The term "sleep issues" refers to any problems or difficulties that a person may experience related to their sleep. This can include a variety of different conditions, such as insomnia (trouble falling or staying asleep), sleep apnea (interrupted breathing during sleep), restless leg syndrome (an urge to move the legs while trying to fall asleep), and other disorders that affect the quality or duration of sleep. Sleep issues can have a significant impact on an individual's overall health, mood, and well-being, making it important for them to be addressed and managed appropriately.
