Objective:

To explore how a close partner's presence affects homeostatic responses in adults and infants.

Approach:
  • Study Design: Three experiments involving 180 adults in romantic relationships and 56 infants were conducted to assess physiological responses to carbohydrate, cold, and mild electric shock challenges, both alone and with a partner.
Key Findings:
  • Partner presence was associated with a 14.6% lower cumulative glycemic response in adults after carbohydrate consumption, with a 23.9% reduction between groups.
  • Social proximity reduced thermoregulatory responses to cold by 6.8% within participants and 16.2% between groups.
  • Lower sympathetic responses to stress were observed in both adults and infants when a partner was present.
  • The glucose effect persisted after accounting for physiological stress and physical touch.
Interpretation:

The study suggests that social physiology may play a significant role in homeostatic responses.

Limitations:
  • Effects observed were modest.
  • Long-term health implications of the findings remain unknown.
Conclusion:

Homeostasis may be influenced by social presence, indicating a complex interaction between physiology and social relationships.
