Sleep hygiene sounds clinical but it simply means the habits and environment that help you get consistently good sleep. Get it right and the difference to how you feel, function and cope with daily life is significant. Get it wrong and everything else becomes harder - concentration, mood, energy, even appetite.

I'll be honest - my sleep routine isn't perfect. I work late most evenings and I almost always watch at least one episode of a series before bed to switch my brain off from work mode. But over the years I've figured out what makes a real difference for me, and what's just noise. Here's what genuinely helps.

Get morning sunlight as early as possible

One of the most effective things you can do for your sleep is also the simplest - get natural light into your eyes within an hour of waking up. Morning sunlight helps set your circadian rhythm, the internal body clock that tells you when to be alert and when to wind down. When it's working properly, you feel naturally tired at the right time in the evening.

Even on a cloudy day, outdoor light is far brighter than indoor lighting and sends a clear signal to your brain that the day has started. A short walk, sitting by a window, or simply spending a few minutes outside first thing makes a difference you can actually feel over time.

Exercise - but not too close to bedtime

Regular exercise is one of the best things you can do for sleep quality. It reduces stress hormones, helps regulate your body temperature, and tires your body out in the right way. But timing matters.

Exercising too late in the evening - particularly anything intense - raises your heart rate and body temperature at a time when both need to be falling for sleep to come easily. Aim to finish any vigorous exercise at least two to three hours before bed. A gentle evening walk is fine and can actually help you wind down, but a gym session at 9pm is likely to push your sleep back.

Keep a consistent bedtime - even at weekends

This one is harder than it sounds but it makes a bigger difference than almost anything else. Going to bed and waking up at roughly the same time every day - including weekends and holidays - keeps your body clock stable and makes falling asleep much easier.

The temptation to stay up late on Friday and Saturday and sleep in on Sunday is understandable, but it effectively gives yourself social jetlag every week - disrupting the rhythm you've spent five days building. If you're someone who struggles to fall asleep or wakes up tired despite enough hours in bed, inconsistent sleep timing is often the culprit.

Create a wind-down routine

Your brain needs signals that sleep is approaching. A consistent pre-bed routine - even a short one - acts as those signals, gradually shifting your mind and body into sleep mode.

Mine involves getting into pyjamas, brushing teeth, sometimes a shower, and then watching one episode of a series in bed. Some sleep experts would say screens before bed are a bad idea, and in principle they're right - but for me, the switch from work to a show I enjoy is what finally turns off the work part of my brain. A calm, enjoyable episode of something I'm not too invested in works better for me than lying in the dark with a busy mind. You know yourself - find what genuinely winds you down rather than following advice that doesn't fit your life.

Other good wind-down options include reading, a warm bath or shower, gentle stretching, or simply sitting quietly without a screen. The key is consistency - doing the same things in the same order tells your brain what's coming next.

Use an orange or warm light in the evening

Bright white or blue-toned light in the evening suppresses melatonin production - the hormone that makes you feel sleepy. Switching to warmer, dimmer lighting in the hour or two before bed makes a noticeable difference.

I use an orange glow night light in the evenings rather than overhead lighting, which creates a much more relaxing atmosphere and genuinely seems to help with feeling ready for sleep at the right time. Most phones and screens now have a night mode that shifts the display towards warmer tones - worth switching on if you use your phone in the evenings.

Keep your bedroom cool, dark and comfortable

Your body temperature naturally drops as you fall asleep, so a cool room helps the process along. A stuffy or too-warm bedroom makes sleep harder to initiate and easier to disturb. We sleep with the window open when possible and keep the bedroom cooler than the rest of the house.

Blackout blinds make a significant difference, particularly in summer when it's light early. Even small amounts of light can disrupt sleep quality without you being consciously aware of it. If blackout blinds aren't possible, a good sleep mask does a similar job.

Space also matters. We have a king size bed and the room to move without disturbing each other, which genuinely helps when you have different sleep patterns or one person is a restless sleeper. It's not always possible but if you're sharing a bed a larger mattress is worth prioritising.

Invest in quality bedding - it genuinely matters

I've had cheap bedding and I've had good bedding and the difference is real. I currently use Simba bedding and Dorma feather-like pillows and the quality of sleep is noticeably better than when I was using cheaper alternatives.

My husband prefers Simba pillows while I prefer the Dorma feather-like ones - it's worth finding what works for you personally rather than assuming everyone needs the same thing. Side sleepers, back sleepers and front sleepers all benefit from different pillow heights and firmness levels.

A few habits that extend the life of your bedding and keep it comfortable longer - fluff pillows up regularly to help them keep their shape, and flip or rotate your mattress as the manufacturer recommends to prevent it from sinking unevenly. A mattress that's lost its support does far more damage to sleep quality than most people realise.

Watch what you eat and drink before bed

Eating a heavy meal close to bedtime makes it harder to fall asleep and more likely that you'll wake in the night as digestion kicks in. Try to finish eating at least two to three hours before you go to bed, and keep evening meals on the lighter side where possible.

Alcohol is worth mentioning because it's widely misunderstood as a sleep aid. It might help you fall asleep faster but it significantly disrupts sleep quality in the second half of the night, reducing REM sleep and causing earlier waking. The occasional drink isn't a problem but regular evening alcohol reliably makes sleep worse overall.

Caffeine has a half-life of around five to six hours, which means a coffee at 4pm still has half its caffeine in your system at 10pm. Switching to decaf or herbal tea after mid-afternoon is one of the easiest and most effective sleep improvements you can make.

Reducing fluids in the two hours before bed also helps avoid waking in the night for the bathroom - particularly relevant if that's a pattern you recognise.

Make your bedroom a calm, relaxing space

The environment you sleep in affects how quickly you fall asleep and how well you stay asleep. A cluttered, untidy room creates a low-level sense of unease that can be surprisingly disruptive. Keeping the bedroom calm and uncluttered - even if the rest of the house is chaos - creates a genuine sense of sanctuary.

Temperature, noise, light and comfort all matter, but so does the psychological association you have with the space. If your bedroom is where you work, watch stressful news, argue, or lie awake worrying, your brain starts to associate it with wakefulness rather than sleep. Keeping it as a space primarily for sleep and relaxation strengthens that association over time.

What to do if you can't sleep

If you get into bed and can't sleep after around 20 minutes, lying there willing yourself to sleep usually makes things worse. Getting up, going to a different room, doing something calm in dim light, and returning when you feel genuinely sleepy is more effective than forcing it.

Stress and anxiety are the most common causes of difficulty falling asleep. A brain that won't stop is one of the most frustrating sleep obstacles. Writing down whatever is on your mind before bed - a to-do list, worries, thoughts - can help empty it enough to let sleep come. 10 free and simple ways to beat stress covers more practical approaches to managing the kind of stress that keeps you awake.
