Sleep deprivation is a condition characterised by inadequate or insufficient sleep sustained over a period of time. It can have a negative impact on brain, metabolic, and immune health. Research has suggested that men are more sleep-deprived compared to women, with a 2012 survey finding that nearly a third of men achieved less than 6 hours of sleep on average each night. However, this does not necessarily mean that men tolerate sleep deprivation better. In fact, one study found that men functioning on less sleep were likelier to misread a woman's interest in them, with their sleep-deprived brain likened to one impaired by alcohol. Another study found that sleep-deprived men made riskier decisions compared to women, who became more risk-averse. These findings suggest that the effects of sleep deprivation on decision-making performance may be different in women and men due to variations in brain activity.

What You'll Learn
Sleep deprivation is glorified in men, but it's unhealthy
Sleep deprivation is a serious issue that can have detrimental effects on one's health, and it is a problem that is particularly prevalent among men. Despite this, there is a dangerous cultural tendency to glorify sleep deprivation in men, associating it with masculinity and strength. This notion of "sleep machismo" risks the health and safety of those who buy into it.
Research has shown that men are more sleep-deprived compared to women, with a 2012 survey finding that nearly a third of men (29.2%) get less than six hours of sleep on average each night, despite the recommended minimum of seven hours for adults. This trend of men getting less sleep is linked to societal expectations of masculinity, with men who sleep less being perceived as more masculine and judged more positively.
However, this glorification of sleep deprivation among men is extremely unhealthy. Sleep deprivation can have a range of negative consequences for both physical and mental health. Physically, it can lead to a higher risk of cardiometabolic conditions such as obesity, high cholesterol, diabetes, and hypertension. It can also impact the immune system, increasing susceptibility to infections and reducing the effectiveness of vaccinations.
Mentally, sleep deprivation is closely connected to emotional regulation and mental health. It can contribute to the initiation and worsening of mental health problems, such as depression and anxiety. Additionally, it can impair cognitive functions, with studies showing that sleep-deprived men make riskier decisions and are more likely to misread social cues, such as a woman's interest in them.
The culture of "sleep machismo" is detrimental to men's health, and it is important to recognize that adequate sleep is essential for everyone, regardless of gender. Prioritizing sleep and seeking help for sleep deprivation are crucial steps towards maintaining overall health and well-being.

Men are more sleep-deprived than women
Sleep deprivation is a condition characterised by inadequate or insufficient sleep sustained over a period of time. It can have a negative impact on brain, metabolic, and immune health. It can also affect emotional regulation and increase the risk of cardiometabolic conditions such as obesity, high cholesterol, diabetes, and hypertension. Sleep deprivation is also associated with an increased risk of accidents and can take a toll on relationships.
Research has suggested that men experience sleep deprivation more frequently than women. A 2012 survey found that nearly a third (29.2%) of men achieved less than six hours of sleep on average each night, despite the recommended seven or more hours of sleep for adults. This phenomenon has been termed ""sleep machismo," which refers to the glorification of sleep deprivation and is associated with traditional masculine ideals.
Biological sex and gender norms influence sleep patterns, sleep problems, and sleep habits. Males are more likely to be "night owls," preferring to stay up late compared to females. Additionally, females are more sensitive to the effects of sleep deprivation due to differences in circadian rhythms. Shift work or irregular sleep schedules can disrupt their natural circadian rhythms, making them more susceptible to the negative consequences of sleep deprivation.
Hormonal changes also play a role in sleep differences between men and women. Women experience hormonal shifts during menstruation, pregnancy, breastfeeding, perimenopause, and menopause, which can contribute to sleep disturbances. For example, menopause is often associated with hot flashes, night sweats, and hormone level changes that can disrupt sleep. Additionally, sleep issues in women can impact fertility and pregnancy outcomes, with sleep-deprived women experiencing lower success rates with fertility treatments and higher risks of pregnancy complications.
While men may experience higher rates of sleep deprivation, it is important to note that both genders can suffer from the negative consequences of insufficient sleep. The effects of sleep deprivation on decision-making and cognitive functions differ between men and women, with sleep-deprived women exhibiting more selfish behaviour and men making riskier decisions.

Sleep loss impacts men and women's brains differently
Sleep deprivation is a condition characterised by inadequate or insufficient sleep sustained over a period of time. It occurs when an individual consistently fails to obtain the amount of sleep they need. Sleep deprivation can lead to poor short-term and long-term health outcomes and impair everyday functioning. Research has suggested that men are more sleep-deprived compared to women. A 2012 survey found that nearly a third (29.2%) of men achieved less than six hours of sleep on average each night. However, it is essential to note that the AASM recommends that adults get seven or more hours of sleep per night regularly.
The effects of sleep deprivation on decision-making performance may be different in women and men due to variations in brain activity. Optimal frontal lobe functionality is dependent on sleep, and sleep deprivation has a more notable impact on the female frontal lobe. After sleep loss, men make riskier decisions compared to when they are well-rested, whereas women show decreased risk aversion. Additionally, women exhibit increased selfishness and decreased inequity aversion after sleep deprivation. These differences may be related to intrinsic psychological gender differences in decision-making processes and the neurofunctional substrate involved.
Furthermore, sleep deprivation can have specific consequences for men's health. Men who work shifts without napping during the day are more likely to be diagnosed with cancer and have an increased risk of mortality from cancer. Sleep deprivation can also negatively impact testosterone levels, leading to difficulties in maintaining a healthy weight and potentially contributing to metabolic risk factors for diabetes and sleep disorders. Prolonged sleep deprivation can compound conditions like depression and anxiety, which are often overlooked in men due to societal expectations and outdated stereotypes.
While the cultural perception of "sleep machismo" glorifies sleep deprivation as a sign of masculinity, it poses significant health risks. Sleep deprivation can impair cognitive and emotional functions, with potential consequences for social interactions and overall well-being. Prioritising healthy sleep habits is crucial for both men and women to mitigate the negative impacts of sleep loss on brain function and overall health.

Sleep-deprived men are likelier to misread a woman's interest
Sleep deprivation is a condition characterised by inadequate or insufficient sleep sustained over a period of time. Research has suggested that men are more sleep-deprived compared to women. A 2012 survey found that nearly a third (29.2%) of men achieved less than six hours of sleep on average each night.
A study led by Dr. Jennifer Peszka found that a single night of missed sleep can impair a man's ability to discern how interested a woman is in having sex. The study involved 60 college-aged students who completed a survey about their sexual interest, sexual intent, commitment interest, and commitment aversion. The same group repeated the survey the following day after being deprived of one night's sleep. Researchers discovered that well-rested men and women rated the sexual intent of women as significantly lower than that of men. However, following a night of no sleep, men's perceptions changed, and they rated women's sexual intent and interest as higher.
The authors of the study attributed these findings to frontal lobe impairment caused by sleep deprivation, which impacts decision-making, moral reasoning, and risk-taking. Co-author Jennifer Penner, Ph.D., pointed out that this was the first study to explore the role of sleep deprivation in sexual decision-making. She highlighted that poor decision-making in these areas can lead to problems such as sexual harassment, unplanned pregnancy, sexually transmitted diseases, and relationship conflicts.
The findings suggest that sleep-deprived men are likelier to misread a woman's interest and make riskier decisions. This could be due to the impact of sleep deprivation on the frontal lobe, which may be more pronounced in females, leading to more selfish choices. These results indicate that sleep deprivation alters economic behavior in a gender-sensitive manner, with females exhibiting reduced risky choices and increased egoism compared to males.
It is important to note that the glorification of sleep deprivation, often associated with masculinity, is unhealthy and dangerous. Getting enough quality sleep is crucial for physical, mental, emotional, and social well-being.

Men doing shift work without napping are more prone to cancer
While there is some evidence to suggest that men are more sleep-deprived compared to women, with a 2012 survey finding that nearly a third of men (29.2%) slept less than six hours on average each night, it is a myth that men can tolerate sleep deprivation better. In fact, research has shown that men who sleep less are perceived as more masculine and are judged more positively by society. This perception has been termed "sleep machismo" by leading chronobiologist Dr. Charles Czeisler, who warns that this culture of glorifying sleeplessness is dangerous to health and safety.
Sleep deprivation has been linked to a host of health issues, including increased risk of cardiometabolic conditions such as obesity, high cholesterol, diabetes, and hypertension. It can also negatively impact brain, metabolic, and immune health, as well as impair everyday functioning. Furthermore, it can alter economic decision-making in a gender-sensitive way, with sleep-deprived men making riskier decisions compared to women, who become more risk-averse.
Shift work, which involves working outside the traditional nine-to-five day, is a common cause of sleep deprivation as it disrupts our natural circadian rhythms. This disruption can have negative health consequences, and in 2007, the International Agency for Research on Cancer (IARC) classified shift work with an irregular time pattern as a probable cause of cancer.
Several studies have found a link between night shift work and an increased risk of certain cancers, particularly breast and prostate cancer. This risk was observed specifically among men in a meta-analysis of 57 studies with over 8 million participants. However, other studies have failed to find a significant association between shift work and cancer risk, suggesting that shift work may contribute to cancer risk through other factors such as weight gain, lack of physical activity, and other health behaviours.
Therefore, while there is some evidence to suggest a link between shift work and cancer risk, particularly for men, the exact relationship is still not fully understood. To reduce their cancer risk, shift workers, especially men, should prioritise their general health by maintaining a healthy diet and lifestyle, as well as seeking support to improve their sleep quality and duration.
