Many women experience sleep disturbances at various points in their menstrual cycle. Here’s how your period may affect your sleep and what to do about it.

Many of us experience poor-quality sleep from time to time. And though statistics vary, studies consistently show that women are more affected than men. One review paper from 2006 found that women are at 40% greater risk of insomnia.

Hormones and sleep

There are a few possible reasons for this gender discrepancy, but a key culprit is hormonal fluctuations. 

Insomnia is more common in women during pregnancy, perimenopause, and at certain points of the menstrual cycle. According to the National Sleep Foundation in the USA, 30% of women report disturbed sleep during their period, along with 23% the week beforehand.

“All women are different – some might find that their sleep quality is affected by their menstrual cycle, whereas others will not,” says Sara Matthews, consultant gynecologist at the Portland Hospital.

“Our circadian rhythm regulates our sleep pattern, which is influenced by estrogen and progesterone fluctuations throughout the menstrual cycle.”

She adds that while sleep is usually uninterrupted in the first half of the cycle, issues can begin after ovulation.

“At this point, cortisol levels can increase, melatonin levels decrease, body temperature is slightly higher, and REM sleep diminishes,” she says. “Later in the luteal phase (the second half of your cycle, in a couple of weeks before your next period), the drop in estrogen and progesterone that heralds the coming of a period is classically associated with disturbed sleep. 

Some women, especially those in the teenage and perimenopausal years, also experience night sweats.”

How sleep disturbances relate to PMS

If you’ve ever spent the night before your period tossing and turning in bed – perhaps throwing off your duvet because you’re suddenly too hot – you’ll be all too familiar with this situation. 

As Dr. Nerina Ramlakhan, a physiologist and sleep expert, explains, this part of the cycle is often associated with changes in mood, body temperature, and energy levels, along with physical symptoms.

“These can include bloating and other stomach disturbances, pain and cramps, light and noise sensitivity, constipation or diarrhea, and appetite changes,” she says. “All of this can have a disruptive effect on sleep for some women. 

Some might have difficulty getting to sleep or staying asleep, oversleeping, or not getting enough sleep. Others might have more vivid and disturbing dreams. With severe PMS, there might be a combination of these sleep problems.”

One 2012 study found that women with severe PMS were around twice as likely to experience insomnia. Among women with premenstrual dysphoric disorder (PMDD), a very severe form of PMS, 66% experience sleep problems, 72% feel depressed, and 84% feel tired. 

It can sometimes be hard to work out what comes first – are you sleeping badly because of anxiety and low mood, or is the low mood a product of sleeping badly?

Either way, it comes down to your hormones. One study found that women whose progesterone levels rise more sharply during their cycle are more likely to experience sleep disturbances towards the end.

“In some cases, sleeping for shorter periods can be associated with having an irregular menstrual cycle,” adds Intimina’s consultant gynecologist Dr. Shree Datta.

As Matthews explains, while it’s unusual for younger women to have significant sleep disturbance related to their cycle, it’s worth keeping a sleep diary to work out your patterns. 

Other reasons for a poor night’s sleep include stress, a chaotic work schedule, poor sleep ‘hygiene,’ and certain medications and medical conditions, along with caffeine, nicotine, and alcohol.

How to sleep better during your period

So what can you do to get a better night’s shut-eye if you’re struggling with period-related sleep problems? 

To a large extent, the answers are the same as they would be for anyone dealing with sleep problems (though with an added focus on mitigating physical symptoms).

Work on your bedtime routine

“Have a warm bath or shower before bedtime, don’t use a phone or watch TV in bed. Try reading a book, or even better, have sex with your partner if that is an option!” says Matthews. “Change your sheets the week before a period is due, and maybe try some ambient noise in the bedroom, like a fan, to drown out any other sound. 

Some hot milk or chamomile tea to drink on the way to bed, or a herbal valerian supplement or low-dose melatonin tablet, will helps to fall asleep. Try to avoid taking prescription sleeping pills.”

Managing your hormones

She adds that since many PMS symptoms worsen when carbohydrate cravings kick in, it’s worth cutting back on sugar in the second half of your cycle. 

If none of these techniques help, you could always see the doctor about taking the pill – but this needn’t be your first port of call.

“It’s unlikely the reproductive hormones will need to be altered to deal with sleep problems,” says Natasha Richardson, an expert in menstrual health and author of Your Period Handbook

“It’s more likely that there are lifestyle and dietary changes to be made, which will support overall well-being. By doing this, there won’t be any underlying problem for the normal hormone changes to exacerbate.”


Dr. Ramlakhan suggests five ‘non-negotiables’ for getting a good night’s sleep, whether or not your period is fuelling insomnia. 

These are:

  • Don’t skip breakfast.
  • Cut back on caffeine.
  • Stay well hydrated.
  • Go to bed early.
  • Set healthy technology boundaries.

“You could seek relief in complementary therapies while cultivating self-awareness, perhaps with a regular meditation or mindfulness practice,” she says. “Allow the thirty-odd years of having periods to hone your self-care and lifestyle habits as practice for when the menopause arrives.”

Seeking help

Finally, it’s important to seek help if your sleep problems interfere with your ability to function during the day.

“Sleep is a sign of our overall well-being. We need to be healthy to have good sleep and good sleep to be healthy. 

Period Cramps

If you get periods, you will likely have experienced period cramps and pain at some point. Thankfully, menstrual cramps can usually be managed using tried and tested methods at home.

If you’ve been having periods for a while, you might be able to notice the tell-tale signs of period cramps in your tummy, back, and legs, whether it’s dull and constant or short painful spasms. But what causes it?

What causes period cramps?


“Painful periods, or menstrual cramps, are caused by contractions in the womb as it expels the womb lining and presses on blood vessels, which temporarily cut off the blood supply and restrict oxygen,” says Dr. Vanessa Mackay, consultant gynecologist and spokesperson for the 

Royal College of Obstetricians and Gynaecologists. This causes the tissues in the womb to release chemicals triggering pain.

These contractions can cause cramps and discomfort during your period and make concentrating difficult during everyday tasks. 

In fact, a recent study found that period cramps account for nine days of lost productivity for women each year.

Period pain follows a pattern that distinguishes it from ordinary stomach or back pain. “Period cramps are usually at their most intense during the first few days of bleeding and can vary for each woman,” says Mackay.

According to Mackay, period cramps should only occur a few days before or during your period. “It is a good idea to seek advice if this menstrual pain continues throughout the month as this may be a symptom of a different problem.”

How to help period cramps

If your period pain isn’t caused by an underlying condition or causing severe pain, you should be able to treat it without seeing a doctor.

How does heat help period cramps?

“Many women find that heat is helpful to manage their period cramps, so using a hot water bottle or a heating pad or having a warm bath could provide some comfort,” says Mackay. Heat is a cheap, effective, and side-effect-free way to relieve pain. One study found that using a heating pad was as effective as painkillers.

Warmth applied directly to the pelvic area may help relax the uterus muscles, whilst a warm bath or shower can help relax your whole body.


The severity of your period cramps isn’t just down to chance. Lifestyle factors like weight and smoking also play a role. “It is important for those who smoke to try to stop, as this is thought to increase the likelihood of experiencing period pain,” says Mackay. 

Quitting smoking is one of the best things you can do for your health, and there’s plenty of support available.
