“Ahhh, it’s morning,” you say to yourself as you get up from yours sleep. Until you roll over, and angrily realize it’s four or five hours earlier than you’d like it to be.
According to Land of Beds’ UK Sleep Report 2026, 88% of Brits now wake up at least once a night, with a separate Dreams survey finding that 69% do so between 2am and 4am.
Worse still, 61% struggle to get back to sleep afterwards. And staying up late can be incredibly frustrating, especially if it bothers you further closing of the eyes – or prevents you from receiving sleep at all.
So what causes these unwanted wake-up calls? Here are some of the reasons for interrupted sleep between 2am and 3am, along with expert advice to prevent it.
Stress or anxiety
Your sleep can be disturbed by events that cause anxiety or emphasizes in your waking life, with sleep expert, Dr Deborah Lee, from Doctor Fox saying it is “among the biggest contributors to 3am wake-ups”.
“Cortisol, often referred to as the stress hormone, naturally begins to rise in the early morning hours as your body prepares to wake up,” she explains.
“However, if you’re feeling anxious or under prolonged stress, this increase may occur earlier or more sharply, making it difficult to fall back asleep and creating a disrupted rest cycle.”
Thankfully, a consistent shutdown routine can help, along with cutting down on late-night screen use and keeping a notebook by your bed to download racing thoughts if they pop up at night.
Poor sleep hygiene
Maybe you stay up later than you should, or you always try to sleep long before you’re tired. Maybe you don’t keep a regular sleep schedule. Or you I DO get to bed on time, but end up staring at your phone for an hour first.
Bad sleeping habits can cause your body to wake up at an inconvenient time, even when it seems unlikely.
To treat an uneven sleep cycle, the sleep physiologist and Sleepyhead Clinic director Stephanie Romiszewski advises creating a planned routine to follow consistently.
She tells subway: ‘Get up at the same time every day and don’t go to bed until you feel sleepy. You will notice that if you wake up at the same time every day, it will start to become your regular time. This is the order in which you should do it.’
It’s also important to try – no matter how tired you are – not to let your sleep problem rule your life by keeping up with exercise and social time.
“We have to let our brains understand that the only option for sleep will be the usual night,” adds Stephanie. “Once we start fitting our whole lives around a sleep problem, we actually end up making it worse.
Don’t fall into the trap of thinking you can just ‘relax’ a sleep problem.
“Doing things for relaxation and nightmarish cutting back can be a very proactive means of making sure you don’t have sleep problems, but it’s not reactive,’ shares Stephanie.
“If you have trouble sleeping and wake up at 3 or 4 in the morning every night, that’s normal. Unfortunately, it won’t be changed by relaxing before you go to bed.
“It’ll be a very pleasant way to spend your evening and that’s important to keep your anxiety or worry levels down – but it’s actually doing very physical and actionable things with your sleep (like creating a routine) that will get you back on track.”
Increased blood sugar or alcohol consumption
Low blood sugar at night can trigger the release of adrenaline and cortisol, both of which can wake you up in the early hours, says Dr Lee.
This may be more common in people who skip meals, eat very light dinners, or consume insufficient protein during the day. When the body senses a drop in energy, it can respond by increasing alertness.’
Have you experienced trouble sleeping between 2 and 3 a.m., and if so, what do you think is the cause?

Eating or drinking alcohol
Similarly, drinking alcohol can lead to something called ‘rebound insomnia’ as it is metabolized in the body during the night – despite the fact that it initially makes you fall asleep faster.
As well as being a diuretic, meaning you’re more likely to get up to urinate, it also reduces the time spent in deeper sleep stages and relaxes your throat muscles, potentially lowering blood oxygen levels and therefore waking you up.
Along with avoiding alcohol, Dr Lee recommends eating a balanced diet, with enough protein and healthy fats, to help stabilize energy levels at night.
Hormonal changes
According to Dr Lee, hormones ‘play a big role in sleep regulation’ and menopause, perimenopause and pregnancy can lead to night waking.
“During menopause and perimenopause, fluctuating levels of estrogen and progesterone can contribute to night sweats, temperature sensitivity, and anxiety,” she continues. “In pregnancy, physical discomfort, increased urination and hormonal changes can also disrupt sleep.
Unfortunately, there’s not always a quick fix if it’s triggering your internal alarm from 2am-4am, ‘but small environmental tweaks and supportive routines can make a significant difference.’
An underlying medical issue
In some cases, an underlying medical condition can cause you to wake up at night or early in the morning. These may include:
- DEPRESSION
- Sleep apnea
- Reflux (GERD)
- Low blood sugar
- Frequent urination
- Restless Legs Syndrome (RLS)
- Chronic pain conditions, such as arthritis, fibromyalgia, or peripheral neuropathy.
If you know you already have one of these conditions, then this could potentially explain why you’re waking up so early.
If not, consider whether you’ve noticed any physical symptoms along with your recent period of disrupted sleep.
- Do you wake up suddenly to urinate during the night, or more often than usual, despite not changing how much you drink?
- Do you feel faint or light-headed during the wake-up call between 02:00 and 03:00, when you normally get up, or at other times of the day?
- Do you regularly wake up with a headache, cough or pain? Or does your significant other tell you that you snore, or that you feel uncomfortable breathing at night?
If the answer to any of these is yes—or you have any concerns about another symptom that may be contributing—seek advice from a medical professional.
Finally, some medications can also affect your sleep. Talk to your doctor if you have any concerns.
Is it normal to wake up at 2 or 3 in the morning?
Well, it really depends on the cause.
Again, if you have any unusual symptoms then it’s worth making an appointment to get checked out. But sometimes, and even more so with ageour sleep patterns change.
And in general, Stephanie notes that downtime is usually quite ‘normal’ – especially ‘when things in our lives change, or when we’re going through stress, even when we’re going through happy things…’
“Our brain is just trying to adapt. Sleep is just adapting to all these different situations. It’s no wonder that in the short term our sleep can be a bit funny and we just have to allow it, and then let it go back to normal.’
However, Stephanie warns that if you have persistent sleep problems, you should seek medical help.
She says: ‘If it’s been more than three months then absolutely see your GP.
“If you haven’t changed anything (in your life) – and it’s getting severe and it’s constantly affecting you, we’d suggest it’s definitely time to contact your GP.
“After three months, any kind of sleep problem can become habitual, like a pattern for your brain. At that point, no amount of getting rid of the original trigger will get rid of the problem. You can get rid of stress, for example, but the sleep (issue) may remain.”
“That’s when you need insomnia treatment, such as Cognitive Behavioral Therapy (CBT), to help change the behavior pattern – for which you’ll need to see your GP or a sleep expert.
