This research investigated the impact of heat massage therapy on various aspects of mental health in adults.A total of 20 adults (10 males and 10 females) aged 25 to 40 years, residing in Rudrapur, Uttarakhand were selected using purposive sampling technique. The tool used were the Mental Health Inventory, designed by Dr. Jagdish and Srivastava (1983) to measure the mental health and the Ceragem V3 thermal device was used for heat massage therapy. In the result notable enhancements were noted after the application of intervention, including lower levels of anxiety, depression, and stress, as well as improved mood and overall well-being. Participants also reported higher self-esteem, self-worth, and satisfaction with their bodies. Furthermore, the therapy fostered better perceptions of reality, personality integration, autonomy, and mastery of the environment. Nevertheless, it did not significantly influence group-oriented attitudes. These results indicate that heat massage therapy is a valuable complementary method for improving mental health, emotional regulation, and self-awareness. Additional studies are needed to examine its wider therapeutic possibilities for mental well-being.
