Best Supplements for Slow-Wave Sleep – Buying Guide

Following is a guide designed to help you understand the needs and demands of a sleep-deprived body and mind and get you better equipped with relevant information so that you can make an informed decision when you are buying the best supplements for slow-wave sleep.

What is Slow Wave Sleep

Slow-wave sleep, also known as delta sleep, is the final stage of sleep. This is where you are at your mind and your body is at its most relaxed. The muscles are relaxed, so is your breathing. Once you have entered this stage, there are fewer chances of waking up disruptively and getting disturbed in your sleep. 

This is why this stage of sleep is so important. This stage has been studied to see what makes it the deepest sleep stage. Sleep specialists have highlighted the all-time slow-wave brain activity pattern known as the delta waves. 

What makes these waves so special are not just the slow waves, but slow waves with high altitude and low frequency. These sleeping patterns can be termed NREM or SWS patterns. Now, let’s dissect what these waves indicate is happening in your body when you are in the 3rd sleep stage. 

The first segment of the delta wave is termed the down wave or the inhibition state. In this stage, the neurons are slowly silencing themselves to let the body calm down and soothe so that you can get that deep sleep. The second segment of this delta is a small excitation period where neurons palpitate for a small period. 

Why is Slow Wave Sleep Important

What makes this stage so special is the purpose it plays in the overall brain health and memory power. Well, that’s true. Science has shown that this stage of sleep plays a crucial role in body recovery, cell regeneration, and growth. 

Though almost every healthy sleeper experiences the SWS, the duration of the cycle reduces with time. The regular and healthy duration of this slow-wave sleep cycle is around 20 to 40 minutes. With the right dietary routine and sleep supplements, you can increase the duration of slow-wave sleep.

Benefits of Slow Wave Supplements

The main purpose of sleep supplements is that they’ll help you fall asleep quicker and save you from the misery of tossing and turning all night. Sleep supplements not only help to relax your body and mind so that you can fall asleep but also help to manage your sleep routine and cycle. 

Another benefit of sleeping aids is that they help to improve the quality of sleep. A lot of the time when people with sleep issues do fall asleep, it is always a restless slumber which is why a lot of the time people wake up even more tired than they were before. 

The added nutrients such as melatonin and valerian will help you stay asleep and enter the slow-wave sleep cycle for proper and undisturbed sleep. For a lot of individuals, sleeping issues stem from unchecked anxiety levels and added stress. 

These two components don’t let your brain rest at night and keep you up thinking about all sorts of stuff. This is why a lot of the sleeping aids you’ll see will have 1 or 2 anti-anxiety nutrients. 

Micronutrients to Look for In Slow Wave Sleep Supplements

Micronutrients are all the ingredients present in sleep supplements. General enhancers are found in almost all sleep supplements and are backed by scientific and trial studies as well. 

These nutrients improve the overall health of your brain so that you can fall asleep easily. Moreover, they are key enhancers that will directly affect and improve the slow-wave sleep phase for a deep slumber. 

  • Glycine

Glycine is a very important amino acid that mainly has functions in the nervous system. Glycine has been seen to improve the quality of sleep and reduce the after-effects of sleep disruption. Most of the scientific proof of glycine’s performance in aiding sleep routine comes from placebo-based trials. 

All of them have shown remarkable results that are affirmative regarding glycine’s contribution to good sleep. According to research, our body temperature drops when we are sleeping or when we are getting sleepy. 

This is why sleeping in a lower temperature setting is encouraged for people suffering from disrupted sleep. Glycine has been seen to help lower the body temperature to hint the body that it’s time to sleep.  

  • 5-HTP

5-HTP is an indirect supporter of a good sleep schedule and regime. 5-HTP is a by-product compound already found within the body. It is produced when amino acid tryptophan is broken down in the body. 

What this by-product does is that it gets utilized in the production of more and more serotonin. Serotonin is a hormone that manages and controls the sleep-wake cycle. Serotonin helps in the making of melatonin, and this is where the magic begins. 

5-HTP helps the body to fall asleep quicker and reduces stress and anxiety symptoms. Lack of stress molecules helps the body relax which in turn helps the body to drift into quick slumber rather easily.

  • Vitamin E

Vitamin E has been seen to improve the sleeping conditions and problems of individuals suffering from severe sleep deprivation problems. For these cases, a full spectrum vitamin E is usually recommended.

  • Melatonin

By definition, melatonin is a sleep-regulating hormone that manages the sleep cycle and rings the alarm for your brain to switch off all other activities as it is time to sleep. The compromised production of this hormone can lead to several sleep issues and usually, melatonin deficiency is the main cause of sleep problems. 

This is also unarguably the most studied and the most used supplement ingredient of all time. A lot of companies have hopped on the trend and launched their own melatonin gummies for healthier sleep.

Contrary to popular belief, melatonin is not a sedative. Rather, it’s a strong functioning hormone that strictly regulates the sleep-wake cycle and keeps this cycle in sync. As it is triggered by darkness, melatonin tells the body when it should be tired and let the body rest, and when it should be active. 

Other than determining this cycle, melatonin also manages to add this cycle to the routine. So that you are sleeping at around the same time every day and also waking around the same time every day. 

This consistency will improve not only your productivity and sleep but also your overall health. Melatonin has an effect on the immune system, metabolism, and appetite as well. Quite a lot of reasons to keep your melatonin in check.

Dietary Habits 

Routine and daily diet cannot be ignored when sleeping issues are concerned. As we have discussed above, the causes of bad sleep can vary from person to person. It may be something medical but most of the time, they are directly linked to a messy daily routine.

Not giving yourself the right atmosphere to sleep, not giving your body enough nutrients to function optimally, not being agile enough, and not getting enough sun – the causes for lack of sleep are endless. 

However, improper sleep is directly linked with the lack of nutrients, this is why a proper and balanced diet is a must alongside supplements. Limiting the caffeine intake, cutting out the alcohol, and going easy on the carbs can make a massive difference in your sleep cycle. 

Other than the diet itself, what matters the most is the time during which you eat. A lot of doctors have recommended not eating anything sweet or full of carbs a few hours before going to bed. Giving your body rest by not eating before bed will stop the body from making excess glucose when you are trying to sleep.
