March 13th is World Sleep Day, a timely reminder that better sleep isn’t about chasing perfection – it’s about small, evidence-based habits that help your body and mind unwind. Here are seven practical tips, backed by research, to help you sleep more soundly tonight .

Most of us know that sleep is essential for our wellbeing, but when life is busy, good sleep can feel frustratingly out of reach. The encouraging news is that sleep responds well to small, consistent changes. Research from Massey University’s Sleep/Wake Research Centre shows that even modest improvements to sleep habits can support mood, immunity and overall health .

Below are seven evidence-based habits that sleep specialists consistently recommend – practical steps you can start using straight away.

1. Keep a consistent sleep schedule

Our bodies rely on a predictable internal clock, or circadian rhythm, to signal when it’s time to sleep and wake. Going to bed and getting up at roughly the same time each day strengthens this rhythm, making it easier to fall asleep and wake feeling refreshed. Irregular sleep schedules disrupt the release of melatonin – the hormone that tells your body it’s time to sleep – and can make sleep lighter and more fragmented.

Your sleep schedule doesn’t need to be perfectly regimented – even keeping your wake-up time consistent can help anchor your sleep.

2. Reduce screen time in the hour before bed

Blue light from phones, tablets and laptop screens can suppress melatonin. Harvard researchers found that using light-emitting screens before bed delays sleep onset and reduces next-day alertness.

If avoiding screens entirely isn’t realistic, consider:

• Activating “night mode” on devices.
• Lowering screen brightness.
• Listening to music or podcasts instead of watching videos.

3. Create a cooler, darker bedroom

Temperature plays a major role in sleep quality. The ideal sleep environment is cool – typically around 15–19°C – because our core body temperature naturally drops at night.

Light is another factor. Even dim light during sleep has been linked to increased nighttime awakenings.

Simple changes help, like:

• Blackout curtains
• Turning off hallway lights
• Switching bright digital clocks or chargers to a dimmer setting.

Think of your bedroom as a calm, low-light environment that signals to your body that it’s time for rest .

4. Be mindful with caffeine – especially in the afternoon

Caffeine blocks adenosine, a chemical that helps us feel sleepy. Even six hours after consuming caffeine, sleep duration and sleep quality can be significantly reduced .

Practical takeaways:

• If you enjoy coffee, try limiting it to the morning.
• Switch to herbal tea or decaf in the afternoon.
• Keep in mind that chocolate, soft drinks and energy drinks can have more caffeine than expected.

Caffeine sensitivity varies, but reducing it after midday is a reliable way to improve sleep.

5. Build a wind-down routine your body recognises

Sleep researchers emphasise that adults benefit from consistent bedtime routines just as much as children. A consistent pre-sleep pattern trains your brain to shift from active to restful states.

Relaxation techniques such as slow breathing, light stretching, reading or journalling can reduce sleep-onset delay.

Ideas to try:

• 10 minutes of gentle stretching
• A warm shower
• Switching to low lighting
• Writing down tomorrow’s tasks to reduce mental “clutter”

6. Get natural light early in the day

Morning light is one of the strongest ways to reset your circadian rhythm. Exposure to sunlight in the first hour or two after waking helps regulate melatonin and supports more stable sleep-wake cycles. Recent research suggests it can also shield you from some of the downsides of artificial light at night, which can otherwise interfere with good sleep .

You don’t need to sunbathe – a short walk outside or enjoying a coffee near a bright window is enough to help your system stay aligned with natural day-night patterns.

7. Address stress and overthinking before you get to bedtime

It’s common for busy minds to become even busier at night. Stress and rumination activate the brain’s alertness pathways, making it harder to fall asleep.

Helpful strategies include:

• “Worry time” earlier in the day: Set aside 10 minutes to jot down concerns, so they’re less likely to reappear at night.
• Mindfulness techniques: Meditation and other mindfulness techniques can improve sleep quality in adults by reducing pre-sleep arousal .
• Talking to your GP if stress, anxiety or low mood are becoming persistent.

What if you’ve tried all this and still struggle to sleep?

If sleep difficulties are affecting your daytime functioning or lasting longer than a few weeks, it’s worth speaking with your GP. Persistent insomnia, loud snoring, gasping during sleep or ongoing daytime fatigue can be signs of underlying sleep disorders.

Better sleep starts with small, manageable steps

Different people can have different sleep needs, so try not to worry that you’re not getting enough sleep, because that can make things worse. Trust your body to take as much sleep as it needs by giving it a chance using these steps.

Improving your sleep doesn’t require an overhaul of your entire life. A few simple habits – like cooling your bedroom, stepping outside into morning light, reducing caffeine after midday or putting devices aside before bed – can have a meaningful impact.

As we mark World Sleep Day, consider choosing one or two habits to start with. Over time, these gentle adjustments can help your body find its natural rhythm again, supporting better energy, mood and wellbeing each day. As always, please see a healthcare professional if poor sleep is negatively impacting your daily life.
