Social media is abuzz with claims that women need one to two hours more sleep than men. But is this true? Sleep psychologist Amelia Scott from Macquarie University dives into the science, uncovering a complex mix of biology, psychology, and societal pressures that shape women’s sleep patterns.

Research using tools like wearable sleep trackers and polysomnography shows women sleep about 20 minutes longer than men on average. A global study of nearly 70,000 people found women aged 40–44 get 23–29 minutes more sleep, while another study noted women spend 23% of their night in deep sleep compared to men’s 14%. However, individual sleep needs vary widely, and claiming all women need extra hours oversimplifies the issue.

Despite sleeping longer, women report worse sleep quality and are 40% more likely to face insomnia. Hormonal fluctuations, like those during puberty, pregnancy, or perimenopause, play a big role. For instance, dropping oestrogen levels before periods or during perimenopause often trigger sleep disruptions, like waking at 3 a.m. Health issues such as iron deficiency and thyroid disorders, more common in women, also contribute to fatigue.

Psychologically, women are more prone to depression, anxiety, and rumination, all of which disrupt sleep. They’re also prescribed antidepressants more often, which can alter sleep patterns. Socially, women bear a heavier load of caregiving and emotional labor, with Australian women clocking nine extra hours of unpaid work weekly compared to men. This limits daytime rest, piling pressure on nighttime sleep to restore energy.

Fatigue in women often stems from more than just sleep. The “mental load” of juggling work, family, and other responsibilities—especially during reproductive years or perimenopause—leaves many feeling drained, even with adequate sleep. Research also overlooks gender-diverse populations, missing how identity and social context shape rest.

In short, women may need slightly more sleep than men—about 20 minutes on average—but the real issue is the lack of opportunities to recharge. More than extra sleep, women need support to navigate the unique challenges they face in feeling rested.
