From All-Nighters to 9pm Bedtimes - How Sleep Changes as You Age

Rest deeper. Wake fresher. Live better.

You’re 21, it’s 2am, and you're wide awake scrolling. Ten years later, you’re in bed by 9:30pm - and still wake up tired!

What happened?

Sleep evolves as we age, and understanding the shifts can help you sleep better now and set yourself up for the future.

Let’s break down what sleep looks like in each life stage, why it changes, and what you can do to get the most out of your nights (no matter your age).

In Your Late Teens: Sleepy But Stubborn

Teens and young adults actually need more sleep than most other age groups - up to 9 hours a night. But thanks to school, exams, part-time jobs, phones, and social pressure… they rarely get it.

• Body clocks naturally shift later (wanting to sleep and wake later)

• Most early wake-ups = running on sleep debt

• Screens, stress, and social life can totally wreck routine

- Sleep better tip: Set a wind-down time (even just 30 mins tech-free). Your brain’s still developing - treat it to some proper rest.

In Your 20s: All-Nighters, Sleep FOMO & Burnout

You’re juggling uni, early jobs, nights out, and a possibly tragic mattress. Sleep takes a back seat.

• Irregular sleep patterns are common

• Stress + caffeine = not a great combo

• Recovery is still fast... for now

- Sleep better tip: Sleep isn’t a luxury, it’s a life skill. Your future self will thank you for cutting the late scrolling and investing in decent bedding.

- In Your 30s: Busy Brain, Poor Boundaries

Career? Kids? Chaos? This is the decade where sleep starts to suffer, but you finally start to notice it.

• Cortisol (stress hormone) gets in the way of falling asleep

• You’re more sensitive to sleep loss

• Sleep debt builds and starts to hit harder

- Sleep better tip: Routine is everything. Same sleep + wake times every day (even weekends) help your body reset. Get outside in the morning, avoid caffeine after lunch.

In Your 40s: Hormones & Light Sleep

Sleep starts feeling… lighter. You might wake more during the night or struggle to fall asleep. Hormonal changes (especially for women) can also make sleep feel unpredictable.

• Hot flashes, anxiety, or joint pain may show up

• Your deep sleep time shortens

• You might go to bed earlier - and still wake tired

- Sleep better tip: Focus on sleep quality, not just quantity. Cool, dark bedrooms, supportive mattresses, and gentle exercise in the day can work wonders.

In Your 50s & Beyond: More Wake-Ups, But Sleep Still Matters

You might think poor sleep is “just how it is now” — but it doesn’t have to be.

• Sleep gets lighter, but still essential

• More frequent waking due to aches, bladder, or health conditions

• Less REM = less dreaming, more fatigue

- Sleep better tip: Upgrade your bedroom for comfort. Think: pressure-relieving mattress, blackout curtains, and calming evening habits.

So… Can You Sleep Well at Any Age?

Absolutely. The key is recognising your current sleep needs and adjusting how you support them. That might mean:

• Tracking your sleep patterns (use our free tracker!)

• Trying white noise or guided sleep meditations

• Swapping heavy duvets for lighter ones in summer

• Being honest about what’s stealing your sleep time (👀 late-night TikToks)

Because one thing doesn’t change: Sleep is essential at every stage.

Rest deeper. Wake fresher. Live better.
