Based on current scientific studies, Reiki has been shown to offer a range of potential benefits—particularly in supporting emotional and psychological well-being. Meta-analyses and clinical trials suggest that Reiki may help reduce symptoms of stress, anxiety, and depression, with several placebo-controlled studies reporting measurable improvements in mood and relaxation among participants. Research also indicates that Reiki sessions can lead to lower heart rate, blood pressure, and subjective stress levels, reflecting a general calming effect on the nervous system. These effects are often attributed to the deep relaxation and mindful attention that occur during a Reiki session, which may help the body shift from a stress response into a state of balance and rest.

Emerging evidence also suggests Reiki can enhance quality of life and reduce pain for some individuals, particularly when sessions are held regularly or last longer than 60 minutes. While the mechanisms behind Reiki are not yet fully understood and more rigorous studies are needed, the growing body of research supports its use as a complementary wellness practice. Rather than replacing medical care, Reiki may serve as a supportive tool for emotional release, mental clarity, and inner harmony—helping people feel more centered, resilient, and connected to their natural state of well-being.
