Do Women Require More Sleep Than Men? Unveiling the Truth
Explore the latest research on whether women truly need more sleep than men and understand the biological and social factors influencing sleep patterns.
While experts generally recommend equal sleep durations for men and women, new studies reveal that hormonal changes throughout a woman’s life can significantly influence her sleep quality and patterns.
Everyone deserves restorative sleep, but does the amount needed vary between individuals? Emerging evidence suggests women might face more frequent sleep disturbances compared to men due to a blend of biological, hormonal, and societal influences.
Recognizing these distinctions is vital for addressing sleep-related health challenges and enhancing sleep hygiene practices for all genders, ensuring everyone achieves the rest essential for optimal health.
The Importance of Inclusive Language
Research often differentiates participants by 'male' and 'female' or 'men' and 'women' to maintain clarity in clinical findings, though this binary language excludes transgender, nonbinary, and gender-diverse individuals, highlighting a gap in current studies.
How Much Sleep Do Women Actually Need?
Scientific consensus recommends that women aim for 7 to 9 hours of sleep nightly. However, studies indicate that exceeding 9 hours may increase risks for obesity and other health conditions.
Despite these guidelines, approximately 30% of adults do not consistently meet the recommended sleep duration, and even among those who do, nearly 40% of nights fall outside the ideal range. Only about 15% achieve 7 to 9 hours on at least five nights per week.
Interestingly, women tend to sleep longer than men on average, yet they still encounter challenges maintaining consistent sleep patterns.
What Causes These Differences?
Though sleep duration needs are similar, hormonal variations—especially involving oestradiol—affect women’s sleep efficiency and quality. These hormones regulate sleep consolidation and circadian rhythms, influencing sleep during key life phases such as:
- Puberty
- Menstruation
- Pregnancy
- Perimenopause
- Menopause
Hormonal Influences on Sleep
Fluctuating hormones can disrupt sleep throughout a woman’s life. Premenstrual phases often bring sleep difficulties, while pregnancy introduces fatigue, frequent nighttime urination, restless leg syndrome (RLS), and breathing issues.
During perimenopause and menopause, symptoms like hot flashes and night sweats commonly interrupt sleep.
Higher Risk of Sleep Disorders
A 2020 study revealed women are 58% more likely than men to suffer from insomnia, potentially leading to attempts to compensate with extra sleep. Women also face greater risks of sleep disturbances such as RLS and sleep apnea, which may increase their overall sleep requirements to feel rested.
The Impact of Unpaid Labor
After childbirth, women often experience greater sleep loss than men, with new mothers losing about 42 minutes more sleep per night compared to new fathers, highlighting social factors affecting sleep.
General Sleep Recommendations by Age
Sleep needs evolve with age due to hormonal changes, lifestyle, and health conditions. According to the CDC, average sleep requirements are:
- Birth to 3 months: 14–17 hours
- 4 to 11 months: 12–16 hours
- 1 to 2 years: 11–14 hours
- 3 to 5 years: 10–13 hours
- 6 to 12 years: 9–12 hours
- 13 to 18 years: 8–10 hours
- 18 to 64 years: 7–9 hours
- 65 years and older: 7–8 hours
Effective Strategies for Better Sleep
Quality sleep enhances mood, energy, productivity, and overall health. To improve sleep hygiene, consider these tips regardless of gender:
- Maintain a consistent sleep schedule, including weekends.
- Create a restful environment: quiet, dark, and comfortable with supportive bedding.
- Avoid heavy meals, caffeine late in the day, and alcohol before bedtime.
- Limit exposure to blue light from screens at least two hours before sleep.
- Engage in relaxing activities before bed, such as reading, meditation, or a warm bath.
- Incorporate regular exercise, but avoid vigorous activity close to bedtime.
- Consult a healthcare provider for persistent sleep difficulties or underlying health issues.
Conclusion
Men and women generally require similar sleep durations, but women’s sleep is often influenced by hormonal fluctuations during key life stages, leading to increased susceptibility to sleep disturbances like insomnia and sleep apnea.
Moreover, social responsibilities such as caregiving can further affect women’s sleep quality. Understanding these factors is essential to promote better sleep habits and ensure restorative rest for all individuals.
