In my view, the following suggestions may do some help to improve cognitive abilities:
First of all, ensure you get enough sleep. Insufficient sleep probably reduces a person's attention span and reaction speed. More importantly, lack of sleep can cause permanent damage to neurons.
Secondly, do some training to exercise your brain. Activities such as reading, learning new methods, or even simply memorizing a poem can serve as good mental exercises. Through consistent practice, the brain can stimulate neurogenesis, which enhances cognitive function. Another highly effective learning technique is the Feynman Method: if you want to master a subject thoroughly, try teaching it to someone else and ensure they understand it. This is also an excellent way to improve perspicacity.
Additionally, it helps to focus on an area you are genuinely interested in. As the old saying goes, “Interest is the best teacher.” Alternatively, you can choose a field that comes naturally to you. Everyone has their own strengths and can excel in certain domains.
Last but not least, avoid remaining in high-stress situations for too much time. Scientific research has shown that over-stress negatively affects the brain, often hindering clear thinking and slowing down mental processes.
By integrating these habits—prioritizing rest, engaging in mental exercise, pursuing your interests, and managing stress—you can create a sustainable foundation for long-term cognitive health and performance.
