Apparrenty it’s happening enough to grab the attention even of secular “non-nonsense” scientists.
The issue of waking up right at three a.m.
Are there physiological reasons for it?
We find it difficult to believe that so many reporting that they awaken on three a.m. on the dot could be solely biological.
Might it not have a spiritual underpinning–particularly knowing that three a.m. has spiritual connotations (the inverse og three p.m., and also the end of the three hour time-frame of many occult, wiccan, and satanic rituals (which begin at the stroke of midnight and can unleash spirits into our midst)?
But anyway, to humor the scientists:
Reports the Irish News: We asked sleep expert Martin Seeley to explain why a lot of people wake to see their bedside clock displaying the dreaded ‘3:00′.
He told us all about the three most likely reasons for these early-morning awakenings, and offers advice on when you should worry about it.
WAKING up at 3am every night can be annoying, but it’s actually a common experience – and understanding why it happens can help you to take corrective steps that will result in a better night’s sleep.
We asked sleep expert Martin Seeley to explain why a lot of people wake to see their bedside clock displaying the dreaded ‘3:00′.
He told us all about the three most likely reasons for these early-morning awakenings, and offers advice on when you should worry about it.
1. Your sleep cycles are naturally waking you up
“Your body’s sleep is divided into cycles, each lasting about 90 minutes,” Seeley explains.
“Over the course of a night, you typically go through four to five of these cycles.
“Waking up at the end of one isn’t unusual, and for many people, this happens to coincide with the early hours of the morning – often around 3am.”

“Think of it as your body doing a ‘systems check’ between cycles. At this point in the night, you’re likely in a lighter stage of sleep, which makes it easier for small disturbances – like a noise outside or even a shift in your body temperature – to wake you up.”
While this is a natural part of how our bodies work, Seeley notes that external factors can make these wake-ups more frequent.
“If your bedroom isn’t optimised for sleep, whether it’s too warm, too bright, or too noisy, you’re more likely to notice these natural awakenings and struggle to fall back asleep.”
2. Stress is disrupting your hormonal balance
“If you’re feeling stressed or anxious in your daily life, this can have a big impact on your sleep,” Seeley explains.
“Around 3am, your body undergoes a hormonal shift. Melatonin – the hormone that helps you stay asleep – starts to decrease, while cortisol, the hormone that helps you wake up, begins to rise.
“This hormonal shift is part of your body’s natural circadian rhythm, which prepares you for the day ahead. However, stress can amplify this process.
“If you’re already dealing with elevated cortisol levels due to stress or worry, this early-morning spike can feel like an internal alarm clock going off too soon.”
Seeley adds that stress doesn’t just affect your hormones, it also impacts how deeply you sleep.
“When you’re stressed, your body spends less time in the restorative stages of deep sleep. This means you’re more likely to wake up during lighter stages of sleep, like the ones that occur around 3am.”
3. Your blood sugar levels are waking you up
Another factor that might be behind your 3am wake-ups is blood sugar regulation.
“During the night, your body uses stored energy to keep everything running smoothly while you sleep,” Seeley explains.
“But if your blood sugar levels drop too low, perhaps because of what or when you ate during the day, your body releases stress hormones like cortisol and adrenaline to stabilise them.”
While this process is designed to protect your body’s balance, it can also have an unintended side effect: waking you up.
To avoid this, Seeley suggests paying attention to what you eat before bed:
“A light snack that combines protein and complex carbohydrates – like a small piece of whole-grain toast with peanut butter – can help keep your blood sugar stable through the night.”
When should you be concerned about waking up at 3am?
“Occasional wake-ups are perfectly normal,” Seeley reassures.
“In fact, most people wake up briefly several times during the night without even realising it.”
However, he notes that frequent and disruptive awakenings could be a sign of an underlying issue.
“If you’re waking up at 3am three or more nights a week for several weeks – and especially if it’s leaving you feeling tired or irritable during the day – it’s worth taking action,” he advises.
Persistent 3am wake-ups could point to issues such as:
- Chronic stress or anxiety
- Poor sleep hygiene (e.g., inconsistent bedtimes or excessive screen use before bed)
- A disrupted circadian rhythm from irregular schedules
- An undiagnosed sleep disorder such as insomnia or sleep apnea
“If these awakenings are affecting your quality of life, it’s important to speak with a doctor,” Seeley advises.
“They can help identify any triggers and recommend evidence-based strategies for improving your sleep.”
