Why You Feel So Tired After “Spring Forward” (And What to Do About It)

If you’re in Concord, NC, and feeling extra tired this Monday morning, you’re not alone. The Monday after daylight saving time is famous for leaving people feeling sluggish and low on energy. Even if you went to bed on time, your body may still feel like it’s waking up an hour earlier than normal. Understanding how the time change affects your sleep—and what you can do to help your body adjust—can make the transition much easier.

It’s Monday morning after the time change… and if you feel like you’re dragging today, you’re definitely not imagining it.

You went to bed at the right time.

Your alarm went off at the right time.

But your body knows something your clock doesn’t.

Even though the clock says it’s time to wake up, your internal body clock still thinks it’s an hour earlier. That mismatch is exactly why the Monday after the spring daylight saving change is often nicknamed “Sleepy Monday.” 

Let’s talk about why this happens—and what you can do to help your body adjust faster.

Why Daylight Saving Time Throws Your Body Off

Your body runs on something called a circadian rhythm—your internal 24-hour clock that regulates sleep, hormones, energy levels, appetite, and even mood.

This rhythm is heavily influenced by light and darkness, which signal when it’s time to wake up or wind down.

When we “spring forward,” we suddenly lose an hour of sleep and shift our schedules earlier than our bodies expect.

Experts often compare this to mild jet lag.

That one-hour shift can lead to:

• Increased fatigue and grogginess

• Trouble falling asleep at night

• Reduced concentration and productivity

• Mood changes or irritability

• Increased cravings for high-energy foods

Research also shows that the days immediately following the time change can bring measurable impacts:

• Fatal car accidents increase by about 6% after the spring shift.

• There are spikes in heart attacks and strokes in the days after the change.

• Many people experience sleep disruption that can last several days to a week while the body adjusts.

So if today feels harder than usual, you’re in very good company.

How Long Does It Take to Adjust?

Most people start to feel normal again within a few days to about a week, depending on their sleep habits and schedule.

The good news: there are simple things you can do to help your body reset faster.

Tips to Reset Your Body After the Time Change

1. Get Morning Sunlight

Natural light is one of the most powerful signals for your body clock.

Even 10–20 minutes of morning sunlight helps shut down melatonin (the sleep hormone) and tells your brain it’s time to be awake.

Morning light also helps set your internal clock so you feel sleepy at the right time that night.

Simple idea:

Take a short walk, open the blinds, or drink your coffee outside.

2. Stick to a Consistent Sleep Schedule

Your circadian rhythm loves routine.

Going to bed and waking up at the same time every day—even on weekends—helps reinforce your sleep cycle. 

Consistency is one of the fastest ways to recover after the time change.

3. Move Your Body During the Day

Physical activity improves sleep quality and helps regulate your internal clock.

Daylight saving time often brings more daylight hours, which naturally encourages movement and outdoor activity.

Exercise is also one of the best ways to reset your body clock and improve sleep quality. Even light to moderate activity helps boost energy during the day and makes it easier to fall asleep at night.

4. Be Careful With Afternoon Caffeine

Caffeine can stay in your system up to 10 hours and may interfere with sleep later that night.

If you’re already adjusting to the time change, late-day caffeine can make falling asleep even harder.

5. Avoid Heavy Screen Time Late at Night

Bright light from phones, tablets, and TVs can trick your brain into thinking it’s still daytime.

Reducing screen exposure in the evening helps your body produce melatonin and prepare for sleep.

6. Aim for 7–9 Hours of Sleep

Sleep experts recommend adults aim for 7–9 hours of sleep each night to maintain energy, focus, and overall health.

If you’re feeling extra tired this week, prioritize sleep when you can.

The Bottom Line

If today feels harder than usual, it’s not just in your head.

Your body is simply adjusting to a new schedule.

The good news is that with a little sunlight, movement, and consistent sleep habits, most people get back to normal within a few days.

Until then, give yourself a little grace this week. Your body is just catching up with the clock.
