Humans are social creatures and respond well, both physically and emotionally, to social activity. A study shows that denying the body this activity may affect sleep quality and even lead to poor health.
Loneliness and poor health have been related, but this study shows that the reason might be because of poor sleep quality. Researchers found that, on the scale used, each unit increase in loneliness correlated to a 8% increase in sleep fragmentation.
Much like depression, sleep issues are a result of loneliness but also a symptom. Loneliness can also lead to anxiety, depression, and stress.
The research supports the notion that individuals who see themselves as less connected to others have more fragmented sleep. Quality of sleep could therefore affect how we perceive ourselves socially and among others.
