Today on (June 16, 2025) in the presence of the head of departments and lecturer a symposium entitled (The sleeping in the view the biological and psychological aspects), was presented by (Dr. Mervan Yousif Huseyin) from the Medical Microbiology department , Where it has been explained about, Sleep is an important part of your daily routine —you spend about one-third of your time doing it. Quality sleep—and getting enough of it at the right times—is as essential to survival as food and water. Without sleep, you can’t form or maintain the pathways in your brain that let you learn and create new memories. Lack of sleep makes it harder to concentrate and respond quickly. This seminar discusses the Biological and Psycological aspects and how can we organise our sleep in the life, At the end of the symposium 1. Hajnik T, Lai YY, Siegel JM.
