     Since we are social beings, the quality of our lives depends in large measure on our interpersonal

relationships. One strength of the human conditions is our possibility to give and receive support from

one another under stressful conditions. Social support makes up of the exchange of resources among

people based on their interpersonal ties. Those of us with strong support systems appear better able to

deal with major life changes and daily problems. People with strong social ties live longer and have better

health than those without such ties. Studies over types of illnesses, from depression to heartdisease, show

that the presence of social support helps people defend themselves against illness, and the absence of

such support makes poor health more likely.

     Social support cushions stress in a number of ways. First, friends, relatives and coworkers may let us

know that they value us. Our selfrespect is strengthened when we feel accepted by others in spite of our

faults and difficulties. Second, otherpeople often provide us with informational support. They help us to

define and understand our problems and find solutions to them. Third, we typically find social

companionship supportive. Taking part in freetime 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-money aid, material resources, and needed services-that

reduces stress by helping us resolve and deal with our problems.
