I think we should first agree on just what biohacking is. Healthline says “Biohacking can be described as citizen or do-it-yourself biology. This consists of making small, incremental diet or lifestyle changes to make small improvements in your health and well-being". I think of it as a clinical study with one participant (yourself). Should you then start doing health studies on yourself? I think you already do, and I am all in favor of more of it. If you start eating avocados and you notice your skin and hair are not as dry, you just bio-hacked. If you notice you feel alright with two glasses of wine in the evening but feel sluggish the next morning if you have three glasses...you just bio-hacked. We are biohacking every time we eat something and notice its positive or negative effects on our body. It goes beyond food. You may want to see if blocking blue light at night helps you sleep better. A continuous glucose monitor can tell you which foods spike your blood sugar. You may want to see if a supplement helps you.
Good things happen when we pay close attention to what our bodies tell us.
