7 Ways to Reset a Disrupted Sleep-Wake Cycle

Resetting your sleep-wake cycle doesn't have to be complicated. Here are seven simple, science-backed strategies to improve your sleep:

1. Control Light Exposure: Get natural sunlight in the morning and reduce artificial light in the evening.

2. Adjust Bedtime Gradually: Shift your sleep schedule in 15–30 minute increments to avoid sudden changes.

3. Create a Nightly Routine: Wind down with relaxing activities like stretching, meditation, or journaling.

4. Limit Screen Time at Night: Avoid screens an hour before bed to prevent melatonin suppression.

5. Time Meals Wisely: Eat at consistent times and avoid heavy meals close to bedtime.

6. Exercise at the Right Time: Morning or early afternoon workouts are best; avoid intense evening exercise.

7. Use Melatonin Properly: Start with a low dose (0.5–1 mg) 30–60 minutes before bed if needed.

Quick Tip: Consistency is key. Stick to the same sleep and wake times daily, even on weekends, for better results.

How to Reset Your Circadian Rhythm / Body Clock | Sleep Reset

1. Control Your Light Exposure

Managing light exposure is essential for keeping your body's internal clock - or circadian rhythm - on track. By soaking up natural light during the day and cutting back on artificial light in the evening, you can help regulate your sleep-wake cycle more effectively.

Get Morning Sunlight

Start your day with exposure to natural light. Whether it's stepping outside for a few minutes or sitting by a sunny window, morning light signals your body that it's time to wake up and be alert. This simple habit can make a big difference in how energized you feel throughout the day. Tools like Healify can even monitor your light exposure and its impact on your sleep patterns.

Reduce Evening Light

As evening approaches, it’s time to dial down the brightness. Dimming artificial lights and avoiding screens before bedtime can help your body transition into sleep mode. Healify can assist by tracking your evening habits and sending reminders to reduce light exposure, making it easier to stick to a healthy routine.

2. Change Your Bedtime in Small Steps

Making big changes to your bedtime all at once usually backfires. Instead of jumping to a drastically earlier or later bedtime, try adjusting it in small steps - just 15–30 minutes at a time. This gradual shift gives your body the chance to adapt without causing sleep deprivation, daytime grogginess, or other disruptions. Your internal clock works best with gentle nudges, not sudden changes.

For example, if your current bedtime is midnight, you can ease into an earlier schedule as shown below:

Notice how bedtime and wake time are adjusted together. This helps maintain your total sleep duration while gradually shifting your schedule. Pairing these changes with exposure to natural light during the day can further support your body’s adjustment.

Healify can simplify this process by tracking your progress and sending you reminders to stick to your new schedule. The app uses AI to analyze your sleep patterns and determine how quickly you can safely shift your bedtime, ensuring the pace feels manageable.

Here are a few tips to make this transition smoother:

• Stick to your new schedule every day: Consistency is key to success.

• Pay attention to how you feel: Keep track of your energy levels and sleep quality.

• Be patient: It may take 1–2 weeks for your body to fully adjust to significant changes.

3. Set Up a Nightly Routine

Having a consistent nightly routine helps signal your body that it’s time to wind down, making it easier to fall asleep naturally. Studies have shown that people who stick to regular bedtime habits tend to fall asleep faster and enjoy better-quality sleep.

Pre-Sleep Relaxation Methods

Engaging in calming activities before bed can make a big difference. Here’s a simple 30-minute routine that promotes relaxation and prepares your mind and body for rest:

The key is consistency. Try to start your wind-down routine 60–90 minutes before bedtime every evening. Over time, this habit reinforces your body’s natural sleep-wake cycle.

Here are a few additional techniques to enhance your routine:

• Practice deep breathing, like the 4-7-8 method, to calm your nervous system.

• Write down tasks for the next day to declutter your mind.

• Read a physical book under soft, warm lighting.

• Listen to soothing music or nature sounds to create a peaceful atmosphere.

4. Cut Back on Screens at Night

Using screens in the evening can interfere with your sleep. It suppresses melatonin production, makes it harder to fall asleep, and often leads to restless nights.

Create a No-Screens Window

Try turning off your devices at least an hour before bedtime. Use this time to unwind with activities like reading a book, listening to calming music, or practicing meditation. If you absolutely need to use a device, switch on Night Mode and dim the brightness to minimize blue light exposure. This approach ties into earlier tips about managing light, but focuses specifically on the impact of screens.

For a more personalized approach, Healify's sleep tracking features can help. The app monitors your screen habits alongside your sleep patterns, offering tailored suggestions to fine-tune your nighttime routine and improve your rest.

5. Time Your Meals for Better Sleep

When it comes to improving your sleep, adjusting your meal timing can be just as important as managing light exposure and screen time. Your eating schedule plays a key role in syncing your circadian rhythm, which directly impacts the quality of your sleep. Sticking to consistent meal times helps reinforce your body’s internal clock, making it easier to fall asleep and wake up feeling refreshed.

With tools like Healify, you can take this a step further. By tracking your eating habits alongside your sleep patterns, Healify provides tailored meal timing recommendations to help you maintain a healthier and more balanced daily routine.

6. Pick the Best Time to Exercise

The timing of your workouts can play a key role in improving your sleep. While staying active is essential for better rest, when you choose to exercise can make a big difference in how well your body winds down at night.

Morning workouts, especially outdoors, combine physical activity with exposure to natural light, which helps regulate your circadian rhythm. Exercising in the early afternoon can also be effective - your body temperature naturally rises during this time, and the gradual cool-down afterward can prepare you for restful sleep.

What to avoid? Intense exercise too close to bedtime. Activities like running, HIIT, or heavy strength training in the evening can elevate your core temperature and adrenaline levels, making it harder to relax and fall asleep. Ideally, you should finish vigorous workouts at least 2-3 hours before heading to bed.

Here’s a quick breakdown of the best workout times and their effects on sleep:

Healify’s AI-powered health coach takes into account your daily routine, stress levels, and sleep data to recommend workout times tailored to your needs. By following these personalized suggestions, you can ensure your fitness routine supports your sleep-wake cycle rather than disrupting it.

7. Use Melatonin Supplements Correctly

Melatonin is a hormone naturally produced by the pineal gland when it’s dark. It plays a key role in regulating your internal clock, making it a helpful tool for resetting a disrupted sleep-wake cycle when used the right way.

For the best results, take melatonin 30 to 60 minutes before your intended bedtime.

It’s always a good idea to start low - begin with 0.5 mg and adjust as needed based on how your body responds. Research suggests that smaller doses can shorten the time it takes to fall asleep by an average of 7–12 minutes.

Important Considerations

Avoid taking melatonin if you’re using:

• Blood thinners

• Diabetes medications

• Sedatives

These combinations can interfere with your health, so it’s crucial to be cautious.

Maximizing Effectiveness

To get the most out of melatonin supplements, pair them with habits that naturally boost your body’s melatonin production. For example, reducing exposure to blue light in the evening can help prevent the suppression of melatonin, especially light in the 460 nm wavelength range. Combining these habits with your overall sleep routine can make a noticeable difference.

If you’re looking for extra guidance, Healify’s sleep tracking features can help. The app’s AI health coach analyzes your sleep patterns and offers personalized suggestions, including the best time to take melatonin based on your unique circadian rhythm.

When to Seek Professional Guidance

Before starting melatonin supplements, consult a healthcare provider if you:

• Take other medications

• Have any underlying health conditions

• Are pregnant or breastfeeding

• Plan to use melatonin long-term

FAQs

What’s the best way to adjust my sleep schedule if I work irregular hours?

Adjusting to an irregular work schedule can throw your sleep routine off balance, but with some focused strategies, you can make it work. The first step is to pinpoint the most consistent time you have available for rest, even if it varies day-to-day. Once you identify that window, try to create a routine by sticking to the same bedtime and wake-up time whenever possible.

Here are a few tips to help reset your sleep schedule:

• Be mindful of light exposure: During your waking hours, make an effort to get plenty of bright light, preferably natural sunlight. On the flip side, reduce light exposure - especially from screens - close to bedtime to help your body prepare for sleep.

• Create a relaxing bedtime routine: Activities like reading a book, meditating, or even taking a warm shower can help signal your body that it’s time to wind down.

• Steer clear of stimulants: Avoid caffeine, energy drinks, and heavy meals in the hours leading up to your sleep time, as these can interfere with your ability to fall asleep.

For more tailored advice, you might want to check out the Healify app. It uses your lifestyle and personal data to offer customized recommendations, making it easier to manage your sleep-wake cycle - even when your schedule is all over the place.

What are some natural ways to reset your sleep-wake cycle if you can't take melatonin due to medication interactions?

If melatonin isn't an option for you, there are several natural ways to help reset your sleep-wake cycle:

• Get some sunlight: Spending time in natural light, especially in the morning, can help regulate your internal clock. In the evening, dimming the lights sends a signal to your brain that it’s time to wind down.

• Stick to a schedule: Going to bed and waking up at the same time every day - even on weekends - can help your body maintain a steady rhythm.

• Cut back on screens before bed: Blue light from screens can mess with melatonin production, so try to avoid them at least an hour before bedtime.

In addition, a relaxing bedtime routine, like reading, meditating, or soaking in a warm bath, can cue your body that it’s time to unwind. For more tailored advice, the Healify app offers personalized insights to improve your sleep and overall health by analyzing your unique data.

How does morning sunlight impact my sleep-wake cycle and energy levels during the day?

Exposure to natural light in the morning plays a key role in keeping your circadian rhythm - your body’s internal clock - on track. Morning sunlight sends a clear signal to your brain that it’s time to wake up and get moving. This triggers the release of hormones like cortisol, which helps boost your energy and alertness. At the same time, it dials back melatonin, the hormone responsible for making you feel drowsy, so you’re more awake and focused during the day.

Spending just 15–30 minutes outside in the morning can do wonders for your sleep. It not only improves the quality of your rest but also makes falling asleep at night much easier. If stepping outside isn’t an option, sitting by a window or using a light therapy box can offer similar perks.
