Enhancing Rem Sleep: Strategies For Deeper Rest

Getting a good night's sleep is essential for our health and well-being, and one of the most important stages of sleep is REM sleep. REM sleep, or rapid eye movement sleep, is when we get our most mentally restorative sleep, and it is vital for memory consolidation, brain development, and mood regulation. While we can't control how long we spend in each stage of sleep, there are several things we can do to increase the amount of REM sleep we get. Here are some tips to improve the quality of your sleep and get more REM sleep:

- Develop and maintain a consistent sleep schedule, even on weekends.

- Treat any underlying sleep disorders that may be disrupting your REM sleep.

- Avoid alcohol, caffeine, and tobacco, especially close to bedtime, as these substances can interfere with your sleep.

- Adopt good sleep hygiene practices, such as exercising regularly, maintaining a cool and dark bedroom, and establishing a relaxing bedtime routine.

- Manage stress, avoid late meals, and limit screen time before bed.

- Try natural remedies such as blue-light blocking glasses, reading before bed, or using a sleep mask and earplugs.

Develop a sleep schedule

Developing a sleep schedule is one of the most important things you can do to promote REM sleep. This means going to bed and waking up at the same time every day, even on weekends. This primes your body for sleep and waking, and disrupting this balance by keeping irregular sleep-wake times may confuse your body and interfere with REM sleep regulation.

• Consistency is key: Try to go to bed and wake up at the same time each day. This helps your body to function more efficiently, and an analysis of sleep data from 25,000 people showed a substantial rise in nightly REM sleep duration as sleep consistency increased.
• Understand your sleep need: Everyone's sleep need is unique, and it's determined by genetics. The average sleep need is around 8 hours and 40 minutes, but some people may need 9 hours or more. Use a sleep app or tracker to help you work out your individual sleep need and aim for this number each night.
• Consider sleep efficiency: Take into account the time it takes for you to fall asleep (sleep latency) and the time you wake up during the night (sleep fragmentation). Add 30 minutes to an hour to your sleep need and spend this long in bed to ensure you get enough sleep and REM sleep.
• Maintain a consistent sleep pattern: Find a sleep schedule that works for you and stick to it, even on weekends or days off. This will help regulate your body's internal clock and improve your sleep quality.
• Sync with your circadian rhythm: Your circadian rhythm is your body's internal biological clock, which dictates energy levels, hormone production, and body temperature. Try to go to bed and wake up at times that align with your natural circadian rhythm. For example, if you're a night owl, honour that instead of forcing yourself to be a morning person.
• Create a bedtime routine: Establish a relaxing bedtime routine with soothing activities such as reading, taking a warm bath, doing yoga, journaling, or listening to music. This will help you unwind and reduce stress before bed, making it easier to fall asleep.

Avoid alcohol, caffeine, and tobacco

Alcohol, caffeine, and tobacco are stimulants that can interfere with your sleep and reduce the amount of REM sleep you get. It is best to avoid these substances altogether, but if that is not possible, do not consume them in the late afternoon or evening.

Alcohol negatively affects your sleep, particularly REM sleep. While it may make you feel sleepy at first, it interferes with your sleep cycle, causing you to spend less time in the REM stage. Drinking alcohol before bed can delay your entry into the REM stage, and you may miss out on the crucial first episode of REM sleep. This results in a higher proportion of light sleep and a decrease in slow-wave sleep, which is vital for proper rest.

Caffeine and tobacco can also disrupt your sleep patterns and normal progression through the various sleep stages. Consuming caffeine and tobacco products in the evening or close to your desired bedtime can significantly impact your sleep quality. It is advisable to cut down on these substances and refrain from having them within several hours of your bedtime.

Additionally, it is important to maintain good sleep hygiene. This includes avoiding bright lights, creating a comfortable temperature in your bedroom, and refraining from watching television or working on computers before bed. Establishing a relaxing bedtime routine and engaging in soothing activities, such as reading or listening to calming music, can also enhance your sleep quality.

Exercise regularly

Exercising regularly is an important part of improving your sleep quality and, in turn, increasing your REM sleep. However, it's important to avoid exercising too close to bedtime, as this may interfere with your sleep.

Exercising during the day can help regulate your body's temperature control, which is an important part of falling asleep. When you exercise, your body temperature rises, and then it takes some time for it to drop back down. This process can help signal to your body that it's time to sleep, but only if you time your workout correctly.

It's recommended that you finish your workout at least three hours before bedtime. This will give your body enough time to wind down and prepare for sleep. If you exercise too close to bedtime, your body temperature might still be too high, making it difficult to fall asleep.

Exercising in the morning or early afternoon is ideal. This way, you can take advantage of the boost in body temperature to energise your day, and by the time you're ready for bed, your body will be ready to cool down and fall asleep.

It's also important to note that the type of exercise you do may impact your sleep. More intense workouts, like high-intensity interval training (HIIT), can be more stimulating and may disrupt your sleep if done too close to bedtime. Opt for more moderate-intensity exercises, such as brisk walking, swimming, or yoga, especially in the evenings.

Additionally, if you're just starting to incorporate exercise into your routine, start slowly and gradually increase the intensity and duration of your workouts. This will help your body adjust and reduce the risk of injury.

Remember, the goal is to improve your overall sleep quality, which will, in turn, increase your REM sleep. So, make sure to listen to your body and find an exercise routine that works best for you.

Create a suitable sleep environment

Creating a suitable sleep environment is crucial for promoting more REM sleep. Here are some detailed tips to help you achieve this:

Maintain a Cool, Dark, and Quiet Bedroom

Keep your bedroom well-ventilated and ensure a comfortable temperature. Aim for a slightly cooler temperature, as a dark and cool environment can promote better sleep. Set your thermostat to around 65 to 68 degrees Fahrenheit. If necessary, use a fan or air conditioning to maintain a pleasant temperature. Additionally, ensure your bedroom is quiet by minimising external noises. Consider using earplugs or a white noise machine to create a peaceful and serene atmosphere.

Avoid Bright Lights

Minimise exposure to bright lights, especially before bedtime. Avoid using electronic devices with screens, such as smartphones, tablets, or laptops, for at least 90 minutes before going to bed. The blue light emitted by these devices can interfere with your sleep. Instead, opt for activities that promote relaxation, such as reading a book, listening to soothing music, or taking a warm bath. If you need to use electronic devices, consider wearing blue-light blocking glasses to reduce the impact on your sleep.

Establish a Regular Bedtime Routine

Develop a soothing and consistent bedtime routine. Engage in activities that help you unwind and relax before going to bed. This could include reading, practising yoga, journaling, or listening to calming music. A warm bath can also be a great way to relax your body and mind. By establishing a bedtime routine, you signal to your body that it's time to prepare for sleep, making it easier to fall asleep and improve your overall sleep quality.

Keep Gadgets and Screens Out of the Bedroom

It is essential to create a tech-free zone in your bedroom. Avoid using laptops, tablets, or smartphones in bed. The blue light and mental stimulation from these devices can disrupt your sleep. Instead, charge your devices in another room and opt for more relaxing activities that promote better sleep. If you must use your gadgets before bed, try to finish at least an hour before your bedtime to give your mind time to unwind.

Maintain a Consistent Sleep Schedule

Go to bed and wake up at the same time every day, even on weekends. Maintaining a consistent sleep schedule helps regulate your body's internal clock, making it easier to fall asleep and improving your overall sleep quality. This consistency in your sleep and wake times will help your body establish a natural rhythm, making it more likely for you to get sufficient REM sleep.

Adopt sleep hygiene habits

Adopting good sleep hygiene habits can help improve your sleep quality and, consequently, the amount of REM sleep you get. Here are some tips to improve your sleep hygiene:

Maintain a Sleep Schedule

It is important to go to bed and wake up at the same time every day, even on weekends. Keeping a consistent sleep schedule helps regulate your body's internal clock, or circadian rhythm, which plays a crucial role in promoting REM sleep.

Create a Relaxing Bedroom Environment

Make your bedroom a peaceful and inviting space for sleep. Keep the room cool, dark, and quiet. Set the thermostat to a comfortable temperature, between 65 to 68 degrees Fahrenheit. Use blackout curtains or blinds to block out any unwanted light, and consider wearing an eye mask and earplugs to enhance your sleep environment.

Establish a Bedtime Routine

Develop a calming pre-sleep routine to signal to your body that it's time to wind down. This could include reading a book, listening to soothing music, practising yoga, journaling, or taking a warm bath. Engaging in relaxing activities before bed can help reduce stress and anxiety, making it easier to fall asleep.

Avoid Stimulants and Screens

Refrain from consuming caffeine, alcohol, or tobacco/nicotine close to bedtime. These substances can interfere with your sleep and disrupt your normal sleep stages. It is best to avoid them entirely in the late afternoon or evening. Additionally, limit your exposure to screens from electronic devices before bed, as the blue light emitted by these devices can negatively impact your sleep.

Exercise Regularly

Engaging in regular physical activity during the day can improve your sleep quality. Aim for at least 30 minutes of exercise daily, but make sure to finish your workout several hours before bedtime to give your body time to relax and wind down before sleep.
