Many COVID-19 survivors appear to resume their normal lives after a period of illness, but a new study indicates there might be lingering aftereffects that are less noticeable - sleep issues. The study was published on February 4, 2024, in Frontiers of Public Health, where Vietnamese scientists conducted a survey involving over 1,000 recovered patients, none of which required hospitalization or had a prior history of insomnia or psychiatric conditions. The study discovered that over 76% of the participants reported experiencing insomnia known as long COVID within six months following their initial infection, with nearly 23% stating their insomnia was severe. Research leader Huong Thi Xuan Hoang from Phenikaa University noted the high prevalence of sleep disruption among survivors and found a correlation between those with preexisting conditions like cardiovascular disease, diabetes, and cancer, and higher insomnia rates. The study did not prove that COVID-19 causes insomnia but emphasized a clear association. This research underlines the importance of sleep health in the wake of a COVID-19 infection. Experts strongly advise those suffering from any sleep troubles post infection to seek immediate medical help. Preliminary steps towards better sleep include measures such as a warm shower before bedtime, shutting down electronic devices an hour before sleep, daily exercise, and avoiding caffeine after 4 p.m. Dr. Abhinav Singh of the Indiana Sleep Center recommends cognitive behavioral therapy as the “gold standard” for insomnia treatment, emphasizing the importance of optimal sleep for overall well-being.
