Why Do People Think Men Don't Need Sleep? Study Confirms A Harmful Stereotype

"I'll sleep when I'm dead" has been a rallying cry amid American hustle culture. Sacrificing sleep to work all hours of the day and put in 60- to 80-hour weeks still gets praised as a badge of honor, and it's not uncommon to hear people essentially boasting about how little sleep they get.

The researchers conducted a series of experiments on hundreds of people to understand the link between sleep and perceived masculinity. In one survey of 144 people, people saw men who say they don't get a lot of sleep as being significantly more masculine than men who say they sleep a lot. In another survey of 385 people, participants tended to describe very "manly" men as getting less sleep than "unmanly men," who generally got more sleep.

In other words, the assumptions went both ways: Men who don't get sleep were viewed as more masculine—and more masculine men were assumed to get less sleep.

Their other experiments showed people not only saw a lack of sleep as being a "manly" characteristic, but they also viewed men who lacked sleep as being more "agentic," i.e., more assertive, more focused on their personal goals, and more able to attain them. People also generally judged men who get enough sleep more negatively than men who sleep little, with men who slept a lot being viewed as "unmanly."

Viewing sleep as unmanly actually aligns with a larger phenomenon in which men tend to avoid engaging with their own health, according to the study's researchers Nathan Warren, M.S., M.A., and Troy Campbell, Ph.D. That's because masculinity is traditionally associated with strength, stoicism, and the avoidance of anything associated with femininity—such as caretaking and health.

"Men often choose to 'tough it out' by avoiding feminine associations with health care," Warren and Campbell write. "Despite the severe consequences for men's health, demonstrating stoic toughness allows men to display stereotypically masculine and agentic traits of strength, independence, autonomy, and resilience."

In other words, unhealthy behaviors have become associated with masculinity. They point to previous research by Will Courtenay, Ph.D., who notes how a man may brag that "I haven't been to a doctor in years" as a way to show how tough and masculine they are.

This research demonstrates just how dangerous gender stereotypes can be. Lack of sleep is associated with all sorts of health issues including weakened immunity and increased risks of heart disease, diabetes, obesity, and much more. Research has also found that men who sleep less tend to be more aggressive and violent, the researchers note.

Men shouldn't need to punish themselves to prove that they're men, and there is nothing commendable about working yourself until your body crumbles. (By the way, this is also not even an effective way to be productive—we know that taking regular breaks and nourishing ourselves is key to avoiding the devastating burnout that's also rampant amid hustle culture.)

The good news? Gender stereotypes are rapidly fading as people collectively move toward more expansive definitions of gender. Warren and Campbell note, "As society continues to challenge traditional definitions of masculinity, attitudes toward sleep may become more positive, and all people might enjoy more nights full of healthy sleep."
