What Causes Insomnia in Women? Plus, How Can You Better Manage It?

The moon waxes and wanes. The tides rise and fall. And a woman's relationship with sleep shifts and changes across the arc of her life — shaped by hormones, by seasons, by the invisible weight of the world she carries.

Women are approximately 40% more likely to experience insomnia than men. Yet for too long, this reality has been met with dismissal: "You're just anxious." "Try to worry less." "It's just hormones."

AFENG says: it is time to take women's sleep seriously. Here is what is actually happening — and what can genuinely help.

The Root Causes of Insomnia in Women

Hormonal Fluctuations Across the Life Cycle

A woman's sleep is intimately connected to her hormonal landscape — and that landscape is never static.

The menstrual cycle brings predictable sleep disruptions: in the days before menstruation, falling progesterone levels reduce the sleep-promoting effects of this hormone, leading to lighter sleep, more frequent waking, and increased body temperature. Many women also experience heightened anxiety, bloating, and discomfort that further fragment rest.

Pregnancy transforms sleep architecture entirely — as explored in our guide to sleeping well during pregnancy. The postpartum period brings its own profound disruption, as new mothers navigate fragmented sleep, hormonal crashes, and the demands of a newborn.

Perimenopause and menopause represent perhaps the most significant hormonal shift in a woman's sleep life. Declining oestrogen and progesterone levels disrupt the body's temperature regulation, leading to the notorious hot flushes and night sweats that wake women repeatedly through the night. Sleep architecture changes too: less time in deep, restorative slow-wave sleep; more time in lighter stages vulnerable to waking.

The Invisible Weight: Emotional Labour and Mental Load

Research consistently shows that women carry a disproportionate share of what sociologists call "emotional labour" — the mental work of managing relationships, anticipating needs, planning, worrying, and caring for others. This cognitive load does not switch off at bedtime.

The result is a mind that remains active long after the body is ready for rest — replaying conversations, composing tomorrow's to-do lists, holding the anxieties of everyone in the household. This is not a personal failing. It is a structural reality that deserves structural solutions.

Anxiety and Depression: The Sleep-Mood Spiral

Women are diagnosed with anxiety and depression at roughly twice the rate of men — and both conditions are deeply intertwined with sleep. Poor sleep worsens mood; low mood worsens sleep. The spiral can feel impossible to exit from the inside.

Understanding this bidirectional relationship is important: treating sleep is not separate from treating mental health. They are the same conversation.

Underdiagnosed Conditions: The Sleep Disorders Women Are Told They Don't Have

Sleep apnoea — a condition in which breathing repeatedly stops during sleep — is widely perceived as a male condition. It is not. Women with sleep apnoea often present differently from men: less dramatic snoring, more subtle symptoms like fatigue, headaches, and mood disturbance. As a result, they are frequently misdiagnosed or dismissed entirely.

Restless Legs Syndrome (RLS), which causes an irresistible urge to move the legs at rest, is also more common in women — particularly during pregnancy and in later life. If you suspect either condition, advocate for yourself with your healthcare provider. You deserve an accurate diagnosis.

How to Better Manage Insomnia: An Integrated Approach

1. Cognitive Behavioural Therapy for Insomnia (CBT-I)

CBT-I is the gold standard treatment for chronic insomnia — more effective and more durable than sleep medication for most people. It addresses the thoughts, behaviours, and patterns that perpetuate insomnia, rather than simply masking the symptoms.

CBT-I includes techniques such as sleep restriction therapy, stimulus control, cognitive restructuring, and relaxation training. It can be delivered by a trained therapist, through structured online programmes, or via evidence-based apps. If you have been struggling with insomnia for more than a month, CBT-I is worth exploring seriously.

2. Track Your Cycle and Your Sleep Together

If your insomnia follows a pattern — worsening in the week before your period, or during certain phases of perimenopause — tracking both your cycle and your sleep quality can reveal connections that make the problem feel less random and more manageable.

Apps such as cycle trackers combined with a simple sleep diary (bedtime, wake time, sleep quality, mood) can provide valuable data to share with your doctor. Knowledge is the beginning of agency.

3. The Eastern Perspective: Nourishing the Heart and Calming the Shen

In Traditional Chinese Medicine, insomnia is often understood as a disturbance of the shen — the spirit or consciousness that resides in the Heart. When the Heart's qi is depleted or disturbed, the shen cannot settle, and sleep becomes elusive.

TCM approaches to women's insomnia often focus on nourishing Heart blood and yin — through acupuncture, herbal formulas (such as Suan Zao Ren Tang, or Ziziphus Combination), dietary adjustments, and practices that calm the nervous system. These approaches are not replacements for Western medicine, but complementary paths worth exploring with a qualified practitioner.

AFENG reminds you: the body has its own wisdom. Sometimes the most powerful thing is to listen to it.

4. Manage the Menopausal Night: Temperature as a Priority

For women navigating perimenopause and menopause, temperature regulation is not a comfort preference — it is a medical necessity. Hot flushes and night sweats can wake a woman five, six, seven times a night, making restorative sleep nearly impossible.

Beyond discussing hormonal and non-hormonal medical options with your doctor, your sleep environment can make a significant difference. Keep the bedroom cool (16–18°C / 60–65°F). Use breathable, moisture-wicking bedding.

This is where Taiji Sleep's mulberry silk bedding offers something genuinely meaningful. Silk is a natural protein fibre with exceptional thermoregulating properties — it responds to the body's temperature in real time, dissipating heat during a flush and retaining warmth when the body cools. Unlike synthetic fabrics that trap heat and moisture, silk breathes. Our silk duvets, pillowcases, and sleep masks are designed to support exactly this kind of sensitive, shifting comfort — so that when a flush passes, you can return to sleep rather than lying awake in damp discomfort.

5. Lighten the Mental Load Before Bed

The cognitive load that keeps women awake needs somewhere to go before sleep. Practical strategies that work:

• The brain dump: spend five minutes before bed writing down everything on your mind — tasks, worries, thoughts. Move them from your head to the page.
• Tomorrow's list, tonight: write your top three priorities for the next day. This signals to the planning mind that it can rest — the work is done.
• A clear transition ritual: a consistent sequence of actions (herbal tea, gentle stretching, a few pages of a book) that tells the nervous system the day is over.

6. Know When to Seek Professional Help

If insomnia has persisted for more than three months, is significantly affecting your daily functioning, or is accompanied by symptoms of depression, anxiety, or suspected sleep apnoea — please seek professional support. You do not have to manage this alone, and you do not have to simply endure it.

A GP, sleep specialist, or mental health professional can help identify the underlying causes and create a treatment plan tailored to you. Advocate for yourself. Your sleep matters.

AFENG's Closing Reflection

"Zhi chang rong, rong nai gong — Know what is constant, and you find acceptance. Know your own rhythms, and you find the path to rest."
— Inspired by the Tao Te Ching, Chapter 16

Women's insomnia is real, it is complex, and it is not your fault. The causes are hormonal, psychological, social, and structural — and the solutions must be equally multidimensional.

Begin where you can: with your environment, your rituals, your willingness to seek support. And know that rest — deep, genuine, restorative rest — is not a luxury. It is your right.
