Obstructive sleep apnea, a condition once thought to affect mainly men, is increasingly recognized as a health issue that presents differently in women.
How the condition shows up in women
Women with the disorder often lack the loud snoring traditionally linked to sleep apnea. Instead, they may experience frequent awakenings, nightmares, and insomnia, which can lead to daytime fatigue, morning headaches, and mood changes.
According to a sleep medicine physician at the University of Michigan, women tend to have more hypopneas—shallow breaths that reduce oxygen flow—while men experience more full pauses in breathing. Biological factors contribute to these differences. Women generally have smaller, more stable upper airways and less neck fat, reducing the likelihood of airway collapse that creates snoring. Hormones such as estrogen and progesterone also appear to support breathing during sleep, offering protection before menopause. After menopause, the decline in these hormones coincides with a sharp rise in both the prevalence and severity of obstructive sleep apnea among women.
Why women are often missed
Diagnostic criteria for the disorder were developed largely from studies of men, which means that women’s subtler breathing disruptions can be overlooked.
Potential health impacts
Untreated obstructive sleep apnea can strain the cardiovascular system. Each breathing pause prompts a surge of adrenaline, which over time may raise the chances of high blood pressure, heart attacks, strokes, irregular heartbeats, and heart failure. Some evidence suggests that women with severe sleep apnea face a higher likelihood of such complications than men.

Beyond heart risks, the condition can impair memory, cognition, and daytime alertness, raising the potential for accidents at work or on the road. It also intersects with mental health; managing sleep apnea may help alleviate anxiety and depression, according to sleep experts.
Getting a proper diagnosis
Women who suspect they have sleep apnea should monitor daytime energy levels and consider keeping a sleep diary to track nighttime awakenings and morning symptoms. Even if snoring is absent, it can still occur, and acknowledging it to a physician is important.
Addressing co‑existing conditions like hypertension or insomnia can improve sleep quality and may make underlying apnea more apparent. Advocating for a referral to a sleep medicine specialist is advisable, especially when standard tests have not yielded a clear answer.
While research continues to clarify the exact mechanisms behind sex‑specific symptoms, the current evidence highlights the need for heightened awareness and tailored diagnostic approaches for women.
Awareness saves lives.
