A good night's sleep is essential for our health and well-being, but many factors can disrupt our sleep schedules, from jet lag and shift work to underlying health conditions. To improve your sleep schedule, you need to reset your body clock, which regulates your body's circadian rhythms. This can be achieved through various methods, including planning your exposure to light, establishing a consistent sleep routine, practising relaxation techniques, and exercising regularly.

What You'll Learn
Plan your exposure to light
Light exposure plays a crucial role in regulating your body's circadian rhythms, which include your sleep patterns. The brain's suprachiasmatic nucleus, or master clock, receives light information from the retina and uses it to regulate the production of melatonin, the sleep-signalling hormone. When exposed to light, your brain suppresses melatonin production, making you feel awake and alert. Conversely, darkness stimulates melatonin production, promoting feelings of drowsiness.
To improve your sleep schedule, it is essential to strategically plan your exposure to light. Here are some science-backed strategies to do this effectively:
- Embrace Morning Light Exposure: Start your day by exposing yourself to natural sunlight. Open the curtains as soon as you wake up or step outside for a morning walk. This morning light exposure will signal to your brain that it's time to be awake and active, helping to reset your internal clock.
- Maximize Morning Light During Travel: If you're travelling across time zones, try to get morning light exposure as close to your "new" morning time as possible. This will help your body adjust to the new time zone more quickly. However, if you're travelling east, avoid bright light in the evening, as it may disrupt your sleep.
- Utilize Bright Light at Night for Shift Work: If you work night shifts, exposing yourself to bright light, especially blue light from electronic devices, can be beneficial. This trick can help you stay awake and alert during your shift. However, remember to minimize light exposure when it's time to sleep, as light can disrupt your body's melatonin production and make it challenging to fall asleep.
- Avoid Electronic Screens Before Bed: While electronic screens emit blue light that can stimulate alertness during the day, their glow can negatively impact your sleep if used close to bedtime. The light from computers, smartphones, and television screens can stimulate your brain for several hours, making it challenging to fall asleep. Instead, opt for calming activities that don't involve electronic screens before bed.
By planning your exposure to light, you can effectively regulate your body's production of melatonin, aligning your sleep schedule with your daily routine and improving your overall sleep quality.

Exercise daily
Exercise has been shown to improve sleep quality and reduce sleep disorders, such as insomnia. The positive effects of exercise on sleep are thought to be due to the release of endorphins, the increase in body temperature, and the promotion of melatonin production. Additionally, exercise helps to stabilize your mood and decompress the mind, which is important for transitioning to sleep.
When it comes to the type of exercise, aerobic exercise, such as swimming, biking, jogging, or walking, is particularly beneficial for improving sleep. This is because it increases the amount of slow-wave sleep or deep sleep, during which the brain and body rejuvenate. Moderate-intensity aerobic exercise is better than high-intensity exercise for improving sleep, as high-intensity exercise may interfere with sleep, especially if done close to bedtime.
The timing of exercise is also important to consider. Some people find that exercising too late in the day interferes with their sleep, while others find that they sleep better regardless of the time of day they exercise. It is recommended to finish exercising at least 1 to 2 hours before bedtime to allow the body to cool down and for endorphin levels to decrease, giving the brain time to wind down. However, the most important thing is to listen to your body and find a routine that works for you.
Overall, committing to daily exercise can help improve your sleep quality and create a positive feedback loop, where better sleep leads to more energy for working out, and working out promotes better sleep.

Avoid naps
While napping can be beneficial in certain situations, it is generally advisable to avoid naps if you're trying to improve your sleep schedule. Here's why:
Firstly, napping too close to bedtime can disrupt your nighttime sleep. Aiming to nap at least eight hours before bedtime is recommended to avoid sleep problems at night. This means that for most people, napping after 3 pm should be avoided. By taking a nap too late in the day, you risk confusing your body's internal sleep-wake cycle, making it harder to fall asleep at your desired bedtime.
Secondly, long naps can lead to grogginess and disorientation upon waking, a phenomenon known as "sleep inertia." This occurs when you wake up during deep sleep, which is more likely to happen during longer naps. To avoid sleep inertia, keep your naps short, ideally around 20 to 30 minutes. Setting an alarm can help ensure you don't nap longer than intended.
Additionally, frequent napping during the day may indicate that you are not getting sufficient sleep at night. If you find yourself relying on naps regularly, it could be a sign of sleep deprivation or poor sleep quality. In this case, it's important to assess your nighttime sleep habits and make necessary improvements to ensure you're getting the recommended amount of sleep.
Furthermore, while napping can provide a quick energy boost, it may not address the underlying causes of your daytime sleepiness. If you're experiencing excessive daytime sleepiness, it's important to evaluate your sleep hygiene, sleep environment, and overall health. Conditions such as sleep apnea, depression, or heart disease could be contributing factors.
While avoiding naps is one strategy to improve your sleep schedule, it's important to note that napping can be beneficial in certain situations, such as when you're catching up from a late night or adjusting your sleep schedule after travelling across time zones. However, if you're experiencing persistent sleep issues, it's always best to consult with a healthcare professional or a sleep specialist for personalized advice and guidance.

Establish a bedtime routine
Establishing a bedtime routine is an important step towards improving your sleep schedule. Firstly, it is important to keep a consistent sleep schedule. This means waking up at the same time every day, even on weekends or holidays. It is also important to set a bedtime that allows you to get at least 7-8 hours of sleep.
Secondly, your daily routines and behaviours, especially before bedtime, can significantly impact your sleep quality. This includes what you eat and drink, any medications you take, your level of physical activity, and how you choose to spend your evenings. For example, it is advisable to avoid caffeine and alcohol in the evening, as well as heavy meals within two hours of bedtime. Regular exercise can also promote better sleep by increasing melatonin production and aligning your circadian rhythm.
Thirdly, creating a relaxing bedtime routine is essential. This can include activities such as reading or taking a bath to help you unwind and avoid dwelling on worrisome issues. It is also important to avoid electronic screens, such as computers, smartphones, or televisions, as the blue light emitted by these devices stimulates your brain and suppresses melatonin production. Instead, dim the lights or use light-blocking window coverings to signal to your brain that it is time for sleep.
Finally, it is important to use your bed only for sleep and sex. This helps reinforce the association between your bed and sleep, making it easier to fall asleep when you go to bed. By following these steps and establishing a consistent and relaxing bedtime routine, you can significantly improve your sleep schedule and overall sleep quality.

Manage stress
Stress is a response to adverse and challenging circumstances and a response to daily life. While the right amount of stress can help us stay alert and energetic, too much can make us tense and anxious and cause sleep problems. When we are stressed, our bodies produce more cortisol, the stress hormone, which makes us feel more awake.
Identify Stressors
The first step in managing stress is to identify what is causing it. Are there certain thoughts or circumstances that are triggering your stress response? For example, thoughts about work, finances, or relationships. Once you have identified the sources of stress, you can begin to address them.
Practice Relaxation Techniques
Relaxation techniques can help to reduce stress and improve sleep. Meditation, deep breathing, and progressive muscle relaxation are all effective ways to calm the mind and body. Mindfulness meditation involves observing your thoughts and emotions without judgment, allowing them to come and go. You can also try deep breathing exercises, such as breathing down into your belly and focusing on your breath. Repeat to yourself, "Breathing in I am calm, breathing out I am coping."
Exercise
Physical activity is a great way to blow off steam and reduce stress. Exercise helps to promote melatonin production and improves sleep quality. Aim for at least 30 minutes of moderate aerobic exercise, and try to finish at least two hours before bedtime so your body temperature has time to return to normal.
Yoga and Tai Chi
Yoga and tai chi are excellent stress relief techniques that can help improve sleep. They promote healthy activity habits and improve stress management and emotional well-being.
Delegate Responsibilities
If you're feeling overwhelmed, try delegating some of your responsibilities to free up time and reduce stress. This can help you feel more relaxed and improve your sleep.
