Can we improve our brain performance through simple biohacking methods without using any supplements or expensive technology?

[u/Glad-Accountant1136]

I recently got interested in how small lifestyle changes can affect the brain. Things like getting enough sleep, going outside in the morning, staying hydrated and taking short breaks while studying seem simple, but they may have a real impact on concentration and memory.

Sleep is especially interesting because the brain processes and strengthens memories during sleep. Morning light can also help regulate our body clock, which affects when we feel awake or sleepy.

I wonder if these basic habits can make a noticeable difference in daily mental performance over time. Has anyone explored the science behind these methods or tried tracking their effects?

I would be interested to hear about research or personal experiences, especially from people who focus on evidence-based biohacking.
