Causes of Insomnia in Women: Why It Affects Us More at Every Stage of Life

Women are 1.5 to 2 times more likely to experience insomnia than men, according to numerous epidemiological studies. This difference is not a coincidence: it can be explained by specific hormonal, physiological, and psychosocial mechanisms that evolve throughout a woman’s life — from menstruation to menopause, including pregnancy and the postpartum period.

The Link Between Female Hormones and Sleep

Estrogen and progesterone have a direct effect on the brain centers that regulate sleep. Progesterone has a natural sedative effect (it stimulates GABA receptors, the brain’s main inhibitory neurotransmitter), while estrogen influences the production of serotonin and melatonin. Any fluctuation in these hormones can therefore disrupt sleep.

Causes of Insomnia at Different Stages of Life

1. Before and During Your Period (Premenstrual Syndrome)

During the week before menstruation, the sharp drop in progesterone reduces its natural sedative effect. Combined with premenstrual syndrome (PMS) symptoms — cramps, bloating, irritability, and anxiety — this explains why many women sleep less well just before their period.

2. During Pregnancy

Insomnia affects up to 78% of pregnant women, particularly during the first and third trimesters. The causes are numerous: nausea, frequent urination, acid reflux, lower back pain, anxiety about childbirth, and physical discomfort caused by the growing abdomen.

3. The Postpartum Period

After childbirth, the dramatic drop in estrogen and progesterone, combined with nighttime awakenings for breastfeeding and the stress associated with new parenthood, can frequently cause insomnia in new mothers.

4. Perimenopause and Menopause

This is the period when insomnia tends to be most frequent and severe in women. The decline in estrogen can cause nighttime hot flashes (night sweats), which lead to sudden awakenings and disrupt sleep architecture. Up to 60% of menopausal women report significant sleep problems.

Non-Hormonal Causes of Insomnia in Women

Stress and Anxiety

Women statistically report higher levels of stress and anxiety, often related to mental load (managing the household, children, and work). This mental load can activate the sympathetic nervous system in the evening, making it harder to fall asleep.

Depression

Depression affects women twice as often as men, and insomnia is one of its core symptoms — either as difficulty falling asleep or waking too early in the morning.

Restless Legs Syndrome

This neurological disorder, which is twice as common in women, causes an irresistible urge to move the legs in the evening, significantly delaying sleep onset. It is often associated with iron deficiency.

Mental Load and Domestic Work

Even when working full-time, women still statistically take on a greater share of household and parenting responsibilities. This can reduce the amount of time available for sleep and increase evening stress levels.

Thyroid Disorders

Both hyperthyroidism and hypothyroidism, which are more common in women, can disrupt sleep: hyperthyroidism through agitation and an accelerated metabolism, and hypothyroidism through persistent fatigue and disruptions to circadian rhythms.

The Consequences of Untreated Chronic Insomnia

• Increased risk of depression and anxiety

• Weight gain and insulin resistance

• Weakened immune system

• Increased cardiovascular risk

• Problems with concentration and memory

• Accelerated skin aging

Solutions and Best Practices

Sleep Hygiene

• Maintain regular bedtimes and wake-up times, even on weekends

• Keep your bedroom cool, dark, and quiet

• Avoid screens for at least 1 hour before bedtime

• Limit caffeine after 2 p.m. and alcohol in the evening

• Exercise regularly, but avoid intense physical activity right before bedtime

Approaches Based on the Cause

• Period-related insomnia: magnesium, gentle physical activity, and managing premenstrual stress

• Pregnancy-related insomnia: pregnancy pillow, side-sleeping positions, and relaxation techniques

• Menopausal insomnia: hormone replacement therapy to be discussed with a gynecologist, along with techniques to manage hot flashes

• Cognitive Behavioral Therapy for Insomnia (CBT-I): the first-line treatment for chronic insomnia, highly effective and without medication-related side effects

When Should You See a Doctor?

You should consult a doctor if insomnia persists for more than 3 months, occurs several times a week, and affects your daytime quality of life (fatigue, irritability, or difficulty concentrating).

Conclusion

Insomnia in women is not inevitable. It can be explained by specific hormonal and psychosocial mechanisms that can be identified and treated. Appropriate medical support at every stage of life can help women regain restorative, quality sleep.
