alt Hacker NewsNeurotic is bad by definition, but using studies to inform your habits seems like a wise thing to do.
Obviously you shouldn't follow studies blindly, especially because many studies are poorly conducted and do not replicate, but in general, we know that just following your gut is suboptimal and sometimes dangerous in cases when studies give us clear information.
Unfortunately it doesn't seem to be easy to understand what studies are actually demonstrating, based on how often you see people making giant leaps to conclusions that don't really follow from study results.
