孤独会重塑大脑，让人越来越不愿意与他人接触

Group 1 - The Neumayer III station in Antarctica serves as a research site for studying the effects of social isolation and environmental monotony on the brain [2][3] - A study involving eight explorers showed that prolonged social isolation led to a reduction in the volume of the prefrontal cortex and lower levels of brain-derived neurotrophic factor (BDNF) [2][3] - The effects of loneliness on the brain can lead to significant health risks, including increased chances of hypertension, stroke, heart disease, type 2 diabetes, and dementia [6][12] Group 2 - Research indicates that loneliness alters cognitive processes, making individuals more sensitive to negative social signals and less trusting of others [8][12] - The default network in the brain, which is activated during social thinking, shows stronger connections in individuals experiencing long-term loneliness [9][11] - Studies suggest that loneliness may be an evolutionary adaptation, similar to hunger, driving individuals to seek social connections [14][15] Group 3 - Cognitive therapy has been shown to effectively reduce feelings of loneliness by helping individuals recognize behaviors that hinder social connections [16] - Interventions aimed at fostering trust and synchrony in social interactions may provide pathways to alleviate loneliness [16][17] - Recent experiments with psychedelics like psilocybin have indicated potential for reducing feelings of social exclusion and altering brain activity related to painful social experiences [17]
