Poor sleep and loneliness may reinforce each other
Loneliness is a painful feeling of having less connection than you want.
Research reviews have found that loneliness is linked with sleep problems, including insomnia symptoms and poor sleep quality.
One explanation is that people who feel lonely may stay alert to possible social threats, making it harder to sleep well.
A study found that people who had too little sleep wanted more distance from others, and poorer sleep quality was followed by greater loneliness the next day.
People who watched videos of sleep-deprived participants also judged them as lonelier and less appealing to spend time with.
The researchers said even brief encounters with sleep-deprived people could leave others feeling lonelier.
Together, the findings suggest that poor sleep and loneliness can feed into each other, though sleep is not a cure for loneliness.
Research reviewed in a Psychology Today article suggests poor sleep and loneliness may reinforce each other.
Studies cited in the article link loneliness with sleep disturbances and find that insufficient sleep can lead people to keep more distance from others.
The article says loneliness-related vigilance to social threats may contribute to restless or poor-quality sleep.
It also describes research in which observers rated sleep-deprived people as lonelier and less desirable to approach.
The article presents sleep as a factor that may shape vigilance, mood and social behavior, not as a cure for loneliness.

- The article says loneliness-related vigilance may disrupt sleep, while sleep loss may change social behavior and push others away.
This story does not have two clearly opposing sides.
When that social context is absent or uncertain, the sleeping brain may remain more vigilant, making loneliness and poor sleep mutually reinforcing.
They suggest sleep loss does not simply make people feel worse internally.
