You’ve wrapped up work, the evening is yours, and yet your brain hasn’t got the memo. You’re tired but wired. Sound familiar?
This is one of the most common complaints I hear from clients, and honestly, it makes complete sense. Modern life doesn’t come with a natural off switch. The same nervous system that kept you sharp, reactive, and on all day doesn’t just stand down because you closed your laptop. You have to actively create the conditions for it to shift gears.
Here’s what the science says, and what actually works in practice.
Your body wants to wind down. You just have to stop fighting it.
Your circadian rhythm, your internal body clock, is constantly reading environmental cues to figure out whether it’s time to be alert or time to rest. As the evening progresses, your brain is primed to start releasing melatonin, the hormone that signals sleep is approaching. But that process is easily hijacked by bright light, stress, stimulating content, and late-night eating.
A consistent wind-down routine helps lower cortisol, the stress hormone, and supports that natural melatonin release, which translates to falling asleep more easily and waking less during the night.
The goal isn’t to force sleep. It’s to stop working against your own biology.
Start earlier than you think
Most people try to wind down in the five minutes between the sofa and their pillow. That’s not enough runway.
Most people benefit from starting their wind-down routine around 30 to 60 minutes before their intended bedtime. Think of it less as a bedtime ritual and more as a slow deceleration, like easing off the accelerator well before a corner rather than braking hard at the last second.
Dim the lights, literally
Your internal clock is regulated by light. Bright overhead lights in the evening can interfere with melatonin production just as much as blue light from screens. Once evening approaches, switching to lamps with warmer, orange-toned bulbs makes a real difference.
This is such a simple, zero-effort change and most people never make it. Try it tonight.
A warm shower or bath is not just pampering
Research shows that bathing in warm water before bed is associated with significantly shorter time to fall asleep. The mechanism is interesting: warm water elevates your core body temperature, and then as you cool down afterwards, your body mimics the natural temperature drop that accompanies sleep onset. The ideal temperature is around 40 to 43°C, taken about 90 minutes before bed.
If a bath isn’t your thing, a warm shower works on the same principle.
Move your body, but keep it gentle
An evening walk is one of my favourite recommendations for clients who struggle to decompress after work.
Walking at a leisurely pace can help relieve stress and rumination, partly through the release of serotonin, which is a precursor to melatonin. You’re not trying to get a training effect here. You’re giving your nervous system permission to downshift.
Get your to-do list out of your head
If you lie awake running through tomorrow’s mental checklist, this one is for you. Spending a few minutes before bed writing down your thoughts, unfinished tasks, or plans for the next day is genuinely useful, not just anecdotally but neurologically. It externalises the load your working memory is carrying, so your brain isn’t trying to hold onto it while you sleep.
Nighttime rumination, known in neuroscience as pre-sleep cognitive activity, has been shown to delay sleep onset and contribute to insomnia. A journal or even a simple notepad is a surprisingly effective tool against it.
Watch what goes in the last few hours
Alcohol is a common wind-down choice, but the science doesn’t support it. While alcohol can make you feel relaxed initially, it disrupts REM sleep once its effects wear off, and can cause you to wake repeatedly during the night.
Caffeine is the other one worth tracking. The effects of an afternoon coffee last much longer than most people assume. For many people, anything after 2pm is affecting sleep quality, even if they feel fine falling asleep.
If you want something warm in the evening, herbal tea is a genuinely useful swap. One study found that chamomile reduced time to fall asleep by 16 minutes, and certain herbal teas contain compounds that have a meaningful relationship with sleep onset.
Keep your room cool
Your body needs to drop its core temperature by around 1 to 2 degrees Celsius to initiate and maintain sleep. The optimal bedroom temperature is around 18°C. Most New Zealanders sleep warmer than this, particularly in summer. Even cracking a window or using a fan can make a noticeable difference to sleep depth.
The habit is the point
None of these things work in isolation as a one-off fix. What works is consistency. When you repeat the same sequence of low-stimulus activities in the same order each evening, your nervous system starts to associate them with sleep. Think of it like training a muscle: the more you practise engaging your rest-and-digest system in the evening, the easier it becomes for your body to generate that same response at night. Oura
That’s behaviour change in action. You’re not just forming a habit, you’re rewiring a conditioned response.
Where to start
If you’re currently doing none of this, don’t try to overhaul your entire evening at once. Pick one change, run it consistently for a week, and notice what shifts. I’d suggest starting with the lights. It costs nothing, takes no extra time, and it works.
If sleep is a persistent issue for you, or you want to look at what’s actually driving your fatigue patterns, it’s worth having a proper conversation about it.
