We are facing a nationwide crisis of exhaustion. Regardless of your background—be it education level, income, ethnicity, or location—it’s likely that you’ve encountered serious sleep deprivation at some point in your life. In college, it was almost a rite of passage to survive on just a few hours of sleep, thinking you could easily catch up later. In the early years of your career, without the responsibilities of children, you may have thrived on 5-6 hours of sleep per night for extended periods. Youth, ambitious career aspirations, and a child-free household allowed for this kind of sleep deprivation, with weekends spent recuperating.
Then parenthood hits, and suddenly, the concept of a full night’s sleep becomes a distant memory. Experts may suggest that newborn sleep patterns are erratic and that this phase will pass within months. However, many parents quickly learn that the struggle for adequate rest can extend far beyond the infant stage. I have yet to meet a mother—of preschoolers, school-aged children, tweens, or teens—who can confidently claim to be getting the recommended 7-9 hours of sleep each night.
The truth is, no one seems to be sleeping well. Whether it’s responding to a fussy baby or waiting up for a teenager to return home, the reality is that many are awake at night and completely drained the following day. Women, in particular, have become adept at functioning on little sleep, redefining what constitutes a “good night’s sleep.” Remember when eight hours felt like a luxury? Now, if you manage to get six uninterrupted hours, you might feel like you’ve won the sleep lottery.
Despite any fleeting feelings of rejuvenation, your body is crying out for rest, and it’s vital to recognize that its physiological and mental health functions are at stake. The crisis of sleep deprivation in our country poses serious health risks. The more research we conduct, the clearer it becomes that inadequate sleep can have damaging consequences.
So, what exactly does sleep deprivation do to your body? Here are some alarming effects:
- Increased Health Risks: Chronic sleep loss heightens your susceptibility to numerous health issues, including a 36% rise in colorectal cancer risk, a 48% increase in the likelihood of developing heart disease, tripling the chances of Type 2 diabetes, and a 50% greater risk of obesity. There is also a 33% increase in dementia risk, not to mention the impact on your immune system, making you more vulnerable to common illnesses. If you’re frequently unwell, it might be a sign that you’re not getting enough sleep.
- Mood Disorders: Insufficient sleep can lead to significant mood disturbances. This extends beyond mere fatigue or forgetfulness; chronic lack of sleep is strongly linked to long-term mental health issues. Individuals suffering from anxiety or depression often sleep less than six hours a night, while insomnia is closely associated with heightened levels of depression—those lacking adequate sleep are five times more likely to experience it. Additionally, insufficient sleep can lead to increased hostility and negative emotions. Recent studies indicate women may experience greater memory loss and reduced work performance due to sleep deprivation compared to men.
- Premature Aging: Inadequate sleep triggers the release of cortisol, a stress hormone that accelerates the breakdown of collagen in your skin, leading to premature aging. Research by Estee Lauder found that poor sleepers exhibit more signs of skin aging and experience slower recovery from environmental stressors, such as UV exposure.
- Traffic Hazards: Perhaps the most concerning statistic relates to sleep and driving safety. According to a study by the AAA Foundation for Traffic Safety, drivers who get only five to six hours of sleep are twice as likely to be involved in a crash compared to those who manage seven hours or more. The crash risk increases significantly with less sleep; those who sleep just four to five hours have crash rates four times higher—similar to those of impaired drivers.
If these points don’t prompt you to reconsider your sleep habits, it’s hard to imagine what would. Consult with your healthcare provider about strategies to improve your sleep before you face chronic health issues or premature aging.
