We've all experimented with sleep at some time or another. Here at Lifehacker we're straight up expert in experimentation (even when it doesn't turn out quite as planned). There are a few sleep experiments that even we wouldn't touch - though we're glad someone did.
Some of these experiments helped change the way we think about sleep and its importance to the human body, while others are just straight up wacky. And no, the Russian Sleep Experiment doesn't really qualify - you can read that one here instead.
Looking to get a better night's sleep? Rather than trying one of these experiments, check out our total guide to sleeping better.
