Chronic insomnia has been linked to a range of medical problems, from loss of concentration to high blood pressure…But can getting up throughout the night to tend to new baby cause long-term health problems as well?

In recent years, sociologists and epidemiologists have begun studying the long-term effects of loneliness. It turns out to be really dangerous. We are social primates, and when we’re cut off from the social network, we are more likely to die from just about everything (but especially heart disease).

Social relationships are just as important to health as other common risk factors like smoking, lack of exercise or obesity, new research shows…The researchers concluded that having few friends or weak social ties to the community is just as harmful to health as being an alcoholic or smoking nearly a pack of cigarettes a day.
