The Twenty-Something’s Guide to Better Sleep Hygiene

Sleep is something we all claim we want more of, but we rarely prioritize sleep hygiene. In your twenties, it feels almost normal to be constantly tired. Between work, side hustles, classes, relationships, travel, endless text threads, and also staying up way too late scrolling TikTok, sleep is usually the first thing to go. And somehow, even on the nights where you get eight hours, you still don’t wake up feeling fully rested.

Here’s the thing: your twenties are the perfect time to build habits that protect your long-term health, energy, mental clarity, as well as productivity. Sleep hygiene—meaning the habits and choices that support high-quality rest—isn’t just a wellness trend. That’s because it’s a foundation for every part of your life.

So, if you’re done relying on caffeine to function, or you’re tired of being tired, here’s your guide to better sleep hygiene and the small, simple shifts that make a huge difference.

Why Sleep Hygiene Matters More in Your Twenties Than You Think

Your twenties are a decade of growth. You’re designing your lifestyle, figuring out your career direction, building relationships, and also discovering what routines actually help you thrive. Sleep plays a major role in all of that.

Good sleep impacts:

• Memory and learning
• Decision-making
• Mood stability
• Creativity
• Stress regulation
• Metabolism and hormones
• Focus and productivity

Meanwhile, poor sleep makes everything feel harder. You’re more impatient, more emotional, more unfocused, and more likely to experience burnout. And unfortunately, chronic sleep deprivation often shows up silently—it becomes your “normal” until you finally get good rest and realize how bad things were.

Improving your sleep hygiene now is so important now because it gives you a lifelong advantage. These habits become second nature, helping you stay grounded as well as energized through every season of your twenties and beyond.

Tip #1: Reduce Blue Light (Especially Before Bed)

If you struggle to fall asleep, blue light may be partly to blame. Phones, tablets, laptops, as well as TVs emit blue wavelengths that trick your brain into thinking it’s daytime. That suppresses melatonin—the hormone that helps you feel sleepy.

Here are simple ways to cut down your nighttime blue light exposure:

• Set a “screens off” time: Aim for at least 30–60 minutes of screen-free wind-down time before bed. Remember, you don’t need to be perfect—just consistent.
• Use Night Mode or Blue Light Filters: Most devices have a built-in option to warm your screen tones in the evenings.
• Try blue light–blocking glasses: These can help if you’re working late or watching TV before bed.
• Replace scrolling with relaxing activities such as:
  • Light stretching
  • Reading a physical book
  • Journaling
  • A warm shower
  • Listening to a calming playlist or podcast

Your brain needs a clear signal that the day is ending, and reducing blue light gives it exactly that.

Tip #2: Set a Consistent Bedtime Routine for Better Sleep Hygiene

Bedtime routines aren’t just for kids—they’re one of the best ways to train your body to fall asleep faster and also sleep deeper.

A strong nighttime routine:

• Lowers stress
• Regulates your nervous system
• Helps your mind detach from the day
• Makes it easier to wake up refreshed

Here’s a simple routine you can customize:

1. Choose a realistic bedtime

• Not your “fantasy” 9:30 p.m. bedtime—your actual target. Aim for the same sleep and wake window every day (yes, weekends too, at least loosely).

2. Create a 20–30 minute wind-down sequence

This step of sleep hygiene can include:

• Washing your face and brushing your teeth
• Turning off bright overhead lights
• Doing 5–10 minutes of gentle stretching
• A warm shower
• Making tomorrow’s to-do list (so your brain stops running through it in bed)

3. Make your room a calming space

• Dim lighting, comfortable bedding, and a clutter-free environment all help your mind transition to rest.

4. Protect your routine

• Your bedtime routine should signal safety and predictability. The more consistent it is, the easier sleep becomes.

Tip #3: Upgrade Your Sleep Environment (And Yes, Your Mattress Matters)

We don’t talk about this enough: your mattress might be silently sabotaging your sleep. This brings up the important point that sleep hygiene is more than routine habits.

Most twenty-somethings are sleeping on:

• A hand-me-down mattress
• A mattress from college
• A worn-out spring mattress
• Something too soft, too firm, or too old

A bad mattress leads to restless nights, back pain, overheating, as well as micro-awakenings you don’t even notice—but your body definitely does.

What a good mattress should provide:

• Proper spinal alignment
• Pressure-point relief
• Cooling technology
• Motion isolation (great for couples or pets)
• Durability

When you sleep on something supportive, your body actually gets to relax. That means deeper rest, less tossing and turning, and then a smoother wake-up.

If your mattress is sagging, hurting your back, or older than seven years, upgrading is more than a comfort purchase—it’s a long-term investment in your health, focus, and energy.

One of the biggest, yet most overlooked, elements of good sleep hygiene is your mattress — the surface your body spends roughly a third of its life on! A supportive mattress helps your body relax fully overnight, keeps your spine aligned, and reduces tossing and turning that can disrupt sleep cycles.

Lull mattresses are designed with premium responsive memory foam that contours to your body while still providing enough support to keep your spine in a neutral position — a sweet spot for restful sleep no matter how you sleep.

Lull stands out in the mattress space for a couple of reasons:

• Pressure relief + support: Multi-layer foam construction cradles pressure points like hips and shoulders while keeping your spine aligned.
• Cooling comfort: Gel-infused memory foam and breathable covers help pull heat away from your body so you don’t overheat through the night.
• Motion isolation: If you sleep with a partner or pet, motion transfer is minimized so small shifts don’t wake you up.
• Trial + peace of mind: Lull offers a risk-free sleep trial and easy returns, making mattress upgrades feel less intimidating.

Choosing a mattress that actually supports you — rather than one that leaves you sore or hot every morning — is a simple yet powerful way to level up your sleep hygiene routine.

Tip #4: Protect Your Mornings to Improve Your Nights

This sounds backward, but your morning routine has a huge impact on your sleep quality. This means that your sleep hygiene starts in the mornings.

Get natural light ASAP

• Sunlight in the first hour you’re awake helps regulate your circadian rhythm and also boosts alertness.

Avoid immediately checking your phone

• Starting your day with stress, notifications, or chaos disrupts your mindset and in turn affects your sleep 12–16 hours later.

Eat a balanced breakfast

• Stable blood sugar levels improve energy throughout the day (as well as help you wind down more easily at night).

Move your body

• Even a 10–15 minute walk or stretch session helps regulate your internal clock.
• Good sleep starts first thing in the morning.

Tip #5: Create Boundaries With Work and Stress

Stress is one of the biggest reasons twenty-somethings struggle to sleep. Fortunately there are ways we combat these stressors with better sleep hygiene.

We often take our anxieties to bed with us:

• Work deadlines
• Text messages
• Money worries
• Life decisions
• Racing thoughts

To create separation between your daytime stress and your nighttime calm:

• Try a brain dump by writing down everything on your mind before you climb into bed.
• Set work cut-off times which include email, Slack, and “I’ll just send one more message.”
• Practice calming techniques:
  • Deep breathing
  • Progressive muscle relaxation
  • Meditation
  • Grounding exercises

Your mind needs space to decompress. Protect it fiercely as part of your better sleep hygiene.

Tip #6: Know When to Limit Caffeine, Heavy Meals, and Late-Night Drinks

Even if you can fall asleep after coffee, alcohol, or a big late dinner, your sleep quality still suffers.

These beverages can have unseen consequences:

• Caffeine: Affects not only your brain’s ability to shut down but other areas of your body too.
• Alcohol: Causes fragmented sleep and reduces REM (so you may sleep but not rest)
• Heavy meals: Can disrupt digestion and also keep your body awake internally

Try substituting with:

• Herbal tea
• Tart cherry juice
• Plenty of water throughout the day

Making the choice to stop having caffeinated drinks 6-8 hours before bedtime will also contribute to better sleep. You will find these small tweaks add up quickly.

The Long-Term Benefits of Better Sleep Hygiene

Once you start prioritizing your sleep consistently, you’ll notice:

• More stable energy
• Clearer thinking
• Better emotional regulation
• Improved skin
• Less stress
• Better productivity
• Stronger immune system
• Better workouts and recovery

Good sleep hygiene isn’t about perfection—it’s about consistency. A few small, sustainable habits create a powerful ripple effect.

Final Thoughts: Your Twenties Are the Perfect Time to Build Restful Routines

Sleep isn’t something you earn—it’s something your mind and body require in order to show up as your best self. In your twenties, when you’re laying the groundwork for who you want to become, the habits you build now will support you for decades.

Reducing blue light, setting a solid bedtime routine, and upgrading your mattress are simple, high-impact changes that pay off quickly and continue to benefit you long-term.

Your future self—the one who feels focused, energized, and grounded every morning—will thank you for starting today.
