Getting a good night's rest is essential for our health and well-being. Sleep is not just a passive activity; it is a complex process that involves multiple stages, one of which is REM sleep. REM sleep, or rapid eye movement sleep, is characterised by increased brain activity, eye movement, heart rate, blood pressure, and breathing. It is during this stage that most of our dreams occur. REM sleep is crucial for brain development, memory, learning, and emotional regulation. However, various factors can disrupt this stage of sleep, leading to negative consequences for our health. So, how can we achieve better REM sleep?

What You'll Learn
Limit caffeine, nicotine, and alcohol
Caffeine, nicotine, and alcohol are stimulants that can interfere with your sleep, particularly REM sleep. Consuming caffeine and nicotine late in the day prolongs sleep latency, reducing the time available for REM sleep. Similarly, while alcohol may help you fall asleep, it significantly suppresses REM sleep during the second half of the night. Chronic alcohol use worsens this effect.
To achieve better REM sleep, it is advisable to limit your consumption of these substances. Try not to drink caffeine or smoke cigarettes later in the day. If you drink alcohol, avoid doing so before bed.
Additionally, maintaining a consistent sleep schedule is crucial for optimizing REM sleep. Aim to go to bed and wake up at the same time every day, even on weekends. This helps regulate your body's circadian rhythm, promoting healthier sleep patterns and enhancing the quality of your REM sleep.
If you are struggling with sleep despite limiting caffeine, nicotine, and alcohol, consider consulting a healthcare professional. They can provide guidance and help you identify any underlying factors that may be disrupting your sleep.

Maintain a sleep schedule
Maintaining a consistent sleep schedule is crucial for achieving better REM sleep. Here are some detailed tips to help you establish and stick to a sleep schedule:
Set a regular bedtime and wake-up time:
Commit to a specific bedtime and wake-up time that you can follow consistently. This helps regulate your body's sleep-wake cycle, making it easier to fall asleep at night and wake up in the morning. Consistency is key, so stick to your chosen schedule even on weekends and during vacations.
Avoid sleeping in or napping after a night of poor sleep:
If you have trouble sleeping one night, resist the temptation to sleep in or take a nap the next day. While you may feel more tired, maintaining your regular sleep schedule will help you sleep better the following night. Disrupting your routine can negatively impact your sleep patterns.
Create a relaxing bedtime routine:
Establish a calming pre-sleep routine to help you wind down and prepare for sleep. This can include activities such as reading, listening to soothing music, or practising relaxation techniques like deep breathing or meditation. Start your bedtime routine at the same time each night to signal to your body that it's time to prepare for sleep.
Avoid stimulants and alcohol:
Limit your consumption of caffeine, nicotine, and alcohol, especially later in the day. These substances can interfere with your sleep. Caffeine and nicotine are stimulants that can make it harder to fall asleep and reduce your overall sleep time, including the crucial REM sleep phase. While alcohol may initially make you feel sleepy, it suppresses REM sleep during the latter half of the night, leading to disrupted sleep.
Maintain a consistent sleep environment:
Keep your sleep environment comfortable, dark, quiet, and at a neutral temperature. Exposure to noise, artificial light, or extreme temperatures can cause frequent awakenings, disrupting your sleep cycles and reducing the duration of your REM sleep.
Address sleep disorders:
If you suspect you have a sleep disorder, such as insomnia or sleep apnea, seek professional help. Treating the underlying condition can significantly improve your sleep quality and restore normal proportions of REM sleep.

Avoid screens before bed
Avoiding screens before bed is a crucial step in achieving better REM sleep. The light from screens, such as TVs, computers, phones, and other electronic devices, can interfere with your sleep and disrupt your REM cycles. A Norwegian study found that one hour of screen time before bedtime resulted in a 59% higher risk of insomnia and 24 minutes less sleep. This is because the light from screens can delay the release of melatonin, the hormone that regulates sleep.
To avoid the negative impacts of screen time, it is recommended to limit your exposure to screens at least one to two hours before your bedtime. This will give your mind time to relax and wind down, making it easier to fall asleep. Instead of using electronic devices, you can engage in relaxing activities such as reading, knitting, or listening to soothing music.
If you must use screens before bed, there are a few strategies to minimize their impact. You can enable night mode or blue light filters on your devices, which reduce the amount of blue light emitted and may help reduce the disruption to your sleep. Additionally, lowering the brightness of your screens can also help reduce the stimulating effects of the light.
It is important to prioritize a consistent sleep schedule, as disruptions to your sleep-wake cycle can confuse your body's internal clock and negatively impact your REM sleep. By avoiding screens before bed and maintaining a regular sleep schedule, you can improve your chances of achieving better REM sleep and overall sleep quality.

Exercise and spend time outdoors
Exercise and spending time outdoors are two important components of achieving better REM sleep. Firstly, exercising daily is crucial. Engaging in physical activity helps tire your body, making it easier to fall asleep and improving your overall sleep quality. Aim for a mix of aerobic exercise, such as walking, running, or swimming, and strength training, which can include bodyweight exercises or weightlifting.
However, it's important to time your workouts appropriately. Morning or afternoon workouts are ideal because exercising too close to bedtime may make it harder to fall asleep due to heightened alertness and an elevated body temperature. Try to finish your workout at least three hours before your bedtime to give your body time to relax and wind down.
Secondly, spending time outdoors is beneficial for your sleep. Natural sunlight exposure is a powerful regulator of your body's internal clock, known as the circadian rhythm. This rhythm plays a crucial role in determining when you feel alert and when you feel sleepy. By spending time outdoors, especially in the morning, you can reinforce this rhythm, making it easier to fall asleep and wake up at consistent times.
Additionally, when you're outdoors, you're often exposed to fresh air and natural environments, which can be calming and help reduce stress levels. Lower stress can improve your sleep quality and duration, including REM sleep. So, consider taking a walk in the park, practicing outdoor meditation, or simply sitting and reading in your backyard.
In summary, exercising and spending time outdoors are integral parts of achieving better REM sleep. They work synergistically to improve your sleep quality and duration, helping you feel more rested and energized each day.

Treat underlying mental health issues
REM sleep, or rapid eye movement sleep, is a sleep stage characterised by rapid eye movement and is associated with dreaming. It is important for brain health and function, and plays a role in memory, problem-solving, mood regulation, and brain development.
Disturbances in REM sleep have been linked to certain mental health conditions such as schizophrenia, bipolar disorder, and major depressive disorder. If you are experiencing sleep problems due to an underlying mental health issue, it is important to seek professional help. Here are some ways to treat underlying mental health issues and improve your REM sleep:
Consult a Healthcare Professional
If you suspect that your mental health is affecting your sleep, reach out to a healthcare provider or a sleep specialist. They can help identify any underlying concerns and work with you to develop a personalised treatment plan. Sleep issues may be due to an undiagnosed medical condition or sleep disorder, such as REM sleep behaviour disorder (RBD), which a doctor can help treat.
Medication and Therapy
Certain medications, such as antidepressants and antipsychotics, can interfere with REM sleep. If you are taking medication that is affecting your sleep, consult your doctor about alternative options or adjusting your dosage. Cognitive-behavioural therapy (CBT) is also recommended alongside treating the underlying psychiatric condition.
Create a Conducive Sleep Environment
Your sleep environment plays a crucial role in the quality of your rest, including your REM sleep. Ensure your bedroom is free from bright lights, extreme temperatures, and electronic distractions such as televisions or computers. If you suffer from RBD, take extra precautions to create a safe sleeping environment by removing sharp objects and heavy items from your bedside and considering sleeping in a different room if necessary.
Maintain a Consistent Sleep Schedule
Sticking to a regular sleep schedule can boost both your physical and mental health, improving the quality of your REM sleep. Aim to go to bed and wake up at the same time each day. This habit may take some time to establish, but it will become easier over time as your body adjusts to the routine.
Address Stress and Anxiety
Stress, anxiety, and distressing nightmares can disrupt your REM sleep. If you feel that your mental health is impacting your sleep quality, consider reaching out to a healthcare provider to discuss treatment options and strategies for managing stress and anxiety. Relaxing activities before bed, such as meditation, reading, or listening to soothing music, can also help prepare your mind and body for sleep.

Frequently asked questions
To increase your REM sleep, you need to get more sleep overall. Try to get between 90 and 120 minutes of REM sleep per night. Create a relaxing bedtime routine and stick to a sleep schedule, even on weekends. Avoid nicotine, caffeine, and alcohol, and spend some time outside in natural sunlight every day.
REM sleep is important for your health and well-being. It supports memory, learning, and emotional resilience, and helps regulate your emotions. It also promotes physical repair, supporting immune function and cellular regeneration.
During REM sleep, your heart rate, blood pressure, brain activity, and breathing increase. Your eyes move rapidly, and your muscles become temporarily unable to move, preventing you from acting out your dreams. Your brain is also active during this stage, processing emotions and memories.
Both REM and non-REM sleep are important for different reasons. While REM sleep is important for learning and memory, non-REM sleep is when your body repairs and regenerates tissues. During non-REM sleep, your heart rate and body temperature decrease, and you experience deeper sleep.
