Recent scientific research has revealed that humans possess an internal vital capacity known as "Interoception," expanding beyond the traditional five senses. This sense functions to monitor and regulate internal biological signals such as heart rate, respiration, hunger, thirst, and body temperature to maintain homeostatic balance. Researchers emphasized that this mechanism is closely linked to mental health, as an individual's accuracy in perceiving their bodily signals directly influences how they manage psychological stress, anxiety levels, and mood, opening new avenues for developing therapeutic strategies for psychological and behavioral disorders.
