If your favourite shoes have started feeling tight, or your lower legs are heavy and throbbing by 4pm, you have met one of pregnancy's most common rites of passage.
Swelling in the ankles, feet and fingers is a normal part of pregnancy. As Pregnancy, Birth and Baby explains, it tends to be worse towards the end of the day and usually settles overnight, which is exactly why the timing of when you wear compression socks makes such a difference.
If you have just picked up your first pair, the practical question follows quickly: how many hours a day should you actually wear them, and when should they come off?
Here is how to build a daily routine that keeps your legs feeling lighter.
(This guide covers the daily wear schedule. If you are still working out which size to buy, start with our compression sock size guide, then come back here.)

The Short Answer
For most healthy pregnancies, the general approach is straightforward: wear them through your active daytime hours, and take them off before bed.
Why Morning Is the Right Time to Put Them On
It is much easier to stay ahead of swelling than to catch up with it once your ankles have already puffed up.
Overnight, lying flat, fluid redistributes and your ankles and feet are at their slimmest first thing. Putting your socks on before you have been upright for long means the graduated profile is working from the start of the day, rather than being pulled over an already-swollen leg.
Why They Come Off at Night
Unless your midwife or doctor has specifically advised otherwise for a particular condition, you do not need to wear compression socks to bed.
Lying flat, your legs are level with your heart, so gravity isn't drawing fluid down into your feet the way it does when you are upright. The socks simply aren't doing much at that point, and your skin appreciates the break.
How Many Hours Is Ideal?
There is no strict timer. Most women wear theirs for 8 to 12 hours a day, which usually just means the length of their normal waking routine.
Matching Your Hours to Your Day
-
Desk work and long sitting: hours in an office chair with your knees bent slows circulation in your lower legs. Wearing them across a standard workday helps head off that heavy 5pm feeling.
-
Standing shifts and active days: teachers, retail and healthcare workers, and anyone chasing a toddler are on their feet for long stretches. Wearing them through those active hours supports your calf muscles and reduces foot fatigue.
-
Travel and flying: the Better Health Channel notes that long journeys involving more than four hours of sitting are associated with sluggish blood flow, so compression socks are a sensible choice on flights and long drives. If you are pregnant and planning a long-haul trip, it is worth mentioning to your midwife beforehand.
-
Light exercise: wearing them for a walk or a Pilates session helps with leg stability, and many women keep them on for an hour or two afterwards.

A Quick Word on Compression Levels
Compression is measured in millimetres of mercury (mmHg), and the number affects how long the socks stay comfortable:
-
Light (8 to 15 mmHg): gentle, subtle support. Comfortable for long stretches, though many women find it isn't quite enough once pregnancy swelling really arrives.
-
Moderate (15 to 25 mmHg): the range most commonly recommended in pregnancy, and the one that suits an 8 to 12 hour day without feeling restrictive.
-
Higher pressure (30+ mmHg): these are prescribed by a doctor or specialist for specific vein conditions, with their own wear instructions. If you have been prescribed these, follow your provider's guidance rather than the general advice here.
Sleepybelly Maternity Compression Socks sit in that moderate range, ARTG-listed (ARTG 521641) with a 15 to 25 mmHg graduated profile in soft bamboo, which is what makes them wearable across a full day rather than something you are counting down to remove.
Evening Habits Once the Socks Are Off
Taking them off at 7pm doesn't mean your legs are on their own:
-
Elevate: prop your feet on a couple of pillows so they sit slightly above heart level while you are resting.
-
Soothe restless muscles: massaging Sleepybelly Magnesium Body Cream into your calves is something many women find calms that twitchy, restless feeling before bed.
-
Support your side-sleeping: a cushion like the Sleepybelly Pregnancy Pillow between your knees and ankles keeps your legs parallel and takes stress off your hips overnight.
-
Skip the tight waistbands: loose sleepwear with a soft waist, like the Sleepybelly 3-Piece Maternity Pyjamas, so nothing digs in while you sleep.

When to Check In With Your Midwife
Mild swelling in your feet and ankles is a normal part of carrying a baby. Sudden changes are worth a phone call.
Contact your doctor or midwife promptly if you notice:
-
Sudden or severe swelling in your hands, face, or around your eyes.
-
Swelling in one leg only, particularly with pain, redness, or warmth to the touch.
-
Swelling alongside headache, vision changes, or pain under your ribs.
Pregnancy Birth and Baby is clear that sudden swelling should be checked, since it can occasionally signal something that needs attention. If you would like a midwife's perspective on what is normal and what is worth flagging, Monique at The Middee Society shares clear, reassuring guidance on exactly these questions.
The Bottom Line
Wearing maternity compression socks for 8 to 12 hours across your active day is the approach most women land on. Put them on first thing before swelling builds, get on with your day, and take them off before bed so your legs can rest.

Frequently Asked Questions
Can I wear compression socks every day during pregnancy?
For most healthy pregnancies, yes. Many women wear them daily from the second trimester onward and continue for a few weeks postpartum. If you have a circulatory or skin condition, check with your midwife or GP first.
Is it okay to nap in them?
A short daytime nap of 30 to 60 minutes in your socks is generally fine. For a full night's sleep it is better to take them off, so your legs get a proper break from continuous pressure while you are lying flat.
How do I know if mine are too tight?
They should feel snug and supportive, like a firm hug around your calves, and never painful. Numbness, tingling, cold toes, or skin discolouration all mean the fit is wrong. Take them off and check your sizing, or speak with your midwife or GP.
