Sleep Patterns: Why Women Need More Shut-Eye Than Men

do womem need more sleep than men

There is some evidence to suggest that women need more sleep than men. Research indicates that women tend to sleep longer than men, but the difference is fairly small, ranging from 11 to 20 minutes per night. While there is no biological evidence to explain this difference, various factors contribute to women's sleep patterns and requirements. These include hormonal changes, physical changes, and activity levels.

Sleep disorders

Insomnia is characterised by difficulty falling or staying asleep, resulting in a lack of refreshment upon waking and difficulties functioning during the day. It is the most common sleep disorder and is often linked to anxiety and depression, conditions that are nearly twice as prevalent in women.

Restless legs syndrome (RLS) causes unpleasant sensations in the legs when lying down, along with an uncontrollable urge to move them. RLS can make it challenging for women to fall asleep and may lead to daytime sleepiness, mood swings, anxiety, and depression, further exacerbating sleep problems. The risk of RLS is higher in women with multiple children and increases significantly from pregnancy to menopause.

Sleep apnea is a disorder characterised by temporary pauses in breathing during sleep, resulting in loud snoring, choking, and gasping. While it is twice as common in men, the risk for women increases after menopause due to hormonal changes and increased abdominal fat.

Other sleep disorders that affect women include nocturnal sleep-related eating disorder (NS-RED), where individuals eat in their sleep with no recollection of doing so, and REM behaviour disorder, which involves physical enactment of dreams. Additionally, conditions like migraine, pain, and anxiety can also contribute to sleep disturbances in women.

Biological differences, hormonal fluctuations, and social factors all play a role in the higher prevalence of sleep disorders among women. Seeking medical advice and adopting better sleep habits can help manage these conditions and improve sleep quality.

Menstruation, pregnancy and menopause

Fluctuating hormones during menstruation, pregnancy, and menopause can make it difficult for women to get a good night's sleep.

Menstruation

Hormone changes during the menstrual cycle are associated with changes in sleep patterns. Women often report poorer sleep quality and greater sleep disturbance during the premenstrual week compared to other times in their cycle. They may also experience more disturbing dreams, sleepiness, fatigue, decreased alertness, and concentration during this time.

Pregnancy

Pregnancy is a time when women need to pay particular attention to their health, as any health issues may impact the development and growth of the baby. Hormonal changes during pregnancy can cause sleep disturbances, with many pregnant women feeling tired during the first few months and again towards the end of their pregnancy. As the pregnancy progresses, women tend to have less deep sleep and wake up more often during the night. They may also experience frequent urination, which can cause multiple nighttime trips to the bathroom. Some women may also develop insomnia, restless leg syndrome, or sleep apnea during pregnancy, which can further impact their sleep quality.

Menopause

Menopause is often a time when women experience other significant changes in their lives, such as caring for aging parents or supporting children as they transition to adulthood. Symptoms of menopause, such as hot flashes, night sweats, and changes in mood, can also disrupt sleep. The risk of developing sleep apnea also increases after menopause.

Hormone changes

Hormones play a significant role in the sleep differences between men and women. The sleep-wake cycle is governed by hormones, which affect when a person feels tired, alert, or hungry. Women experience hormonal changes each month and throughout their lives, which impact their circadian rhythms and create a greater need for sleep.

Menstruation is one such hormonal change that can disrupt sleep. One-third of people who menstruate have trouble sleeping due to cramps, headaches, and bloating, resulting in higher levels of daytime sleepiness, tiredness, and fatigue. Hormonal fluctuations during the premenstrual stage can also make it challenging to get a good night's sleep.

Pregnancy is another period when hormonal changes can affect sleep. 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. These sleep issues can persist into the postpartum period when hormone levels drop, and they have to care for a newborn with an irregular sleep cycle, leading to even more daytime sleepiness.

Menopause is a significant hormonal transition that can impact sleep. Up to 85% of women experience hot flashes, and when these occur at night, they can disrupt sleep. Additionally, the risk of developing sleep apnea increases during menopause, causing pauses in breathing that interfere with sleep quality. As a result, women with sleep apnea may feel less refreshed upon waking and experience tiredness and excessive sleepiness during the day.

Hormonal changes throughout a woman's life, including menstruation, pregnancy, and menopause, can impact their sleep patterns and overall sleep needs. These changes can create a greater need for sleep and contribute to sleep disorders, such as insomnia and restless leg syndrome, which are more prevalent in women.

Gender-based responsibilities

Several studies have found that women tend to sleep longer than men, but the difference is fairly small, ranging from 11 to 20 minutes. This difference in sleep duration can be attributed to various gender-based responsibilities and societal expectations that affect women's sleep more than men's.

Firstly, women are often the primary caregivers in households, taking on more unpaid labour such as family caregiving and housework. This additional workload can lead to increased stress and fatigue, resulting in a greater need for sleep. Additionally, women are more likely to have their sleep interrupted during the night to care for others, which can further contribute to their longer total sleep time.

Secondly, societal expectations and gender norms influence the distribution of work and social responsibilities between men and women. Women are often expected to take on the majority of domestic tasks and childcare, while also managing their careers. This "second shift" of unpaid labour can leave women with less time for leisure and self-care, impacting their sleep duration and quality.

Furthermore, gender stereotypes and expectations can affect women's ability to prioritise their sleep. Women may feel pressured to always put others' needs before their own, including their children, partners, or employers. This can result in them sacrificing their sleep to fulfil these perceived obligations.

Additionally, women are more likely to experience sleep disruptions due to biological factors such as menstruation, pregnancy, and menopause. These hormonal changes can cause physical and emotional symptoms that impact sleep quality and duration. For example, during menstruation, women may experience cramps, headaches, and bloating that interfere with their sleep. Pregnancy can bring about restless leg syndrome and incontinence, while menopause can lead to hot flashes and night sweats, all of which can disrupt sleep.

Lastly, gender-based responsibilities and societal expectations can influence women's sleep patterns and behaviours. Women are more likely to nap during the day, which may be a way to compensate for fragmented sleep at night. Napping can add to total sleep time but can also impact the restfulness of nighttime sleep.

Sleep duration

There is no consensus on the number of hours of sleep women need compared to men. However, adults of any gender need seven or more hours of sleep a day for optimal health. Research has shown that women tend to sleep more than men, but the difference is minimal, ranging from 11 to 20 minutes. This fluctuation in sleep duration is influenced by various factors, including biological and gender-based differences, which impact women's sleep quality and quantity.

Biological factors, such as hormonal changes, play a significant role in women's sleep patterns. Hormones like testosterone and oestrogen govern the sleep-wake cycle, and women experience hormonal fluctuations throughout their lifetimes, including menstruation, pregnancy, and menopause. During menstruation, one-third of people who menstruate have trouble sleeping due to physical discomfort and emotional changes. Pregnancy can also increase the likelihood of developing restless leg syndrome and sleep apnea, both of which disrupt sleep. Additionally, the hormonal changes during menopause can cause hot flashes and night sweats, further interrupting sleep.

Gender-based differences, such as caregiving responsibilities and social expectations, also contribute to the variation in sleep duration. Women are more likely to engage in unpaid labour, including family caregiving and housework, which can disrupt their sleep. They are also more prone to sleep disorders like insomnia, anxiety, and depression, which are strongly associated with insomnia. These factors collectively contribute to the slightly longer sleep duration observed in women compared to men.

While the difference in sleep duration between women and men is not significant, it is important to recognise these gender-based and biological differences to promote better sleep hygiene and overall health.

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 insomnia, depression and anxiety, all of which are associated with disrupted sleep. Hormonal changes during menstruation, pregnancy and menopause can also impact sleep. Additionally, women are more likely to take on caregiving responsibilities, which can interrupt sleep.

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

Women who are struggling to get enough sleep should aim to get regular exercise, stick to a consistent sleep schedule, limit caffeine and alcohol intake, and improve their sleep environment.
