There is a moment that almost nobody talks about out loud. The baby finally sleeps, the house is silent, and instead of relief a wave of crying arrives that you cannot explain. Or the opposite: your heart pounding at three in the morning, the need to check that they are breathing for the fifth time, your head spinning on thoughts you cannot stop.

If you are here, you are probably trying to understand two things: whether what you feel is normal, and whether moving a little would make you feel better.

Here is the honest answer straight away, then I will explain it with the numbers. Emotional distress after childbirth is very common. Movement does help, but only a little: the effects measured in studies are modest. And there is a range of situations in which movement has nothing to do with it and you need a mental health professional, now.

This article is written to hold these three things together without cheating on any of them.

How common it is to feel unwell after childbirth

The numbers matter because almost everyone thinks they are the only one. You are not.

The baby blues. This is the most common of all. A systematic review with meta-analysis of 26 studies and 5,667 women estimated a prevalence of 39% (95% CI: 32.3-45.6). Individual studies ranged from 13.7% to 76%: an enormous variability, which depends on how it is defined and when it is measured. It arrives in the first few days, makes you cry, makes you hypersensitive and irritable, and in most cases resolves on its own within a couple of weeks.

Postnatal depression. Here the numbers change a great deal depending on how you measure them, and it is important to know this. The estimates that circulate most often come from questionnaires filled in by the women themselves. A meta-analysis that included only studies with a genuine diagnostic interview, 54 studies and 15,586 women, found a prevalence of 12.1% (95% CI: 10.3-14.1) for any depressive condition within a year of childbirth, and 7.0% (95% CI: 5.7-8.4) for major depression. Roughly one woman in eight, and one in fifteen for the major forms. The same authors note that this estimate is lower than what is usually read, precisely because it is based on interviews and not on self-assessment.

One practical detail from that same analysis: the peaks fall in the first six months, and in particular around 2-3 weeks and 6-8 weeks. That is often after everyone has stopped asking how you are.

Anxiety. This is the most underestimated part. A Bayesian meta-analysis of 26 studies estimated that, between pregnancy and the postpartum period, the prevalence of at least one anxiety disorder is 20.7% (95% highest density interval: 16.7-25.4): one woman in five. Individual disorders ranged from 1.1% for post-traumatic stress disorder to 4.8% for specific phobia. The authors conclude that they are more common than assumed and should be actively looked for, not waited for.

Keep this in mind when someone tells you "it is just tiredness". Sometimes it is anxiety, and it has a name.

Baby blues or something more: the difference that matters

You do not need a diagnosis made at home. You need two questions.

How long does it last? The blues is a phase, not a state. If after two weeks you feel the same as before or worse, it is no longer the blues.

How much is it taking from you? The blues makes you cry but lets you function. When the distress starts to take away your ability to eat, sleep when you could, leave the house, look after the baby or feel anything for them, the picture has changed.

In perinatal health pathways, the most widely used tool for orientation is the EPDS (Edinburgh Postnatal Depression Scale). It is worth knowing how it works, because it is often misunderstood. A meta-analysis of individual data from 58 studies and 15,557 participants, published in the BMJ, measured its accuracy: the threshold that best balances sensitivity and specificity is 11 or more (sensitivity 0.81, specificity 0.88 against a semi-structured interview), while a threshold of 13 or more is less sensitive but more specific (0.66 and 0.95).

Translated: the EPDS is a filter, not a diagnosis. A high score means "this needs looking at closely by a doctor", not "you have depression". And a low score does not cancel out what you feel: if you are struggling, that number does not decide for you.

What the reviews on exercise really say

Now the part you came to read. And the part where most articles around the subject exaggerate.

The best source today is a systematic review with meta-analysis published in the British Journal of Sports Medicine in 2025, the one that fed the Canadian postpartum guideline. It included 35 studies and 4,072 women. Here is what it found for exercise-only interventions compared with no exercise:

Outcome Studies Women Measured effect How the authors describe it
Severity of depressive symptoms 19 RCTs 1,778 SMD -0.52 (95% CI: -0.80 to -0.24) moderate effect
Severity of anxiety symptoms 2 RCTs 513 SMD -0.25 (95% CI: -0.43 to -0.08) small effect
Probability of postpartum depression 4 RCTs 303 OR 0.55 (95% CI: 0.32 to 0.95) -45%

Three things need saying, and none of them is promotional.

The first: the effect on mood is real but of moderate size, with very high heterogeneity between studies (I² = 86%). This means individual studies do not agree much with each other.

The second: the anxiety result rests on just two randomised trials. Two. And it is a small effect. None of the included studies even measured whether exercise reduces the chance of developing an anxiety disorder: that data simply does not exist.

The third: the 45% reduction in the probability of postpartum depression comes from 4 studies with 303 women in total. It makes a striking headline but carries little weight.

Earlier reviews tell the same story in different tones. A 2017 meta-analysis in the British Journal of General Practice (13 randomised trials, 1,734 women) found a reduction in depressive symptoms with an SMD of -0.44 (95% CI: -0.75 to -0.12), but urged caution in interpreting it because of substantial heterogeneity and risk of bias. And a 2019 review in Archives of Women's Mental Health (18 randomised trials) concluded that the effects were small and the quality of the evidence low, suggesting that exercise may be an alternative route mainly to prevent major depression in women with depressive symptoms below the clinical threshold, which is a different thing from treating a depression already under way, and it should be said clearly.

One last useful piece of data to avoid false hopes. The 2026 update of the Cochrane review "Exercise for depression" (73 randomised trials, at least 4,985 participants) found, for exercise compared with no treatment, an SMD of -0.67, which dropped to -0.46 when considering only the seven studies with concealed allocation, intention-to-treat analysis and blinded assessors. In other words: the more rigorous the study, the smaller the effect. And note a detail that almost nobody reports: that Cochrane review explicitly excludes studies on postnatal depression. It is not a source on the postpartum period: it is a measure of how fragile the literature on exercise and mood is in general.

How much and what kind: the practical numbers

If you decide to try, these are the real reference points.

The dose. In the 2025 review, achieving at least a moderate reduction in the severity of depressive symptoms required at least 350 MET-minutes a week. The authors translate this as roughly 80 minutes a week of moderate-intensity activity: brisk walking, water aerobics, cycling, strength exercises. Eighty minutes spread over seven days is just over ten minutes a day. It is a low threshold, and it is the best news in the whole article.

Walking. It is the activity with the most direct evidence and the fewest practical obstacles, because you can do it with the pram. A meta-analysis of 5 randomised trials and 242 women, all with mild to moderate depression, found a mean reduction of 4.01 EPDS points compared with controls (95% CI: -7.18 to -0.84), with high heterogeneity. The same authors add, on the basis of a narrative count rather than a formal analysis, that the interventions that seemed to work best were walking only, supervised and in groups, between 90 and 120+ minutes a week.

The type of exercise. Here the evidence is soft. A 2026 network meta-analysis of 43 randomised trials and 3,843 women estimated that after childbirth mind-body activities (yoga, Pilates) worked better than the others, while among women already showing symptoms aerobic exercise appeared most effective. The credibility intervals, however, are very wide and the individual studies small: these are indications, not prescriptions. The useful version is that there is no right activity in the abstract: there is the one you can do with a newborn at home.

On the "how" and "where to begin", I am not starting from zero: the physical sequence for returning to movement (breathing, pelvic floor, progressive loading) is already covered in postnatal gym: where to really start, and the full picture of what happens to the body in the first weeks is in postnatal recovery: what really happens to the body.

The piece that is almost always missing: sleep

If you are reading this at two in the morning, this section is more relevant to you than the others.

A systematic review with meta-analysis from 2025, again in the BJSM and again feeding the Canadian guideline (60 studies, 20,684 women), measured the effect of sleep interventions in the first year after childbirth. With evidence certainty judged high, sleep interventions reduced the severity of depressive symptoms compared with no intervention (5 randomised trials, 992 women, SMD -0.27, 95% CI: -0.40 to -0.14): a small effect, but with methodological solidity higher than almost all the rest of the literature in this area.

The rest should also be said, and it is less encouraging: the same interventions did not change the probability of developing depression (moderate certainty), nor anxiety symptoms or the probability of anxiety (low certainty).

The practical sense is nonetheless clear: protecting sleep is not a luxury and not laziness. It is one of the few levers with decent evidence behind it. Before feeling guilty because you cannot find twenty minutes to move, ask yourself whether someone can take the baby while you sleep three hours in a row.

Why movement should not be called "a cure"

Let us put the pieces together.

A moderate effect on depressive symptoms. A small effect on anxiety, from two studies. A small effect of sleep. Evidence of low to moderate quality. No review that says exercise replaces therapy.

This is exactly the profile of an adjunct: something you add, not something that sets the rest aside. The 2025 Canadian guideline on physical activity, sedentary behaviour and sleep in the first year after childbirth, developed with GRADE methodology and drawing on seven systematic reviews, concludes that following those recommendations probably leads to large improvements in psychological wellbeing, as well as in pelvic, musculoskeletal and cardiometabolic health, and to less fatigue, with no adverse events (moderate certainty of evidence). Improved wellbeing: not curing an illness.

And there is one more reason to be careful. Presenting movement as the solution means handing a woman who is already unwell one more responsibility to fail at. If you cannot manage a twenty-minute walk because you have not slept and have been crying for three days, the problem is not your discipline: it is that what you probably need is something else.

On fatigue, which is almost always the number one complaint, there is one more finding: a 2024 meta-analysis of 37 studies found benefits of exercise on maternal depression, anxiety and fatigue, more marked in women treated after childbirth than during pregnancy. It should be read with caution, because it mixes prenatal and postnatal studies and has high heterogeneity, but it points in the same direction: moving a little tires you less than you think.

When it is not enough: the signs you should not wait on

This is the most important section of the article, and if you read only one thing, read this.

Ask for help now, today, if:

  • thoughts of harming yourself, or of harming the baby, cross your mind, even just as images that frighten you;
  • you can no longer look after yourself or the baby: eating, washing, responding to their needs;
  • you do not sleep at all even when the baby sleeps, and feel wired, euphoric or confused;
  • you hear or see things others do not perceive, or become convinced of things that your loved ones find absurd.

The last two points together describe postpartum psychosis: in the literature on postpartum psychiatric disorders it is described as rare but more serious than depression and anxiety, which are instead relatively common. It must be treated as an emergency: it is not a "let's see tomorrow" matter. Call 112 or go to the emergency room.

Book an appointment this week if:

  • more than two weeks have passed and your mood is not lifting, or is getting worse;
  • the anxiety stops you sleeping, eating or leaving the house;
  • you check the baby compulsively, or avoid being alone with them;
  • you feel nothing for the baby, or feel guilty constantly and out of proportion;
  • someone who cares about you has already told you that you seem different to them, and you brushed it off.

Concretely, who to turn to: your GP, the family counselling service (consultorio familiare), the birth centre where you gave birth, or directly a psychologist or psychiatrist with perinatal experience. The leading international review on postpartum psychiatric disorders lists as treatment goals reducing maternal symptoms and supporting the functioning of the mother-child relationship and of the family; the woman and her relatives should receive information about the condition and an evidence-based discussion of the risks and benefits of each possible treatment.

Asking for help takes nothing away from you as a mother. Waiting does.

What we do (and what we do not)

Let us say it clearly, because the boundaries matter: postnatal depression and anxiety are medical and psychological matters, not physiotherapy matters. We do not treat them, we do not diagnose them and we do not take them on in place of those who should.

What we can do is the physical part, which in practice is often what keeps you stuck: getting a body that does not respond as before back into movement after childbirth, managing the lower back or pelvic pain that makes every movement tiring, rebuilding the pelvic floor, and above all making those 80-120 minutes a week feasible so they do not become yet another thing you cannot do. With a newborn at home, "finding time to go to the gym" is often the real reason people never start: for this reason we work by video call, while the baby sleeps, from your home, with exercises that fit into ten minutes.

If you want to start there, the first consultation is free and lasts twenty minutes: you tell us how you are physically, we look together at what is realistic this week, and we tell you honestly whether the missing piece is movement or something else. If it is something else, we say so and point you in the right direction, instead of selling you a programme.

And when you feel ready to raise the bar, the next step, running included, with its real timings, is in returning to running after childbirth: when and how.

Is it normal to feel low in the first days after childbirth?

Yes, and it is far more common than people admit. A systematic review of 26 studies and 5,667 women estimated the prevalence of the baby blues at 39% (95% CI: 32.3-45.6), with individual studies ranging from 13.7% to 76%. These are the days when you cry for no clear reason, feel irritable and fragile: it appears in the first few days and usually resolves on its own within a couple of weeks. What is not normal is that it lasts longer, or gets worse.

How do I tell whether it is baby blues or something more?

The practical test is time and function. The blues is temporary and does not stop you functioning; postnatal depression persists, deepens and takes away your capacity to look after yourself and the baby. A meta-analysis based only on diagnostic interviews (54 studies, 15,586 women) found a prevalence of 12.1% for depression in general and 7.0% for major depression within a year of childbirth, with peaks in the first six months and in particular around weeks 2-3 and 6-8. If after two weeks you feel the same as before or worse, do not wait any longer: talk to your doctor.

Does movement cure postnatal depression?

No, and anyone who tells you it does is doing you a disservice. The most robust systematic review we have on the postpartum period (35 studies, 4,072 women) measured, for exercise-only interventions, a reduction in the severity of depressive symptoms with a standardised mean difference of -0.52 (95% CI: -0.80 to -0.24), which the authors describe as a moderate effect with moderate certainty of evidence. It is a real but partial help: it is an adjunct, not a therapy. Movement goes alongside treatment, it does not replace it and it does not delay its start.

How much movement do you need to feel something?

Less than you might think. In the same review, the estimated threshold for achieving at least a moderate reduction in the severity of depressive symptoms was around 350 MET-minutes a week: the authors translate this as about 80 minutes a week of moderate-intensity activity, for example brisk walking, water aerobics, cycling or strength exercises. Eighty minutes across seven days is just over ten minutes a day. In the meta-analysis dedicated to walking alone, the interventions that seemed to work best were between 90 and 120+ minutes a week.

Which type of activity works best?

Honestly, the comparison between types of exercise is the weakest part of the evidence. Walking is the one with the most concrete data in the postpartum period: five randomised trials of 242 women with mild to moderate depression gave a mean reduction of 4.01 points on the EPDS scale (95% CI: -7.18 to -0.84), although with high heterogeneity. A 2026 network meta-analysis estimated that in the period after childbirth mind-body activities such as yoga and Pilates worked better, but with very wide credibility intervals. The practical answer remains the same: the one you can actually do.

And for anxiety? Is it the same story?

Here you need to be even more cautious, because the data are very limited. In the 2025 review, the effect of exercise on postpartum anxiety symptoms rested on just 2 randomised trials and 513 women, with a standardised mean difference of -0.25 (95% CI: -0.43 to -0.08): the authors themselves describe it as small. And none of the included studies measured whether exercise reduces the chance of developing an anxiety disorder. So: some benefit on symptoms, yes, but it is a far less studied area than mood.

When should I call someone straight away?

Straight away, without waiting for any threshold and without shame, if thoughts of harming yourself or harming the baby cross your mind; if you can no longer look after yourself or the baby; if you do not sleep at all even when the baby sleeps and you feel wired, confused, or hear or see things others do not. This last picture is postpartum psychosis: it is rare, but it is a medical emergency and must be assessed within hours, not days. In that case, call 112 or go to the emergency room.
