Sleep And Gender: Why Women Need More Shut-Eye

do women need mkre sleep than men

There is some evidence to suggest that women need more sleep than men. While the difference is small—sources suggest between 10 and 20 minutes—it can have a significant impact on a woman's overall health and wellness. Research has shown that women are more likely to experience sleep disorders such as insomnia, depression, and restless leg syndrome, which can all contribute to sleep disruption. Hormonal changes during menstruation, pregnancy, and menopause can also impact a woman's sleep quality. Additionally, gender-based responsibilities, such as caregiving, can affect the duration and quality of sleep for women. While the recommended amount of sleep for adults is 7 to 9 hours, women may need slightly more to feel rested and refreshed.

Sleep disorders

Women are nearly twice as likely as men to experience anxiety and depression, which are linked to insomnia. They may also be more prone to delayed diagnoses and misdiagnoses due to stereotypes that persist even among medical professionals.

Other sleep disorders that affect women include nocturnal sleep-related eating disorder (NS-RED), in which individuals eat in their sleep and have no recollection of it upon waking up, and REM behaviour disorder, which involves the physical enactment of dreams.

Biological differences, such as hormonal changes and fluctuations, also contribute to the gender gap in sleep duration and quality. Women tend to take longer to fall asleep and spend more time in deep sleep than men. However, this changes during menopause, when women take longer to fall asleep and spend less time in deep sleep.

The impact of gynecological factors, such as the menstrual cycle, pre-menstrual symptoms, and menopause on sleep, are well-documented. Premenstrual complaints, irregular menstrual cycles, and the use of contraceptives have all been associated with sleep disturbances in women.

During pregnancy, hormonal adjustments, physical discomfort, anxiety, and fetal movements can disrupt sleep. Sleep problems may continue into the postpartum period when hormone levels drop and the demands of caring for a newborn arise.

Perimenopause and menopause can also worsen sleep problems due to hormonal alterations and other factors that directly or indirectly lead to or aggravate sleep issues. These include impaired temperature regulation, depression, insomnia, and pain.

In addition to hormonal changes, social, work, family, and domestic life factors can also negatively impact women's sleep. The increased participation of women in the workforce has not been accompanied by a decrease in domestic and family responsibilities, resulting in chronic sleep deprivation for many women.

Menstruation

Hormonal changes are the primary driver of sleep disturbances during menstruation. Specifically, fluctuations in estrogen and progesterone levels impact the body's temperature control, affecting sleep quality. Additionally, people with PMDD experience reduced melatonin production and blunted responses to melatonin supplements during this time, further contributing to sleep difficulties.

The impact of menstruation on sleep can manifest in various ways. Some women may experience insomnia, finding it harder to fall asleep or stay asleep. They may also have restless sleep in the days leading up to their period and feel sleepier during the day. Research shows that the amount of REM sleep, the stage when we dream, decreases during this part of the menstrual cycle.

To manage sleep disturbances related to menstruation, several strategies can be employed:

  • Keeping a sleep diary for three months or more can help confirm if sleep problems are linked to the menstrual cycle.
  • Getting more sleep just before the expected period can help mitigate the impact of sleep disturbances.
  • Reducing caffeine and alcohol intake, especially a few hours before bedtime, can improve sleep quality.
  • Maintaining a healthy diet with less sugar and salt and more calcium is recommended.
  • Increasing exposure to outdoor light before and during the premenstrual phase may be beneficial.
  • For those with PMS, taking melatonin supplements may help improve sleep, but this should be discussed with a healthcare provider.
  • If PMS symptoms significantly impact quality of life, consulting a healthcare professional can provide additional treatment options to alleviate symptoms and improve sleep.

Pregnancy

Pregnant women are also more likely to experience depression, sleep apnea, pain, and incontinence, all of which can disrupt their sleep. These issues can persist 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.

To maintain good sleep hygiene during pregnancy, it is recommended to avoid alcohol and caffeine, create a sleep-friendly environment, engage in daily exercise, maintain a sleep schedule, and manage mental health through meditation, journaling, or therapy.

Menopause

While there is no research-backed number of hours of sleep women need compared to men, studies have shown that women tend to sleep more than men. Women are also more susceptible to sleep disorders, such as insomnia, restless leg syndrome, and sleep apnea. Hormonal changes during menstruation, pregnancy, and menopause can also impact a woman's sleep.

  • Hot flashes and night sweats: Hot flashes are common during menopause, and when they occur at night, they can cause night sweats, disrupting sleep. Research suggests that the changes in the brain leading to hot flashes may also trigger awakenings.
  • Sleep apnea: The risk of developing sleep apnea increases during menopause. This sleep disorder can cause pauses in breathing, reducing sleep quality and leading to daytime sleepiness.
  • Hormonal changes: During menopause, the body produces less estrogen and progesterone, which can affect thermoregulation, mood, metabolism, and the circadian rhythm, all of which can impact sleep.
  • Mental health: Menopause is associated with anxiety and depression, which are risk factors for poor sleep.
  • Restless legs syndrome (RLS): More than half of post-menopausal people experience RLS, which can make it difficult to fall asleep and lead to insomnia.

To manage sleep during menopause, it is recommended to:

  • Optimize the sleep environment by keeping the bedroom cool, dark, and quiet.
  • Manage stress with techniques like mindfulness meditation.
  • Exercise regularly to improve sleep quality and support heart health.
  • Avoid alcohol, caffeine, and tobacco, as these substances can interfere with sleep and intensify hot flashes.
  • Try cognitive behavioral therapy for insomnia (CBT-I) to address menopause-related sleep problems and reduce irritation associated with hot flashes.

Gender-based responsibilities

Several factors contribute to the gender-based differences in sleep requirements, with women typically needing more sleep than men. One key aspect is the distribution of unpaid labour and caregiving responsibilities, which often falls disproportionately on women.

A 2013 study found that women spend less time in the workforce and more time on unpaid labour, such as family caregiving and housework. While employment is associated with reduced sleep, allowing women more time for sleep, their sleep is often interrupted due to caregiving duties. Women are more likely to wake up to care for others in the home, disrupting their sleep quality. This dynamic is particularly evident during the postpartum period when women experience sleep issues due to hormonal changes, newborn care, and breastfeeding.

Additionally, gender norms and societal expectations influence sleep patterns. Men tend to spend more time on leisure activities and work outside the home, while women are more likely to nap during the day and experience nighttime sleep interruptions, especially with young children. These "gendered time tradeoffs" contribute to women's longer total sleep time, which may be compensating for fragmented sleep.

Furthermore, women's higher stress levels, often resulting from their multiple responsibilities, can also impact their sleep. They may experience higher stress due to their caretaker roles and the resulting multitasking, which has been linked to sleep problems.

Frequently asked questions

Research suggests that women tend to sleep slightly longer than men, by around 11 to 20 minutes. However, there is no evidence that biology is a factor.

Women are more likely to experience sleep disorders, such as insomnia, depression, and restless leg syndrome. They are also more susceptible to anxiety and are more likely to have interrupted sleep due to gender-based responsibilities, like caregiving. Hormonal changes during menstruation, pregnancy, and menopause can also impact sleep quality.

On average, women need 7 to 9 hours of sleep per night to feel rested and refreshed. However, this can vary depending on their physical condition and life stage. For example, pregnant women may need 8 to 10 hours, while older women may require less sleep.
