TM practice significantly reduces the level of stress-related hormones including cortisol, which affects a large number of areas in life, particularly our quality of sleep. Practicing the TM technique also results in the increase of serotonin, the neurotransmitter that plays a key role in regulating mood and sleep-wake cycles. Healthy levels of serotonin promote restful sleep, which enhances overall well-being and resilience to illnesses. This improvement in sleep quality not only helps combat fatigue but also supports better emotional regulation, leading to a more stable mood throughout the day.

A field study compared five years of medical utilization of 2,000 Blue Cross Blue Shield members who practiced the TM technique, compared to a normative data set of approximately 600,000 members of the same insurance carrier. The benefits, deductibles, coinsurance terms, and distribution by gender of the TM practice group were very similar to the norm. Yet, the TM practice group had lower medical utilization rates in all categories. Hospitalization inpatient days were down by 50% vs the norm for children and young adults, and 69% fewer for adults aged 40+. Outpatient visits per 1000 for the same age categories were, respectively, 46.8%, 54.7%, and 73.7% fewer.
