Mark Ottobre says total darkness in your bedroom matters for sleep and muscle growth. He means pitch black, where you can't see your hand in front of your face. It's the sleep hack most people skip.

You have to sleep in a cave. There has to be absolutely no light that penetrates the bedroom. You want it pitch black to the point that if you were to put your hand in front of your face, you should not be able to see your hand. That's how dark you want your room. And if you want to build muscle seriously and build as fast as possible, and we want to optimize sleep, we want to sleep in darkness.
