A recent study highlights a link between loneliness and increased frequency and intensity of nightmares. This research, which involved scientists from Oregon State University, the University of Arizona, the University of Tampa, and Whitworth University, underscores the importance of addressing loneliness due to its impact on health.
The study, published in the Journal of Psychology, reveals that loneliness is associated with higher stress levels, rumination, and hyperarousal—all factors contributing to more frequent and intense nightmares. These findings align with the evolutionary theory that a sense of belonging is crucial for human survival.
Colin Hesse, an OSU scientist, notes that loneliness affects physical, mental, and social well-being, much like hunger or fatigue signals unmet needs. He emphasizes that addressing loneliness might help reduce nightmares, though concrete interventions are still needed.
The study surveyed over 1,600 U.S. adults aged 18 to 81. Hesse highlights that quality sleep is essential for overall health and underscores the need to investigate psychological factors, like loneliness, that disrupt sleep.
The U.S. surgeon general’s office reports that loneliness is as risky as smoking in terms of premature death, with increased risks of heart disease, stroke, and dementia. Research was funded by the Flora Family Fund at Whitworth University.
