Yoga nidra might be a path to better sleep and improved memory

Practicing yoga nidra—a kind of mindfulness training—might improve sleep, cognition, learning, and memory, even in novices, according to a pilot study published in the open-access journal PLOS ONE on December 13 by Karuna Datta of the Armed Forces Medical College in India, and colleagues. After a two-week intervention with a cohort of novice practitioners, the researchers found that the percentage of delta-waves in deep sleep increased and that all tested cognitive abilities improved.
