The Dangers of Loneliness

Friendship is a lot like food. We need it to survive. What is more, we seem to have a basic drive for it. Psychologists find that human beings have fundamental need for inclusion in group life and for close relationships. We are truly social animals.

The upshot is, we function best when this social need is met. It is easier to stay motivated, to meet the varied challenges of life.

In fact, evidence has been growing that when our need for social relationships is not met, we fall apart mentally and even physically. There are effects on the brain and on the body. Some effects work subtly, through the exposure of multiple body systems to excess amounts of stress hormones. Yet the effects are distinct enough to be measured over time, so that unmet social needs take a serious toll on health, eroding our arteries, creating high blood pressure, and even undermining learning and memory.

A lack of close friends and a dearth of broader social contact generally bring the emotional discomfort or distress known as loneliness. It begins with an awareness of a deficiency of relationships. This cognitive awareness plays through our brain with an emotional soundtrack. It makes us sad. We might feel an emptiness. We may be filled with a longing for contact. We feel isolated, distanced from others, deprived. These feelings tear away at our emotional well-being.
