and prefrontal cortical activity. Daily meditation for at least eight weeks can enhance attention ability, learning, and memory. However, it may inhibit sleep if done too late in the day. Non-sleep deep rest, such as Yoga Nidra, can put people into a state of deep relaxation with low attention and prefrontal cortex activation. There are different types of meditation, including focused attention and open observer meditation, which can enhance focus and creativity.
