This study focuses on meditation’s ability to prevent neurodegenerative diseases such as Alzheimer’s. As an aging population decreasing cognitive function has posed increasing challenges. One of the big contributors to these types of degeneration is stress: defined here as any state that disrupts the body’s homeostasis. Here we see significant evidence that practicing meditation, such as Kirtan Kriya meditation for only 12 minutes a day, improves memory in those with cognitive decline, mild cognitive impairment, and highly stressed caregivers. It also improves sleep quality, lessens depression, and decreases anxiety. On a biological level, it helps upregulate immune system genes and improves insulin and glucose regulation, and increases telomerase by 43%.
