Sleep is essential for survival, health, and productivity, and understanding the inequality in time spent sleeping is important. Research suggests that women tend to sleep longer than men by around 11 minutes, and this may be due to biological differences such as hormone production, as well as gender-based differences in responsibilities and social expectations. Women are more likely to experience insomnia, depression, and anxiety, all of which are strongly associated with disrupted sleep. They are also more likely to nap during the day and experience sleep disruptions due to caregiving responsibilities. However, it is unclear whether women need more sleep or if men are simply not getting enough.

What You'll Learn

Women sleep more than men
Women tend to sleep more than men, with research showing that, on average, women sleep for 11 minutes more per night than men. This may be due to a variety of biological and gender-based differences.
Biological Differences
Biological differences, such as hormone production, play a significant role in the amount of sleep a person needs. Women experience hormonal changes throughout their lives, including during menstruation, pregnancy, and menopause, which can impact their sleep cycles and increase their risk of sleep disturbances. For example, during menopause, up to 85% of women experience hot flashes that can disrupt their sleep. Additionally, women are more likely to develop sleep disorders such as restless leg syndrome during pregnancy, and their risk of sleep apnea increases during menopause.
Gender-Based Differences
Gender-based differences in the distribution of paid and unpaid labor, work and social responsibilities, and family caregiving also contribute to women sleeping more than men. Women are more likely to wake up to take care of others, disrupting their sleep. They are also more likely to nap during the day, which can affect their nighttime sleep quality.
Furthermore, women are more likely to experience insomnia, anxiety, and depression, all of which are strongly associated with sleep disturbances. These mental health issues are closely linked to sleep, and the relationship between them is often described as a "chicken-or-the-egg" scenario.
While the reasons behind it are still being explored, the fact remains that women, on average, sleep more than men. Understanding these gender differences in sleep patterns is essential for promoting better sleep health and addressing any underlying issues that may be causing sleep disturbances.

Women's sleep is more disrupted
Hormonal changes also play a significant role in disrupting women's sleep. Women experience hormonal shifts throughout their lifetimes, including during menstruation, pregnancy, and menopause. During menstruation, one-third of people who menstruate struggle to sleep due to physical discomfort and fatigue. Pregnancy can bring about restless leg syndrome and an increased risk of depression, sleep apnea, pain, and incontinence, all of which negatively impact sleep quality.
Menopause is another critical period, with up to 85% of women experiencing hot flashes that disrupt their sleep. Additionally, the risk of developing sleep apnea increases during menopause, causing breathing pauses that interfere with sleep quality. These hormonal changes affect the sleep-wake cycle, which is governed by hormones that regulate feelings of tiredness, alertness, and hunger.
Sociological factors also come into play, with gender-based responsibilities and caregiving duties falling more often on women. Women are more likely to wake up to care for others, disrupting their sleep. They also tend to have more unpaid work and less leisure time, which can contribute to sleep disruptions and reduced sleep quality.
Furthermore, women may be more susceptible to sleep disturbances due to multitasking and using more of their brains, according to researchers at the Loughborough University U.K.-based Sleep Research Center. Poor sleep in women is associated with higher levels of distress, hostility, depression, and irritability.

Women are more likely to have insomnia
There are several reasons why women are more prone to insomnia. Firstly, hormonal changes throughout a woman's life, such as menstruation, pregnancy, and menopause, can disrupt sleep patterns and increase the risk of sleep disturbances. For example, during menopause, up to 85% of women experience hot flashes that can wake them up at night.
Secondly, women are nearly twice as likely to be diagnosed with anxiety and depression, which are strongly associated with insomnia. The overlap between mental health conditions and insomnia creates a cycle where each condition aggravates the other.
Thirdly, gender-based responsibilities, such as caregiving and household chores, often fall disproportionately on women, leading to sleep disruptions and reduced sleep quality. Women are also more likely to be primary caregivers for children and elderly parents, resulting in less sleep time.
Finally, women are more prone to certain health conditions that can contribute to insomnia. For example, polycystic ovary syndrome (PCOS) and fibromyalgia are more prevalent in women and can make sleep more difficult. Urinary incontinence, which affects twice as many women as men due to changes in the reproductive system, can also disrupt sleep by increasing the urge to go to the bathroom multiple times a night.
Overall, the combination of hormonal changes, mental health issues, gender-based responsibilities, and health conditions unique to women contributes to their higher likelihood of experiencing insomnia compared to men.

Women are more likely to have anxiety and depression
Women are twice as likely as men to suffer from anxiety and depression, and this disparity may be caused by a combination of factors, including hormones and environmental factors.
Hormones
Hormones are one of the most significant differences between men and women, and they have a significant impact on mental and emotional health. Women experience far greater hormonal fluctuations throughout their lives, and these changes can affect the brain's wiring. For example, the hormones estrogen and progesterone activate the brain system involved in the fight-or-flight response more readily in women than in men, making them more vulnerable to stress-related disorders.
Societal and Cultural Pressures
Women also face greater societal and cultural pressures, and they are more vulnerable to situations that can trigger anxiety or depression, such as abuse, violence, or economic insecurity.
Brain Chemistry
Differences in brain chemistry may also play a role in the higher prevalence of anxiety and depression among women. The neurotransmitter serotonin, for example, is processed more slowly in the female brain, according to some evidence. Additionally, recent research has found that women are more sensitive to low levels of corticotropin-releasing factor (CRF), a hormone that organizes stress responses, making them twice as vulnerable as men to stress-related disorders.

Women experience hormonal changes
Menstruation
During menstruation, about one-third of people who menstruate experience sleep disturbances due to physical discomforts such as cramps, headaches, and bloating. They also tend to report higher levels of daytime sleepiness, tiredness, and fatigue.
Pregnancy
Pregnancy is associated with hormonal fluctuations that can cause fatigue, drowsiness, and a frequent need to urinate at night. Additionally, pregnant women may develop restless leg syndrome, making it harder to fall asleep. They are also more likely to experience depression, sleep apnea, pain, and incontinence, all of which can disrupt their sleep.
Menopause
During menopause, up to 85% of women experience hot flashes, which can cause night sweats and disrupt their sleep. The hormonal changes during menopause can also increase the risk of developing sleep disorders such as sleep apnea, which can lead to poor sleep quality and excessive sleepiness during the day.
These hormonal changes at different life stages can impact a woman's sleep patterns and overall sleep quality, contributing to their need for more sleep compared to men.
