Deep Sleep: Benefits and Tips on How To Increase Deep Sleep

Deep sleep, one of the vital stages of the sleep cycle, is crucial for supporting both physical and mental well-being. It helps to support memory consolidation, learning, and repairing essential tissues in the body. So, how can you increase it to maximize the full benefits?

In this article, we’ll explore the importance of deep sleep and provide evidence-based strategies to improve your sleep quality.

Understanding Deep Sleep

When we go to sleep at night, our bodies will cycle through 4 different sleep stages— Non-Rapid Eye Movement (NREM) and Rapid Eye Movement (REM) sleep stages in the sleep cycle. Deep sleep, often referred to as slow-wave sleep, is a pivotal stage within the non-REM sleep cycle.

Deep sleep occurs during the first half of the night and is characterized by the presence of slow delta waves in brain activity. This stage is indispensable for both physical and mental rejuvenation, strengthening the immune system, and promoting optimal brain function and memory consolidation

Adults typically need different amounts of deep sleep, but the lack of it is associated with numerous health issues, including a higher risk of heart disease and Alzheimer’s disease [1].

During deep sleep, the brain waves slow down significantly, allowing for the consolidation of new information and the repair of the body and brain.

How Much Deep Sleep Do We Need?

Research suggests that adults should aim for at least 90 minutes of deep sleep per night, although this can vary [2]. Those who don’t get enough of it may experience disruptions in physical and mental health, as well as impaired cognitive function.

Benefits of Deep Sleep

As we know, the deep sleep stage plays a crucial role in ensuring that our brain gets proper rest and recovery. Getting enough of it can have great benefits on our health such as:

Release of growth hormones and repair of tissues

Deep sleep is important for releasing growth hormones and repairing tissues in your body. During this stage, your body releases growth hormone, which helps promote muscle, bone, and tissue repair. This repair process is crucial for overall health and recovery from injuries or intense physical activities.

Cognitive function and memory enhancement

Getting enough deep sleep can have significant benefits for your cognitive function and memory enhancement. It is a vital part of your sleep-wake cycle. It helps with memory consolidation as well as memory formation for emotional and non-emotional tasks [3]. You may experience cognitive function, memory, and even language learning difficulties without enough deep sleep.

So, prioritizing deep sleep can positively impact your overall brain health and performance.

Strengthens immune system

Another benefit of getting a good amount of deep sleep is that it helps to strengthen your immune system and prevents you from falling sick so easily. When we fall asleep at night, our bodies produce a protein called cytokine. This protein helps our body to fight infection and inflammation as a normal immune response [4].

Allowing your body to rest can help to build resilience and adapt to these challenging times.

Factors Affecting Deep Sleep

Factors that can impact the duration and quality of deep sleep are your sleep environment, lifestyle choices, and certain medical conditions. However, some factors can disrupt your deep sleep patterns.

• An uncomfortable sleep environment, like a noisy or bright room, can interfere with deep sleep. It’s essential to create a calm and quiet space for sleeping to promote better sleep.
• Lifestyle choices also plays a role. Consuming caffeine or alcohol before bed, having irregular sleep schedules, and spending too much time on screens can all negatively affect the amount of deep sleep you get.
• Certain medical conditions, such as sleep apnea or insomnia, can also lead to a lack of deep sleep. If you suspect a medical condition affecting your sleep, it’s important to seek professional help and get a proper diagnosis.

Addressing these factors is crucial for ensuring a good night’s rest and maximizing the benefits of deep sleep for your health and well-being.

Sleep Disorders Associated With Deep Sleep

Sleep disorders can disrupt deep sleep and cause various disturbances. These disorders include sleep apnea, insomnia, restless leg syndrome, sleepwalking, and night terrors. Certain medications and substances can also affect deep sleep.

Here are some ways these sleep disorders can impact your restful state:

• Sleep apnea interrupts your breathing during sleep, leading to frequent awakenings and reduced deep sleep.
• Insomnia, difficulty falling asleep or staying asleep, can result in reduced deep sleep.
• Restless leg syndrome causes uncomfortable sensations in the legs, leading to movement and disruption of deep sleep.
• Sleepwalking and night terrors, a type of parasomnia, can occur during deep sleep and cause confusion and fear.

If you suspect you have a sleep disorder, it’s essential to consult a healthcare professional for diagnosis and treatment options. They can help identify your specific sleep disorder and provide appropriate recommendations to improve your sleep quality.

Effects of Insufficient Deep Sleep

Insufficient deep sleep can significantly impact your overall health and well-being. Deep sleep is important for memory consolidation, so not getting enough of it can affect your ability to remember and recall information. It can also weaken your immune system, making you more susceptible to infections. Moreover, disruptions in deep sleep have been linked to neurological conditions like Alzheimer’s and Parkinson’s disease.

In addition to these effects, sleep deprivation can lead to hormonal changes that can affect your appetite. This can potentially result in weight gain and increase your risk of developing insulin resistance, type 2 diabetes, and heart disease.

How Do I Get Better Deep Sleep?

Many of us often wonder how to increase our deep sleep. We’ve created a video on “How to Get More Deep Sleep” in collaboration with Dr. June Seliber Klein, the Chief Medical Officer at Ognomy.

It’s important to note that both the duration and quality of deep sleep are crucial for overall health and well-being. In the next few sections, we’ll share tips on how to improve your deep sleep.

Prioritize getting enough sleep

Ensuring you’re getting enough sleep each night is essential. Most adults require around 7-9 hours of quality sleep to function optimally. Establishing a consistent sleep schedule can significantly help. Try going to bed and waking up at the same time every day, including weekends. This regularity can regulate your body’s internal clock, making it easier to fall asleep and wake up feeling refreshed.

Create a relaxing bedtime routine

Creating a relaxing bedtime routine can signal your body that it’s time to wind down. Avoid engaging in stimulating activities or using electronics before bed, as these can disrupt your ability to fall asleep.

Instead, opt for calming activities such as reading a book, taking a warm bath, or practicing relaxation techniques like deep breathing or meditation. These practices can help calm your mind and prepare your body for a restful sleep.

Conclusion

Deep sleep is a crucial phase of our slumber that offers incredible benefits for our physical and mental well-being. It is pivotal in promoting growth, repairing the body, and enhancing cognitive function and memory retention. However, factors such as stress, insomnia, and aging can affect the quality and duration of deep sleep.
