How to Sleep Better in Late Pregnancy

If you’re lying in bed feeling wiped out but your brain (and body) won’t fully shut off, you’re not alone. Late pregnancy can throw sleep off in a bunch of annoying ways—pressure, discomfort, reflux, and even bathroom trips. The good news is that you can often get real improvement by adjusting how you lie, setting up your pillows, and tweaking a few evening habits to be more sleep-friendly. Here’s a practical plan you can start tonight.

Sleep problems in late pregnancy: why you’re tired but can’t sleep

A lot of people describe late pregnancy sleep like this: you feel tired all day, but when bedtime comes, it takes forever to fall asleep—or you wake up a lot and can’t get back down.

Common causes of poor sleep during pregnancy include:

• Discomfort that changes as you move (hips, back, belly pressure, or just not finding a “right” spot)
• Needing to pee more often, especially if you’ve had more to drink later in the day
• Your sleep setup not matching your body now (what worked earlier in pregnancy may not work when you’re bigger and more tender)
• A bedtime routine that doesn’t wind you down—if you don’t calm down, your body stays on “go”

That’s why it can help to focus on things like sleeping on your side (especially your left side), using supports that match your body, and making your sleep space calmer. It’s less about forcing yourself to sleep and more about helping your body relax.

If you’ve been hit with insomnia at 33 weeks pregnant, try not to overthink it. Late pregnancy sleep can shift from week to week. Tonight’s job is to build a better setup, not fix everything at once.

Best sleep position in late pregnancy (side sleeping and left-side support)

When people say “sleep on your side” during late pregnancy, it’s not random advice. Sleeping on your side (especially your left side) matters. Side sleeping can help you feel more supported and can make it easier to stay comfortable through the night.

Here’s how to make it work in real life:

Try this tonight: locked-in side sleeping

• Lie on your side.
• If you can, aim for left-side support.
• Add pillows where your body naturally wants support:
• one between your knees (to help keep your hips aligned)
• one to support your belly
• one to keep your upper body from twisting

If you keep rolling onto your back or your other side, don’t treat it like failure. That’s common. Use your pillows to help guide you back into the position that feels best.

Pillow setup that helps: body pillows, wedges, and U-shaped options

Pillows can sound like extra work—until you feel how much they change things. The goal is simple: reduce strain and keep your body in one comfortable position for longer.

You can use a few common options:

• Body pillow or wedge for support

A body pillow or wedge can help hold your torso and hips so you’re not constantly repositioning.

• U-shaped pregnancy pillow

Many people like this because it provides support all around. One common setup is a U-shaped pregnancy pillow with your head propped up on two pillows.

• Propped head

If you feel worse when you’re flat, keeping your head and upper chest slightly raised can help you settle.

Pillow setup checklist (copy this and use it tonight)

When you’re in bed, take 30 seconds and check:

• Head: propped comfortably (many people use two pillows)
• Torso: supported so you’re not sinking or twisting
• Belly: supported so you’re not crunching forward
• Knees: one pillow between your knees
• Hips: stable, not sliding

If you use a body pillow, think of it like something you can hug. If you use a wedge, position it so you get gentle support, not a sharp angle.

Bedroom changes for better sleep: cool, dark, quiet, breathable bedding

Even with good positioning, your room can still make sleep harder. Late pregnancy sleep often improves fast when your bedroom supports your body’s “rest mode.”

Try these environment tweaks:

• Keep your room cool
• Make it dark (lights and glowing screens can keep your brain awake)
• Keep it quiet (or use steady background sound if silence makes you too aware of every little thing)
• Use breathable, cotton sheets and pajamas

Breathable fabric matters more than you’d think. If you run warm at night (many people do in late pregnancy), the right material can help you stay comfortable without waking up as much.

Quick “reset” before bed

If you can, do a small reset each night:

• dim the lights 30–60 minutes before you plan to sleep
• put your phone somewhere you don’t need to reach for
• keep the room cooler if you’re able

Evening routine fixes: wind-down before bed (including warm bath ideas)

If you’re lying there thinking, “I’m so tired… why can’t I sleep?” your next step usually isn’t trying harder. It’s about winding down before bedtime so your body isn’t still carrying the day’s stress.

A steady routine can also help when sleep in the third trimester feels unpredictable.

Try this tonight: a simple wind-down routine

Pick one calming routine and repeat it most nights:

• Set a regular bedtime as much as you can
• Wind down before bedtime with something gentle
• If you like baths: try a warm bath as part of the wind-down
• Keep it quiet and low-stimulation (dim lights, calm activities)

Consistency is the point. Your body learns the pattern: “This is when we slow down.”

One more small trick: if you’ve done everything right and you’re still wired, skip doom-scrolling. Choose something soothing in low light, then try again once your brain feels calmer.

Hydration and bathroom strategy: limit fluids late in the day

Waking up to pee is one of the most common reasons late pregnancy sleep gets cut up.

The habit to try: limit fluids late in the day to reduce bathroom trips. Stay hydrated earlier, then ease up later so you’re less likely to need to get up all night.

A practical approach (no guessing)

• Drink most of your fluids earlier in the day.
• Scale back in the evening, especially close to bedtime.

If your healthcare provider has told you to drink more for any reason, follow their guidance. But if the problem is waking up all night to pee, this is often the easiest change to try first.

Natural remedies for insomnia during pregnancy (non-medication options)

If you’re looking for natural remedies for insomnia during pregnancy, focus on changes that help your body settle rather than trying to force sleep.

These tend to work well for a lot of people in late pregnancy:

Non-medication options to try

• A regular bedtime (even if it isn’t perfect every night)
• A dark, cool, peaceful sleep environment
• Wind down before bedtime, like a calming routine
• A warm bath as part of your wind-down (many people find it relaxing)
• Limit fluids late in the day to reduce bathroom wake-ups
• Use the right support with side sleeping and pillows so discomfort doesn’t keep you from staying asleep

A big “natural” win is also removing friction. If you’re constantly shifting because you feel uncomfortable, you’re training your brain to stay alert. Solid pillow support can interrupt that pattern.

When “can’t sleep” might be a labor sign: 37 weeks pregnant can t sleep

Sometimes sleep problems come with normal pregnancy discomfort. Other times, symptoms can point to something else—especially as you get closer to your due date.

If you’re dealing with 37 weeks pregnant can’t sleep, it may still be normal insomnia. Still, it’s smart to watch for labor-related signs.

Consider contacting your clinician if you have symptoms that could suggest labor

If you also notice things like:

• regular, painful contractions that keep coming
• cramping that builds and doesn’t ease up
• any vaginal bleeding
• leaking fluid (like your water breaking)
• a big change in how baby is moving (especially if you notice a concerning decrease)

When you’re unsure, calling is okay. Checking can give you reassurance instead of wondering all night.

Also, if your insomnia is severe or you’re not sleeping much at all, reach out to a clinician. You deserve support, not just tips you hope will work this time.

Build a simple nightly plan for the next 7 days

Here’s a “tonight plan” that brings it all together—position, pillows, room setup, wind-down, and the bathroom/fluids strategy.

Tonight (Day 1): set up your sleep base

1) Sleep position

• Side sleep, aim for left-side support

2) Pillow setup (checklist)

• Head propped on two pillows (or whatever feels comfortable)
• Body supported with a body pillow or wedge
• Belly supported
• One pillow between your knees

3) Room

• Cool
• Dark
• Quiet
• Breathable cotton sheets and pajamas

4) Evening routine

• Start winding down before bed
• Try a warm bath or a calming routine in low light

5) Bathroom/fluids

• Hydrate earlier in the day
• Limit fluids late in the day to help reduce night trips

Days 2–7: repeat, tweak, and track one thing

Each night, repeat the core steps:

• Same bedtime window (as close as you can)
• Same wind-down routine
• Same side-sleep setup and pillow support
• Same room settings (cool/dark/quiet plus breathable bedding)
• Same “less fluid late” habit

Then pick one small adjustment based on what’s happening:

• If you’re waking up uncomfortable → adjust pillow support, especially knees/belly
• If you’re waking up to pee → reduce fluids a bit earlier
• If you can’t switch your brain off → start your wind-down a little earlier and keep lights low and the room quiet

The 7-day checklist you can share

Copy this for your phone notes and, if you can, bring a support person into it. Having someone cheer you on helps.

• [ ] Side sleeping, aim left support
• [ ] Pillow setup: head propped, belly supported, knee pillow in place
• [ ] Use body pillow/wedge or U-shaped support as planned
• [ ] Room cool + dark + quiet
• [ ] Breathable cotton sheets/pajamas
• [ ] Wind down before bed (warm bath or calming routine)
• [ ] Limit fluids late in the day (earlier hydration, easier nights)
