10 Cool Ways To Hack Your Brain

9. Use Gestures To Prepare For A Test

Students use a variety of techniques to help themselves retain information before an upcoming test, from the traditional writing things down to the more new-age yoga before a studying session. As all of us know, though, most of those techniques are hit-or-miss, as no one has been able to perfectly figure out the best way to guarantee memory retention. While we’re not claiming to have solved pre-test preparation, there’s one scientifically proven method you can use that definitely works: using gestures while studying.[2]

Studies have found that when you use gestures to explain the information to yourself, the brain retains it far more effectively than, say, speaking it out aloud or even writing it down. In fact, in one study, researchers found that only speaking while learning a concept had no effect on information retention at all.


8. Use The Sun To Hallucinate

While we’d like to reiterate our stance against abusing drugs for recreation, we have to admit that hallucinations are awesome. There are a few things as fun as making the brain see things that aren’t there, but because illicit drugs seem to be the only way to do it, many people never get to experience it. If you’re one of them and would like to know how it feels without being on the wrong side of the law, there’s some good news. As one physiologist from the 19th century found out, all you need to hallucinate without drugs is the Sun.

Just close your eyes and point them toward the sun. Then wave your hand back and forth across the face while keeping one eye covered. Pretty soon, you’ll start seeing shapes, and while the exact figures vary according to person, you can expect hallucinations like spirals, hexagons, or squares.[3]

Another way you can legally hallucinate is by exploiting something called the Ganzfeld effect, wherein the brain fills in visual information of its own after long periods of sensory deprivation. Just put a piece of white paper over your eyes, lie down under bright white light, and use noise-canceling headphones to block out any sound for 20 minutes. When you get up, you’d be treated to some good old visuals (as they presumably call them in the world of illegal drugs).
