Recent research from Harvard Medical School and the National Institute of Mental Health and Neuro Sciences in India has highlighted measurable neurological changes that occur during meditation, even for individuals new to the practice. The findings, published in the journal *Mindfulness* in March 2026, indicate that significant calming effects in the brain typically manifest within the first two to three minutes of meditation, with peak relaxation occurring around seven minutes.

Meditation is known to trigger both physiological and neurological responses, including decreased heart rate and blood pressure as well as a reduction of the stress hormone cortisol. Neurologically, the amygdala—responsible for processing fear and emotions—exhibits reduced activity, while the prefrontal cortex, associated with rational thinking and focus, shows increased activation. These changes contribute to reports of enhanced calmness and concentration among practitioners.

Dr. Balachundhar Subramaniam, professor of anesthesiology at Harvard Medical School and director of the Sadhguru Center for a Conscious Planet at Beth Israel Deaconess Medical Center, explained that meditation helps individuals observe thoughts without becoming entangled in them, creating a degree of mental detachment. According to Subramaniam, meditation can alleviate symptoms of anxiety and depression, improve sleep, strengthen interpersonal relationships, and enhance workplace engagement. His research also suggests that regular meditation is linked to slower brain aging by approximately six years.

Three broad categories of meditation are frequently identified: focused-attention meditation, which directs concentration on a single object such as breathing; open-awareness meditation, which involves non-reactive observation of thoughts and sensations; and loving-kindness meditation, which cultivates compassion toward oneself and others.

Despite the known benefits, many people encounter challenges when beginning meditation, including uncertainty about methods and difficulty quieting the mind. Subramaniam counters these concerns by emphasizing the simplicity and accessibility of meditation, recommending focus on the breath as a constant, readily available anchor.

In a practical demonstration, a journalist with no prior meditation experience participated in a 15-minute guided session involving a recording of Indian yogi Sadhguru repeating the phrases “I am not the body. I am not even the mind,” coordinated with controlled breathing. Initial difficulties with matching the pace gave way to a state the researcher described as “time dilation,” akin to moments of heightened awareness experienced by athletes during critical performance periods. During this state, the participant reported a blank mind and a sensation of slowed time.

Brain scans conducted during the session showed sustained alpha wave activity linked to alertness for the first minute, followed by a significant increase in slower-frequency theta waves associated with deep inner calm, peaking between seven and eight minutes. Notably, the participant’s baseline brain activity shifted after the meditation, with a 13% increase in theta wave activation persisting beyond the session.

These findings reinforce existing evidence that meditation fosters a range of mental and physical health benefits, even for novices, and underscore the potential cumulative effects of regular practice.
