The best cognitive performance hacks are those that are simple, measurable, and repeatable: sleep cycles, self-testing, memory training, and exercise. Don’t bother with gimmicks – go with what actually works.
Why Most ‘Brain Hacks’ Fail (and What Doesn’t)
Brain hacks tend not to work because they rely on gimmicks rather than actual science. A widely cited review of the subject by Daniel J. Simons in 2016 discovered that there was a lack of supporting evidence behind the claims made by commercial brain hack products.
The key is what actually works: consistency with the supporting evidence of retrieval practice, sleep quality, and exercise. If you want to improve mental performance, the key is what actually affects attention, memory, and neuroplasticity.
The 10 Hacks
Here are ten cognitive performance hacks backed by scientific research, which you can implement in your daily life.
Sleep Architecture over Sleep Duration
Sleeping more doesn’t necessarily mean you’re sleeping better. The architecture of your sleep, specifically the amount of deep and REM sleep, is important for memory consolidation.
Action: Prioritize your sleep architecture, specifically the first 4 hours of your sleep, which maximizes slow-wave sleep.
Interleaved Practice for Better Skill Retention
Interleaving, or changing between different topics, enhances your cognitive flexibility, which improves your pattern recognition skills.
Action: Instead of grouping your studies or tasks per subject, try to mix them.
The Pomodoro Technique (Backed by Attention Research)
Research indicates that your attention span, or your ability to stay focused, only lasts for 25 to 40 minutes. The Pomodoro technique, which involves taking breaks, helps improve your concentration.
Action: Work in 25-minute increments, followed by a 5-minute break.
Memory Games & Cognitive Training
Training memory has a direct effect on improving performance in specific tasks. Research has shown that when participants used a structured working memory training program, they had significantly better results in attention tasks.
Start by testing your current memory capacity using a free memory test, and then monitor your results on a weekly basis.
- Use memory games for adults that are challenging and effective
- Monitor your results to measure your improvement
- A structured approach is better than guessing and playing randomly
Action: Measure, and then train, but don’t guess.
Cold Exposure for Alert Focus
Cold exposure is a great tool for increasing your alertness and nervous system response. It is no magic pill, but it does have a short-term effect.
Action: Use cold water to improve your focus.
The Method of Loci for Retention
Spatial memory is incredibly powerful and vastly underutilized. The method of loci makes complex information come alive in the form of mental journeys.
Action: Associate information with places you know, and this will significantly increase the accuracy of your retention.
This exercise continues to be one of the most effective brain exercises for focus.
Nutritional Nootropics – What the Evidence Says
While there are certain nutrients that can aid the human brain, the benefits are not significant. Omega-3 and caffeine, however, are the only ones with confirmed benefits.
Action: First, focus on nutrition, and then consider supplements.
This is the basic foundation of cognitive enhancement and natural tactics.
The Testing Effect – Quiz Yourself
Testing oneself is not only the most effective method of assessing, but also of learning.
Henry Roediger, a renowned researcher, has confirmed the effectiveness of this method, which can increase retention by as much as 50 percent.
Action: Quiz yourself, and remember – this does not involve reading.
Exercise & BDNF
Exercise can increase brain-derived neurotrophic factor (BDNF), a factor important for learning and memory.
Action: Schedule exercise at least 3-4 times a week for brain plasticity and mental clarity.
Mindfulness for Working Memory
Mindfulness can improve attention control and decrease cognitive overload.
Action: Practice 10 minutes of focused breathing for improved working memory and mental clarity.
How to Build a Daily Cognitive Performance Stack
Stacking your daily habits creates a compounding effect. Begin with a foundation of sleep and exercise. Next, add memory training and testing to your stack. After that, add your focus tools, such as Pomodoro or mindfulness.
A basic cognitive performance hack: thinking of morning exercise, a focused work session, memory recall, and a review session in the evening. These cognitive performance hacks build upon one another, increasing cognitive speed and clarity, which are two of the most important elements of how to think faster.
FAQ
Can you really improve cognitive performance naturally?
Yes, sleep, exercise, and memory training have the most scientific evidence supporting them.
How long before cognitive hacks show results?
Most cognitive performance hacks will bear results within 2 to 4 weeks of consistent practice.
What is the best free tool to test working memory?
MemoryOS has a chimp test that effectively tests your visual memory and digit memory span.
