Chapter 1: Understanding Sleep's Impact on Mental Health

Sleep is often overlooked, yet it plays a crucial role in our overall well-being. It may not be the ultimate solution for every problem, but the effects of sleep on our lives are profound.

Quote: "Sleep deprivation can often feel like the root of many issues."

There are moments when I suspect that a lack of sleep is at the heart of my challenges. While life is seldom that straightforward, one must wonder how much better we could function if we placed a greater emphasis on sleep. Personally, I have noticed significant improvements since I began ensuring I get at least seven hours of rest each night, although achieving this can sometimes be a struggle.

The link between sleep and mental health is a complex interplay. Poor mental health can disrupt sleep patterns, and conversely, inadequate sleep can lead to mental health issues. For individuals with psychiatric disorders, chronic sleep disturbances are prevalent, affecting approximately 50% to 80% of those diagnosed with conditions like anxiety, depression, bipolar disorder, and ADHD.

A 2019 Harvard Mental Health Letter states, "Neuroimaging and neurochemistry research indicates that restorative sleep is essential for fostering mental and emotional resilience."

Nevertheless, advocating for good sleep might seem overly simplistic, especially since not everyone has the luxury of a good night's rest. This discussion primarily addresses those of us who often sacrifice sleep for seemingly more pressing tasks. I recognize my good fortune in not having young children, which can make sleepless nights unavoidable.

Since I started prioritizing my sleep, my life has transformed dramatically. While I don’t sleep perfectly every night, I manage to rest adequately, understanding the significant influence that sleep has on my daily functioning. It's not just about productivity; my social interactions are noticeably affected. A lack of sleep leaves me more irritable and impatient, qualities that hinder my ability to be as compassionate as I strive to be.

What happens, though, when anxiety keeps you awake? When mental health struggles interfere with sleep? This creates a vicious cycle, as a meta-analysis of 21 studies indicates that individuals with insomnia have twice the risk of developing depression. Simultaneously, depression and anxiety can also contribute to insomnia.

For me, it boils down to prioritization. On days when I feel I can’t perform effectively, I take the opportunity to nap whenever possible. Although research suggests that napping late in the day may disrupt overall sleep patterns, I sometimes find it hard to resist the immediate comfort of sleep.

Establishing a consistent sleep schedule and routine is something I can improve upon. I often disregard the advice to limit screen time before bed, as I find it an ideal moment to indulge in my favorite shows.

During normal circumstances, I would likely avoid binge-watching before bedtime, but the pandemic has shifted my perspective. With a more flexible work schedule, I find myself sleeping more than usual, partly as a means to maintain my mental health.

According to Kendra Cherry from Verywell Mind, “The mood fluctuations associated with poor sleep make it considerably harder to handle even minor daily stressors.” The little annoyances that typically wouldn't bother me become overwhelming without adequate rest. For instance, I find myself easily frustrated by traffic on days when I’ve had insufficient sleep, while on well-rested days, the commute feels manageable.

Naturally, fixating on sleep can be counterproductive. Like many, I struggle to fall asleep when I feel pressured to do so, often tossing and turning throughout the night.

The relationship between sleep and mental health is still a developing area of research, but it's evident that we must stop resisting our need for restorative sleep.

In the words of Johnny Jung in The Startup, "A sleeping brain is still active, sending electrochemical signals, particularly during REM sleep while we dream." Jung also notes that the glymphatic system, which serves as the brain's waste clearance mechanism, operates only during sleep. Discovered just seven years ago by researchers at the University of Rochester, this system removes neurotoxic waste, such as amyloid-beta, which is linked to Alzheimer's Disease.

Inadequate sleep impairs glymphatic function, leading to increased neurotoxic accumulation and compromised cerebrospinal fluid flow. Thus, sleep is a biological necessity, not a mere luxury.

However, only about 10% of Americans prioritize sleep over other daily pursuits like work, fitness, and social activities. I find myself among the majority who do not prioritize sleep, often drawn to the allure of entertainment over rest. It’s more enticing to binge-watch acclaimed series like "The Sopranos" or "The Wire" than to adhere to a strict bedtime.

Sleep lacks the glamour of more stimulating activities; it's just a basic requirement for functioning. In our instant gratification-driven society, sleep doesn’t offer the immediate rewards that watching TV, texting friends, or listening to music does.

Certainly, some circumstances make adequate sleep challenging. Many of us are young parents with restless children, military personnel, or individuals working night shifts or juggling multiple jobs.

When I experience a poor night’s sleep, I know that I need to compensate for it. Whether through a lunchtime nap, a brief rest during my planning period at work, or another opportunity to close my eyes, these moments of rest are essential.

While this may sound like a simplistic fix, and being well-rested doesn’t solve all of life’s problems, one undeniable truth remains: the best thing you can do for your mental health is to prioritize sleep. Your body and mind will thank you.
