5 Ways to Increase Mental Processing Speed

5 Ways to Increase Mental Processing Speed

People can’t seem to agree on much these days, from what to watch on Netflix to what’s a healthy diet, but there’s one thing nearly everyone has in common: fatigue. We’re all tired, mentally, as well as physically, and it’s taking its toll on our processing speed and thus on our personal and professional lives. Let’s change that; here’s a post on how to increase our mental processing speed.

In 2017, a Dutch study found that 16% of company employees aged 15–75 experienced work-related mental fatigue several times per month, and people between 25 and 34 reported the most incidents. Thirty percent of employees said they felt drained at the end of a working day, while 20% complained of feeling that way in the morning when they started work. To be truthful, I can relate all too well with this. There was a time I was a kind of tired that no amount of sleep could cure. 

If you want to build a successful career, get through school, or run a business, you probably won’t be able to limit mentally-draining tasks or avoid making tough decisions. Still, you can take steps to keep your mind as focused and sharp as possible in spite of the challenges it faces so that you have the superhuman processing speed.

It’s not that challenging, really… In a world where everyone is so disengaged and distracted, getting slightly healthier, stronger, and faster will make you look like you have the mental processing speed of a demi-god in comparison.

How Can I Increase My Mental Processing Speed?

“Of course motivation is not permanent. But then, neither is bathing; but it is something you should do on a regular basis.”
―Zig Ziglar

The route to faster processing speed, concentration, and understanding is recognizing the connection between what’s going on around you and what’s happening inside your brain. Your mental state is dependent on both internal and external factors.

Here’s an example: “In the 90s, it was so hard to get a reservation at a famous restaurant in New York that [the restaurant] started getting a lot of complaints. So they had psychologists come in to find ways to get people in and out faster. They found that the two biggest difference makers were installing brighter lights and playing faster music, which shows how our external environment subconsciously shapes our mental state.”

The trouble is when we allow outside factors like 24/7 email, fast-paced work environments, and constant stimuli to speed us up too much, our performance suffers. That’s when we have to work on our inner [mental] game to slow things back down. Conversely, when we’re feeling sluggish, we need a toolkit of techniques that can energize us so we can perform well even when conditions aren’t ideal.”

Certain foods and supplements, along with daily practices such as meditation, brain breaks, and better sleep habits, can all alter your mental state significantly, allowing you to speed up or slow down as needed to find the level of mental sharpness you require to be more focused and productive.


Can Natural Ingredients Really Affect Your Mental Processing Speed?

“When obstacles arise, you change your direction to reach your goal; you do not change your decision to get there.
―Zig Ziglar

Everyone knows that caffeine can help with alertness and focus. Still, there are so many other natural compounds that, when combined with caffeine or without caffeine (for me), maybe even more effective for supporting a sharper mental state.

We all know that certain foods make us slow and sluggish. This is mostly due to inflammation in the brain–colloquially referred to as brain fog. Sugar, ultra-processed food, and alcohol are common culprits here. 

Knowing that certain foods cause inflammation, does it not stand to reason to assume that certain foods can have neural anti-inflammatory effects?

green tea leaf L-Theanine

L-theanine is an amino acid found in green and black tea, and a trial published in Pharmacology, Biochemistry, and Behavior concluded that it helps lower the body’s stress response to stressful cognitive tasks [1]. In other words, it may be able to help chill you out when you’re working on something frustrating. This calming effect could help to balance caffeine’s stimulant properties.

A study in Biological Psychology looked at the effects of caffeine and L-theanine in isolation and in combination, discovering that the two compounds together boosted cognitive speed, memory, and alertness better than when either nutrient was taken alone [2]. Another study in Nutritional Neuroscience noted that while caffeine by itself boosts alertness when teamed with L-theanine, it helped promote speed and accuracy on attention-switching tasks and reduced susceptibility to distraction [3]. The researchers also noted that L-theanine might help attenuate the spikes in blood pressure associated with caffeine use. This doesn’t necessarily mean it can counter the jittery and restless feelings that often accompany caffeine, but L-theanine seems to help you harness caffeine’s stimulatory effects, leaving you feeling alert but not overly revved up.

If ruthless focus is a topic of interest to you that you would like to explore further, I wrote an article on mastering flow. Not everything I write or say is useful. This one, however, I would class as top 5 in anyone’s Swiss army knife of skills.

L-theanine is available as a supplement in universal formulations like Maximum Mind for example, but if you want to keep it simple and stick to coffee, at least get the dosing right, which can minimize the risk of caffeine’s side effects. The sweet spot for caffeine appears to be between two and three milligrams per kilogram (2.2 pounds) of body weight a day. This is a level that provides most of the benefits while limiting the drawbacks of excessive caffeine intake, like restlessness, anxiety, and inability to focus.

Another natural ingredient worth experimenting with is Huperzia Serrata that contains the very interesting compound huperzine A. It’s been shown to help people with cognitive deficits, potentially by way of regulating oxidative stress and supporting nerve growth factors and receptors [4]. It also acts to help promote acetylcholine concentrations, allowing for neuron communication [5]. Lastly, Lion’s Mane Mushroom has been shown to do that which we used to think was impossible: create new brain cells in healthy adults. Needless to say, what multiplying brain (a process called neurogenesis) cells do.

Note: there’s an effective dose of L-theanine from organic green tea leaf extract in each dose of Maximum Mind.

The Lost Art of Superior Mental Processing Speed

“I never lose. Either I win or learn.
―Nelson Mandela

Here are four simple ways to boost your mental processing speed fast.

Follow a Low-Carb Diet

Lowering your carb intake has been shown many times over to help people lose weight and reclaim their health, but one of the first noticeable benefits is improved thinking and concentration. This is because low-carb eating helps you avoid blood sugar spikes that rob your energy and fog your brain. Taking a step further, a low-carb diet becomes a ketogenic diet, where the lack of carbohydrate intake causes your body to run on ketones (compounds made from fat) for fuel.

A team of psychiatrists and neuroscientists divided adults with mild cognitive impairment into two groups. The one that followed a low-carb diet for six weeks showed improvements in verbal memory performance [6].

Sugar is not your friend. Food, in general, is not your friend. 

As reported in Scientific American, a ketogenic diet may benefit the brain by inhibiting stress on neurons, increasing the number of mitochondria (energy-producing structures in brain cells), and regulating neurotransmitters to ensure a balance between excitation and inhibition.

One of the biggest foundations for achieving and sustaining a high level of mental processing speed is optimal blood glucose control. With half the US population struggling with pre-diabetes or diabetes (don’t think it’s a US problem only), it’s perhaps not surprising that mental performance seems to be on the decline. Chronically high blood glucose levels wreak havoc on the brain, entangling neurons and increasing your risk of dementia and depression. 

Look at it this way. If what you’d call a “drug” is something you take from a plant, extract and purify to have concentration levels unseen under untouched circumstances, then what is table sugar?

Reducing carbohydrate intake can be an effective strategy for improving glucose control, especially in those with pre-diabetes or diabetes, as a reduction in carbs significantly reduces your postprandial glucose response. So, if you find yourself falling asleep at your desk after lunch, reducing your carb intake can be a great tool for supercharging your brain game.

Get More High-Quality Sleep

At the risk of sounding too harsh, lack of sleep is making you stupid. One of the world’s leading sleep researchers, William Killgore from Harvard Medical School, wrote in Progress in Brain Research that sleep deprivation not only slows response speed and compromises alertness, attention, and vigilance but also affects “more creative, divergent and innovative aspects of cognition.” Said another way, if you don’t sleep well, your brain just won’t work right. And no matter how many extra shots you get your favorite barista to put in your morning joe, they can’t overcome the detrimental impact of a bad night’s sleep.

Even a single night of bad sleep reduces your inhibitory control (which can be thought of as the willpower bank), making you more likely to react emotionally to conflicts and engage in risk-taking behavior. In fact, even after you catch up on your sleep, there’s a major lag time before your full cognitive performance is restored. If you’re serious about your mental performance, prioritize increasing total sleep time and quality above all else. Sleep is like a buffet. Quantity is more important than quality. 

So how can you start sleeping better? Get all the electronics out of your bedroom, keep it dark with blackout shades and cool with air conditioning, a fan, or a chiliPAD, and trade your tablet or eReader for a good old-fashioned paper book to help you wind down before bed. You might also want to consider taking a supplement that contains magnesium, which may help you avoid delayed sleep onset and early wakefulness, as well as improve sleep efficiency, according to a trial in the Journal of Research in Medical Sciences [6].

Have Brain Breaks

If you remember the restaurant example above, playing up-tempo music and sitting in bright lighting helps you move faster. As we showed in our report on forest bathing, taking a leisurely stroll outside can help you relax significantly. In both cases, the environment you surround yourself with creates changes in your brain.

If you’re in a mental slump—which hits a lot of people mid-afternoon—then step away from your desk and take a quick walk outside. Or, if you’ve got a meeting coming up, just take a stroll around the building and have a chat with a colleague. The change of scene will give you a mental lift. Don’t think of it as time wasted, but rather an investment that will provide greater clarity and focus. The more consistent you are with any mindset practice, the bigger the benefits you’ll experience.”

Findings published in Mental Health and Physical Activity noted that just 12 minutes of activity helped promote mental processing speed in elementary school kids [8].

Schedule Meditation

While walking in nature can be a form of meditation, the value of sitting quietly with your eyes closed can’t be overstated. A study that spanned several years concluded that brief meditation practice could help promote improvements in attention span and processing speed [9]. Moreover, results could be observed after only four brief meditation sessions. 

If you only have a few minutes to improve processing speed, then fire up a guided meditation on an app like Headspace or do a little single-point meditating by focusing on your breath. Picture yourself inhaling relaxation and exhaling stress. You could also do color breathing, in which you picture yourself inhaling a calming blue and exhaling a warning color like red.

A group of researchers published a paper in Nature Reviews Neuroscience that showed how calm breathing impacts a group of nerves that are directly tied into the arousal centers in the brain [10]. The more control you have over your breath, the more you have over your mind. They also noted that breathing techniques similar to the ones found in yoga improved performance on cognitive testing.

Can Blue Light Help Your Processing Speed?

Blue light is a color in the light spectrum that travels at short wavelengths. It’s produced by the sun, but also by artificial lights, and scientists believe that exposure to it can help us focus and

learn, hence why we should stay away from it in the late evenings. Yet, harnessing the power of blue light during active hours is a fine idea.

A study published in the Journal of Neural Transmission concluded that a significant increase in alertness and speed of information processing could be achieved by blue light [11]. Furthermore, the study also shows that subjects who were exposed to blue light for 30 minutes after a learning exercise improved memory retention compared to the placebo group.

One of the best ways to get exposure to blue light is simply going outdoors. Getting outside is hugely important for cognition and mental health, particularly during fall and winter months.

If you’re bold enough to tackle the elements with a morning walk to work or to your favorite coffee shop, your brain will be exposed to over 100,000 LUX of light intensity, even on cloudy days, which will kickstart circadian rhythms and cognition.

A brightly-lit office, by comparison, puts out only a paltry 20,000 LUX. Getting outside to burn off the brain fog and clear your mind before work is an excellent practice, or add outdoor morning workouts to further increase the benefits.

There was also an article in Cell lately showing the effect witnessing sunrise and sunset have on mood and general life outlook. Long story short, it makes everything better [11], from mood to processing speed. However, the researchers observed significant benefits after two weeks or repeating the behavior only. Meaning if it makes you happy to rise with the sun and look at sunsets every now and again, the science says it’s likely to make you even happier while increasing your processing speed if you do it regularly.

However, there can always be too much of a good thing. Certain biohackers will warn you that blue light can mess with your sleep, as it suppresses the release of melatonin. It can delay the onset and reduce the quality and duration of sleep. For these reasons, it’s a good idea to wear glasses that block blue light when you’re watching TV or using electronics at night. They don’t need to be fully dark red. Any degree of shading will help to some extent. 

Also, cut off your exposure to as much artificial light as you can at least two hours before going to bed (dim the overhead lights, turn off the TV, etc.). But don’t think you have to live in a cave just to be able to sleep at night.

That’s it for now. We covered important ground on processing speed and ways to improve it quickly.
