The fluttering feeling when under stress is both neurological and physical
The physical sensation of stress, such as a fluttering feeling, arises from both neurological signaling and bodily autonomic activation.
The retrieved papers consistently demonstrate that psychological stress engages both central and peripheral nervous systems, alongside visceral bodily responses like autonomic and sympathetic activation. Therefore, the claim that the feeling under stress is both neurological and physical is well-supported by modern psychophysiology and neuroscience literature.
