Sleep Needs: Gender Differences And Their Reasons

do women need more sleep than men pubmed

Sleep is an essential part of our lives, and most adults need around seven to nine hours of sleep per night. However, research suggests that women tend to need more sleep than men. On average, women sleep for about 11 minutes longer than men, but why is this the case? Several factors, including hormonal changes, mental health issues, and a higher risk for specific sleep disorders, can impact a woman's sleep needs. These factors include hormonal changes during menstrual cycles, pregnancy, and menopause, which can cause insomnia, night sweats, and hot flashes. Women are also more likely to experience depression and anxiety, and they often have additional responsibilities like childcare and household duties, which can increase stress levels and make it challenging to relax before bed. Understanding these gender differences in sleep patterns is crucial for improving sleep quality and overall health and well-being for both men and women.

Women need 11 more minutes of sleep than men

On average, women need 11 more minutes of sleep than men. While this may not apply to everyone, it is indicative of the differences between the sexes and their sleep patterns. Sleep disorders specialist Michelle Drerup, PsyD, explains that women tend to have more issues affecting their sleep, and therefore require more of it to compensate for poor-quality sleep.

There are several reasons why women may need more sleep than men. Firstly, women are more likely to experience depression and anxiety, which are associated with insomnia. Women are twice as likely as men to suffer from these conditions, which can cause difficulty falling or staying asleep, and daytime sleepiness.

Secondly, hormonal changes can affect women's sleep cycles and increase their risk of sleep disturbances. Women experience hormonal changes during monthly menstrual cycles and significant life stages such as pregnancy, breastfeeding, perimenopause, and menopause. Menopause, in particular, can disrupt sleep by increasing the time it takes to fall asleep and reducing the amount of deep sleep.

Thirdly, women are more prone to insomnia, which may explain why they need more sleep overall. Insomnia can be caused by various factors, including hormonal changes, stress, and sleep environment.

Additionally, gender-based responsibilities, such as caregiving and household labour, can also impact women's sleep duration and quality. Women are more likely to wake up during the night to take care of children or elderly parents, disrupting their sleep.

While the exact amount of sleep needed varies from person to person, addressing sleep issues and prioritising quality sleep is essential for maintaining good health.

Women fall asleep faster and spend more time in deep sleep

Women's sleep patterns differ from men's in several ways. Studies have shown that women fall asleep faster and spend more time in deep sleep, indicating a greater need for sleep. These differences may be influenced by biological and gender-based factors.

Biologically, hormonal changes play a significant role in women's sleep patterns. Fluctuating hormones during menstrual cycles, pregnancy, and menopause can cause insomnia, night sweats, and hot flashes, resulting in sleep disturbances. For instance, during menopause, women experience disrupted sleep due to hot flashes and an increased risk of developing sleep apnea. Additionally, conditions like restless leg syndrome and sleep apnea can be aggravated by pregnancy, further impacting sleep quality.

Gender-based differences also contribute to women's sleep patterns. Women are more likely to experience depression and anxiety, which are strongly associated with insomnia. They also tend to have more responsibilities like childcare and household duties, leading to added stress and difficulty unwinding before bed. These factors can impact their overall sleep quality.

The impact of these biological and gender-based differences is evident in women's sleep behaviour. Women are more likely to nap during the day and report more sleep challenges than men. They also tend to fall asleep faster and spend a greater proportion of their sleep in deep sleep.

While the reasons behind these differences are multifaceted, the evidence suggests that women's sleep needs are unique and require further exploration to improve the diagnosis, treatment, and prevention of sleep disorders.

Insomnia, depression, and hormone changes disrupt women's sleep

Insomnia is much more common in women than in men. This can be caused by a variety of reasons, including psychological, social, and physiological factors. Women are more likely to experience insomnia, depression, and anxiety, all of which are strongly associated with insomnia.

Insomnia in Women

Women are 40% more likely to experience insomnia than men. Insomnia is a medical condition in which insufficient sleep causes a significant decline in daytime performance and functioning. Women frequently report subjectively poorer sleep than men. They are more likely to report difficulty staying asleep, feeling unrefreshed in the morning, and excessive daytime sleepiness.

Depression and Anxiety in Women

Women are nearly twice as likely to be diagnosed with anxiety and depression, two conditions strongly associated with insomnia. Mental health and sleep are closely linked, but experts still consider the relationship a "chicken-or-the-egg" scenario. Poor sleep can affect mental health, but depression also makes people more likely to have trouble sleeping.

Hormone Changes in Women

Hormones may be another reason for differing sleep needs. The sleep-wake cycle is ruled by hormones, which affect when a person feels tired, when they feel alert, and when they feel hungry. Women experience hormonal changes each month and over the course of their lifetimes, which impact their circadian rhythms and create a greater need for sleep.

Menstruation

One-third of people who menstruate have trouble sleeping due to cramps, headaches, and bloating. They report higher levels of daytime sleepiness, tiredness, and fatigue.

Pregnancy

During pregnancy, women may develop restless legs syndrome, a condition that makes it harder to fall asleep. They are also more likely to experience depression, sleep apnea, pain, and incontinence, which disrupt their sleep. These sleep issues can persist into the postpartum period.

Menopause

During menopause, up to 85% of women experience hot flashes. When these occur at night, women wake up in a sweat, disrupting their sleep. The risk of developing sleep apnea also increases during menopause.

Gender-based responsibilities, like caregiving, affect women's sleep duration

Women are more likely than men to wake up to take care of others in the home, a task which disrupts their sleep. Sleep disruptions can reduce overall sleep quality. This is supported by a study of 26 working-age UK couples with children, which showed that women were more likely to rise from sleep to do emotional and other care work.

Women are also more likely to be the ones to reduce their paid work when unpaid work and caregiving responsibilities are highest. This means that women may face decreasing time for sleep relative to men.

Additionally, women are more likely to nap during the day, which suggests their longer total sleep time may be misleading since some of it takes place during the day. Naps can also make nighttime sleep less restful.

Women are twice as likely to have anxiety and depression, which are associated with insomnia

Women are twice as likely as men to experience anxiety and depression, which are associated with insomnia. This means that women are more vulnerable to sleep problems. The same brain chemicals that regulate sleep are also involved in regulating mood disorders. Women are also more likely to experience insomnia due to the hormonal changes they undergo during puberty, menstruation, pregnancy, and menopause.

Hormones play a crucial role in sleep-wake cycles, affecting when a person feels tired, alert, and hungry. Women's hormonal changes each month and throughout their lives impact their circadian rhythms and create a greater need for sleep. For example, during menopause, up to 85% of women experience hot flashes that disrupt their sleep.

Additionally, women often shoulder a heavier burden of caregiving responsibilities, which can further disrupt their sleep. Juggling work and caregiving reduces sleep time and contributes to sleep disruptions, affecting overall sleep quality.

The link between mental health and sleep is complex. Poor sleep can impact mental health, but depression also makes it harder to fall and stay asleep. This interconnection highlights the need to address both sleep and mental health issues for effective treatment.
