5 ways to increase deep sleep for better brain health ūü߆ ūüí™

We'll be honest, improving deep sleep is not always an easy fix. There are, however, some fundamental things you can do to help your brain find its natural 'deep sleep' grooove to help you thrive, mentally and physically. 

Before we start, you might be wondering what deep sleep is and why scientists say it's so important to get better deep sleep?! For the long version, check out our recent blog here. 

For the short version, you can read on for all things sleep improvement! Deep sleep, also known as slow-wave sleep, is our third non-rapid eye movement sleep stage[1]. If you were hooked up to an electroencephalogram (EEG), you'd see lengthy, slow electric waves called delta waves (see what we did there with our product name?!). 

Deep sleep (and therefore ways to improve sleep) is essential as it is responsible for everything from memory [2] and motor skills to repairing tissue, muscles, and your immune system [3]. AKA, that sweet deep sleep is pretty influential, right? Read on for five ways to increase how much deep sleep you're getting...

Practice Sleep Hygiene: Restful routines 

Making sure you set yourself and your environment up for success could be an easy win to increase deep sleep and improve sleep quality, you may find you fall asleep quicker too. 

Best-practice sleep hygiene is having a set daily routine to keep your circadian rhythm at its optimum, such as waking and sleeping at the same time each day, and making sure you are exposed to natural light in the morning [4]. This will help your body regulate melatonin levels naturally, so you feel you can step away from OTC melatonin pills. 

It's also helpful to avoid the doom-scrolling right before bed and try to wind down your mind away from blue-light screens and devices [5]. Physically speaking, the saying "clear space, clear mind" applies to sleep, too. Try to ensure a cozy and comfortable bedroom with no distractions or interruptions at night. A restful environment goes a long way when searching for dreamland.

Fuel your body: A 'Diet' for drowsiness  

Food can be one of life's natural remedies for deep sleep. It's worth saying that nutritional needs vary between people; everyone is different. However, feeding your body with healthy, brain-nutrient-rich foods is an excellent step to take. For example, things like omega-rich fish, inflammation-busting turmeric, and antioxidant-rich veggies may help give you the fuel your brain needs to work more efficiently and effectively [6]

Why? Research shows these things help your gut, and further research has speculated that your gut's microbiome may help regulate brain behavior, with the microbiota-gut-brain axis affecting your sleep cycle [7]. In theory, eating a nutrient-dense diet alongside pre and probiotic fibers such as chicory root, kefir, and kimchi, could help you increase your deep sleep and regulate your rem cycle. 

Laying off the caffeine six hours before bed [8] and avoiding alcohol before sleep will also help your body focus on getting some Zzzs! *puts down wine and picks up herbal tea*

Move your body: Exercise your way to deep sleep 

Wondering what else you can do to increase both REM and deep sleep? Exercise! 

If you’re struggling with sleep, it doesn’t take a neuroscientist to predict that you’ll probably be feeling tried and groggy. Although exercise may be last on your list, it’s worth moving it up the to do list to avoid the sleep and exercise vicious cycle [9]. Not enough exercise > poor sleep > poor sleep > no motivation to exercise. The cycle continues! 

Talking of cycling, or running for that matter, research has shown that moderate-intensity aerobic exercise (otherwise known as anything that gets you out of breath with your heart pumping ūü•Ķ) can decrease the severity of sleep disorders,¬† improve sleep quality and decrease sleepiness in the daytime.¬†

Watch out; intense exercise before bedtime can increase your heart rate and make it harder to drift off [10]. If you‚Äôre looking to wind down before bed, maybe stress-reducing yoga is your answer ūüßė.

Mindful Moments: Don’t overthink it!

Mindfulness has hit the mainstream, and although you may feel some aspects are gimmicky, taking a moment to yourself can help you decompress and begin to get into that sleep zone. 

Meditation may help reduce stress and anxiety by allowing the brain to just be, leaving conscious thinking behind and helping you feel calmer and relaxed [11]. 

If you really can’t sleep (maybe because you’ve not tried DELTA yet…), try not to put too much pressure on yourself to nod off. Instead, you can try to remove yourself from your bed and partake in a restful activity such as meditation or reading your least favorite book, away from screens and devices. Hopefully, this will help your brain power down for the night.
