What Are Delta Waves? Here Are 5 Great Benefits of Deep Sleep.

What are delta waves? A delta wave is a type of brain wave commonly associated with deep sleep. Ideally, about 20% of your sleep should be deep sleep, and proper rest confers many great benefits, including improved learning, mood, cell regeneration, immune function, and energy.

There is no shortage of experts touting the benefits of a good night’s sleep. Many would argue that it is foundational for good health. There are four stages of sleep, each conferring different benefits. The most restorative stage of the sleep cycle is stage 3, better known as deep sleep, which is when our brains produce delta waves.

Types of brain waves and their benefits

What are delta waves? They are one of five different types of brain waves: gamma, beta, alpha, theta, and delta. The fastest brain waves are gamma waves, produced when you are in a state of peak concentration and simultaneously processing information from different brain areas.

The next fastest and more commonly utilized are beta waves. Beta waves are characteristic of an intensely aroused and engaged mind; when engaging in an intellectually stimulating conversation, reading a book, teaching a class, or giving a presentation, you are using beta waves.

When you complete a task and immediately reflect on it (you finish giving that presentation and sit back down again), now you are utilizing alpha waves. They are the brain waves of a relaxed and stable mind, which might occur while meditating.

Next are the brain waves we associate with mindlessness, theta waves. That is not to say that when you are utilizing theta waves, you are not being productive; in fact, these brain waves are associated with creativity and generating ideas. They occur when you are engaged in a task that is repetitive and straightforward enough that you can mentally disengage from it, allowing your mind to wander. Theta waves are the brain waves of daydreaming.

Finally, there are delta waves. What is delta waves’ function in the brain? They are the brain waves of deep, restful sleep. The kind of sleep that creates delta waves can provide various benefits to the brain and body.

What are delta waves and what are their benefits?

Improved learning

Most people might not feel particularly sharp after a poor night of sleep. This is because one of the more significant benefits of deep sleep is its effect on cognitive functioning – almost every facet of brain functioning can be correlated to sleep quality in some way.

Studies have shown that getting more deep sleep, or the sleep that produces delta waves, improves memory, motor skills, and the ability to learn and utilize language.

Further studies found that more deep sleep may aid in the cognitive function of those with Parkinson’s disease and may help slow the development of dementia. Conversely, lack of deep sleep or deep sleep disruption increases cerebrospinal fluid amyloid-β, which may cause Alzheimer’s disease.

Improved mood

There’s something to be said for waking up on the wrong side of the bed. Inadequate sleep and poor mood are directly linked, and that’s backed by science. Not only does a lack of deep sleep lead to irritability, stress, anxiety, and depression, but it can also affect our empathy. Poor quality sleep has been shown to disrupt the process of consolidating and processing memories and can make us less empathetic.

Improved immune function

When we get sick, one piece of advice doctors always give is to get some rest. Deep sleep leads to an improved immune system, especially if you’re feeling under the weather. Research supports this link between sleep and the immune system.

Deep sleep helps regulate certain cytokines and natural killer cells, resulting in a stronger immune system and helping the body fight against different types of cancer, viral infections, and chronic autoimmune diseases. Conversely, a lack of deep sleep leaves you more susceptible to infection by decreasing the body’s response to vaccines.

Much like cognition, our energy levels suffer after a poor night of rest. Delta waves from deep sleep are specifically responsible for recharging our energy levels for the next day; this is because they play a critical role in glucose metabolism or the process of generating ATP, which provides fuel for the brain.

Cell regeneration

Consistent deep sleep can help keep you looking and feeling young for many reasons, mainly its effect on the cells. Delta waves trigger the release of human growth hormone (HGH), which helps maintain tissues and organs, promotes cell growth, and aids metabolism.

In addition, there is evidence that deep sleep may also increase the release of dehydroepiandrosterone (DHEA), a hormone that acts as a precursor to male and female sex hormones. HGH and DHEA decrease as we age, and delta waves can help slow this process and increase our quality of life.

Increasing delta waves

Several things can be done to improve sleep quality and increase the production of delta brain waves. An example is the use of supplements to improve sleep. Certain nutrient deficiencies can affect sleep quality, particularly a lack of magnesium and vitamin D; supplementing these nutrients can help improve sleep.
BrainLuxury has a supplement called DELTA which includes both of these ingredients as well as others to induce more deep sleep. For example, DELTA contains the amino acids tryptophan and glycine.

Tryptophan can help you fall asleep faster, and glycine helps you get into a deeper sleep. DELTA also features fatty acids that studies suggest aid in sleep quality. It is rare to find this particular blend of ingredients in many sleep aids available over the counter.

Various methods and lifestyle adjustments can be used to help get more deep sleep. Getting more exercise, limiting exposure to blue light emission from phones, computers, and TV screens, and eating a nutritious diet that limits caffeine and alcohol close to bedtime are just a few. Don’t sleep on these antidotes to a poor night’s rest. Your body will thank you for it.

Vitamin D help to improve the sleep system.
