There is some debate about whether women need more sleep than men. While some sources claim that women need more sleep, others argue that the difference is minimal and influenced by external factors. Research has shown that women tend to sleep longer than men, but only by about 11 to 20 minutes on average. This difference is thought to be due to a combination of biological and gender-based factors.
Biologically, women are more prone to sleep disorders such as insomnia, anxiety, and depression, which are all linked to disrupted sleep. Hormonal changes during menstruation, pregnancy, and menopause can also impact women's sleep. For example, one-third of menstruating individuals experience sleep disturbances due to cramps, headaches, and bloating. Additionally, pregnancy can increase the likelihood of depression and restless leg syndrome, while menopause can cause hot flashes and increase the risk of sleep apnea, all of which can disrupt sleep.
Gender-based differences in responsibilities and societal expectations also play a role. Women are often the primary caregivers, both for children and aging parents, which can result in sleep interruptions. They also tend to spend more time on unpaid labor, such as housework, which can impact their sleep duration and quality.
While the reasons behind the disparity are still being explored, it is clear that adequate sleep is crucial for overall health and well-being, and addressing sleep issues is essential to prevent further health complications.

What You'll Learn

Sleep disorders
Women, in particular, are at an increased risk of developing sleep disorders. Research shows that they are 40% more likely to experience insomnia compared to men. They also have a higher risk of developing restless leg syndrome and sleep apnea, which can impact their overall sleep quality. Hormonal fluctuations during menstruation, pregnancy, and menopause can further disrupt their sleep patterns. For instance, during menopause, up to 85% of women experience hot flashes and night sweats that can interrupt their sleep.
Additionally, gender-based differences in daily responsibilities and social expectations contribute to sleep disparities between men and women. Women are more likely to engage in unpaid labor, such as family caregiving and housework, which can lead to sleep interruptions. They also tend to nap more during the day, which may compensate for fragmented nighttime sleep. These factors collectively suggest that women might require slightly more sleep than men to function optimally.

Hormone changes
Menstruation
Hormonal changes during the menstrual cycle can affect sleep patterns. As estrogen and progesterone levels rise and peak before ovulation, women may feel sleepier and find it easier to fall asleep. However, right before a period, when hormone levels drop, women may feel more alert. Hormonal changes can also cause physical symptoms such as cramping, headaches, and bloating, which can interrupt sleep. One-third of people who menstruate report having trouble sleeping due to these symptoms and experiencing higher levels of daytime sleepiness, tiredness, and fatigue.
Pregnancy
Pregnancy can also impact a woman's sleep. Hormonal fluctuations during pregnancy can lead to the development of restless leg syndrome, making it harder to fall asleep. Pregnant people are also more likely to experience depression, sleep apnea, pain, and incontinence, all of which can disrupt sleep. These sleep issues can continue into the postpartum period when hormone levels drop and the demands of caring for a newborn with an irregular sleep cycle can result in even more daytime sleepiness.
Menopause
During menopause, up to 85% of women experience hot flashes, which can disrupt sleep when they occur at night. Additionally, the risk of developing sleep apnea increases during menopause. This sleep disorder causes pauses in breathing, leading to lower sleep quality and increased tiredness during the day.
While the exact amount of additional sleep needed by women due to these hormonal changes is unclear, research suggests that it could be between 11 and 20 minutes per night.

Menstruation, pregnancy, and menopause
Sleep is affected by hormonal changes, stress, depression, aging, and life transitions. The menstrual cycle is associated with changes in circadian rhythms and sleep architecture. Women with severe premenstrual syndrome often report more disturbing dreams, sleepiness, fatigue, decreased alertness, and concentration during the premenstrual phase.
Menstruation and Sleep
Hormonal changes during menstruation can cause sleep disturbances. Women with severe premenstrual syndrome (PMS) often report more disturbing dreams, sleepiness, fatigue, decreased alertness, and concentration during the premenstrual phase. Sleep disturbances are also commonly reported during pregnancy and increase in frequency and duration as the pregnancy progresses.
Pregnancy and Sleep
Pregnancy brings about significant fluctuations in hormones that affect the sleep-wake cycle and cause physiologic changes that lead to sleep disturbances. Common physical symptoms, such as anxiety, urinary frequency, backache, fetal movement, general abdominal discomfort, breast tenderness, leg cramps, heartburn, and reflux cause sleep disturbances during pregnancy.
Pregnant women don't sleep as deeply and may wake up more often during the night. This means they need to spend more time in bed. It is recommended that pregnant women follow good sleep hygiene practices, such as maintaining a regular sleep schedule, avoiding naps in the late afternoon or evening, and developing a bedtime routine.
Menopause and Sleep
The menopausal transition is a time when women may experience sleep problems due to various factors, including hot flashes, night sweats, changes in mood, and depression. Hormonal fluctuations and vasomotor symptoms such as night sweats may be the initial cause of insomnia during menopause, but physiological arousals, behavioral conditioning, and misguided coping attempts appear to prolong insomnia.
Treatment Options
Treatment options for sleep disturbances during menstruation, pregnancy, and menopause include pharmacological interventions such as sedative-hypnotics, benzodiazepines, and antidepressants, as well as non-pharmacological treatments such as cognitive-behavioral therapy for insomnia (CBT-I), yoga, acupuncture, mindfulness, reflexology, and exercise.

Gender-based responsibilities
Several factors contribute to gender-based differences in sleep duration and quality, including gender-based responsibilities, biological differences, and societal expectations.
Firstly, women often shoulder a disproportionate burden of unpaid labour, including family caregiving and housework. This dynamic was highlighted in a 2013 study, which found that women spent less time in the workforce and more time on unpaid labour. As a result, women may have more opportunities for sleep during the day but are also more likely to experience sleep interruptions due to caregiving responsibilities. This dynamic can contribute to overall sleep quality, as fragmented sleep can lead to daytime sleepiness.
Secondly, gender norms and expectations can influence sleep patterns. For example, women may feel pressured to prioritise self-care and health maintenance, leading to earlier bedtimes or naps. Additionally, women are more likely to experience anxiety and depression, which are strongly associated with insomnia and sleep disturbances. These mental health disparities may be influenced by societal expectations and gender roles that contribute to increased stress and pressure on women.
Furthermore, gender-based differences in paid labour and leisure activities can impact sleep. Men tend to spend more time working outside the home and engaging in leisure activities, which may result in them having fewer hours for sleep. This dynamic was observed in a study that analysed Census Bureau data, finding that men slept approximately 11 minutes less than women on average. However, the study authors suggested that this gap could be attributed to "gendered time tradeoffs," with men prioritising work and leisure over sleep.
In conclusion, gender-based responsibilities, societal expectations, and biological differences all intersect to influence sleep patterns and duration for women and men. These factors contribute to the complex dynamics of sleep and highlight the need for further research in this area.

Anxiety and depression
Women are nearly twice as likely to be diagnosed with anxiety and depression, and these conditions are strongly associated with insomnia. The relationship between mental health and sleep is a "chicken-or-the-egg" scenario, where poor sleep can affect your mental health, but depression also makes you more likely to have trouble sleeping.
Women are 40% more likely to experience insomnia than men, and insomnia is linked to both anxiety and depression. Of people with depression, 80% experience insomnia, 20% have obstructive sleep apnea, and 15% have hypersomnia (oversleeping).
Hormonal changes can also play a role in anxiety and depression, and these hormonal changes can impact sleep. For example, during menopause, women may experience hot flashes that disrupt their sleep. Pregnancy can also increase the likelihood of depression, sleep apnea, and restless legs syndrome, which can make it harder to fall asleep.
Additionally, gender-based responsibilities, such as caregiving, can affect sleep duration in women. Women are more likely to wake up during the night to take care of others, which can disrupt their sleep.
To improve sleep, it is recommended to create a sleep-friendly routine, avoid caffeine and alcohol, exercise regularly, and manage mental health through meditation, journaling, or therapy.
