When we first started trying to conceive (and later when we moved into IVF) we were told to keep living our lives and not to put everything on hold – something we’re sure many people hear.
And sure, that advice made sense. The only problem was that our “normal” wasn’t exactly relaxed. It was early mornings, long workdays, a full social calendar, life admin, endless fertility research, and trying to fit treatment around everything else. We kept going because that’s what we thought we were supposed to do.
Looking back, one thing nobody talked to us about was sleep. No one suggested slowing down. No one talked about rest as part of the process. Yet, the more we learned, the more we realised that sleep isn’t just downtime. It’s one of the ways our bodies recover, regulate hormones, manage stress, and build resilience through what can be a physically and emotionally demanding journey.
It turns out sleep may play a bigger role than many of us realise, especially during IVF.
The Nights IVF Doesn’t Prepare You For
No one tells you how much IVF can change your nights.
We had heard about the injections and the scans, but what we didn’t expect was for sleep to become harder just when we seemed to need it most.
Some nights it was the racing thoughts. Other nights it was waking up at 3am and not being able to get back to sleep. Sometimes it was the hormones, the anxiety, or simply the weight of carrying so much uncertainty. Sometimes it wasn’t even a specific worry. It was simply the feeling that our minds never fully switched off.
As each of our IVF journeys progressed, we both found ourselves craving earlier nights, sneaking in naps, and feeling more tired than we ever expected. Looking back, it felt like our bodies were asking for more rest long before we realised we needed it.
What we’ve since learned is that sleep isn’t just about feeling refreshed the next day. It’s quietly involved in hormone regulation, recovery, stress resilience, and many of the biological processes happening behind the scenes during fertility treatment.
Of course, good sleep doesn’t guarantee IVF success, and poor sleep isn’t something to blame yourself for. This isn’t about creating another thing to worry about or get perfect.
It’s simply about recognising that rest matters. Your body is doing a huge amount of work during IVF, and sometimes the kindest thing you can do is give it permission to slow down.
That’s what we’d like to explore in this post.
Why Sleep Rarely Comes Up in IVF Conversations
One thing we’ve wondered is why nobody talks about sleep more during IVF.
So much of fertility treatment focuses on the things clinics can measure: hormone levels, follicle counts, scans, blood tests, and lab results. Sleep happens at home. It’s harder to measure, easier to overlook, and often left out of the conversation entirely.
Yet during IVF, your body is doing a huge amount behind the scenes. Hormones are changing, follicles are growing, procedures require recovery, and there’s often a steady undercurrent of stress and uncertainty running through it all.
Looking back, it’s no surprise so many of us struggle with sleep during treatment.
Turns out that research backs that up too. One large study found that around 30% of people starting IVF met the criteria for poor sleep quality, significantly higher than in the general population.
That certainly matched our experience. So if sleep has felt harder, lighter, or more unpredictable during treatment, you’re not imagining it – and you’re definitely not the only one.
What The Research Says
When we started looking into the research around sleep and IVF, it wasn’t one dramatic finding that stood out.
It was the pattern.
Study after study seemed to point in the same direction: sleep may be playing a bigger role in fertility treatment than many of us realise.
In one study of more than 1,200 women undergoing IVF and ICSI, those sleeping fewer than seven hours a night tended to retrieve fewer eggs and fewer mature eggs than those sleeping seven to eight hours. People who regularly struggled to fall asleep also tended to have fewer mature eggs, fertilised eggs, and good-quality embryos.
That doesn’t mean poor sleep causes IVF cycles to fail. But it does suggest that sleep may help support how the ovaries respond during treatment, particularly when the body is already under significant hormonal demand.
Another smaller study using wearable sleep trackers found something similar. Women who slept longer before treatment tended to retrieve more eggs, even after accounting for factors like ovarian reserve.
Taken together, the research suggests that sleep isn’t just happening in the background. It’s one of the many things quietly supporting your body while it does the incredibly hard work of IVF.
It’s Not About Sleeping “Enough”
One of the most reassuring things we found in the research is that sleep doesn’t have to be perfect to be supportive.
Because let’s be honest, IVF and perfect sleep rarely go together.
You can be exhausted and still struggle to fall asleep. You can spend eight hours in bed and wake up feeling like none of it counted. We had nights like that.
What’s interesting is that the research doesn’t suggest that more sleep is always better. In fact, very long sleep durations have been linked to poorer outcomes in some groups.
Instead, sleep quality seems to matter more than chasing a perfect number of hours.
Several studies have found that people reporting better-quality sleep tended to have higher pregnancy and live birth rates than those reporting poorer sleep, even when they weren’t necessarily sleeping longer.
Of course, these studies show patterns, not predictions, and they don’t tell us what will happen in any individual IVF cycle.
But what they do is offer an important reminder that this isn’t about achieving perfect sleep. It’s about supporting rest where you can, being gentle with yourself when sleep is difficult, and recognising that even small improvements may matter more than you think.
When You Sleep Matters Too
When we think about sleep, we usually focus on how much we’re getting. But it turns out when we sleep may matter too.
Research suggests that very irregular sleep patterns and consistently late nights may be linked to certain IVF outcomes. While the reasons aren’t fully understood, our bodies run on internal clocks that help regulate hormones and reproductive function.
That doesn’t mean you need a perfect bedtime or strict routine. IVF is challenging enough without turning sleep into another thing to optimise.
What the research does suggest is that disrupted sleep can sometimes be a sign that the body is under more strain.
For us, that felt relatable. The treatment itself, the uncertainty, and the mental load can all make it harder to maintain the routines that usually help us feel balanced.
That doesn’t mean disrupted sleep stops IVF from working. It’s simply another reminder that your body is carrying a lot during this time.
IVF Doesn’t Exactly Help Sleep Either
Here’s the part that rarely gets talked about: IVF itself can make sleep harder.
It’s the hormone changes, waking up early for appointments, the anxiety and waiting
The uncertainty. Trying to hold hope and fear at the same time.
Feel familiar?
Studies consistently show higher rates of poor sleep, insomnia, and anxiety during IVF treatment, and looking back, that makes perfect sense to us.
IVF places demands on both the body and mind. Stress can make sleep more difficult, and poor sleep can make everything feel harder to carry.
It’s not a personal failing. It’s not because you’re not trying hard enough to relax. Sleep becomes harder because your system is already working overtime.
Some things can help lighten the load, even if they don’t magically fix sleep itself. Research suggests that approaches like acupuncture and mindfulness-based support may help reduce stress and anxiety for some people during IVF. Melatonin comes up a lot in fertility conversations too. While it may have benefits for egg and embryo quality through its antioxidant properties, studies haven’t consistently shown that it improves sleep during IVF.
Perhaps the most important thing to know is this:
If your sleep feels fragile during treatment, you’re not doing anything wrong.
It’s often a reflection of how much your body and mind are carrying right now.
What This Research Doesn’t Say
It’s just as important to talk about what the research doesn’t tell us. It doesn’t tell us that sleep guarantees pregnancy. It doesn’t tell us that a few bad nights can ruin a cycle.And it doesn’t mean that if you’re struggling to sleep during IVF, you’re somehow doing treatment “wrong.”
Like most fertility research, these studies show patterns rather than causes. Much of the sleep data is self-reported, and individual biology plays a huge role in how people respond to treatment.
The biggest takeaway for us wasn’t that sleep needed to be optimised. It was that sleep deserves a little more attention and compassion than it often gets.
This isn’t about adding another thing to your IVF to-do list. It’s about recognising that rest matters, and being gentle with yourself when sleep feels difficult.
Final Thoughts - Reframing Sleep During IVF
Nope, you don’t need perfect sleep for IVF.
Sleep isn’t another thing to optimise or get right. It’s part of the support system helping your body recover through something physically and emotionally demanding.
One of the biggest shifts for us was realising that rest wasn’t something we had to earn. Earlier nights, slower mornings, and the occasional guilt-free nap weren’t signs of laziness – they were signs that our bodies were working hard.
We tried to practice a little more self- kindness and swapped “Am I sleeping well enough?” to “Is my body getting the rest and support it needs right now?”
We gradually came to see sleep differently, not as something to achieve. But as one of the ways we could support ourselves during IVF.
So if sleep feels fragile at times, you’re not failing. You’re responding to something that asks a great deal of both your body and your mind.
