Women with polycystic ovary syndrome (PCOS) are more likely to experience sleep disturbances such as insomnia and sleep apnea. This is due to the hormonal imbalances associated with PCOS, which can disrupt the sleep-wake cycle.
PCOS is a common hormonal disorder affecting 5-13% of women of reproductive age. It is characterised by hormonal imbalances, irregular periods, and the presence of small cysts on the ovaries. While various factors contribute to the development and progression of PCOS, sleep is often overlooked as a crucial component in managing the condition.
Sleep plays a vital role in maintaining overall health and hormonal balance. During sleep, the body repairs, restores, and regulates various physiological processes, including hormone production. Poor sleep can disrupt the delicate hormonal balance in the body, exacerbating the hormonal imbalances already present in individuals with PCOS.
Sleep disturbances can impact the menstrual cycle, weight gain, and insulin resistance, all of which are common concerns for individuals with PCOS. Lack of sleep affects the regulation of appetite-controlling hormones, such as ghrelin and leptin, leading to increased feelings of hunger and cravings for high-calorie foods.
Additionally, PCOS is associated with increased levels of stress hormones such as cortisol, which can further disrupt sleep and contribute to a vicious cycle of sleep disturbances and hormonal imbalances.
Optimising sleep quality is an important aspect of PCOS management. This can include establishing a regular sleep schedule, creating a relaxing bedtime routine, limiting exposure to electronic devices, and managing stress and anxiety.

What You'll Learn
Sleep disturbances in women with PCOS
Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects the reproductive, metabolic, and psychological health of women. It is characterized by hormonal imbalances, irregular periods, and the presence of small cysts on the ovaries. PCOS can significantly impact a woman's physical and emotional well-being. Sleep disturbances are common in women with PCOS and can exacerbate the condition's symptoms.
Prevalence of Sleep Disturbances in PCOS
Sleep disturbances, including insomnia and obstructive sleep apnea (OSA), occur more frequently in women with PCOS compared to those without the syndrome. This is true even when accounting for body mass index (BMI); sleep problems also occur in women with PCOS of normal weight. The prevalence of OSA in women with PCOS ranges from 17-75%, much higher than in other women of similar age and BMI.
Pathophysiology of Sleep Disturbances in PCOS
The pathophysiology of PCOS involves hyperandrogenemia, a unique form of insulin resistance, and possible changes in cortisol and melatonin secretion, which may reflect altered hypothalamic-pituitary-adrenal (HPA) function. Obesity, which is common in PCOS, can further contribute to sleep disturbances, particularly OSA, due to anatomical changes in the upper airways and thoracic region.
Impact of Sleep Disturbances on PCOS
The specific impact of sleep disturbances on the health of women with PCOS is not yet clear. However, both PCOS and sleep disturbances are associated with long-term deterioration in cardiometabolic health and an increased risk of type 2 diabetes. Poor sleep quality is also associated with an increased risk of obesity and insulin resistance, which play a key role in PCOS.
Management of Sleep Disturbances in PCOS
The management of sleep disturbances in PCOS should be part of an interdisciplinary model of care. Referral to a sleep specialist is recommended for diagnosis and treatment of sleep disorders such as OSA and insomnia. Weight loss is often recommended for overweight and obese individuals with OSA, and oral appliances or continuous positive airway pressure (CPAP) therapy may be used to treat OSA. Cognitive behavior therapy (CBT) is recommended as the first-line treatment for insomnia. Sleep hygiene approaches, such as avoiding caffeine and regular physical activity, can also be beneficial for those with sleep disturbances.

Obstructive sleep apnea
OSA has been found to be more prevalent in women with PCOS, with one study reporting that the risk for OSA is at least 5-10 times higher in women with PCOS compared to those without. The increased prevalence of OSA in women with PCOS may be due to several factors, including obesity, insulin resistance, and hyperandrogenemia, which are all common features of PCOS.
The link between PCOS and OSA has important implications for the health and quality of life of women with PCOS. Untreated sleep apnea may worsen other PCOS symptoms and increase the risk of developing type 2 diabetes, obesity, and cardiovascular disease. Therefore, it is crucial to diagnose and treat OSA in patients with PCOS to improve their overall health and well-being.

Insomnia
Chronic sleep deprivation can lead to high levels of cortisol, which has been linked to increased inflammation and more severe PCOS symptoms.

Sleep and recovery
Sleep is critical for managing stress levels and vice versa. Keeping your stress under control is a key part of keeping PCOS symptoms and inflammation at bay. However, people with PCOS often experience hormone imbalances relating to cortisol and melatonin, which are responsible for the sleep-wake cycle.
Insomnia
Insomnia is defined as the inability to get enough sleep. People with insomnia may find it challenging to fall asleep or stay asleep. Insomnia can cause irritation, low energy levels, and mood changes. Insomnia can cause or be caused by insulin resistance, which is common in people with PCOS.
Obstructive sleep apnea
Obstructive sleep apnea (OSA) is defined as the stopping of breathing once or numerous times during sleep. People with PCOS are 30 times more likely than those without the condition to suffer from OSA. Sleep apnea may increase symptoms associated with PCOS such as fatigue, difficulty losing weight, hypertension, and insulin resistance.
The importance of sleep
Without sufficient sleep, you may feel tired, irritable, and slow. Lack of sleep goes deeper than that—especially if you have PCOS. Sleep is critical for helping your mind and body recover and recharge and has been linked to memory consolidation.
The relationship between sleep and recovery
Sleep can help the body to return to baseline, especially after exercise. Movement is helpful for people with PCOS in particular because it has been shown to improve insulin resistance and overall symptoms. If you are into endurance training, weightlifting, or other high-intensity exercise, sleep is crucial for recovery because aerobic fitness can put too much stress on your body and worsen symptoms if you overdo it.

Remedies for sleep disturbances associated with PCOS
- Establish a sleep routine: Limit screen time, wear blue light glasses, get morning sunlight, give yourself time to digest after dinner, be mindful of caffeine intake, and optimise your sleep environment.
- Consistency: Establish a regular sleep-wake schedule, even on weekends.
- Create a relaxing bedtime routine: Engage in relaxing activities such as reading, taking a warm bath, or practicing gentle stretching or yoga.
- Limit exposure to electronic devices: Implement strategies to minimise device usage before bed, such as using blue light filters or night mode settings.
- Manage stress and anxiety: Implement stress management techniques such as deep breathing exercises, meditation, or gentle yoga.
- Create a restful sleep environment: Ensure a comfortable temperature, typically between 60 and 67 degrees Fahrenheit (15-20 degrees Celsius). Use blackout curtains or an eye mask to block out excess light, and use earplugs or a white noise machine to minimise noise disruptions.
- Prioritise sleep: Implementing these changes may take time and patience. Be consistent in practicing good sleep hygiene and give your body time to adapt to the new sleep routine.
