Related Articles

Do you toss and turn throughout the night? Does it feel like waking up has become a chore? Tiredness and fatigue may be caused by not getting enough of the restorative REM and deep sleep. Let’s explore the importance of understanding sleep cycles to get the restful night’s sleep you need and deserve.

1. Exploring the Mysterious Onset of Sleep: Investigating Sleep Cycles

Sleep cycles are one of the most mysterious bodily processes we’re aware of. It’s a state of physical rest and mental relaxation, but the specifics of how it impacts us on a cellular, molecular level and why it affects us is largely unknown. So while researchers are working tirelessly to unlock the mysteries of sleep cycles, it’s also important to explore what we do know, and use that to develop potential programs and interventions that minimize the impact of inadequate sleep.

The Nature of ‘Sleep Cycles’
Sleep cycles are the 90-minute patterns that our brain-waves move through during the course of the night. While sleep usually occurs in these 90-minute cycles, additional variations occur in each stage of the cycle. During a full night’s sleep, a person will move through four or five stages, starting in lighter stages of sleep and ending with a very deep state of sleep.

High-Quality Sleep: The Benefits
When we have high quality sleep, we’re at our most efficient, alert in the morning, and ready to tackle any situation the day throws our way. We also have a higher capacity for memory and creativity, which is why getting an adequate amount of sleep is so important for a myriad of intellectual, cognitive and physical performance! Here are just a few of the benefits of getting a healthy eight hours of sleep, every night:

  • Maintain alertness and wakefulness
  • Improve short and long-term memory recall
  • Increase creativity
  • Maintain healthy cognitive function
  • Improve cognitive performance
  • Lower risks for anxiety/depression
  • Boost our immune system

Sleeping Disorders and Intervention Strategies
When we don’t get enoughSleep deprivation and sleeping disorders can cause a range of physical and mental issues, such as fatigue, difficulty focusing, lethargy, weight gain, depression, and heart disease. It’s important to talk to a doctor or sleep therapist if you experience any of these warning signs or think you may have a sleeping disorder. Various strategies can be utilized to help improve the quality of your sleep, including cognitive-behavioral therapy, relaxation training, and lifestyle changes (e.g. reducing stress, exercising regularly, minimizing caffeine/alcohol intake, and having regular sleep times).

2. Shedding Light on the Value of REM and Deep Sleep

The Vital Role of REM and Deep Sleep

Most of us know that getting a good night’s sleep is absolutely essential for our physical and Mental wellbeing. However, few of us are aware that quality sleep is not only about getting enough sleep but also what type of sleep we’re getting. We don’t just have one type of sleep; different sleep cycles and states of consciousness have a remarkable effect on our alertness, cognitive functions, and overall wellbeing.

Two key sleep states we experience are integral for keeping us balanced and healthy – Rapid Eye Movement (REM) sleep, and Deep Sleep.

  • Rapid Eye Movement (REM) sleep is the lighter stages of sleep. In REM, our eyes flicker rapidly, our bodies dip in and out of paralysis, and we dream. During this stage, our brains process what we learned during the day and create memories.
  • Deep Sleep is much more restful, lasting longer than REM. In this stage, our body produces growth hormones to repair and restore, this is when our physical and emotional health gain the most benefit from sleep.

REM and Deep Sleep are both important for maintaining good mental and physical health, but with adulthood, the amount of time spent in these states decreases. Poor sleep affects our ability to focus, learn, remember, and make decisions. It also affects mood, energy levels, and even our immune system.

Understanding the importance of REM and Deep Sleep can help us make adjustments to our lifestyle and diet that will benefit our overall wellbeing. Ensuring we have the right balance of REM and Deep Sleep can help us feel energised, focused and ready to take on the day.

Sleep is one of the most neglected aspects of wellbeing. Many people don’t realise the vital role sleep plays in their overall health, but the reality is that inadequate or disrupted sleep can lead to a host of issues.

You may know that your body follows certain sleep cycles, but do you understand the link between these cycles and your health? Here, we explore what happens with each stage of sleep and why it’s so essential for optimal wellbeing.

The Non-REM Sleep Cycle

Non-REM sleep, or NREM, is the longest sleep phase. It typically makes up 75-80% of total sleep time in an adult. This cycle is made up of four distinct phases – N1, N2, N3, and N3 – and is responsible for mind restoration and body repair. During this stage, hormones such as melatonin, cortisol, and growth hormone are released.

  • N1: During N1, your muscles relax and your body adjusts to sleep. This phase is the lightest form of sleep and can be easily disrupted.
  • N2: N2 is the most common phase of sleep and your body is mostly still and inactive. Your heart rate and temperature drop, and hormones such as prolactin are released.
  • N3: During this deep cycle of sleep, growth hormones are released, and your body repairs and rebuilds
  • N4: N4 is the deepest cycle of non-REM sleep. During this stage, your heart rate further decreases, breathing slows, and your body repairs itself from physical exertion.

REM Sleep

During the REM sleep cycle, your body enters a dream state and your brain activity increases. This is where the most vivid dreams occur. It typically makes up 20-25% of your total sleep time each night, lasting for around 90 minutes.

REM sleep is vital for mental and emotional health. During this stage, your neural pathways, which are essential for memory consolidation and learning, are strengthened. This helps your brain to store and retrieve information.

REM sleep is also essential for creativity, problem-solving, and even generating creative new ideas. This stage of sleep is essential for dreaming and consolidating memories.

4. Strategies for Achieving Better Quality Sleep

Achieving better quality sleep is an important factor in feeling rejuvenated and overall better health. Here are some strategies to immediately make a difference in the quality and quantity of your sleep.

  • Create An Ideal Sleeping Environment
    Ensure your bedroom is cool, dark, and quiet. Invest in a comfortable mattress and bedding that help you relax and eliminate any outside noises.
  • Set A Sleep Schedule
    Going to bed and waking up at the same time each day will help keep your body’s natural internal clock in check. This will also help you develop a steady night-time routine.
  • Avoid Stimulants
    That late night cup of coffee may be tempting but it won’t help you reach peaceful rest. Limit or avoid caffeine, nicotine, and alcohol for several hours before bed.
  • Relax Before Bed
    Before getting into bed, take some time to wind down. One of the best ways to do this is to practice some breathing relaxation techniques or meditation. Other calming activities such as reading a book or taking a hot bath can also be beneficial.
  • Exercise
    Regular exercise can help you sleep better. Going for a 30 minute walk during the day will get your body used to a regular sleep schedule and you’ll feel more tired at night.
  • Limit Naps
    Avoiding naps during the day can reduce your sleepiness at night and give you a better quality sleep. If you feel tired during the day, try drinking an energizing cup of tea instead of laying down for a nap.

Creating good sleep hygiene is the best way to make sure you get a good night’s sleep. Implementing these strategies as a part of your routine will leave you feeling refreshed and rested with no need for unnecessary sleeping aids or medications.

Good sleep is essential to remaining alert and having enough energy to tackle even life’s most difficult challenges. With a better understanding of REM and deep sleep, you can get the quality rest you need to remain sharp and motivated each day. Reclaim your nights and get the most out of your days by exploring what kind of sleep you need to feel at your best. Sweet dreams!
