Why Women Experience Sleep Differently

Sleep Is a Superpower 

Great things happen to the body during sleep. Not only does high quality sleep help you feel more energetic, but it can:

  • Boost your mood
  • Improve heart health and immunity
  • Enhance blood sugar regulation
  • Sharpen memory and cognition
  • Reduce stress
  • Help with weight management
  • And more

Improving sleep quality and duration is one of the most powerful ways to improve health and quality of life. However, getting a good night of rest can be especially elusive for women, who are more than twice as likely to have sleep issues than men.1

In fact, starting in puberty, hormonal shifts cause women to experience sleep differently than men. Given that sleep can have a significant effect on so many aspects of physical and mental health, empowering women to better understand their sleep, identify signs of compromised sleep, and learn how to improve sleep is a key pillar of whole health. 

What Affects Sleep in Women? 

Women face many obstacles when it comes to getting great sleep. This means that when compared to men, women’s sleep is often of a lower quality. Women are more likely to experience sleep deficits due to family and social obligations that compete with sleep.2  And biologically, hormonal changes throughout women’s lives – especially in estrogen, progesterone, melatonin, cortisol, and testosterone – have a significant impact on their ability to get a good night’s rest.3 

Progesterone, a hormone that plays a key part in the menstrual cycle by preparing for the potential for pregnancy, has a big impact on women beyond aiding reproduction: it also impacts sleep quality, breathing, mood, appetite, learning, memory, and sexual activity. Progesterone can induce sleepiness, so when progesterone levels drop right before menstruation and during menopause, women often experience worse sleep and more sleep disturbances. In fact, women with lower progesterone levels (especially post-menopause) are more likely to experience symptoms of obstructive sleep apnea,4 even though it’s most often associated with, and more common, in men.

How Do Hormonal Changes Impact Sleep Throughout Women’s Lives?  

Since progesterone is so closely related to sleep quality, women often experience sleep very differently throughout their lives due to hormonal fluctuations:   
  • Pre-menopause: Women sleep differently depending on where they are in their menstruation cycle. Though much remains to be studied, research suggests that during the follicular and ovulation phases of her cycle, women experience less REM sleep, and during the luteal phase experience more REM sleep.5 The rapid drop in progesterone at the end of the luteal phase might account for why women often report experiencing restless sleep leading up to their period. 
  • Pregnancy: Sleep disturbances are common and tend to worsen as pregnancy progresses,6 when 78% of women reported more disturbed sleep during pregnancy than at any other time in their lives. Most obviously, physically carrying a child can result in some discomfort and therefore a worse night’s sleep.7 However, hormone changes can also result in more fragmented sleep, more light sleep, and less deep sleep.8 
  • Peri-Menopause: During menopause estrogen and progesterone levels drop significantly, which have major impacts on sleep. Since estrogen helps regulate body temperature at night, no longer producing it can mean women feel too warm, leading to worse sleep. And drops in progesterone can trigger relaxation in upper airways, resulting in lapses in breathing, a sign of sleep apnea. The hormonal changes associated with menopause that trigger hot flashes, night sweats, insomnia, mood changes, and fatigue all make sleep challenging during this time.9 
  • Post-Menopause: After menopause, the body ceases to naturally produce estrogen and progesterone, and issues sleeping are very common among post-menopausal women. The incidence of obstructive sleep apnea and insomnia are significantly higher in this group10 and developing a better understanding of sleep issues related to menopause is now the subject of more scientific research.

So, What Can You Do to Get Better Sleep? 

Many women experience poor sleep, but you don’t have to accept it as a fact of life. There are steps you can easily take to understand your unique sleep patterns and get more restful sleep.

Tracking sleep duration, sleep quality, resting heart rate, and heart rate variability can help you piece together a picture of what’s happening while you sleep, and help you identify daytime behaviors – biometric triggers – that contribute to better sleep quality.    

  • Tracking sleep duration can help easily identify if you’re getting less than the recommended 7 to 9 hours of sleep per night for optimal health and indicate when to adjust your bedtime routine to get enough time in bed. 
  • Women’s resting heart rate increases throughout the menstrual cycle right in the days leading up to her period.11 Tracking when it’s fluctuating higher than your nightly average can help you identify why you’re not getting a restful night’s sleep and suggest when it’s time to incorporate a calming behavior before bedtime, such as meditation or deep breathing. 
  • Heart rate variability typically increases at the start of your menstrual cycle when progesterone and estrogen levels are low. However, this higher HRV makes REM sleep more challenging. Understanding your own patterns when HRV is elevated while sleeping can help identify when to focus on improving sleep hygiene and introducing relaxation strategies into your day.12 

The Takeaway

Sleep is incredibly important. Not only is it time for the body to restore, women who are not getting a good night of sleep are also more likely to experience declines in mental health and productivity as well.13 

Women very often experience sub-optimal sleep, both in quality and duration. And fluctuating hormones, especially progesterone, are often to blame. There are steps you can take to get the sleep you need. Understanding when and why in your menstrual cycle you’re experiencing suboptimal sleep throughout your biological cycle can help you make changes during the day as well as optimize your time in bed.
