"The Nightly Disease" refers to a condition characterized by the inability to sleep or maintain restful sleep, often leading to fatigue and cognitive impairment. This term is commonly associated with various sleep disorders, including insomnia and sleep apnea, which disrupt normal sleep patterns and can affect overall health. Individuals suffering from this condition may experience symptoms such as difficulty falling asleep, frequent awakenings during the night, and excessive daytime sleepiness. Treatment options often include lifestyle changes, cognitive behavioral therapy, and, in some cases, medication to help improve sleep quality and duration.
