Since We are social beings,the quality of our lives depends (in large measure) on our interpersonal relationships. One strength of the human condition is our tendency to give and receive support from one another under stressful circumstances. Social support consists of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to cope with major life changes and daily hassles (困难)? People with strong social ties live longer and have better health than those without such ties. Studies over a range of illnesses,from depression to heart disease?reveal that the presence of social support helps people fend off (挡开)illness,and the absence of such support makes poor health more likely.

Engaging in leisure-time activities with others helps us to meet our social needs.
while at the same time distracting (转移......注意力)us from our worries and troubles. Finally,other people may give us instrumental support一financial aid, material resources,and needed services—that reduces stress by helping us resolve and cope with our problems.
