"Losing sleep over" is a commonly used phrase meaning to experience worry, stress, or anxiety that affects one's ability to sleep or get a good night's rest. It describes a state of mental preoccupation or concern that keeps an individual awake during hours that should be dedicated to rest.
This idiomatic expression refers to the notion that when one is consumed by a particular issue or problem, it tends to disrupt the natural sleep cycle, making it difficult to fall asleep or causing frequent awakenings during the night. The disturbance in sleep arises from the intense thoughts, concerns, or anxieties that occupy the mind, preventing it from entering a relaxed state conducive to sleep.
Often used metaphorically, "losing sleep over" implies that the issue or concern is significant enough to cause a considerable impact on an individual's emotional well-being or mental state. It suggests an inordinate amount of worry or preoccupation that overrides the body's natural inclination for restful sleep.
While it is normal to occasionally experience concerns or worries that temporarily disrupt sleep, "losing sleep over" tends to describe a more chronic or persistent state of mental distress that significantly interferes with one's ability to achieve the recommended amount of rest. It implies a burden or emotional weight that can adversely affect overall health and well-being if not addressed or resolved.
