Insomnia is often recognized as the most common sleep disorder affecting Americans. It is characterized by difficulty falling asleep, staying asleep, or waking up too early and not being able to return to sleep. Insomnia can be triggered by various factors, including stress, anxiety, certain medications, and lifestyle choices. Its prevalence is high in the general population, with a significant number of individuals reporting symptoms at some point in their lives.

In contrast, while conditions such as sleep apnea are also widespread, they predominantly affect specific populations, often related to obesity or anatomical factors. Restless leg syndrome and narcolepsy are less common than insomnia and typically involve more specific symptoms that limit their prevalence in the general population. Understanding the ample reach of insomnia helps in recognizing its impact on daily functioning and overall health, making it a critical area of focus in sleep medicine.
