Spring Reboot: Why Now Is the Best Time to Start New Habits

More light, longer days, better weather—in spring, so many things suddenly feel a little easier again. You have more energy and more motivation to tackle things. The idea of a fresh start comes almost automatically. But that’s exactly where the trap lies.

Many people use the change of seasons to try to change everything at once: getting up earlier, exercising more, eating better, scrolling less, starting a new hobby. And a few weeks later, there’s often not much left of it. Not because you lack discipline, but because your body isn’t designed for such radical changes.

Spring isn’t the time for a complete 180-degree transformation. It’s more of a window during which your body is more open to change—as long as you don’t overwhelm it. If you make the most of this moment, it’s not about “starting from scratch,” but about making small adjustments that improve your life in the long run.

In this article, we’ll take a closer look at what happens in your body, why habits often fail—and how to make changes that work in the long run.

Why Habits Are So Hard to Change

Habits aren’t random. They’re programs your brain has developed to conserve energy. Instead of making every decision consciously, many activities—like brushing your teeth, snacking while watching TV, or reaching for your smartphone on the train—happen automatically—controlled by structures such as the basal ganglia, located beneath the cerebral cortex.

This has a clear advantage: it takes the strain off your system. You don’t have to constantly rethink how you behave. Your body knows the routine. This allows your brain to conserve cognitive resources—capacity that you then need for decisions that truly require your attention. The more everyday behaviors happen automatically, the more room there is for what really matters. Overall, habits provide a sense of security —even when they aren’t actually good for you.

As soon as you try to change something, something crucial happens in the background: Your system has to take active control again. This costs energy and is often perceived by the nervous system as a burden or stress. That’s why new routines often feel unfamiliar or exhausting at first—not because they’re wrong, but because they haven’t become automatic yet.

This key insight is therefore important: Behavioral change depends less on sheer willpower than we often think. What matters is how we actively harness neurobiological processes—such as habit automation and reward-based learning—to our advantage. And that’s exactly why small, gradual changes work significantly better than radical upheavals.

The Change of Seasons as a Biological Window

The transition from winter to spring isn’t just noticeable on the outside—it also changes how your body functions. Changes in light conditions have been shown to affect sleep quality, mood, and activity levels. For example, the morning rise in cortisol—known as the cortisol awakening response—tends to be more pronounced in spring due to earlier exposure to light, helping us feel more alert and active in the morning. With more daylight, your sleep-wake cycle shifts. You wake up earlier, are often a bit more active in your daily life, but sometimes also feel unusually tired at first—hence the term “spring fatigue.”

In short: Your body is already in adjustment mode.

Whether this state generally makes the brain more plastic for new habits has not yet been conclusively proven scientifically. But the fact is: When your mood and energy levels rise, the perceived barrier to adopting new behaviors decreases—and that’s a real advantage.

Microhabits Instead of an All-Out Program

If you want to make a change, it’s tempting to start “right” from the get-go: more exercise, a healthier diet, getting up earlier, trying out new hobbies. In practice, this rarely works in the long run.

What works much better are small, realistic steps—so-called microhabits. These can be very simple things:

• Spending 5 minutes outside in the morning sunlight
• 10 minutes of mobility exercises or light movement after work
• A short breathing exercise before bed
• putting your phone away 30 minutes earlier
• Eating a serving of vegetables and/or fruit with every meal
• Take a moment to pause and reflect once a day
• Invest one hour a week in an online course

This may seem unspectacular. But that’s exactly the point. Your brain responds not only to major changes, but above all to repetition and small successes. Every step you take gives your system positive feedback. Neurobiologically, dopamine also plays a role here—a neurotransmitter that supports motivation and learning processes.

It’s important to note that dopamine responds particularly strongly to achievable goals. If you set your sights too high, this feedback often fails to materialize. Small steps, on the other hand, regularly create the feeling: “That worked.”

At the same time, your nervous system benefits from this approach. Small changes feel less threatening, cause less stress, and are easier to integrate into existing routines. This creates a sense of security —a key prerequisite for actually sticking with something.

Ultimately, it’s not intensity that matters, but consistency.

Spring Also Brings Restlessness and Tension

Not everyone experiences spring as a time of renewal. For some, this season feels more unsettling—with fluctuating energy, inner tension, or the feeling of not quite “being there.”

This isn’t because something is wrong, but because of how sensitively your nervous system reacts to change. More light, longer days, and increased activity also mean more stimuli for the body. These can activate the system—sometimes more intensely than feels good at first.

Especially when your body is already under strain—due to stress, lack of rest, or poor sleep—this additional stimulation can lead to restlessness rather than clarity.

That’s why it’s important to remember: Not every adjustment feels positive right away. Even phases that seem unstable or exhausting to you can be part of an adjustment process. What matters is how you handle it—and whether you give your system enough space to regulate itself at its own pace.

If you feel more restless than energetic, it can help to specifically regulate your nervous system. You can read about how that works here: Calming the Nervous System.

Conclusion: Not a Fresh Start—But a Conscious Fine-Tuning

Spring symbolizes a fresh start. More energy, more motivation, more movement. But that’s exactly where the challenge lies.

It’s not about doing everything differently right now. Nor is it about suddenly functioning “better.” Spring isn’t a competition. It’s more of an invitation to take a closer look:

What’s good for you right now? Where can you make small adjustments that feel realistic?

Instead of radical changes, it’s about fine-tuning. Small steps that your body can keep up with. Routines that don’t put pressure on you, but support you.

Because lasting change doesn’t come from “more, more, more”—but from microhabits, repetition, stability, and feeling good in your body. Or to put it another way: not everything new, but a little bit better every day.
