Spring Forward 2026: What the Time Change Does to Your Body and How to Adjust
A familiar March ritual—with real effects
March arrives with a particular kind of momentum. In many parts of the United States, it is a month associated with rapid changes—shifts in temperature, the possibility of severe weather, and a general sense that winter is loosening its grip. It is also the month when many people “spring forward,” moving clocks ahead by an hour as daylight saving time begins.
That one-hour change can sound minor on paper. In practice, it often feels bigger. The transition can bring negative impacts and may take time to adjust to, particularly for anyone whose sleep is already stretched thin. For households with small children or pets, the disruption can be even more noticeable because their routines and sleep schedules tend to be consistent and, in many cases, non-negotiable.
The good news is that there are straightforward ways to prepare. None of these steps can guarantee a perfect, painless transition, but they can make the week of the time change easier to navigate—and they can help set expectations for yourself and those around you.
Why an hour can feel like more than an hour
When clocks spring forward, the timing of sunrise shifts suddenly. The day feels longer, and the morning light arrives later by the clock. This can be jarring to the body’s internal rhythm because our bodies are linked to experiencing light and dark consistently. A sudden change in when light appears—paired with the demands of work, school, and family schedules that don’t pause—can create a mismatch between how rested you feel and what the day requires.
In other words, daylight saving time is not only a technical adjustment. It is a shift in the cues your body uses to regulate sleep and wakefulness. That is why the transition can take time, and why a strategy built around sleep habits and light exposure can be useful.
Start preparing the week before the time change
If you know the time change is coming, the most helpful window for preparation is often the week leading up to it. The goal is not to overhaul your life. It is to reduce the number of factors that make sleep worse right when you need it most.
A simple starting point is to take care of yourself in the days before the clocks change. Try to get good nights of sleep leading up to the day itself. If you are tempted to push through late nights or pull an all-nighter, it is worth reconsidering: all-nighters before springing the clocks forward can make the days following the change feel especially tough.
Prioritize sleep in the week before. Aim for consistently good nights of sleep rather than trying to “catch up” at the last minute.
Avoid all-nighters. Going into the time change already sleep-deprived can make the adjustment feel sharper and more frustrating.
Use daylight and movement to support your routine
Light exposure and activity can play an important role in how quickly you adapt. In the lead-up to the time change, make efforts to be in the sun and be as active as possible. This is not about intense workouts or complicated plans; it can be as simple as spending time outside during the day and keeping your body moving.
Food choices can also support your overall energy and sleep quality. Try to eat healthy during the week of the transition. If you want a small motivator, one suggestion is to save desserts as a reward for making it through the time change—an approach that keeps the focus on steady habits first.
Get outside when you can. Daytime sunlight helps reinforce the body’s sense of day versus night.
Stay active. Movement during the day can support better rest at night.
Eat with sleep in mind. A healthy routine can make the transition feel less draining.
The day before: protect your sleep from common disruptors
The day before the clocks change is a good time to remove obvious obstacles to sleep. Two common disruptors are caffeine and alcohol, particularly when consumed excessively. Limiting them can help you get less-impaired sleep at the moment when you most need it.
Another factor is screen time. As bedtime approaches, try to limit time on the phone so you are not overstimulated before bed. It is a practical step that can be easy to overlook—especially when routines are busy—but it can make it easier to wind down.
Limit excessive caffeine and alcohol the day before. The goal is to make sleep as restorative as possible.
Reduce phone time near bedtime. Avoiding overstimulation can support an easier transition into sleep.
After the clocks change: consider an earlier wake-up
Many people are not naturally inclined to get up early. Still, waking up early after the clocks change can be a useful tool for adjustment. It may sound counterintuitive—especially if you already feel like you lost an hour—but it can help align your body with the new schedule.
One specific tactic is to seek out early morning light. If you wake up early after the time change and get at least 30 minutes of early morning sunshine on your face, it can help your body adapt to the shift in sunlight as quickly as possible. The idea is to use light as a signal to your body that the day has begun, which can help reduce how much your sleep is impacted that night.
Try waking up earlier after the change. Even if it feels difficult, it can support faster adaptation.
Get 30 minutes of morning sunshine. Early light exposure can help your body adjust to the new timing of daylight.
March’s daylight surge: why timing feels different
Daylight saving time does not happen in a vacuum. It arrives in a month when daylight is already increasing. March is often known for drastic shifts in temperatures and severe weather, but it is also an important month in terms of sunshine in general. The days are getting longer—something most people notice intuitively as the month progresses.
In fact, March is the month that has the greatest increase in sunlight in the United States. From March 1 to March 30, people in the northern portions of the country can see around 30 to 45 minutes more sunlight. In the South, the increase is more like 15 to 30 minutes.
This difference between regions is tied to latitude. Higher latitudes see more drastic changes in daylight due to the Earth’s tilt. A commonly cited example of how dramatic this can be is Alaska, where some parts experience constant darkness in winter. While most of the country does not experience extremes like that, the same underlying geometry explains why daylight changes can feel more pronounced the farther north you go.
How long until sunrise “looks normal” again?
One of the more surprising aspects of the spring transition is that it can take weeks for the mornings to feel familiar again. A useful reference point: it takes about four to five weeks for the clock to read the same at sunrise as it did before the time change.
That does not mean the body feels out of sync for a full month. But it does help explain why the shift can linger in subtle ways. If you find yourself thinking, “Why does morning still feel different?” several weeks later, the changing relationship between the clock and sunrise is part of the answer.
Households with kids and pets: plan for routine pressure
Daylight saving time can be challenging for anyone, but it is especially important to prepare if you have small children or pets. Their sleep schedules and routine expectations can create pressure points in the first days after the clock change. When they wake up, they wake up—regardless of what the clock says—and that can ripple through the household’s energy and mood.
For families, the most practical approach is to focus on the controllable basics: protect sleep in the week before, avoid overstimulating habits at night, and use morning light after the change to help everyone adjust. Even small improvements in the adults’ rest can make it easier to handle the inevitable bumps in routine.
A realistic expectation: helpful steps, not perfect outcomes
It is worth stating plainly: these steps will not guarantee that you—or the people and animals around you—won’t struggle when the clocks spring forward. Daylight saving time is a real disruption, and some people are more sensitive to schedule shifts than others.
Still, the same steps are unlikely to hurt. Better sleep before the change, fewer late-night stimulants, reduced phone use near bedtime, and intentional exposure to morning sunshine are practical measures that support adjustment in a way that fits most lifestyles.
The bottom line: make room for a slower week
The most useful mindset for the spring time change may be the simplest one: give yourself, and those around you, grace the week after daylight saving time. If focus feels harder, mornings feel rough, or routines feel slightly off, that experience is common. March already brings change in the atmosphere and in daylight. Adding an abrupt clock shift on top of it can take time to settle.
By preparing in the days leading up to the change—and by using light, sleep habits, and reasonable expectations afterward—you can make “spring forward” feel less like a shock and more like a manageable transition into brighter evenings ahead.
