Have you ever gone to bed at the same time as your husband or partner, gotten the same number of hours of sleep, and wondered why <\/span><\/span>you<\/span><\/span><\/strong> are still exhausted the next morning?<\/span><\/span><\/span><\/p>\n<\/div>\n\n
There may actually be biological reasons for that.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
You’ll often see headlines claiming that women need exactly 20 minutes, 30 minutes or even an hour more sleep than men. The research isn’t quite that specific. There is <\/span><\/span>no established scientific recommendation that every woman needs a set number of extra minutes of sleep simply because she’s a woman<\/span><\/span><\/strong>. Current sleep guidelines recommend that healthy adults regularly get at least seven hours of sleep, without separate targets for women and men. <\/span><\/span><\/span><\/p>\n<\/div>\n\n
But that doesn’t mean women and men experience sleep in exactly the same way.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
Research increasingly shows important sex differences in sleep, and women are particularly vulnerable to sleep disruption during periods of hormonal change\u2014including the menstrual cycle, pregnancy, postpartum, perimenopause and menopause. Women also report more insomnia and non-restorative sleep than men. <\/span><\/span><\/span><\/p>\n<\/div>\n\n
So rather than saying every woman needs exactly 30 extra minutes of sleep, I think the more useful conversation is this:<\/span><\/span><\/span><\/p>\n<\/div>\n\n
Women’s bodies often place different demands on sleep, and many women may need more sleep\u2014or more opportunity for restorative sleep\u2014than they’re currently getting.<\/span><\/span><\/strong><\/span><\/p>\n<\/div>\nWomen’s Hormones and Sleep Are Closely Connected<\/span><\/span><\/span><\/h2>\n<\/p>\n\n
One of the biggest differences between women’s and men’s sleep is something women deal with throughout much of their lives: fluctuating reproductive hormones.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
Estrogen and progesterone don’t only affect reproduction. Hormonal changes are associated with differences in sleep quality, sleep architecture and the likelihood of sleep disturbances. <\/span><\/span><\/span><\/p>\n<\/div>\n\n
That means your sleep can change throughout your menstrual cycle.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
It can change during pregnancy.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
It can change dramatically after having a baby.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
And then perimenopause arrives and changes the rules again.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
This is one reason I don’t look at poor sleep in a woman as simply a question of whether she’s spending eight hours in bed.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
We have to ask <\/span><\/span>what is happening hormonally and physiologically during those eight hours.<\/span><\/span><\/strong><\/span><\/p>\n<\/div>\nYour Menstrual Cycle Can Affect How Well You Sleep<\/span><\/span><\/span><\/h2>\n<\/p>\n\n
Some women notice that they sleep beautifully during one part of their cycle and terribly during another.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
There is physiology behind that.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
Research shows that reproductive hormones influence sleep throughout the menstrual cycle, with sleep disturbances particularly evident during certain phases. Changes in progesterone, body temperature and other physiological processes may all contribute. <\/span><\/span><\/span><\/p>\n<\/div>\n\n
Think about the woman who sleeps reasonably well most of the month but suddenly experiences restless sleep, vivid dreams, night waking or daytime fatigue right before her period.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
She may technically be getting the same number of hours in bed.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
But those hours don’t necessarily <\/span><\/span>feel equally restorative<\/span><\/span><\/strong>.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
And if poor-quality sleep repeats month after month, that sleep debt can start to add up.<\/span><\/span><\/span><\/p>\n<\/div>\nThen Perimenopause Changes Sleep Again<\/span><\/span><\/span><\/h2>\n<\/p>\n\n
This is where I see sleep become a major issue for many women in my practice.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
A woman who slept perfectly well throughout her 20s and 30s suddenly reaches her 40s and starts waking at <\/span><\/span>2:00 or 3:00 in the morning<\/span><\/span><\/strong>.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
Sometimes her heart feels like it’s racing.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
And sometimes she’s simply wide awake staring at the ceiling thinking about something completely ridiculous from 2007.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
Hormonal fluctuations during perimenopause are associated with an increased likelihood of sleep disturbances, and sleep problems become especially common during the menopausal transition. Hot flashes and night sweats can further fragment sleep. <\/span><\/span><\/span><\/p>\n<\/div>\n\n
A 2026 review reports that approximately <\/span><\/span>40\u201360% of women experience sleep disturbances during menopause<\/span><\/span><\/strong>, including insomnia and fragmented sleep. <\/span><\/span><\/span><\/p>\n<\/div>\n\n
This is why telling a perimenopausal woman to simply \u201cget eight hours of sleep\u201d can miss the point.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
She may be <\/span><\/span>trying<\/span><\/span><\/em> to get eight hours.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
Her body just isn’t cooperating.<\/span><\/span><\/span><\/p>\n<\/div>\nWomen Are More Prone to Insomnia<\/span><\/span><\/span><\/h2>\n<\/p>\n\n
Women are more likely than men to experience insomnia, particularly after reproductive hormones begin fluctuating. Research reviews have consistently found greater subjective sleep complaints among women even though some objective measurements suggest women may actually sleep slightly longer or have better sleep efficiency than men. <\/span><\/span><\/span><\/p>\n<\/div>\n\n
That sounds contradictory, but it tells us something important.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
Sleep duration and restorative sleep aren’t necessarily the same thing.<\/span><\/span><\/strong><\/span><\/p>\n<\/div>\n\n
You can spend eight hours in bed and still wake up exhausted if your sleep is repeatedly interrupted or you aren’t getting the restorative sleep your body needs.<\/span><\/span><\/span><\/p>\n<\/div>\n\n
That’s why I pay attention to questions such as:<\/span><\/span><\/span><\/p>\n<\/div>\n\n
Do you wake throughout the night?<\/span><\/span><\/span><\/p>\n<\/div>\n
