Resetting your sleep schedule can be challenging, but melatonin can be an effective solution to get you back on track. Melatonin is a hormone naturally produced by the body when darkness falls, promoting sleep by putting you in a state of quiet wakefulness. While most people produce enough melatonin, certain conditions like jet lag, night shift work, or being a night owl can cause misalignment in your sleep schedule and circadian rhythm. In such cases, melatonin supplements can help reset your sleep cycle by facilitating sleep-phase advances and training your body to align with a traditional 24-hour cycle. The recommended dosage varies, with some sources suggesting 1-3 milligrams, while others recommend 0.5 or 3.0 milligrams, taken 1-2 hours before bedtime. It's important to note that melatonin should be used short-term, and if it doesn't help after a week or two, it's best to discontinue use and consult a healthcare provider. Additionally, gradual adjustments to your sleep schedule, consistent wake-up and bedtime, and good sleep hygiene habits are crucial for successfully resetting your sleep cycle.

What You'll Learn
Melatonin dosage and timing
Melatonin is a hormone that is naturally produced by the body when it gets dark, making you feel drowsy and preparing you for sleep. The hormone melatonin does not make you sleep, but it puts you into a state of quiet wakefulness that helps promote sleep.
If you are experiencing insomnia, jet lag, or are a night owl who needs to get to bed earlier, you can try melatonin supplements to kickstart a new sleep pattern. Melatonin supplements can help you feel sleepy when you usually wouldn't and shift the timing of your sleep cycle. Thorne's Melaton-3, which contains 3 mg of melatonin per capsule, helps maintain your normal sleep-wake cycle, otherwise known as your circadian rhythm. Research indicates that melatonin decreases the amount of time it takes to fall asleep, improves the ability to stay asleep, and improves the length of deep sleep.
It is recommended to take 1 to 3 milligrams of melatonin, two hours before bedtime. To ease jet lag, you can try taking melatonin two hours before your bedtime at your destination, starting a few days before your trip. You can also adjust your sleep-wake schedule by staying awake when you reach your destination and delaying sleep until your usual bedtime in the new time zone. If melatonin for sleep isn't helping after one or two weeks, it is recommended to stop using it. Melatonin is safe for most people to take nightly for one to two months. After that, it is suggested to stop taking it and observe how your sleep is.
To make the most of your natural melatonin production, you can get exposure to daylight during the morning and afternoon. You can try going for a walk outside or sitting beside a sunny window. It is also important to keep the lights low in the evening to help your mind and body prepare for sleep. Blue and green light from electronic devices can neutralize melatonin's effects, so it is recommended to stop using your computer, smartphone, or tablet a few hours before bedtime.

Light exposure and sleep
Light exposure plays a crucial role in regulating sleep. Our bodies are programmed to respond to light and darkness, which helps to maintain a healthy sleep-wake cycle, or circadian rhythm. When our eyes are exposed to light, the brain sends signals associated with wakefulness, while decreased light exposure at night promotes relaxation and sleep.
However, with the advent of electricity and electronic devices, our exposure to artificial light has increased significantly. This can disrupt the natural circadian rhythm, as the brain also responds to artificial light. Constant exposure to indoor lighting and blue light from electronic devices can interfere with the body's ability to distinguish between day and night, negatively impacting sleep.
To reset your sleep schedule, it is important to manage your light exposure. Here are some strategies to consider:
- Get early light exposure: Expose yourself to natural light early in the morning. Go for a walk or sit by a sunny window. This helps to bring forward your circadian rhythm.
- Limit evening light exposure: Dim the lights about 90 minutes before bedtime. Avoid late-night screen time, as the blue light from electronic devices can negatively impact melatonin production and delay your bedtime.
- Use light therapy: Under the guidance of a doctor, light therapy can be used to treat circadian rhythm disorders. This involves sitting in front of a light box or using a light visor/glasses, which produce bright light similar to sunlight.
- Create a dark sleep environment: Make your bedroom as dark as possible. Use blackout curtains or blinds, and wear an eye mask when sleeping.
- Use red light: If you need light at night, opt for a red night light, as red light is less disruptive to melatonin production.
By managing your light exposure and combining it with other healthy sleep habits, you can effectively reset your sleep schedule and improve your overall sleep quality.

Exercise and sleep
Exercise is an important part of resetting your sleep schedule. Regular exercise is good for your cardiovascular health and can also promote healthy sleep. Even mild physical activity, like going for a walk, can be beneficial and is a great opportunity to get some daylight exposure. Morning and afternoon exposure to daylight can help to reset your body's melatonin production, as your brain associates this light with daytime.
Exercising in the evening can also be beneficial, but it is important to finish your workout at least a couple of hours before bed. Intense exercise within an hour of bedtime may have the opposite effect, pushing your sleep schedule back and keeping you awake. This is because your body temperature and heart rate are raised during exercise, which can make it difficult to fall asleep.
If you want to exercise in the evening, it is best to do so at least 1-2 hours before bedtime. Regular exercise can help you fall asleep faster, wake up less often in the night, and even improve insomnia. Committing to physical activity can also help to promote the production of melatonin, the sleep hormone.
It is also important to be mindful of your meal times when adjusting your sleep schedule. Late meals can push back your circadian rhythm, and eating too close to bedtime can cause digestive issues that make it harder to fall asleep. Aim to finish dinner 2-3 hours before bed, and shift your meal times gradually, along with your sleep and exercise times.

Sleep schedule adjustments
Resetting your sleep schedule can take time and gradual changes are often the key to success. Here are some tips to help you adjust your sleep schedule:
Pick a bedtime and wake-up time that works for you
Choose a bedtime and wake-up time that allows you to get the amount of sleep you need. It's important to stick to this schedule every day, even on weekends. If you need to make adjustments, do so in 15 or 30-minute increments over several days. You can also focus on fixing your wake-up time first and then gradually adjust your bedtime using good sleep hygiene habits.
Plan your exposure to light
The timing of your light exposure throughout the day can greatly impact your sleep schedule. Aim to get plenty of natural light during the morning and afternoon, as this will make you less sensitive to light in the evenings. Open the curtains first thing in the morning, take a walk, or sit by a sunny window. In the evening, dim the lights and avoid electronic screens as the blue light emitted by smartphones, computers, and televisions can interfere with melatonin production.
Create a bedtime routine
Establishing a bedtime routine can help signal to your body that it's time to wind down. This could include activities such as reading, journaling, or listening to calming music.
Exercise regularly
Regular exercise can help reset your internal clock and improve your sleep quality. Aim for at least 30 minutes of moderate aerobic exercise, preferably earlier in the day.
Consider melatonin supplements
Melatonin is a hormone naturally produced by your body that helps regulate your sleep-wake cycle. If you're experiencing insomnia, jet lag, or need to adjust your sleep schedule due to work or school, melatonin supplements may help. It's recommended to take 1 to 3 milligrams two hours before bedtime. However, always consult with your doctor before taking any supplements, especially if you have other health conditions or are taking medications.
Remember, resetting your sleep schedule takes time and consistency. Be patient with yourself and maintain healthy sleep habits to achieve your desired sleep schedule.

Other sleep aids
If you're experiencing significant sleep problems, it's best to talk to your doctor about the best way to reset your sleep routine. They may recommend therapies to adjust your sleep schedule. Here are some additional strategies and therapies that can help:
- Light therapy: This treatment involves sitting in front of a high-powered lamp for a short period, usually in the morning. The bright light is intended to help reset your circadian rhythm.
- Cognitive Behavioral Therapy for Insomnia (CBT-I): This type of therapy helps to address negative thoughts and behaviours surrounding sleep, and helps structure a healthier sleep routine.
- Exercise: Regular exercise can help reset your internal clock and improve sleep quality. Aim for at least 30 minutes of moderate aerobic exercise to promote better sleep that same night.
- Bedtime routine and relaxation techniques: Creating a bedtime routine and practicing relaxation techniques can help you prepare for sleep. This might include activities such as meditation, deep breathing, or reading.
- Light exposure and timing: Plan your exposure to light, as light plays a crucial role in regulating your sleep-wake cycle. Morning light exposure can help you wake up and feel alert, while reducing light exposure in the evening can promote melatonin production and prepare your body for sleep.
- Screen time reduction: Avoid glowing electronic screens from computers, smartphones, or televisions before bed. The blue and green light from these devices can interfere with melatonin production and stimulate your brain, making it harder to fall asleep.
- Diet and nutrition: While not directly a sleep aid, consuming sufficient protein and maintaining a healthy diet can positively impact your sleep quality.
