Months trapped together in Antarctic isolation reveal a risk few long missions can afford to ignore

Key Points:

• A University of Zurich-led study on a ten-month Antarctic overwintering mission reveals that constant physical proximity in extreme environments can increase conflict, mistrust, and social withdrawal among team members, challenging the assumption that frequent contact always benefits team cohesion.
• Data from questionnaires and wearable sensors showed that crew members who spent more time in close contact reported higher levels of conflict and reduced perceived performance, indicating that in confined settings, proximity can be a source of stress rather than support.
• The team gradually formed subgroups based on shared language or nationality, providing social support but also risking social fragmentation and weakening cohesion in multicultural teams.
• These findings have important implications for long-duration space missions and other isolated environments like submarines and offshore platforms, highlighting the need to monitor social dynamics early and offer targeted team support.
• The study also validated the use of wearable proximity sensors in extreme conditions, enabling non-intrusive tracking of social interactions to better understand which behaviors alleviate or exacerbate stress.
