5 Reasons You’re Waking Up Tired — And How to Fix It
When was the last time you truly woke up feeling energised and well-rested? For many, getting consistent, restorative sleep becomes more difficult as life moves on. Whether that’s due to childcare responsibilities, changing routines or external stressors, many of us still wake up tired despite thinking we’ve spent an adequate amount of time beneath the sheets.
Stephanie Romiszewski, a sleep physiologist and the author of Think Less, Sleep More comes across this problem regularly — and with clients ranging from shift workers and Premier League footballers to new parents and CEOs, she is acutely aware of how patterns of behaviour and sleep timing can influence how well-rested we feel once morning comes around. Below, Romiszewski shares her five key reasons why you’re waking up bleary-eyed, even after a decent night’s rest.
Inconsistent wake times
If you’re waking up at 6AM to get ready for work and then sleeping in until 9AM or 10AM on the weekends, you could be messing with your internal wiring. “If your ‘get up time’ moves around, your circadian rhythm never stabilises, so your body doesn’t know when to feel alert, which creates that heavy, groggy feeling in the morning,” says Romiszewski. “If you continue to snooze or change alarm times at weekends, you will perpetuate the feeling of grogginess.”
The solution? “Wake up at the same time every day.” This will become “the anchor that stabilises your circadian rhythm, builds sleep pressure properly and makes both sleepiness and alertness more predictable.”
Poor sleep quality
A good night’s rest can underpin almost every part of your day — from how you interact with your colleagues and friends to how approachable certain challenges feel. Clock enough poor quality sleep — or, conversely, not enough good quality sleep — and you’re wide open to waking up unrefreshed. Despite what many people may think, redressing this balance doesn’t come down to a ‘more is more’ philosophy.
Rather, “sleep is made up of cycles, and if those are fragmented or mistimed, you can spend long enough in bed but still wake up unrefreshed,” explains Romiszewski. “You can sleep for longer and still have poor sleep quality, and that rarely leaves you feeling good.” With many of us using wearable tech like smartwatches or rings, it can be tempting to become focused on sleep duration, “because it feels measurable, but it is one of the things we have the least direct control over,” Romiszewski continues. “You cannot simply decide to sleep longer, but what we do have more influence over is sleep quality and that requires consistency.”
Sleep timing
You might be getting a solid seven or eight hours, but if those hours are misaligned with your body’s internal clock, you could still be setting yourself up for a groggy morning. Think late nights, later lie-ins and a sleep schedule that drifts further from what your biology actually wants. “Sleep that is out of sync with your internal clock is lighter and less restorative,” says Romiszewski — meaning the hours you’re logging aren’t necessarily the hours of rest you think you’re getting.
The fix here runs parallel to tackling inconsistent wake times: anchor your schedule. Prioritising a consistent bedtime, even when it feels uncomfortable, gradually aligns your sleep window with your circadian rhythm — and the quality of your rest should follow.
Sleep anxiety and overthinking
As you may already know, there’s a cruel irony to sleep anxiety: the harder you try to force sleep, the further away it feels. For many people, bedtime becomes a mental battleground — a space for rumination, performance anxiety and clock-watching — and that hypervigilance doesn’t simply switch off once your eyes close. “Sleep anxiety and overthinking sleep keep the brain alert at night,” says Romiszewski, “and carry through into how you feel the next day.”
The key shift is learning to detach your sense of control from sleep itself. Your bedroom environment can help — reducing obvious disruptions like heat, noise and light matters, since these “can make sleep lighter and more fragmented” — but Romiszewski is clear that this only goes so far. Such tweaks “will not compensate for poor sleep timing or inconsistent routines.” Approaching sleep with less urgency, treating the bedroom as a place for rest rather than a problem to be solved, is where the real work gets done.
Underlying sleep disorders
Sometimes, tiredness persists no matter how diligently you overhaul your routine — and in those cases, the issue may run deeper than habits alone. Conditions like sleep apnoea, for example, allow sleep to happen but disrupt its architecture so fundamentally that the restorative work sleep is supposed to do simply doesn’t happen. “It can be a sign of things like sleep apnoea, where sleeping is not the problem, but the actual sleep architecture is,” explains Romiszewski.
Naturally, there are tell-tale signs to look out for. “If you feel excessively sleepy during the day or need to nap to get through, it may be a sign and it is worth speaking to your GP.” No amount of consistent wake times or bedroom optimisation will resolve something that requires clinical attention — so if tiredness remains a fixture of your days despite your best efforts, it’s worth ruling out an underlying cause.
