How it's used
Refers specifically to the clinical diagnosis of chronic sleep deprivation rather than just a bad night of sleep. Native speakers often prefer the more casual verb phrase 瞓唔着 to describe the state of being unable to sleep, reserving this formal term for medical contexts or when discussing a persistent health condition.
Examples
He has developed insomnia recently and cannot sleep all night.
Do you have insomnia? Why are you always so lacking in energy?

to treat insomnia
Common mistake
Avoid using this term to describe a one-off night of poor sleep, as it implies a long-term medical issue. Use 瞓唔着 for general sleeplessness.
