Perceived social support and belongingness bolster immune function by reducing stress and its physiological consequences.

1. Relevant knowledge points and concepts
- Social support buffers stress: the buffering hypothesis states that feeling supported lessens the psychological impact of stressors.
- Stress affects the HPA axis and sympathetic nervous system, elevating cortisol and catecholamines, which suppress immune processes (e.g., T-cell activity, antibody production) and increase inflammation (e.g., IL-6, CRP).
- Positive social ties are associated with faster wound healing, stronger vaccine responses, and lower inflammatory markers—indicators of stronger immune functioning.

2. Step-by-step reasoning
- Step 1: Feeling liked/encouraged reduces perceived threat and emotional distress.
- Step 2: Reduced distress lowers activation of the HPA axis and sympathetic nervous system.
- Step 3: Lower cortisol and catecholamine levels remove inhibitory effects on immune cells, allowing better cell-mediated and humoral responses.
- Step 4: Lower chronic inflammation and improved cellular responses manifest as stronger immune functioning (faster healing, better antibody response).

3. Calculations/intermediate steps
- No numerical calculations are required. The chain of physiological causation (social support → lower stress hormones → improved immune markers) serves as the logical intermediate steps.

4. Why the correct answer is correct
- Empirical research supports that supportive intimate relationships predict enhanced immune outcomes: greater antibody titers after vaccination, more robust T-cell responses, and faster tissue repair. These findings directly link feeling liked/encouraged to stronger immune functioning.

5. Why the other options are incorrect
- "Reduced serotonin levels.": Social support generally increases positive mood and is not associated with decreasing serotonin; reduced serotonin is linked to depression, not social encouragement.
- "Reduced endorphin levels.": Endorphins (natural pain relievers/pleasure mediators) tend to increase with positive social interaction, not decrease.
- "Mindfulness meditation.": This is an intervention, not an outcome produced by feeling liked/encouraged; while it can affect stress and immunity, it is not the specific consequence described.

6. Conclusion
All reasoning and evidence confirm the correct answer: feeling liked and encouraged by intimate friends and family promotes stronger immune functioning. This matches the provided answer.
