Harper Recommendation

For beginners, I recommend starting with the science of sleep, exercise, nutrition, and human physiology before exploring more advanced biohacking trends.

Think of biohacking as an opportunity to become a better observer of your own health—not as a replacement for medicine or professional healthcare.

A simple approach is often the most effective:

Learn → Observe → Track → Evaluate → Adjust.

Start with one healthy habit, collect useful information, and give your body enough time to respond. Avoid changing everything at once.

The goal should not be to "hack" your body at any cost. The goal is to understand your body better, make informed decisions, and build sustainable habits supported by reliable evidence.
