Although sleep is important for everyone, research shows that women generally need more sleep than men.
Sleep is one of the foundations of our health. It restores the body, recharges the mind, and supports functions like memory, mood, learning, and immunity. Any healthcare provider, whether a doctor or a student in a nursing program like ABSN in Texas, will emphasize the importance of sleep.
According to Dutch guidelines, adults need an average of 7 to 9 hours of sleep per night to feel truly rested — for older adults, this norm is 7 to 8 hours. This is stated in the NHG Standard Sleep Problems and Sleep Medications. Yet research shows that women generally sleep slightly longer than men. Why exactly is that? Does it have to do with biological differences? And what does that mean practically for women in their daily lives?
In this article, we explore why women generally need more sleep, what the consequences of chronic sleep deprivation are, and how women can improve their sleep quality.
The 5 Key Takeaways
- There are biological reasons why women often crave more sleep than men.
- Sleep deprivation has a stronger effect on women’s mood and metabolism.
- The hormonal cycle affects women’s sleep quality throughout the month.
- Women sleep deeper, but also experience more frequent nighttime disruptions.
- Practical adjustments are possible to sleep better and wake up refreshed.
Why Is Sleep So Important?
Before we discuss differences between men and women, it’s good to first look at why sleep is essential for everyone. Sleep supports both physical and mental recovery. During deep sleep, the body repairs itself, muscles relax, and waste products are cleared from the brain. Without enough sleep, this recovery is disrupted, which can lead to concentration problems, mood swings, memory complaints, and even physical issues.
Sleep is also crucial for immunity. Long-term sleep deprivation increases the risk of conditions like heart disease, diabetes, and obesity. At the same time, it becomes harder for the body to fight infections.
Beyond these physical effects, sleep also influences your emotional balance. Sleep deprivation can intensify feelings of irritability, restlessness, or sadness. Those who sleep poorly for extended periods also have a higher risk of developing mental health issues.
Biological Differences: Hormones and Sleep
The fact that women need slightly more sleep on average than men seems partly explained by biological factors. Hormonal processes play a major role in regulating sleep, and women go through different hormonal phases throughout their lives that affect sleep.
For example, the menstrual cycle can affect sleep. In the days before menstruation, fluctuations in progesterone and estrogen often cause fatigue or restless sleep. Some women notice they need extra rest during this time.
During pregnancy too — especially in the first trimester — many women feel extra tired. This is partly due to an increase in the hormone progesterone, which has a calming effect. At the same time, physical changes like a growing belly, back pain, or frequent nighttime bathroom trips cause interrupted sleep.
As menopause approaches, hormone levels drop significantly. This can further disrupt sleep. Night sweats, hot flashes, and restless dreams make it harder to sleep through the night, affecting sleep quality.
Glossary
- Progesterone: Sex hormone involved in the menstrual cycle and pregnancy; it often has a calming effect.
- Estrogen: Hormone that plays a role in fertility and sleep regulation, and decreases during menopause.
- Deep sleep: Restorative sleep phase in which the body physically recovers and energy is replenished.
- Sleep deprivation: Long-term or recurring situation in which someone sleeps less than the body needs for recovery.
Differences in Sleep Patterns Between Men and Women
The difference in sleep between men and women isn’t just about hormones, but also how sleep itself is structured. Research shows that women have different sleep architecture than men. Sleep architecture refers to the composition of different sleep stages: from light sleep and deep sleep to REM sleep, where dreaming occurs.
On average, women spend more time in deep, restorative sleep — also called slow-wave sleep. This phase is important for physical recovery and mental sharpness. At the same time, women tend to experience more nighttime disruptions. Think of hormonal fluctuations, sleep disorders like insomnia, or the pressure of caregiving and stress. As a result, they sometimes get more sleep, but that sleep isn’t always as refreshing.
What Sleep Deprivation Does to Women
Although ideal sleep duration varies per person, women who consistently get too little sleep often face significant consequences.
Research shows that women are more sensitive to the negative effects of sleep deprivation on their metabolism and cardiovascular system. Chronic sleep deprivation increases women’s risk of high blood pressure and reduced insulin sensitivity.
Sleep is also crucial for memory and the ability to process information. Poor sleep can make it harder to concentrate or think clearly. This can lead to frustration, reduced productivity, or mistakes at work or in daily life.
Women also more often experience sleep problems linked to mental health issues like anxiety or depression. Too little sleep can affect mood and emotional resilience. Those who sleep poorly for long periods become more easily overstimulated or tense.
Additionally, sleep influences hormones that regulate hunger, stress, and energy. With sleep deprivation, this balance is disrupted, which can lead to weight gain, increased appetite, or mood swings. This reinforces the vicious cycle of fatigue and overwhelm.
Practical Tips for Better Sleep
Maintain a Consistent Sleep Schedule
By going to bed and waking up at the same time each day, you align your biological clock with a natural rhythm. Your body gets used to it, making it easier to fall asleep and wake up.
Wind Down Before Bed
A consistent evening routine helps you end the day calmly. Think of reading, meditation, or gentle stretching. Avoid stimuli like bright screens or exciting shows right before sleep.
Create a Comfortable Sleep Environment
A cool, dark, and quiet room promotes sleep. A good mattress and comfortable pillow make a difference. It’s best to avoid electronics in the bedroom, as they often cause unnoticed restlessness.
Exercise Regularly
Adequate physical activity during the day contributes to deeper sleep. Pay attention to timing: intense exercise right before bed can backfire because your body is still too active.
Manage Stress Consciously
Stress is a common cause of sleep problems. Breathing exercises, mindfulness, or conversations with a coach or therapist can help release tension and sleep more peacefully.
Be Mindful of What You Eat and Drink
Heavy meals, caffeine, or alcohol right before bed can disrupt sleep. Your body stays active when you’re trying to rest. A light, nutritious dinner often works better.
Sleep Is Not a Luxury, But a Basic Need
Rest is essential for everyone’s health, and women seem to need slightly more of it on average. While society often demands much from women, it’s important to realize that sleep is not a sign of weakness — it’s a prerequisite for long-term well-being.
Those who consciously make room for good sleep habits often notice that energy, concentration, and mood improve. Good sleep is not a quick fix, but an investment in yourself.

Frequently Asked Questions
Why do women sleep longer on average than men?
This is partly due to hormonal fluctuations, different sleep structure, and a greater chance of nighttime disruptions. As a result, women need more recovery time to feel rested.
What is the effect of sleep deprivation on women?
Sleep deprivation affects women’s memory, mood, hormone balance, and metabolism. It also increases the risk of stress-related issues, weight gain, and mood disorders.
How much sleep do women need?
Although it varies per person, research shows that women need slightly more than seven hours of sleep per night on average — sometimes up to nine hours, depending on age and life stage.
Why is sleep disrupted during menstruation or menopause?
Hormone changes like drops in progesterone and estrogen can lead to restless sleep, fatigue, and night sweats. This often occurs in women during their reproductive years or transition phase.
How can women improve their sleep?
A consistent sleep schedule, relaxation before bed, a quiet sleep environment, and limiting caffeine or alcohol can contribute to deeper, more restorative sleep.
