Sarah Martinez thought she had beaten the winter blues. After months of dark mornings and freezing commutes, the 34-year-old marketing manager from Denver was thrilled to see daylight stretching past 6 PM again. She felt energized, motivated, ready to tackle spring with renewed vigor.
Then came the Monday after daylight saving time kicked in. Sarah dragged herself out of bed feeling like she’d been hit by a truck. Her usual morning coffee didn’t help. By 2 PM, she could barely keep her eyes open during meetings. “I felt completely wiped out for no reason,” she recalls. “It was like someone had drained my battery overnight.”
Sarah isn’t alone. Medical experts are warning that millions of people are about to experience a wave of extreme fatigue in the coming weeks, and the culprit might surprise you.
The Spring Energy Crash Nobody Talks About
While most people celebrate the arrival of longer days and warmer weather, sleep specialists are bracing for what they call “the spring slump.” The trigger isn’t a new virus or workplace stress—it’s the seemingly innocent ritual of moving our clocks forward one hour for daylight saving time.

“Moving the clock forward doesn’t sound dramatic, yet for our internal body clock, it can feel like mild jet lag that lasts days or even weeks,” explains Dr. Rachel Chen, a circadian rhythm specialist at Johns Hopkins Sleep Center.
Unlike the fall time change, which gives us an extra hour of sleep, the spring shift robs us of precious rest time. That missing hour creates a ripple effect that can leave people feeling exhausted for weeks.
The extreme fatigue hits some groups particularly hard. Children, teenagers, and anyone already dealing with sleep deprivation face the biggest challenges. Shift workers and people with existing sleep disorders often struggle the most.
Why Your Body Rebels Against “Spring Forward”
Your body operates on an internal 24-hour clock called the circadian rhythm. This biological timekeeper controls everything from when you feel sleepy to when your body temperature peaks. It’s incredibly sensitive to light exposure, especially in the morning.
Here’s what happens when we spring forward:
- Sunrise appears later: Your brain gets confused signals about when the day actually begins
- Sleep-wake cycle disruption: Your internal clock falls out of sync with your daily schedule
- Hormone imbalance: Cortisol and melatonin production gets thrown off track
- Cognitive fog: Concentration and decision-making abilities suffer
- Mood changes: Irritability and anxiety levels can spike temporarily
“Less morning light pushes the internal clock later, which makes it harder to fall asleep on time and harder to wake up refreshed,” notes Dr. Michael Torres, a sleep medicine physician at Stanford University.
Research shows the effects aren’t just psychological. Studies have documented increased rates of heart attacks, strokes, and accidents in the weeks following the spring time change. Even seemingly healthy adults can experience significant drops in alertness and reaction time.
| Symptom | Peak Impact Period | Typical Duration |
|---|---|---|
| Extreme fatigue | Days 1-5 | 1-3 weeks |
| Sleep difficulty | Days 2-7 | 2-4 weeks |
| Mood changes | Days 1-10 | 1-2 weeks |
| Concentration issues | Days 3-14 | 2-3 weeks |
| Appetite changes | Days 2-8 | 1-2 weeks |
Who Gets Hit Hardest by the Fatigue Wave
Not everyone experiences extreme fatigue equally during the spring transition. Certain groups face much greater challenges adapting to the time change.
Teenagers and young adults often struggle the most. Their natural circadian rhythms already lean toward later bedtimes and wake-up times. The spring shift amplifies this tendency, making it even harder to maintain normal sleep schedules.
Parents with young children face a double whammy. Kids under 10 typically have more rigid internal clocks and may take longer to adjust. This means cranky, overtired children combined with sleep-deprived adults—a recipe for family stress.
Shift workers and healthcare professionals experience particularly severe effects. Their already disrupted sleep patterns get further scrambled by the time change. Emergency rooms often see upticks in accidents and medical issues during this period.
“We consistently see more workplace injuries, car accidents, and even heart attacks in the two weeks following daylight saving time,” says Dr. Amanda Foster, an occupational health specialist. “The extreme fatigue people experience is real and measurable.”
People with existing sleep disorders, depression, or anxiety face heightened symptoms. The time change can trigger longer-lasting mood disruptions and worsen underlying conditions.
Your Battle Plan Against Spring Fatigue
The good news? You don’t have to surrender to extreme fatigue this spring. Sleep experts have developed proven strategies to minimize the impact of daylight saving time on your energy levels.
Start preparing your body several days before the time change. Gradually shift your bedtime earlier by 15-20 minutes each night in the week leading up to the switch. This gentle transition helps your internal clock adjust more smoothly.
Light exposure becomes your secret weapon against fatigue. Get outside within 30 minutes of waking up, even if it’s cloudy. Morning sunlight helps reset your circadian rhythm faster than any other intervention.
Strategic caffeine use can help, but timing matters. Limit coffee and tea to morning hours only. Caffeine consumed after 2 PM can interfere with nighttime sleep, creating a vicious cycle of fatigue.
Create a consistent evening routine that signals bedtime to your brain. Dim the lights, avoid screens for at least an hour before sleep, and keep your bedroom cool and dark. These simple steps help combat the sleep disruption that fuels extreme fatigue.
Consider short power naps if you’re struggling during the day, but keep them under 20 minutes and before 3 PM. Longer naps or late-day rest can make nighttime sleep even more difficult.
Exercise can help reset your internal clock, but avoid intense workouts within four hours of bedtime. A brisk morning walk or gentle stretching session works better than high-intensity evening gym sessions during this transition period.
FAQs
How long does extreme fatigue from daylight saving time typically last?
Most people adjust within 1-3 weeks, though some individuals may feel effects for up to a month. Children and people with sleep disorders often need longer recovery periods.
Is it normal to feel more tired in the spring than during fall time changes?
Yes, spring forward is universally harder on the body than fall back because you lose an hour of sleep rather than gaining one. The extreme fatigue is a normal biological response.
Should I take melatonin supplements to help with the transition?
While some people find low-dose melatonin helpful, consult your doctor first. Timing and dosage matter significantly, and it’s not right for everyone.
Can drinking more coffee help combat the extreme fatigue?
More coffee often backfires by disrupting sleep further. Stick to your normal caffeine intake and focus on morning consumption only.
Do light therapy lamps help with daylight saving time adjustment?
Light therapy lamps can be effective, especially for morning use. Look for lamps that provide 10,000 lux and use them for 20-30 minutes after waking.
Why do some people seem unaffected by the time change?
Natural early risers and people with very consistent sleep schedules tend to adapt more easily. Age, genetics, and overall health also play roles in how severely someone experiences the transition.
