Research and Real-World Applications

Under the guidance of Dr. Franklin Ly, Calmstone has been evaluated in research and real-world settings to explore how thermal biofeedback may support relaxation, comfort, and overall well-being.

Across studies led by Dr. Ly, participants reported lower anxiety scores during approximately 80% of biofeedback sessions and lower chronic pain scores during approximately 60% of sessions. Improvements in sleep quality were also reported by many participants.

These findings suggest that Calmstone may be a valuable addition to mindfulness, breathing, and relaxation practices. Individual experiences may vary, and Calmstone is intended to support - not replace - professional medical or mental health care.

Understanding Thermal Biofeedback

Calmstone uses thermal biofeedback to help you become more aware of subtle changes happening within your body during relaxation.

Skin temperature can shift in response to changes in blood flow and activity within the autonomic nervous system. During moments of stress, blood vessels in the hands may narrow, causing skin temperature to decrease. As the body begins to relax, blood flow to the hands may increase, allowing skin temperature to gradually rise.

Calmstone detects these temperature changes and translates them into a responsive display of colored LED lights. This real-time visual feedback gives you a simple point of focus while practicing breathing exercises, meditation, mindfulness, or other relaxation techniques.

Over time, observing these patterns may help you better recognize how your body responds during moments of stress and relaxation. Calmstone offers a natural, non-invasive way to build greater mind-body awareness and create a more consistent wellness routine.
