Living with a chronic, day-to-day health issue can make it difficult to tell when it’s time to stop managing it alone and get advice from a GP or another healthcare professional.
That uncertainty often applies to sleep. More people than ever report struggling to get proper rest, and estimates suggest around 17 percent of Americans experience some form of chronic insomnia—yet many never receive a diagnosis or treatment.
One reason is that the line between “bad sleep” and insomnia isn’t always clear. Ongoing poor rest can spill into nearly every part of daily life, from irritability and low mood to fatigue, memory lapses, and a persistent sense of mental fog.
To simplify things, Dr Sunny Nayee has shared a straightforward way to gauge when sleep problems may have moved beyond lifestyle habits and into insomnia: the “3-3-3 rule.” If you meet the criteria across all three threes, it’s a sign you should raise it with a clinician.

Although more than 30 million Americans are thought to deal with insomnia symptoms regularly, only about one in five cases are identified—meaning many people simply push through without medical support.
Dr Nayee says a practical threshold is duration and frequency. “If you experience disrupted sleep at least three nights a week for at least three months, medical practitioners no longer regard it as lifestyle related but in the realm of insomnia”, Dr Nayee said.
If sleep has been an ongoing issue for you, the 3-3-3 rule can be used as a quick self-check. Ask yourself three simple questions that cover frequency, how long it’s been happening, and whether it’s affecting your daytime functioning.
If the answer to all three is yes, your doctor may assess you for chronic insomnia disorder.
Dr Nayee also noted that insomnia doesn’t always look like lying awake all night. “A common misconception is that people think insomnia is staring at the ceiling and not sleeping at all. However, it’s defined by the impact it has throughout the day.
“If you find that poor sleep hygiene is having an instrumental impact on your mood, concentration and ability to function, then it may be considered a clinical condition.”

There are also warning signs that your sleep disruption may be developing into something more persistent. One that many people in modern workplaces will recognize is relying on caffeine just to get through the day.
Dr Nayee has also highlighted additional indicators such as ongoing tiredness, difficulty concentrating, and changes in mood or motivation when sleep problems continue.
If you do receive an insomnia diagnosis, there are several approaches a doctor may recommend. Often, the starting point is improving sleep hygiene—such as eliminating screen use in bed and keeping your bedroom environment consistent for rest.
Other options can include cognitive behavioural therapy (CBT), which aims to reshape thoughts and behaviours that interfere with sleep, as well as regular exercise to support the biological signals that help regulate your sleep cycle.
In some cases, medication may be discussed, including melatonin supplements. Doctors may also advise reducing alcohol and cutting back on caffeine, both of which can make it harder for the body to settle into deep, restorative sleep.
