The negative physiological effects of human isolation have been documented in countless studies. Social isolation, it has been observed, unleashes an extreme immune response - a surge of stress hormones and inflammation in the body.
Loneliness also interferes with a whole range of everyday functioning, such as sleep patterns, attention and logical and verbal reasoning. Chronically lonely people have higher blood pressure, are more vulnerable to infection, and are also more likely to develop Alzheimer’s disease and dementia.
The more extreme studies in isolation and sensory deprivation have to be cut short after just a couple days due to the adverse effects of the experiments on the subjects: hearing phantom footsteps and seeing flashing lights and geometric shapes. Some subjects spent most of their day crouched on all fours.
These effects point to a reality we all know intuitively, we cannot flourish without healthy relationships. And while we may crave solitude occasionally, in the long term it's not good for us physically or mentally. It’s as though our bodies send off alarms to urge us back into relationships with other humans.
