Love and intimacy and their impact

Love and intimacy are the roots of what makes us sick and what makes us well. I am not aware of any other factor in medicine - not diet, not smoking, not exercise, not drugs - that has a greater impact on our quality of life, the incidence of illness and premature death.

Loneliness and Isolation

Medicine today tends to focus primarily on the physical and mechanistic: drugs and surgery, genes and germs, microbes and molecules. However, there isn’t any other factor in medicine – not diet, not smoking, not exercise, not stress, not genetics, not drugs, not surgery – that have a greater impact on our quality of life, the incidence of illness and premature death from all causes than loneliness and isolation.

Love and intimacy — our ability to connect with ourselves and others, is at the root of what makes us sick and what makes us well, what causes sadness and what brings happiness, what makes us suffer and what leads to healing. If a new drug had the same impact, virtually every doctor in the country would be recommending it for his or her patients. It would be malpractice not to prescribe it — yet, with few exceptions, we doctors do not learn much about the healing power of love, intimacy, and transformation in our medical training.

There is a deep spiritual hunger in this country. The real epidemic in our culture is not only physical heart disease but also what I call emotional and spiritual heart disease. The profound sense of loneliness, isolation, alienation, and depression that are so prevalent in our culture with the breakdown of the social structures that used to provide us with a sense of connection and community. It is, to me, a root of the illness, cynicism, and violence in our society.

We are creatures of community. Those individuals, societies, and cultures who learned to take care of each other, to love each other, and to nurture relationships with each other during the past several hundred thousand years were more likely to survive than those who did not. Those people who did not learn to take care of each other often did not make it. In our culture, the idea of spending time taking care of each other and creating communities has become increasingly rare. Ignoring these ideas imperils our survival.

Awareness is the first step in healing, both individually and socially. Part of the value of science is to increase the level of awareness of how much these choices matter that we make each day. Not just a little, but a lot, and not just to the quality of life but also the quantity of life – to our survival. When we understand how important these issues are, then we can do something about it. These include:

• spending more time with our friends and family
• communication skills
• group support
• confession, forgiveness, and redemption
• compassion, altruism, and service
• psychotherapy
• touching
• commitment
• meditation

When we increase the love and intimacy in our lives, we also increase the health, joy, and meaning in our lives.
