Yesterday morning I woke up and everything just felt… off.
And I don’t even want to talk about how I feel today!

Not sick. Not exhausted. Just weird.

My brain felt foggy, my appetite was strange, and I had that feeling like my body hadn’t quite caught up with the day yet. I went outside for a bit, made breakfast and coffee, sat down at my computer, and just stared at the screen for a minute thinking, what is wrong with me today?

And then it clicked.

Daylight Saving Time.

Every year this happens and every year people think they’re imagining it. They’ll say things like “I don’t know why I feel so out of it today” or “Why am I so tired?” and assume it’s stress, bad sleep, or just life being busy.

But the reality is that this one hour shift actually throws your entire system off.

And the funny part is the reason it exists in the first place.

Daylight Saving Time started during World War I. The idea was simple: if we moved the clocks forward, people would have more daylight in the evening and theoretically use less electricity. It was basically an energy-saving strategy. The U.S. brought it back during World War II and eventually it just stuck.

The problem is our bodies never signed up for that agreement.

Your body runs on something called a circadian rhythm. Think of it like your internal clock. But it’s not controlled by the numbers on your phone. It’s controlled by light.

When sunlight hits your eyes in the morning, your brain releases hormones that wake your body up. Cortisol rises. Dopamine kicks in. Your metabolism starts ramping up. Digestion turns on.

As the sun goes down, that whole system slowly shifts gears. Melatonin rises. Your nervous system calms down. Your body prepares for sleep.

It’s an incredibly precise system. Hormones, digestion, mood, brain function, metabolism… they’re all following the rhythm of light.

Then once a year we basically say, “Let’s just move everything forward an hour and hope for the best.”

Your body has absolutely no idea that just happened.

Your brain is still operating on yesterday’s timing while the world is suddenly asking you to wake up earlier, eat earlier, work earlier, and go to sleep earlier.

So for a few days, everything feels a little off.

It’s basically jet lag without getting on a plane.

You might notice mornings feel harder. Your sleep feels lighter. Your energy dips earlier in the afternoon. Maybe you’re hungrier than usual or craving sugar more than normal.

Your body is just trying to recalibrate.

What’s interesting is research actually shows spikes in things like car accidents, heart attacks, and workplace injuries right after the spring time change. When circadian rhythms get disrupted, the ripple effects show up everywhere.

The good news is your body is incredibly adaptable. It just needs the right signals to find its rhythm again.

And the biggest signal your body understands is light.

Getting outside in the morning is one of the most powerful things you can do. When sunlight hits your eyes early in the day, it tells your brain “this is the new morning.” Your hormones start shifting to match the new schedule.

Then in the evening, doing the opposite helps. Our modern world is flooded with bright light at night, which can delay melatonin and make it harder for your brain to adjust. Turning lights down, stepping away from screens earlier, or just creating a calmer nighttime environment helps your body settle into sleep.

Movement helps too. Walking, lifting, being outside… all of that reinforces your circadian rhythm.

And honestly the other big thing is just giving yourself a little grace for a few days.

If you feel a little slower, a little hungrier, a little foggier… nothing is wrong with you.

Your body is just trying to catch up with a clock it never asked for.

And the irony of all of this is that we originally changed the clocks to save electricity, but in the process we end up temporarily confusing the very system that regulates our sleep, metabolism, mood, hormones, and brain function.

Your body will figure it out though. It always does.

Sunlight in the morning, darker evenings, a little movement, and a little patience… and within a few days your rhythm will find its groove again.

Quick checklist to beat daylight saving time fatigue

-Get outside for morning sunlight within the first hour of waking

-Move your body during the day (even a simple walk helps)

-Keep your evening lights dim, wear blue light blocking glasses and limit screens before bed

-Eat meals at consistent times to anchor your body clock

-Go to bed a little earlier for a few nights if you feel tired

-Hydrate and prioritize real food to support energy

Give your body a few days. It’s smarter than any clock we’ve ever invented.

Hang in there!
