The Beta Wave Trap | How to Break Through Your Performance Limits

The Irony of Effort

You sit at your desk staring blankly at the monitor.

“What was I about to write?” You quietly ask yourself.

Your hands are gently floating over the keyboard, waiting for you to type your next thought. Ever since that last meeting, you've had to pause and catch your thoughts like this about 4 times. You know exactly what you need to say in your document, but for some reason the idea keeps slipping away.

Does this feeling sound familiar?

There's a huge difference between busy and effective. When the brain maintains a state of high-frequency beta waves (a constant state of alertness) for too long, your performance levels start to dwindle. But why?

Throughout the day, your brain produces a variety of brain waves. These waves are measured in frequency, which is the number of times a wave repeats itself within a second. Your brain doesn’t stop producing one type of brain wave and switch to another just because you shift into a different state. It’s more accurate to say that one type of brain wave will dominate at any given time. The dominant brain wave will determine whether you’re focused, awake, asleep, or staring blankly at your computer screen.

If you work in a fast-paced environment, you know how quickly work can pile up when you take your foot off the gas for too long. Because you want to stay on top of your workload, there's a high chance that you often work past your mental threshold. It's easy to fall for the belief that if you work as hard as you can for as long as you can then you'll get more done.

But is this really true?

Forcing yourself to power through locks the brain into a high-beta frequency. This leads to tunnel vision, overthinking and poor decision-making. We’re going to call this the Beta Wave Trap™.

If you're reading this right now, chances are you are looking to maintain your competitive edge for you and possibly your team. So, let’s dig into this further to find out how we can use our brain waves to sustain high performance and avoid the The Beta Wave Trap™.

The Spectrum of Performance

Gamma: The total recall factor

Gamma waves are the most energetic frequencies of the brain. These waves are typically associated with learning, high cognitive function and memory recall. Gamma activity has become known as a key predictor of memory performance.

In this state, you are able to make connections between different pieces of information. This helps to deepen your understanding as you learn things. Studies have also shown that an increase in gamma brain wave activity can help you achieve the highest levels of concentration, per WebMD.

Beta: The analytical workhorse (and the trap)

Beta brain waves are fast-paced electrical signals. According to Neurohealth, they are typically the dominant rhythm that most of the brain is in when our eyes are open. This state is also most active when we are making decisions, processing information, using judgment and analyzing problems.

Mid range beta waves fall between 15-18hz and can increase focus and alertness. High beta, which is above 18hz, increases alertness as well, but can also cause agitation according to Neurohealth. This is the trap. While beta waves help us with productivity, pushing too long in this state can have the opposite effect.

Alpha: The bridge to flow, creativity, and calm.

When alpha brain waves are dominant, it creates a state of mental resourcefulness. You have likely felt this way at one time or another. You notice yourself moving quickly and efficiently through tasks. Ideas come to you with ease while your mind and body are calm. This is what is commonly known as flow state.

Per research from the National Library of Medicine, alpha brain waves are a key neural marker for creative problem solving. If you want to be known as the creative problem solver on your team, or want to keep innovation high in your organization, then knowing how to alter your brain wave state is a powerful tool for you and your team.

When alpha waves are dominant we tend to experience good moods. According to Psychology Today, alpha waves are “the brain's signature of calm, wakeful relaxation, the mental state you experience in those moments of quiet focus, free from anxiety or distraction.”

Theta: Deep insights

Before you can show up for the team, you have to show up for yourself. Theta waves are common during a state between sleep and wakefulness. When these waves are dominant, this is a state where you experience creative insight, or deep internal focus. Meditation is an example of an act that may induce this state.

Theta brain waves can induce a more relaxed and quiet mind. This state also supports emotional stability according to Neurohealth. The ability to quietly reflect and gain insight from your experiences is fundamental to personal development because before you can grow within your organization, you must first grow within.

Delta: Restoration

Delta brain waves are dominant during deep sleep. As you know, the ability to experience restorative sleep is crucial for enhancing performance. As mentioned in my LinkedIn article “Why One Bad Night Makes Everything Harder,” Research from Harvard Medical School tells us that 27% of professionals report that they frequently find it hard to concentrate at work due to sleep problems.

There's more to it than a lack of concentration. The article also mentioned poor sleep causes hyper sensitivity, forgetfulness, and low patience. This could lead to important tasks falling through the cracks and overreacting. Poor sleep can also cause brain fog.

Have you ever laid down to rest at night and couldn't turn off the mental chatter? You felt tired, yet your mind was wide awake? This used to happen to me almost nightly until I learned how to manually override my nervous system. Discover how to manually change your brain waves for deep relaxation in as little as 5 minutes.

Breaking the Cycle

Knowing how to mentally reset can help you improve your creative thinking, improve your mood, decompress from high-pressure situations, and dive into deep work. Here are a few ways you can break out of high beta waves.

First is meditation. Per Newsweek, a research study led by Harvard scientists set out to uncover how meditation affects the brain. There are many types of meditation. In this particular study, they used a breath-focused practice that involved the meditator observing their breath as they unwind. Practitioners of this breath-focused meditation consistently show higher theta brain activity, which is generally associated with lower stress and improved mood.

Next is binaural beats. Binaural beats are an auditory illusion the brain creates when two slightly different frequencies are played separately into each ear via headphones. This results in a perceived third tone that helps induce different mental states. An article from Betterhelp explains that listening to binaural beats can assist with changing brain wave activity and many have reported the audio helps them improve their focus.

Another option is breathwork. While the meditation mentioned above focused on “observing” your breath, science-backed breathwork techniques act as a manual override for your nervous system. Research from the Journal of Family Medicine and Community Health has found deep breathing techniques change brain wave activity and increase the production of alpha brain waves. Deep, controlled breathing enhances activity in the prefrontal cortex and anterior cingulate cortex of the brain. These are areas associated with attention and emotional regulation.

The last option is getting outside into nature. No, you don’t need to go hug a tree. Apparently, even virtual nature can improve your mood. Seriously. A study in ScienceDaily found virtual reality forest bathing that engaged the senses showed a marked improvement on mood and well-being. While I find this absolutely fascinating, I still prefer the real thing. Going for a walk or sitting in a park is a great way to break out of a highly stressed state.

The Bottom Line

Remember, busy is not the same as effective. We have multiple brain wave states, and each has an impact on your ability to deliver quality work. When you power your way through tasks for too long, you lock yourself into an elevated beta frequency. Maintaining this state for too long makes you more prone to errors, agitation, and losing the ability to focus. In short, you become less productive.

Knowing when and how to wind down is the key to sustaining high performance. Burnout has become a hot topic in recent years because it's expensive. It costs businesses millions of dollars each year. And as for you, burnout can cost you wasted time and effort, less opportunities due to low quality work, and eventually poor health. So, start breaking the cycle today.
