Nursing's Hidden Blessings

One in five Americans is currently taking care of another adult, voluntarily tending to an ill or frail loved one. And as the Baby-Boomer generation ages, that obligation is likely to increase. The burden takes a serious toll on caregivers, leading to poorer health and even an increased risk of death.

But what is it that actually takes the toll? Is it the physical wear-and-tear of feeding and bathing a needy relative? Is it simply that caregivers have too much work and too little time and energy? Or is it the emotional costs of watching a loved one deteriorate, or the anticipation of loss? Or all of this rolled together?

Interestingly, these possibilities have never really been sorted out—until now. A team of public health researchers, headed by Stephanie Brown at the University of Michigan, decided to explore these questions by examining the histories of more than 3000 elderly married people over several years. The couples were all living together in their own homes, but the level of neediness varied, as did the commitment of caring time. The researchers tracked the health and the survival rate of the caregivers, all 70 or older.

The results were interesting and a bit surprising. As reported in the April issue of the journal Psychological Science, those who were providing the most care for their spouses—14 or more hours a week—actually had a lower mortality rate than did those who had no care obligation. This was true regardless of the spouse’s neediness, including cognitive decline. This suggests that the health problems of caregivers may not result from the actual burden of caring. Indeed, caring may have a tonic effect under certain circumstances, which may offset the emotional toll of witnessing a spouse’s deterioration and worrying about life alone.

Why would that be? It’s not entirely clear, but it may be that the very act of giving acts as a buffer, moderating the untoward physical consequences of chronic stress, including immune dysfunction. It’s also possible that the hormones associated with helping—oxytocin, for example—actually help the body’s cells repair and store nutrients. Whatever the mechanism, it appears that nurturance is a blessing at the microscopic level.

Interesting post. I'd like to know if anything else is found out.

I wonder if people who watch loved ones deteriorate in someone else's care and do nothing about it have the same health problems as carers. Or does a sense of purpose help carers live longer?

I have experienced and observed in others,the mental health benefits of volunteering ones time or simply doing something for someone without telling anyone about the deed.Why not physical benefits as well- we all know about the mind/body connection.
