A recent study into 2,000 young adults by postdoctoral researcher Dr Timothy Matthews at King’s College London found that lonelier people reported poorer sleep than non-lonely people and were 24 per cent more likely to feel tired and have difficulty concentrating during the day – an association that remained after controlling for mental health problems. The link was almost 70 per cent stronger among those who had been exposed to severe forms of violence in their teenage years.
“When you feel like you’re on your own, the world seems like a more threatening place, which could make it harder to sleep restfully,” Matthews says. “This perception of threat in the environment seems to be even stronger for people who’ve been exposed to an objective threat during their lives, such as being a victim of violence.” This also helps us understand why lonely people’s immune systems could be primed to fight bacterial infection from a wound, rather than viral infection; they are anticipating being attacked by a predator, with no tribe to defend them.
