蓝色思维自然沉浸：泰国孤独潜水员剪影

unrecognisable scuba diver drifts faintly through open blue water beyond a red gorgonian sea fan coral, creating a still, contemplative underwater scene associated with nature immersion and stress relief. Descending into calm blue water is widely linked to the mammalian dive reflex, a physiological shift toward parasympathetic rest that underpins blue mind theory and underwater mindfulness. 4K, wide angle, vertical medium shot, scuba diver POV.
