Why your period is keeping you up at night (& what you can do about it)

Wide awake at 2am, on your period and scrolling page 1 of Google? Welcome, you’re in very good company.

Insomnia during period week is one of those symptoms no one really warns you about. I personally struggle so much with sleep during this time – one month it’s horrible insomnia before period, the next it’s insomnia first day of period and sometimes it’s just… not really sleeping properly at all until my cycle moves on.

This kind of period insomnia can be seriously frustrating, especially if you normally sleep well, or if you have a lot of pain in the mix. 

The good news? There are real reasons this happens, and there are a few things I’ve tried in my time that help me make it easier.

Here’s the quick lowdown.

Can periods cause insomnia​?

Yes. Periods can absolutely cause insomnia and it’s not “all in your head.”

Your menstrual cycle affects hormones that play a direct role in sleep. 

Estrogen and progesterone rise and fall throughout the month, and progesterone in particular supports calm, sleepy feelings in the body. When progesterone drops right before or during your period, sleep often gets lighter, more restless, or harder to come by. Want to learn more? Dive into our write-up on hormonal insomnia here.

On top of that, your period can obviously bring physical discomfort like cramps, bloating, headaches, and back pain too. And for many of us, even mild discomfort is associated with poor sleep quality, and can stop us from fully relaxing. Boo.

Horrible insomnia before your period​? This might be why

That awful stretch of sleepless nights right before your period starts is pretty common. A friend of mine is known for posting in our group chat at 3am during this time, so it’s something we’ve grown to joke about.

This phase of your cycle comes with a sharp hormonal shift. Progesterone drops, and estrogen fluctuates, which can look like:

• lying in bed feeling tired but wired
• racing thoughts or anxiety at night
• waking up multiple times
• very light sleep that doesn’t feel restful

Horrible insomnia before period week often shows up alongside other PMS symptoms like irritability, low mood, or increased stress sensitivity. Your brain is just less inclined to switch off, and that timing makes total sense.

Insomnia on your first day of period​

On the other hand, for some of us, sleep issues might peak once bleeding begins.

Insomnia on the first day of period often connects to physical symptoms, as well as the hormonal changes. Cramps, pelvic pressure, digestive changes, and temperature shifts can all interfere with sleep, even if pain isn’t severe.

Have heavy periods? Blood loss during your period also linked to low iron and iron-deficiency anemia, conditions which can impact your energy levels and might leave you feeling exhausted but unable to sleep deeply. That combination is especially frustrating.

But what’s really normal, here?

Is it normal to have insomnia during your period​? 

Yes, it’s very normal to have insomnia during your period, even if it only happens every now and then.

Some people notice sleep issues before their period, others during it, and some experience both. The pattern can change month to month depending on stress, routine, diet and overall health, and isn’t usually a cause for concern.

That said, if insomnia during period weeks is severe or affecting your daily life in a big way, talk to your healthcare provider for extra support.

How to help insomnia during your period​ – our team’s tried & tested tips

I’ve tested a lot of late-night strategies over the years, and, asking from behind my laptop at TRB HQ, so have the rest of the team. These are the ones to try:

1. Lean into comfort – Okay this one is obvious, but think extra pillows, a hot water bottle on your lower abdomen, soft pajamas or a super-soft pad – bookmark our non-toxic tampons for more on our fav period care products right now.
2. Keep nights predictable – Going to bed and waking up at the same time helps your body know what to expect, even when hormones are doing their thing.
3. Watch caffeine timing – Caffeine can hang around longer during certain parts of your cycle. Cutting it off earlier in the day can reduce insomnia on period nights.
4. Gentle movement earlier in the evening – Stretching, slow yoga, or a short walk can ease cramps and tension without overstimulating your system.
5. Try natural support – Science-backed supplements might feel supportive. Looking for recommendations? Check out these PMS supplements from Dr. Vegan, plus our team’s rave review. 
6. Catch pain early – If cramps keep you awake, addressing them before bed (with heat, gentle movement or pain relief) can make a big difference. I swear by the Myoovi Period Pain Relief Device for an hour or so before I start to wind down.
7. Track and advocate – Noticing when insomnia or other symptoms hit each cycle can help you prepare ahead of time with earlier nights and extra rest, as well as arming you with ammo to visit your provider, especially if period pain keeps you up at night.
