Americans' Sleep Deprivation: Causes And Effects

Sleep deprivation is a pervasive issue in the United States, with a growing number of Americans reporting that they are not getting enough sleep. This trend is concerning, as sleep deprivation can have negative impacts on both physical and mental health, contributing to issues such as depression, heart disease, lowered immunity, obesity, and type 2 diabetes. While the reasons for sleep deprivation vary, factors such as stress, long work hours, and the use of electronic devices close to bedtime play a significant role. Additionally, cultural norms that prioritize industriousness and productivity may also contribute to Americans' sleeplessness. Addressing this issue is crucial, as adequate sleep is essential for maintaining optimal health and well-being.

Stress and long work hours

Research reveals that stress interferes with the sleep of many American adults and teens, causing them to sleep less than the recommended seven to nine hours nightly. Stress often keeps individuals awake at night, and when they do not get enough sleep, they tend to feel more stressed. Adults with higher stress levels are more likely to experience increased stress due to inadequate sleep. This phenomenon is even more pronounced in teens, with 39% of those with higher stress levels reporting heightened stress when they don't get enough sleep, compared to only 3% of their lower-stress peers.

Long work hours also play a significant role in sleep deprivation. Americans work an average of 9.5 hours a day and often spend extra hours working from home, resulting in reduced sleep time during workdays. This work schedule, coupled with stress, takes a toll on sleep quality and duration. The constant pressure to work more and the blurring of boundaries between work and home life lead to sacrificing personal needs, including sleep, to complete work tasks.

The impact of stress and long work hours on sleep has tangible consequences. Sleep-deprived individuals may experience various issues, such as difficulty concentrating, irritability, lack of motivation, and increased vulnerability to stress. Additionally, insufficient sleep can lead to serious physical ailments, including cardiovascular problems, high blood pressure, weight gain, and a weakened immune system.

To break the cycle of stress and sleep deprivation, it is crucial to prioritize sleep and implement stress management techniques. This may involve seeking professional support, improving sleep hygiene, and making lifestyle adjustments, such as reducing screen time before bed and optimizing the bedroom environment.

Blue light from electronic devices

The impact of blue light on sleep is significant. Research has found that exposure to blue light in the evening can reduce melatonin levels, disrupting the body's internal clock and negatively affecting sleep quality. To make matters worse, many Americans stay up late at night, entertaining themselves with these devices, further delaying their sleep and contributing to sleep deprivation.

To mitigate the negative effects of blue light, experts recommend reducing screen time, especially before bed. This can be achieved by turning off electronic devices and bright lights at least two hours before bedtime. Additionally, wearing glasses that block blue light can be helpful in reducing exposure.

The blue light emitted by electronic devices not only impacts sleep but also contributes to other health issues. Research has linked insufficient sleep to various health problems, including depression, heart disease, lowered immunity, obesity, and type 2 diabetes. Therefore, addressing blue light exposure is crucial not only for improving sleep but also for maintaining overall health and well-being.

While reducing screen time can be challenging in today's technology-driven world, it is essential to prioritize sleep to ensure we get the recommended seven to eight hours of sleep per night. By making small changes, such as setting a bedtime for device use or opting for alternative activities before bed, Americans can take steps towards improving their sleep habits and overall health.

Sleep isn't prioritised

A big reason why Americans don't get enough sleep is that they simply don't consider it a priority. Research from the National Sleep Foundation suggests that when asked which of five items were most important to them personally, only 10% of respondents said sleep—far fewer than those who cited fitness/nutrition, work, and hobbies. This is despite the fact that a good night's sleep is just as important for health as regular exercise and a healthy diet.

This lack of prioritisation of sleep is also reflected in American culture, with a longstanding emphasis on industriousness and productivity. The idea that hard work is morally correct and that success is evidence of divine favour can be traced back to the Protestant settlers who colonised the country. This has resulted in a pervasive belief that sleep is unnecessary and a waste of time that could be better used.

The COVID-19 pandemic may have also played a role in disrupting Americans' sleep patterns, with the phenomenon of "revenge bedtime procrastination" seeing people put off sleeping and instead scroll on social media or binge-watch TV as a way to handle stress.

Additionally, the modern habits of staying up late to use electronic devices and working longer hours with longer commutes leave less time for sleep. The blue light from electronic devices can interfere with the body's production of melatonin, the sleep hormone. Working longer hours can lead to a sleep-wake cycle disruption, especially for those working shift work.

Sleep disorders

The impact of sleep disorders on overall health cannot be overstated. Sleep deprivation contributes to various health issues, including depression, heart disease, lowered immunity, obesity, and type 2 diabetes. It can also increase the risk of developing chronic conditions such as heart attacks, stroke, and diabetes. Additionally, it can affect cognitive abilities, mood, heart health, and immune health.

To address sleep disorders, individuals may consider seeking professional help and making lifestyle changes. Consulting a healthcare professional is advisable, especially for those who have always had trouble sleeping. Proper "sleep hygiene" and lifestyle changes are often recommended. This may include reducing screen time at night, optimising the bedroom environment, and maintaining consistent sleep and wake-up times.

In some cases, a more intensive approach may be necessary, such as sleep testing to diagnose underlying conditions like obstructive sleep apnea (OSA). Sleep disorders can have a significant impact on overall health and well-being, and it is crucial to prioritise sleep and take the necessary steps to improve sleep quality.

Long commutes

This shift in work patterns can disrupt the body's natural sleep-wake cycle, especially for those working late nights or early mornings. The COVID-19 pandemic has also affected sleep patterns, with the concept of "revenge bedtime procrastination" emerging, where people delay sleep to scroll on social media or watch TV as a stress-coping mechanism.

The cultural emphasis on industriousness and productivity further exacerbates the issue. The belief that hard work leads to success is deeply rooted in American culture, making it challenging for individuals to prioritize sleep.

As a result, Americans are averaging 6.8 hours of sleep nightly, and the number of people getting six hours or less has increased from 11% in 1942 to 40% in 2013. This sleep shortfall is taking a toll on overall well-being, with more Americans reporting that they would feel better with more sleep.
