Why Women Often Face a More Restless Night

It’s a common lament heard in many households: women often report struggling with sleep more than men. While the idea might seem anecdotal, scientific research consistently supports this observation. Indeed, studies reveal that biological sex plays a significant role in how well a person sleeps, with sleep problems appearing more prevalent and sometimes more severe in women. But why is this the case? The answer lies in a complex interplay of hormonal fluctuations, unique life stages, differing presentations of sleep disorders, and even societal roles.

The Hormonal Rollercoaster: A Key Driver of Female Sleep Patterns

One of the most significant contributors to the disparity in sleep quality between men and women is the ever-shifting landscape of female hormones. Unlike men, women experience profound hormonal changes throughout their lives, each with the potential to disrupt sleep.

• The Menstrual Cycle: From puberty onwards, the monthly ebb and flow of oestrogen and progesterone can significantly impact sleep. Many women report increased difficulty falling and staying asleep, particularly in the days leading up to their period (the late luteal phase) when progesterone levels drop dramatically. This hormonal shift can affect the body’s temperature regulation and even reduce the amount of restorative REM sleep. For those experiencing premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD), symptoms like anxiety, cramps, and headaches further exacerbate sleep difficulties.
• Pregnancy: The nine months of pregnancy bring a cascade of hormonal shifts, notably increased levels of progesterone. While progesterone can have a mildly sedative effect, other factors often override this benefit. Physical discomfort (growing belly, back pain), frequent urination, restless legs syndrome, heartburn, and heightened anxiety all conspire to make a good night’s sleep a rare luxury for many expectant mothers. The third trimester, in particular, often sees significant sleep fragmentation.
• Perimenopause and Menopause: As women approach and enter menopause, oestrogen and progesterone levels fluctuate erratically and eventually decline. This hormonal upheaval is a major culprit behind common sleep disturbances like hot flashes and night sweats, which frequently interrupt sleep. Lowered hormone levels can also lead to increased anxiety and irritability, further hindering relaxation and sleep onset. Research also suggests that the protective effect of these hormones against certain sleep disorders, like sleep apnoea, diminishes after menopause, leading to an increased risk for women. For more in-depth information on managing sleep during this transition, the NHS offers guidance on menopause symptoms.

Beyond Hormones: Other Contributing Factors

While hormones are central, they are not the sole determinants of women’s sleep struggles. Other physiological and lifestyle factors also play a crucial role:

• Mental Health: Women are statistically more prone to mood disorders such as anxiety and depression– conditions that are intrinsically linked to sleep disturbances. The same neurochemicals in the brain that regulate mood also play a role in sleep, creating a vicious cycle where poor sleep can worsen mental health and vice-versa. If you’re struggling with mental health impacting your sleep, resources like the Mind charity can provide support.
• Sleep Disorders with Different Presentations: While conditions like sleep apnoea have historically been considered more prevalent in men, they are increasingly recognised in women, though their symptoms can differ. Men with sleep apnoea often present with loud snoring and choking episodes, whereas women might experience more subtle symptoms like insomnia, fatigue, headaches, or mood changes, leading to underdiagnosis. This atypical presentation can delay proper diagnosis and treatment.
• Restless Legs Syndrome (RLS): This neurological disorder, characterised by an irresistible urge to move the legs, often accompanied by uncomfortable sensations, is considerably more common in women than in men. RLS symptoms typically worsen in the evening or at night, making it difficult to fall asleep and stay asleep.
• Insomnia: Women are twice as likely to experience insomnia compared to men. This difficulty in falling or staying asleep can be chronic and significantly impact daily functioning. Various factors, including hormonal shifts, stress, and co-existing medical conditions, contribute to its higher prevalence in women.
• Caregiver Responsibilities and Multitasking: While societal roles are evolving, women often shoulder a disproportionate share of caregiving responsibilities, whether for children or elderly parents. Juggling these duties with work and other commitments can significantly reduce the amount and quality of sleep women are able to get, leading to chronic sleep deprivation. This “mental load” can make it challenging to switch off and relax, further impacting sleep.

Optimising Sleep Health for Women

Understanding the unique challenges women face in achieving restorative sleep is the first step towards better sleep health. Implementing good sleep hygiene practices is universally beneficial, but women may find particular benefit in tailoring these strategies to their specific needs and life stages:

• Prioritise Consistency: Maintaining a regular sleep schedule, even on weekends, helps regulate the body’s natural circadian rhythm.
• Create a Conducive Sleep Environment: Ensure your bedroom is dark, quiet, and cool (around 18°C is often recommended). Investing in good quality bedding and a comfortable mattress can also make a significant difference.
• Mind Hormonal Fluctuations: For menstrual cycle-related sleep issues, consider tracking your cycle to anticipate difficult nights and adjust your routine accordingly. During perimenopause and menopause, managing symptoms like hot flashes through lifestyle changes, or discussing hormone replacement therapy (HRT) with a healthcare professional, can significantly improve sleep.
• Manage Stress: Incorporate relaxation techniques into your daily routine, such as meditation, yoga, or deep breathing exercises, to calm the mind before bed. Journaling your worries before sleep can also be beneficial.
• Address Underlying Conditions: If you suspect a sleep disorder like sleep apnoea or RLS, or if you’re experiencing persistent insomnia, consult a doctor. Early diagnosis and appropriate treatment can make a profound difference. The National Sleep Helpline in the UK offers support and guidance.
• Limit Stimulants and Heavy Meals: Avoid caffeine and alcohol, especially in the late afternoon and evening. Eating large or spicy meals close to bedtime can also disrupt sleep.

In conclusion, the seemingly simple question of “Why do women sleep worse than men?” unravels a complex tapestry of biological, physiological, and societal factors. By acknowledging and addressing these unique challenges, women can take proactive steps towards reclaiming the restorative sleep they need for optimal health and well-being.
