Summary:
Since the first surgeon general was sworn into office in the
19th century, the Office of the Surgeon General has positioned
itself as the leading voice on public health matters in the United States. In
recent history, the office has had its highest profile campaigns rallying
against issues such as tobacco use, obesity, and HIV/AIDS. Considering the
combination of prevalence, morbidity, and mortality associated with these
health issues, there is no doubt that any effort to stem the tide was a
worthwhile endeavor.
When Dr. Vivek Murthy became the surgeon general in 2014, his
office continued the historical campaigns against these health issues. At the
same time, Dr. Murthy began investigating a looming epidemic within our
borders: loneliness and social isolation.
It may be hard to convince the average person that
loneliness is a problem of similar scale as tobacco use, obesity, or AIDS.
There is no question that loneliness is unpleasant, even if it only lasts for a
few moments. But the notion that one’s state of mind can predispose to disease
or premature death somehow feels like a stretch. Addressing this skepticism,
Dr. Murthy writes in his book about Dr. Julianne Holt-Lunstad, a psychologist
at Brigham Young University who also faced a great deal of cynicism surrounding
her research into the effect of social relationships on “everything from our
behavior to our cellular function.” She had a breakthrough in 2010 when she
published a massive study analyzing the health outcomes of over 300,000
participants, categorized by their degree of social connectedness. She found
that social isolation was significantly linked to premature death, representing
a risk nearly as serious as pack-per-day smoking, and more serious than
obesity, alcohol use, and lack of exercise. Dr. Holt-Lunstad’s research spurred
further studies which linked loneliness to heart disease, stroke, and
depression, amongst other diseases.
These findings are hard to ignore, especially in light of
the ongoing opioid addiction crisis and rises in teenage depression and
suicide, all of which have been linked to loneliness and social isolation. In Together,
Dr. Murthy weaves together scientific research, personal anecdotes, and current
events to create a manifesto for tackling the next great public health crisis.
