Sleep became a serious interest of mine the moment I became a parent. Before kids, I slept well and took it for granted. After kids — and especially after the second one — sleep became this precious, fragile thing that I had to actively protect. Over years of coaching parents and obsessing over the research, I’ve narrowed it down to seven things that actually move the needle.
1. Consistent Sleep and Wake Times
This is the foundation. Your circadian rhythm is essentially an internal clock — and like any clock, it works best when it’s set to a consistent time. Aim to go to bed and wake up within a 30-minute window of the same time, most nights. I know that’s hard with kids. But even approximate consistency makes a significant difference to how rested you feel and how quickly you fall asleep. The science on shift workers is clear: irregular sleep schedules are linked to higher rates of anxiety, depression and metabolic dysfunction. Consistency is your first and most powerful lever.
2. Get Outside in the Morning
Natural light in the first 30 to 60 minutes after waking is one of the most powerful things you can do for your sleep that night. It signals to your brain that the day has begun, sets your cortisol curve correctly, and anchors your circadian rhythm. It doesn’t need to be long — even five minutes outside with a coffee counts. This single habit has made a noticeable difference to how alert I feel in the morning and how easily I fall asleep at night.
3. Protect the Hour Before Bed
The hour before you sleep sets the tone for the whole night. Screens off — or at least blue light filtered. No intense work or difficult conversations if you can avoid them. Nothing that spikes your heart rate or your cortisol. This is wind-down time. I read, I do some light stretching, sometimes I journal. The brain needs a transition period between the demands of the day and sleep. Don’t go straight from scrolling to trying to sleep and wonder why it takes an hour to switch off.
4. Keep Your Room Cool and Dark
Your body temperature needs to drop slightly to initiate sleep. A warm room fights against that. I keep my room on the cool side — around 18 degrees if possible. Blackout curtains or a sleep mask make a bigger difference than most people expect, especially in summer when it’s light until 9pm. These are small environmental adjustments with a disproportionate impact on sleep quality.
5. Watch the Caffeine Cutoff
Caffeine has a half-life of roughly five to six hours in the body. That afternoon coffee at 3pm? Half of it is still in your system at 9pm. I cut off caffeine by 1pm, sometimes midday if I know I have an early start. It sounds like a sacrifice, but once you adjust, you’ll sleep so much better that you won’t miss it. The morning cup hits differently too when your body isn’t still fighting yesterday’s afternoon espresso.
6. Move Your Body During the Day
Exercise improves sleep quality significantly — not by wearing you out, but by reducing stress hormones, regulating blood sugar and increasing the drive for deep sleep. You don’t need to train hard every day. A 30-minute walk plus some resistance training a few times a week is enough to notice the difference. What doesn’t help: intense training within two hours of sleep, which can elevate cortisol and delay sleep onset.
7. Accept That Some Nights Will Be Bad
This one is especially for parents of young kids: some nights, no amount of optimisation is going to save you. Your toddler gets sick, or the baby decides 3am is playtime. Accept it. Don’t catastrophise. One bad night doesn’t break your health. The anxiety about not sleeping is often worse for you than the lost sleep itself. Do your best, protect the habits on the nights you can, and give yourself grace on the nights you can’t.
