Step-by-step explanation:
The correct answer is social support, which refers to tangible and/or emotional support provided in times of need by family members, friends, and others. Social support is vital in helping individuals cope with stress, maintain physical health, and improve survival rates for various health conditions. It can take many forms, including advice, guidance, encouragement, emotional comfort, and tangible assistance like financial help.
Research demonstrates that social support has significant physiological effects, particularly in boosting the immune system during stress. Notably, individuals with strong social support have been linked to better survival outcomes in cases of cardiovascular disorders, breast cancer, and infectious diseases, including HIV. Studies also point out the connection between increased sociability and a decreased likelihood of contracting illnesses such as the common cold.
The role of social support extends beyond physiological responses to include fostering healthier behaviors and providing a care network vital for both caregivers and receivers. Therefore, it is one of the well-documented psychosocial factors that affect health outcomes across a person's lifespan.
