maybe is has something to do with the fact that Insomnia can be caused by a variety of factors, including psychological conditions (such as stress, anxiety, and depression), medical conditions (like chronic pain, asthma, and heart disease), lifestyle choices (such as irregular sleep schedules and caffeine or alcohol consumption), and environmental factors (like noise and light). Because insomnia can result from so many different sources, a one-size-fits-all cure is impractical.
