Researchers surveyed more than 2,200 young adults and found that between 25% and 30% of the participants felt lonely sometimes, while another 5% reported they frequently felt lonely. Furthermore, they observed that the lonelier people were 24% more likely to feel tired and have difficulty concentrating during the day. Study author Dr. Louise Arseneault adds, “Diminished sleep quality is one of the many ways in which loneliness gets under the skin, and our findings underscore the importance of early therapeutic approaches to target the negative thoughts and perceptions that can make loneliness a vicious cycle.”
