Sleep: Why Women Need More Shut-Eye Than Men

do woman need more sleep than men cdc

Women need more sleep than men, and there are several reasons for this. Firstly, women are more likely to experience sleep disorders such as insomnia, depression, and anxiety, which are strongly associated with disrupted sleep. Secondly, hormonal changes during menstruation, pregnancy, and menopause can impact a woman's sleep cycle and increase the need for sleep. Thirdly, gender-based responsibilities such as caregiving and unpaid labour can result in sleep disruption for women. While the recommended sleep duration for adults is seven to nine hours, women tend to sleep on average 11 minutes longer than men. However, this small difference in sleep duration represents genuine variations between the sexes and their sleep patterns.

Fluctuating hormones

Menstruation

During the week before a woman's period, progesterone levels rise to prepare the body for a potential pregnancy. If there is no pregnancy, progesterone levels decrease, causing the uterine lining to shed and starting the menstrual cycle. Immediately before bleeding begins, a woman's progesterone levels dip dramatically, which is why some women struggle to get quality sleep in the days leading up to their period.

Pregnancy

During pregnancy, progesterone and estrogen levels increase significantly to support the growing fetus. This surge in hormones may be why many women feel drowsy and take more naps during the first trimester. However, by the third trimester, other factors such as frequent urination, restless leg syndrome, and difficulty breathing can disrupt sleep.

Menopause

As a woman approaches menopause, her hormone levels fluctuate dramatically, causing night sweats and hot flashes that can interrupt sleep. Additionally, lower progesterone levels can make women more irritable and less able to relax. Research suggests that the decrease in progesterone and estrogen during menopause may also contribute to a higher risk of developing sleep apnea, a disorder that causes breathing interruptions during sleep.

Polycystic Ovary Syndrome (PCOS)

Women with PCOS may experience irregular periods, higher testosterone levels, and lower progesterone levels, which can exacerbate sleep difficulties. Studies show that women with PCOS are also at a higher risk of developing sleep apnea.

Hormones Affecting Sleep

Several hormones play a role in regulating sleep and wakefulness. Melatonin helps to wind down the body before bed, while cortisol promotes alertness and wakefulness in the morning. Ghrelin, insulin, growth hormone, and testosterone also rise and fall during different stages of the sleep cycle. When these hormones are out of balance, it can lead to insomnia and other sleep disturbances.

Higher rates of depression and anxiety

Women are twice as likely as men to suffer from anxiety and depression. Depression is the second leading cause of global disability burden, and it is twice as common in women.

There are several factors that may contribute to the higher rates of depression and anxiety in women. One factor is gender-specific risk factors, such as gender-based violence, socio-economic disadvantage, income inequality, low social status, and responsibility for the care of others. Women's jobs are also more at risk from automation than men's jobs. These factors can cause significant social distress and contribute to the higher prevalence of depression and anxiety in women.

Biological factors may also play a role. Women experience hormonal changes throughout their lives, including menstruation, pregnancy, and menopause, which can impact their sleep cycles and increase their risk of sleep disturbances. Additionally, women are more likely to suffer from insomnia, which is strongly associated with depression and anxiety.

The higher rates of depression and anxiety in women have important implications for their overall health and well-being. It is crucial to address these mental health issues and provide support for women to improve their overall quality of life.

While the exact reasons for the gender disparity in depression and anxiety rates are not fully understood, it is clear that women's mental health is a critical area that requires further research and attention.

Increased risk of sleep disorders

Women are at an increased risk of developing certain sleep disorders, which can impact their overall sleep quality and quantity. A research review from 2014 revealed that women are 40% more likely to experience insomnia than men. They also have a higher risk of developing restless leg syndrome (RLS) and sleep apnea, both of which can significantly disrupt sleep.

Hormonal fluctuations during the premenstrual stage, pregnancy, perimenopause, and menopause can further contribute to sleep difficulties for women. For example, during menopause, women experience hormone changes that can negatively affect sleep quality, making them more prone to sleep disorders and chronic health conditions. Up to 67% of post-menopausal women develop obstructive sleep apnea (OSA), and they are also at a higher risk of developing thyroid disease, which can impact sleep.

Additionally, women are more likely to take on caregiving responsibilities and unpaid work, which can result in sleep disruption. A 2013 study found that women spent more time on unpaid labor, such as family caregiving and housework, which can interrupt their sleep patterns. As a result, they may need more sleep to compensate for these disruptions and maintain overall health.

More time spent on unpaid labour

Women spend significantly more time than men on unpaid care and domestic work, such as cooking, cleaning, childcare, eldercare, and farming. Globally, women spend 2.8 more hours than men on these tasks, and this figure is projected to only narrow slightly by 2050, with women still spending 2.3 more hours per day on unpaid care work. This disparity has several negative consequences for women. Firstly, it reduces their time available for paid labour, or forces them to work longer hours, combining both paid and unpaid labour. Secondly, it contributes to gender-based inequalities and stereotypes, with women being marginalized or adversely incorporated into the labour force. Finally, it results in a lack of recognition and undervaluation of women's unpaid work, which is essential for households and economies to function.

To address these issues, policies that provide services, social protection, and basic infrastructure are urgently needed. Additionally, promoting the sharing of domestic and care work between men and women, and creating more paid jobs in the care economy, can help accelerate progress towards women's economic empowerment.

The measurement of unpaid domestic and care work (UDCW) is crucial in understanding its impact. The International Labour Organization's (ILO) Statistical Standards and Methods Unit (SSMU) has developed practical time-use measurement tools to meet the growing demand for data on UDCW. These tools help quantify the significant contribution of UDCW to global GDP, which in some countries, exceeds 40% when given an equivalent monetary value.

By recognizing and valuing women's unpaid labour, we can work towards a more equitable distribution of domestic responsibilities and improve women's economic opportunities and social justice on a global scale.

Different views on sleep

While there is no specific research-backed number when it comes to how many hours of sleep women need compared to men, studies have shown that women tend to sleep more than men by 11 to 13 minutes. This difference in sleep duration between the sexes may be attributed to various factors, including biological, behavioural, and social differences. Here are some different views on why this sleep disparity exists:

Biological Factors

Women's sleep needs may be influenced by hormonal changes during different life stages, such as menstruation, pregnancy, and menopause. These hormonal fluctuations can impact their sleep quality and duration. For example, menopause can cause hot flashes and night sweats, disrupting sleep. Additionally, conditions like restless leg syndrome and sleep apnea are more prevalent in women, further affecting their sleep.

Behavioral Factors

Women are more likely to suffer from insomnia, depression, and anxiety, all of which can contribute to poor sleep quality and duration. Mental health and sleep are closely linked, and poor sleep can exacerbate these conditions, creating a cycle that impacts overall well-being.

Social Factors

Gender roles and societal expectations also play a part in the sleep disparity. Women are often the primary caregivers, taking on more unpaid labour and family responsibilities. This additional workload can lead to exhaustion and an increased biological need for sleep. Additionally, women may be more health-conscious and proactive about getting sufficient sleep, adopting habits like earlier bedtimes or napping to compensate for disrupted sleep.

Individual Variation

It is important to acknowledge that sleep needs vary among individuals, regardless of gender. Factors such as genetics, age, and lifestyle habits influence how much sleep each person requires. Therefore, while women may generally need slightly more sleep than men, individual sleep requirements can vary significantly.

In conclusion, the different views on sleep highlight the complex interplay of biological, behavioural, and social factors that contribute to the disparity in sleep duration between men and women. Further research is needed to comprehensively understand the roles of sex and gender in sleep needs and to develop effective strategies for improving sleep quality and overall health.

Frequently asked questions

On average, women sleep for 11 minutes more per night than men. However, this may vary depending on various factors, such as age, genetics, and individual sleep needs.

Women tend to experience more issues affecting their sleep quality and duration. These include biological factors, such as hormonal changes during menstruation, pregnancy, and menopause, as well as a higher risk of sleep disorders like insomnia, restless leg syndrome, and sleep apnea. Additionally, gender-based responsibilities, such as caregiving, can also impact women's sleep duration and quality.

Insufficient sleep, defined as less than seven hours per night for adults, can lead to increased risks of obesity, diabetes, high blood pressure, cardiovascular disease, and depression for both men and women. However, the health consequences may be more severe for women in some cases. For example, sleeping five hours or less per night is associated with a higher risk of high blood pressure in women but not in men.

If you regularly feel the need to take naps or experience burnout, it is likely that you are not getting enough sleep. Other signs include feeling sluggish or lacking energy to do the things you usually enjoy.

Here are some tips to enhance your sleep quality:

- Maintain a consistent sleep and wake-up time, even on weekends.

- Create a sleep-friendly environment by ensuring your room is quiet, dark, and comfortable.

- Avoid eating, caffeine, and alcohol close to bedtime.

- Reduce blue light exposure from screens at least two hours before bedtime.

- Engage in relaxing activities before bed, such as reading or taking a hot bath.

- Exercise regularly, preferably earlier in the day, and outdoors to expose yourself to natural light.
