Daylight Saving Time And Circadian Rhythm: Tips To Sleep Better

You know that feeling the morning after the clocks change, when your alarm goes off and your whole body says, “absolutely not”?

You are not lazy. Your circadian rhythm, your internal 24-hour clock, is just out of sync — just like your clock on the microwave, you have to reset to match the new reality. Adjusting to daylight saving time is basically a tiny case of jet lag, except you never got the fun airport cocktail or the vacation photos to show for it.

In this guide, we will walk through what your circadian rhythm actually does, why a simple one-hour shift can feel so rough, and practical ways to reset after the time change. 

What Your Circadian Rhythm Actually Does

Your circadian rhythm is your body’s built-in timekeeper. It helps set the schedule for things like:

• When you feel sleepy or alert

• When hormones rise and fall

• Your body temperature and digestion

A tiny structure in the brain, the suprachiasmatic nucleus, acts as the master clock and takes its main cue from light. Morning light tells your brain it is daytime, helping to shut down melatonin, the hormone that makes you feel sleepy. Evening darkness signals that it is time to release more melatonin so you can drift off.

When your light schedule matches your sleep and wake times, your circadian rhythm runs fairly smoothly. When the clocks change overnight, that alignment gets bumped. Your body is still on “old time” while your calendar and alarms have jumped ahead or back.

Why A One-Hour Time Change Feels So Rough

On paper, one hour does not sound like much. In real life, it can feel like a lot. Studies have linked the switch to daylight saving time with:

• Shorter sleep and more tiredness in the days after the change

• Misalignment between the body clock and the social clock - things like school and work start times

• Potential effects on mood and concentration

Sleep and circadian researchers often call this “social jet lag:” your social schedule has jumped to a new time zone, but your internal rhythm is lagging a step behind.

The spring change, when we lose an hour, tends to be the hardest. Losing sleep plus suddenly darker mornings makes it tougher for your brain to get a clear “daytime” signal. Reviews of the research suggest that this spring shift disrupts people the most, especially for those who are already sleep deprived.

The good news is that for many people, the circadian rhythm adjusts within a few days. Others, especially those with existing sleep issues, high stress, chronic conditions or shift work, may feel off for longer and need more deliberate support.

What This Looks Like In Real Life

If daylight saving time has ever left you feeling “off,” it often shows up as:

• The morning zombie: Your alarm goes off at the same time, but your body feels like it is too early. You hit snooze, feel foggy at work, and cravings for sugar and coffee creep in.

• The wired but tired bedtime: You lie down at your usual time, but your brain still feels in “day mode.” You scroll, toss, and end up falling asleep later.

• The kid chaos effect: Young children and pets do not care what the clock says. They still wake up or demand food according to their internal schedule, while you are trying to reset yours.

Layer on stress, anxiety, or an already fragile sleep routine, and that small clock change can ripple through your whole week.

Spring Forward And Fall Back: Why They Feel Different

Both directions tug on your circadian rhythm, but in slightly different ways.

Fall back

You gain an hour on the clock, but that does not always equal extra rest. Many people naturally wake at their old time, then feel sleepy earlier in the evening. Parents often notice this the most in their kids.

Spring forward

You lose an hour of sleep unless you plan ahead. Mornings are darker, evenings are lighter, and your natural cues shift later. That often means:

• Trouble getting up on time

• Feeling sleepy or distracted in the morning

• A later “sleepiness window” at night, which can tempt you to stay up even later

In both cases, your goal is the same: gently guide your body clock toward the new time rather than expecting it to leap overnight.

Sleep Tips To Protect Your Rhythm

Here are practical, evidence-informed ways to make the transition easier on your circadian rhythm. You can pick a few that feel realistic for your life.

Shift Your Schedule Gradually

Rather than flipping your sleep by a full hour in one go, start making small changes a few days before the time change if you can.

• Move your bedtime and wake time by 15 to 20 minutes each day toward the new clock time.

• Do the same with fixed points in your day, like meals or your regular workout.

Research suggests that these gradual steps give your internal clock time to adjust and can soften the hit of the time change.

If you forgot to plan ahead (which happens to all of us), you can still use this gradual approach in the week after the change.

Use Light As Your Secret Tool

Light is the strongest cue for circadian rhythm, so use it to your advantage when the clocks change. 

• In spring, try to get outside in the morning, even for a short walk, to reinforce “this is daytime” to your brain.

• In both spring and fall, dim overhead lights in the hour before bed and reduce bright screen exposure as much as you reasonably can.

• If mornings are very dark where you live, some people find a dawn simulator or light box helpful, especially when used under the guidance of a health professional.

You do not need a perfect routine. Even a small bump in morning light and a slightly softer evening environment can support your body clock.

Step Up Your Sleep Hygiene Around The Time Change

Think of the week around daylight saving time as “sleep gentle mode.” A few simple habits can make a big difference:

• Keep roughly the same wake time every day, even on weekends.

• Aim for a calming, predictable wind-down routine before bed, such as a warm shower, light stretching, or quiet reading.

• If you need a nap, keep it short, around 20 to 30 minutes, and earlier in the day so it does not steal sleep from the upcoming night.

Support Your Body With Food And Movement

Your circadian rhythm also responds to when you move and eat.

• Try to keep meals at relatively consistent times day to day.

• Go for light to moderate movement, like a walk, gentle yoga, or an easy bike ride. This can help you feel more alert by day and pleasantly tired by night.

• Avoid large, late dinners and heavy snacks right before bed, which can make your body feel busy digesting when you want to wind down.

You do not need to overhaul your entire diet or training plan. Think of it as nudging your existing habits slightly earlier or later to match the new clock.

Calm The Mind, Not Just The Clock

For many people, the hardest part of the time change is managing the racing thoughts that show up the moment the lights go out.

You might notice:

• Worrying that you will not be able to function the next day

• Frustration that “everyone else seems fine”

• Old habits of doom scrolling or checking the clock over and over

This is where gentle, realistic expectations help. A slightly off week does not mean your sleep is broken forever. It means your system is adapting.

Short wind-down rituals can ease your mind into night mode, such as:

• A few minutes of relaxed breathing

• Listening to calming, low-intensity music

• Journaling a quick “to-do tomorrow” list so you are not trying to remember everything in bed

What If You Already Have Insomnia Or A Fragile Sleep Schedule?

If you are already dealing with insomnia, anxiety, ADHD, shift work, or high stress, the time change can feel like someone bumped a shaky table. In that case, it is worth being even more deliberate.

You might:

• Start shifting your schedule a week in advance instead of a few days

• Prioritize morning light and consistent routines a few weeks after the change

• Be gentler with your expectations of productivity on the first couple of days

If you’re experiencing poor sleep, low mood, or daytime sleepiness for several weeks despite your best efforts, it is a good idea to talk with a health care provider or sleep specialist. They can help check for medical sleep disorders and guide you to treatments that fit your situation.

How Dreamwell Can Help

You can’t control whether we get rid of daylight savings time, but you can shape the environment you fall asleep in.

So, where does a sleep music app realistically help?

Dreamwell offers sounds designed for specific sleep challenges, such as stress, overthinking, anxiety, ADHD, sound masking, and insomnia. If your main problem around the time change is:

• Extra noise from roommates or neighbours at new hours, you might lean on sound masking tracks.

• A mind that will not stop planning tomorrow’s agenda, you might choose tracks tuned for overthinking or anxiety.

• A bedtime that drifts later and later, you might build a consistent bedtime routine to signal that it is wind-down o’clock.

Music gives your brain a reliable cue: when your favourite audio starts, it is time to shift from busy to sleepy. Over days and weeks, that repetition helps your circadian rhythm learn the pattern to get back to normal again.

Daylight saving time can be a bane to your circadian rhythm, but understanding how your internal clock works (and how light, timing, and routine interact with it) can make the transition feel less like chaos and more like a small, manageable adjustment.

Start with one or two changes that feel doable, like a gradual shift in bedtime and a bit more morning light. Add in calming night rituals and realistic expectations. 

If you want extra support while you reset, try Dreamwell as your nightly wind-down companion and let its tailored sleep music help your body remember how to rest again.
