REM sleep: Why it's important and how you can get more of it
What is REM sleep?
REM (Rapid Eye Movement) sleep is one of the most important phases of our sleep cycle and plays a central role in our mental and physical well-being. This phase accounts for about 20-25% of total sleep time and is known for rapid eye movements under closed eyelids and intense dreaming. During REM sleep, the brain and some body functions are more active than in other sleep phases. The heart beats faster, breathing becomes more irregular, and body temperature rises slightly. Despite this activity, the body is largely paralyzed during REM sleep, which is called "atonia" and prevents us from physically acting out our dreams.
Why is REM sleep important?
REM sleep is crucial for emotional and cognitive health. During this phase, the brain processes emotional experiences, organizes information, and strengthens memory. Studies show that people who get enough REM sleep are better able to learn new information and find creative solutions to problems. In addition, REM sleep helps promote emotional stability by processing emotional experiences of the day and reducing stress.
- Memory and learning: REM sleep supports the consolidation of memory content and promotes the learning of new skills. In this phase, what was learned during the day is "stored" and anchored in the brain.
- Emotional stability: REM sleep helps with emotional processing and reduces the effects of stress and anxiety. A lack of REM sleep can lead to irritability and emotional instability.
- Creativity: Many people experience creative breakthroughs or innovative thoughts during REM sleep. This phase allows the brain to make connections between seemingly unrelated ideas.
How do you get more REM sleep?
To ensure you get enough REM sleep and reap the full benefits of this important sleep phase, you can follow these tips:
- Regular sleep times: Maintain a consistent sleep schedule by going to bed and getting up at the same time every day. A regular sleep schedule supports the natural release of melatonin, the hormone that regulates the sleep-wake cycle and promotes REM sleep.
- Avoid alcohol and nicotine: These substances can interrupt REM sleep and affect the quality of sleep. While alcohol can make it easier to fall asleep, it reduces the time spent in REM sleep. Nicotine has a stimulating effect and can make it difficult to fall asleep.
- Create a relaxing sleeping environment: A quiet, dark and cool room promotes restful sleep. Invest in a comfortable mattress, cool bedding and make sure the room temperature is comfortable. An optimal sleeping environment can significantly improve sleep quality and facilitate the transition to REM sleep.
- Use a weighted blanket: Weighted blankets are known to improve sleep by providing a calming feeling of security. Studies show that weighted blankets can improve sleep quality by easing the transition to REM sleep. The consistent pressure on the body stimulates the parasympathetic nervous system, which is responsible for relaxation and recovery.
- Reduce stress: Stress and anxiety can significantly impact REM sleep. Stress management techniques such as meditation, yoga, and deep breathing before bed can help calm the mind and clear the head. Relaxation exercises before bed promote more restful sleep and increase the likelihood that you will get enough REM sleep.
Conclusion:
REM sleep is an essential phase of the sleep cycle that is vital to our emotional and cognitive well-being. By maintaining a healthy lifestyle, keeping regular sleep times, and managing stress, you can ensure you get enough REM sleep to optimally support your body and mind. Put these tips into practice to reap the full benefits of REM sleep and experience more restful nights.
