Jha, director of the University of Miami’s Contemplative Neuroscience said “We found that getting as little as 12 minutes of meditation practice a day helped the Marines to keep their attention and working memory — that is, the added ability to pay attention over time — stable.” Our attention is fragile. Jha likens our attention to “a flashlight you can direct to whatever you choose.” “If they practiced less than 12 minutes or not at all, they degraded in their functioning.”
One 15-minute meditation may help people make better choices, according to new research from researchers at INSEAD and The Wharton School. The findings are published in the February issue of Psychological Science, a journal of the Association for Psychological Science.
"Most people have trouble admitting they were wrong when their initial decisions lead to undesirable outcomes," says researcher Andrew Hafenbrack, lead author on the new research and doctoral candidate at INSEAD. "They don't want to feel wasteful or that their initial investment was a loss. Ironically, this kind of thinking often causes people to waste or lose more resources in an attempt to regain their initial investment or try to 'break even.'" Co-author Zoe Kinias said, "First, meditation reduced how much people focused on the past and future, and this psychological shift led to less negative emotion. The reduced negative emotion then facilitated their ability to let go of sunk costs."
Then, in the emotional well-being area, one recent study found that a brief mediation practiced for 25 minutes for three consecutive days diminished meditators’ stress level. Published in the journal Psychoneuroendocrinology, this provides an initial indication that brief meditation training reduces stress reactivity, but also increases cortisol reactivity to social evaluative stress. This seems to indicate that brief meditation training fosters greater active coping efforts, resulting in reduced psychological stress appraisals and greater cortisol reactivity during social evaluative stressors.
Some people think they may not have enough time available in their life to meditate. Of course the studies show many more benefits for daily regular meditation over months but the above studies show that even a beginner, with as little as 12 -15 minutes can gain benefits with meditation.
