Nodding Off by Day, Wide Awake at Night? How to Escape Spring Insomnia

The great novelist Charles Dickens once described a day in March in his novel Great Expectations like this:
“The sun was hot, and the wind was cold: it was summer in the light, and winter in the shade.”

This season—where the vitality of renewal coexists with the lingering traces of winter—creates a curious imbalance not only in nature, but also in our bodies. During the day, warm sunlight invites overwhelming drowsiness, yet when night falls, it can feel as though we are standing alone in a cold shadow, suddenly alert and wide awake. This is what might be called the “spring paradox.”

This phenomenon is not a sign of personal sensitivity or weak willpower. Rather, it is an honest physiological response as the body tries to adapt to the changing pace of the season. Difficulty falling asleep at night and struggling to wake up in the morning resemble the growing pains of a biological clock being recalibrated for a new environment. Spring insomnia in March is not a condition that needs to be “fixed” so much as a signal that our bodies are adjusting to the rhythms of nature.

Seasonal Jet Lag Inside the Body

Inside each of us operates a finely tuned internal clock known as the circadian rhythm, which governs sleep and wakefulness. During winter, this clock aligns with shorter days. When March arrives and daylight hours increase rapidly, the system can temporarily fall into confusion. Without boarding a plane, our bodies experience a kind of seasonal jet lag caused solely by changing light.

In particular, the rhythm of melatonin, the hormone that induces sleep, struggles to immediately adjust to longer days. While the world moves forward at spring’s brisk pace, the body still remembers winter’s long nights. The resulting imbalance manifests as fatigue and insomnia. This tiredness should not be interpreted as laziness, but as evidence that the body is actively adapting.

Morning Sunlight: The Most Reliable Sleep Timer

Sunlight is more than brightness—it is a sophisticated regulator that switches our brain’s sleep system on and off. Bright morning light, especially before 10 a.m., sends a strong signal to the brain’s master clock that the day has begun. This cue acts as a natural timer, scheduling melatonin release roughly 15 hours later and determining how deeply we sleep at night.

In practice, this means opening the curtains fully as soon as you wake up and looking outside for about ten minutes. Sitting by a window during a commute or bus ride and letting daylight reach your eyes is often enough. Rather than chasing sunlight all day, it is more effective to actively absorb morning light and, after sunset, dim indoor lighting to let the brain recognize that night has arrived.

Strategic Rest That Protects Night Sleep: The Power Nap

Enduring daytime sleepiness at all costs is not always wise. When severe afternoon fatigue is ignored, the body may interpret it as a crisis and release cortisol, a stress hormone that forces artificial alertness. What helps in this situation is a power nap—a short rest of about 20 minutes that clears mental fatigue and restores alertness.

Such brief rest can happen almost anywhere, but long-distance travel environments are particularly suitable. Dozing lightly on a bus, accompanied by steady motion and gentle vibration, can significantly reduce daytime exhaustion. Waking before entering deep sleep allows recovery without disrupting nighttime sleep rhythms, restoring energy while preserving the natural cycle.

The Betrayal of an Afternoon Cup of Coffee

Many people reach for extra coffee in March to fight drowsiness. However, caffeine interferes with adenosine, the chemical that builds up during wakefulness and creates sleep pressure at night. Adenosine is what makes us feel naturally ready for sleep, but caffeine blocks its action, causing the brain to believe sleep is unnecessary even when the body is exhausted.

As a result, an afternoon coffee steals the very sleepiness you need later that night. When spring fatigue strikes, it is better to rest your eyes by gazing at a distant view outside a window. Relaxing the brain naturally—rather than forcing alertness—allows adenosine to accumulate properly, laying the groundwork for deep sleep.

The Harder You Try to Sleep, the Farther It Runs Away

Excessive fixation on sleep is one of the strongest forces that entrenches insomnia. Telling yourself, “I must sleep for several hours because tomorrow is important,” pushes the brain into a state of conditioned alertness. Sleep is not something to conquer with willpower; it arrives naturally when mental tension is released.

If you remain awake for more than 20 minutes after lying down, it is better to get out of bed and move to another space. Struggling in bed teaches the brain to associate the bed with frustration rather than rest. Instead, read quietly or do gentle stretching until drowsiness returns. This approach restores healthy sleep associations far more quickly.

Giving Your Body Time to Match Spring’s Pace

Spring insomnia and daytime drowsiness are careful warm-up exercises for a new beginning. Rather than forcing yourself to keep up with the season’s sudden acceleration, allow your body the time it needs to find its own rhythm. When you release the obsession with perfect sleep and move in harmony with your body’s natural flow, rest returns calmly.

Just as you might lean against a window and rest briefly during a journey, may your nights also become a little slower and more comfortable. Small adjustments made today can lead to a refreshingly clear morning tomorrow.
