How to reset your body clock for better sleep

Is your sleep out of shape after the holidays? You’re in good company. Over the festive period, late-night dinners stretch beyond midnight, our routine gets disrupted, we find our screen time getting longer, while our social calendar seems somehow to keep refilling itself.

By the time March arrives, many of us are back at work, but our bodies are still living in festive mode.

You might be getting into bed at a reasonable hour, yet lying there wide awake. Or, you fall asleep quickly but wake at 3 or 4 am with a mind that wants to review everything you said at dinner, everything you need to do this week, and everything you didn’t do last year.

People often say “My sleep is broken,” but usually it’s not broken. It’s shifted.

Sleep is not just a physical function; it’s closely tied to mood, stress tolerance, focus, and the way we relate to ourselves and others. When sleep is off, small challenges feel heavier. You might notice you’re more reactive, teary, flat, or anxious—even if nothing ‘major’ has happened.

Then, an unhelpful loop begins: you worry about not sleeping and that worry makes it harder to sleep, and suddenly bedtime starts to feel like a test you can fail.

The good news is that your body clock (your circadian rhythm) is responsive. In many cases, you don’t need a dramatic overhaul or a strict regime to ‘fix’ sleep. What helps most is a steady reset: a few consistent anchors that gently signal to your brain and body, “We’re back to regular life now.”

In this article, we’ll look at why post-holiday sleep disruption happens, realistic steps you can take for better sleep and how to know when it might be worth getting extra support.

Why post-holiday sleep disruption happens

Your circadian rhythm is an internal timing system that helps regulate sleep, alertness, appetite, and energy across a 24-hour cycle. It thrives on time cues from your environment—light exposure, meal timing, activity, and social routine. During the holidays, those cues often shift all at once: you sleep later, eat later, spend more time indoors, and use screens more at night. Even if you want to snap back to your usual schedule, your body may take a week or two to catch up.

Holidays can be genuinely joyful, but they can also be intense: family dynamics, travel stress, work deadlines before a break, financial pressure, or feeling lonely while everyone else seems busy. Stress activates the body’s arousal system, which is helpful during the day but gets in the way of sleep at night. This is why some people feel tired yet wired: the body is exhausted, but the mind stays on duty.

If you’ve had a few nights of poor sleep, it’s natural to start monitoring your sleep closely: “What time is it?” “How many hours left?” “If I don’t sleep, tomorrow will be a disaster.” The insomnia worry loop is real, and common. It increases arousal and makes sleep less likely. In counselling, we often work with this exact cycle—because changing the relationship with sleep can be just as important as changing your schedule.

A practical 2 week reset plan

Think of the next two weeks as a gentle recalibration. You’re giving your brain and body consistent signals, rather than forcing sleep through sheer effort.

If you do only one thing, pick one wake-up time and protect it, even on weekends. A steady wake-up time is one of the strongest ways to shift the body clock earlier. It may feel counterintuitive when you’ve slept poorly, but sleeping in tends to prolong the reset.

Choose a wake-up time you can keep most days. If you’re exhausted, aim for an earlier bedtime rather than a later wake-up.

When you wake up, get outdoor light within the first hour of waking. Morning light is a powerful cue for circadian timing. In Hong Kong, this can be as simple as stepping outside for a brisk walk, getting a coffee on foot, or doing a few stretches near a bright window. Aim for 10 to 20 minutes, even when it’s cloudy – it still helps.

Try to keep your caffeine to the morning. Caffeine stays in the body longer than most people expect. Even if you can fall asleep, caffeine can reduce sleep depth and increase night awakenings. If you’re sensitive, stop by early afternoon. Notice also the hidden sources: milk tea, matcha, chocolate, and some supplements.

Many people aim for a perfect nighttime routine and then feel they’ve failed when they can’t sustain it. A better approach: a 30–60 minute buffer that helps your nervous system downshift.
Try picking two downshifting activities: a warm shower, gentle stretching, light reading (a physical book is better), calming music, journalling. If you’re a parent or working late, you can shorten the buffer. Even 10 minutes is a signal.

Make your bed a cue for rest. If your bed has become a place for scrolling, working, or worrying, your brain learns to associate it with alertness. Evidence-based insomnia treatments often focus on rebuilding bed = sleep cues.

If you’re awake and restless for a long time, get up and do something quiet in dim light (reading, calming audio). Return to bed when sleepy. This can feel annoying, but it reduces the long-term pattern of lying awake in frustration.

If you wake at 3am, thoughts whirling, those thoughts can often feel urgent. At 3 a.m., your brain is tired, less flexible, and more threat-focused. The goal is not to ‘solve life,’ but to lower arousal.

Firstly, name what’s happening -  “This is my worry brain doing a night shift.”

Then, contain it. Keep a notepad by the bed. Write the thought’s theme as a heading (family, budget, or work meeting – whatever has cropped up) then the next step – call Laura’s teacher, write a list of outgoings, or email Sally. When you do this, you’re telling the brain, “We captured it. We’ll address it in daylight.”

If you’ve slept badly, naps are tempting. They can help, but long or late naps can push your bedtime later. Use them carefully, and try to limit them to 30 minutes in the early afternoon.

A practical 2 week reset plan

It’s common for sleep to be off for a week or two after a routine change. But consider extra help if your sleep problems last more than 3–4 weeks or if you’re regularly awake for long periods at night.

If your anxiety about sleep is growing, you feel your mood is dropping, you feel persistently on edge or your sleep issues are linked to panic symptoms, trauma, or intense stress, mental health support can help.

Counselling can be especially helpful when sleep difficulties are driven by stress, perfectionism, overthinking, relationship strain, or life transitions.

Working with unhelpful patterns driven by perfectionist, or people-pleasing mindsets, like late-night working or overcommitting can help reduce distractions so you can switch off.

We can equip you with nervous system regulation skills that you can use when you’re worried about sleep, late at night, and we can help soothe the sleep worry loop - if I don’t sleep, I can’t cope.

We hold a protected space for you to explore the emotional difficulties that arise when life finally goes quiet at night.

Sometimes, a combination of counselling and naturopathy can be the most effective route—because sleep sits at the intersection of biology, behaviour, and emotional wellbeing.

If your sleep feels messy after the holidays, it doesn’t mean you’ve “lost your ability” to sleep. Your body clock has shifted and your nervous system is still in high gear. A reset is usually less about discipline and more about steady signals: a consistent wake-up time, morning light, a workable wind-down buffer, and a kinder way of responding to nighttime worry.

Start small and stay consistent for 1 to 2 weeks. Sleep tends to return gradually, often in a few noticeable steps rather than one perfect night. And if it doesn’t, that’s not a personal failure. It’s simply a sign that your system may need extra support, and you don’t have to figure it out alone.
