Research suggests that there is a direct biological link between being lonely and ill health. These negative impacts inside the human body may be stopped with social contact.

They have found that loneliness is tied to hardening of the arteries (leading to high blood pressure), inflammation and even problems with memory and learning. In a study at UCLA, they observed that certain genes were being expressed differently in the immune systems of lonely people. They discovered that several keys genes involved in antiviral and antibody production were underexpressed. In other words, the human body was less able to fight off viral threats making people that are socially isolated more vulnerable to cancers, infections, heart disease and other illnesses. In fact, loneliness increases the likelihood of mortality by 26%.

Loneliness can also significantly reduce the quality of sleep. Lonely people tend to wake up more frequently during the night and actually spend less time in bed.

loneliness, impact on our health


Being lonely can make a person hyper-sensitive to negative social behaviours causing them to fall even further into loneliness. In other words, being alone makes one feel unsafe. The reason for this can be traced back to early human evolution when people needed to band together in order to stay alive. They all needed to work with each other to hunt, gather food and fight off enemies. Those that tended to stray away from the group risked physical harm. Lonely individuals are more prone to depression and are at a greater risk of cognitive decline. One study concluded that lonely people have a 64% increased chance of developing dementia. Loneliness and low social interaction are predictive of suicide in older age (O’Connell et al, 2004)
