When the Ink Smears

Sleep?

What does ink symbolize? Ink preserves. Ink records. Ink testifies. Ink endures. It marks identity. It writes stories. But it also stains.

Sleep is the difference between a life written clearly versus one smudged by neglect. When we deprive ourselves of sleep, we blur the testimony our lives are meant to write. Fatigue distorts our judgment, productivity, and moral clarity. Our minds and bodies need sleep to function. Just as ink needs proper care to remain legible, so too do we.

So what is sleep?

Sleep is the body’s natural reset. It is more than simply closing our eyes and waiting for the next day; it restores energy and function. Sleep is when muscles repair, hormones reset and the brain clears metabolic waste.

However, we have largely neglected this essential reality. As busy students at a tech school, our days are filled with homework, studying, classes, and friends. In the pressure to keep up with everything, sleep is often the first thing we sacrifice. The neglect of rest has become so normalized that it is almost worn as a badge of honor: “I only slept four hours last night,” or “I pulled an all-nighter.” What should be recognized as exhaustion is instead praised as dedication.

But we are not all powerful beings capable of functioning without sleep. God designed our bodies with limitations, and when we push beyond our limits, there are consequences. Yet the consequences are so grossly underestimated. Sleep is not some quality we can sweep under a rug and return to later. One hour of lost sleep can take as long as up to four days to fully recover ¹. When we deprive ourselves of sleep, we can never fully recover the sleep we have lost.Students who work themselves on deprived sleep and try to “catch up” later should take note: studies have shown that after 10 days of chronic partial sleep restriction followed by a week of unrestricted sleep, most measures of brain function including cognitive accuracy, motor activity, and brainwave patterns do not return to baseline levels even after seven days of recovery ². In other words, the effects of sleep loss reach far beyond simple fatigue, they shape the very days we live, long after the days of lost sleep have passed. And when that happens, we cannot live up to the full potential God has planned for us.

Why did God create sleep?

All of God’s creatures sleep. Humans, mammals, fish, worms, even certain single-celled micro-organisms sleep.

From the beginning, God demonstrated the power of rest: He placed Adam into a deep sleep (Genesis 2:21) to enable the creation of Eve. While this was a supernatural act, it reflects God’s design of rest and reliance on Him. It shows that there is a time to yield, a time to stop, and a time to trust God with what we cannot control.

Sleep was given to us as a form of deep rest, a gift woven into the very fabric of our creation. Just as God rested on the seventh day, setting apart the Sabbath as holy and calling His people to enter into that rest (Exodus 31:16; Leviticus 23:3), we too called to honor the rhythm of rest in our own lives. When we sleep, we relinquish control and pause our production. We acknowledge our finitude, trusting God to wake us up the next day.

This physical pause mirrors the spiritual rest Hebrews 4:11 speaks of: urging us to ‘strive’ to enter it, which requires both faithfulness and intention. By completing the work God has entrusted to us and submitting to the limits He has designed, we participate in a pattern of rest that preserves our bodies, renews our minds, and strengthens our capacity to serve and glorify Him.

Sleep also reminds us of our human finitude. Our physical bodies need food, water, oxygen, and sleep in order to function. This dependence on God for our existence shapes how we think, learn, and perform each day (Matthew 6:26). The effects are especially clear in our academic lives, where the quality of our focus and performance reflects whether we honor these essential needs.

How does sleep affect our academics? Our memories? Our career?

Extensive research has highlighted the importance of sleep. In one study, first-year college students from three universities wore sleep actigraphy for a month early in the academic term, across five independent samples. The results showed that each hour of lost average nightly sleep corresponded to a 0.07 drop in end-of-term GPA ³. Even modest reductions in sleep produced measurable effects on academic performance, highlighting its role as a crucial and active component of learning and memory retention.

This connection becomes clearer when we consider sleep’s role in learning and memory. The brain requires rest to absorb new information effectively. In one study, healthy young adults were divided into two groups: one was allowed a 90-minute nap, while the other remained awake. Both groups completed intensive learning tasks before and after the nap period. Those who stayed awake showed a progressive decline in learning ability, even though their concentration remained stable. Compared to the napping group, their performance was 21% lower, demonstrating a clear advantage for rest ⁴. Without adequate rest, the hippocampus becomes saturated, limiting the brain’s capacity to encode and retain information. God’s design is evident in this process: sleep restores our minds and consolidates memory, enabling us to learn, remember, and act with clarity each day.

Similarly, sleep is essential afterward for retaining information we have learned. Studies of memory consolidation show that participants who rested after learning demonstrated significantly better recall than those who remained awake during the same interval ⁵. Pulling all-nighters or relying solely on caffeine may give the illusion of productivity, but the brain has a finite capacity; without rest, our ability to encode and retain knowledge diminishes. These boundaries are not flaws in our design but reflect the way we were created to live.

This design carries a deeper lesson: just as our brains require time to consolidate learning, our lives require periods of pause to integrate experience and prepare for what comes next. Growth and flourishing are not achieved by constant effort alone; they emerge in the rhythm of work and rest. When God instituted the Sabbath, He emphasized rest as part of life’s proper order, and sleep functions in the same way. In the time we step away from our work, sleep restores our minds and refreshes our bodies. Like ink drying on a page, the lessons of the day are quietly preserved.

Just as sleep consolidates the work of the day for the mind, Scripture reminds us that flourishing or faltering depends on how faithfully we steward what we’ve been given.

“For whoever has will be given more, and they will have an abundance. Whoever does not have, even what they will have will be taken from them.“

Matthew 25:29

The idea is simple: if we faithfully manage our time, finish our work, and dedicate our time to completing entrusted tasks, we will have ample time to enjoy sleep at night (Hebrews 4:11). Sleep will then help us solidify information we learned throughout the day, clearing our hippocampus of extraneous memories, and shift important ones into our long-term memory. After a night of restorative sleep, we wake up refreshed, ready to face the labors of the day (Isaiah 50:4, Psalms 5:3).

However, if we spend our day idling and squandering the time we were given, we live out the warning of the parable of the talents. After wasting the day, we panic at night, rushing to finish work that should have been done earlier. This cuts into the time meant for sleep, leaving us groggy and mentally unprepared for the next day. Learning, focus, and efficiency all suffer. As our productivity declines, we are forced to stay up even later to catch up on missed work. Ultimately, the rest we cling to dwindle as this downward spiral continues, and each misused hour magnifies the toll on body, mind, and spirit. When burnout sets in, the consequences go beyond mental fatigue: our bodies begin to suffer, leaving us vulnerable to illness and long-term health risks.

How does sleep impact our health? Our immune system?

The Guinness World Record no longer recognizes sleep deprivation as one of its achievements. Sleep deprivation is so prevalent and detrimental to our health that it increases global risk of mortality by 13%, costing the US around 1.2 million working days every year ⁶. A 14-year study of 2,282 male workers in Japan found that sleeping less than six hours per night was associated with a more than threefold increased risk of cardiovascular or coronary events ⁷.

Beyond its impact on longevity, sleep deprivation also compromises the body’s ability to fight illness. In a controlled study of approximately 160 healthy adults, researchers measured sleep duration for one week using wrist monitors before exposing participants to a rhinovirus. Participants were grouped by sleep duration: less than 5 hours, 5–6 hours, 6–7 hours, and more than 7 hours per night. After viral exposure, those who slept less than 5 hours were 4.5 times more likely to develop a clinically verified cold, while those who slept 5–6 hours were 4.2 times more likely compared to individuals who slept more than 7 hours. These results remained significant even after adjusting for factors such as age, stress levels, and baseline immunity ⁸.

When we cut corners on rest, the consequences extend far beyond simple tiredness. Sleep deprivation weakens the immune system, increases susceptibility to illness, and elevates the risk of accidents and long-term health problems. During exam seasons, when many of us sacrifice sleep to finish assignments or study longer, we often find ourselves becoming ill and exhausted, less able to complete the very work we stayed awake to accomplish. The hours we forgo are not easily recovered, and the toll on our bodies can last for days.

Since our bodies are gifts from God, neglecting sleep becomes a matter of stewardship. Scripture repeatedly emphasizes that the body is entrusted to us, not owned by us (1 Corinthians 6:19-20; 1 Corinthians 3:16-17; Romans 12:1). Chronic sleep deprivation treats this gift carelessly, prioritizing function over preservation. The consequences however, also extend beyond ourselves: fatigue can increase risks of accidents and diminish our ability to protect and care for others.

How does our lack of sleep affect others?

Fatigue is one of the leading causes of accidents worldwide. So serious is this risk that, on average, someone dies in a traffic accident due to a fatigue-related error every hour. These accidents typically occur in two ways. First, a driver may fully fall asleep for several seconds, losing complete control of the vehicle. More commonly, accidents occur due to microsleeps, which are brief, involuntary lapses in attention that last a fraction of a second to several seconds. During a microsleep, the brain essentially “switches off,” and the driver may continue steering or pressing the pedals, but their awareness and ability to react are severely impaired. To an outside observer, it may appear the driver is awake, yet in those critical moments, they are not processing their surroundings. At highway speeds, even a two-second lapse can cover more than half a football field, making microsleeps one of the deadliest consequences of sleep deprivation⁹.

Pulling an all-nighter increases attentional failures by over 400%, and sleeping only four hours per night for six consecutive nights produces impairment comparable to staying awake for 24 hours. In practical terms, a driver after a week of insufficient sleep may be just as impaired as someone who has not slept at all¹⁰. Both acute and chronic sleep loss, therefore, greatly increase the risk of microsleeps behind the wheel.

More subtly, there is a smaller, perhaps just as important consequence for us as Christians. When we are tired, we lose concentration and struggle to be fully present. Our patience shortens, our attention drifts, and we fail to give ourselves fully to others. Yet Scripture repeatedly calls us to love our neighbors and serve one another faithfully (1 Peter 4:10, Galatians 6:2). When others need our attention, help, or presence, fatigue dulls our awareness and drains our energy, leaving us unable to respond as we should. If this is what’s at stake, the question becomes practical: how do we align our lives to honor the gift of sleep?

So what can I do to get more sleep?

The answer begins with understanding why we struggle: our lives are full, our schedules demanding, and our temptation is to push past our limits. Recognizing these limits is the first step toward rest. God has built them into us, and we are called to order our lives around them rather than resist them. Learning to sleep well is an act of humility, an acknowledgement that we are not self-sustaining but fully dependent on Him.

When we live intentionally, serving God, caring for others, and completing the work entrusted to us, we create space for the rest our bodies require. While not everything is within our control, some habits are. Choosing to step away from distractions, quieting our minds, and preparing ourselves for rest are all ways of stewarding the life we have been given.

In these daily decisions, we align ourselves with the rhythm God designed: a rhythm of work and surrender, effort and rest. Sleep is not wasted time; it is a necessary pause where what we have lived is quietly preserved. Like ink drying on a page, sleep allows the lessons, choices, and moments of our lives to settle into clarity. Without it, everything blurs: our thoughts, our actions, and even our witness—all smudges. With it, what God is writing through us becomes more legible, more faithful, and more whole.

In the end, the question is not simply whether we are getting enough sleep, but whether we are living in a way that allows our lives to be written clearly, so that the story we leave behind reflects the One who is writing it.

Author’s Note: I want to extend special thanks to Matthew Walker. His bookWhy We Sleep and his TED Talk were a major inspiration for this piece, shaping both my understanding of sleep and my conviction to prioritize it. Sleep is not just a biological necessity. It is a gift, essential for our minds, bodies, and the way we live each day.
