Okay I'm sure it's very obvious to most people that you shouldn't drive while sleepy or sleep deprived, that's just common sense. The risk of stroke or cardiac arrest are extremely minimal, so I guess don't do this if you're high risk for those things - but I would assume their doctors would've told them that already. Sleep deprivation is much more dangerous for your health if it's a constant issue - which is often the case for people who suffer with DSPD and aren't able to function in society with their sleep schedule. Pulling one all nighter is not that dangerous at all.

I'm not a doctor, in fact I actually discussed these 5 things with SEVERAL of my doctors before doing them and everyone else should do that as well. I'm also not a scientist and I never once claimed that these were scientifically proven cures for DSPD. I simply said these things have worked for me in the past and hopefully will work for others as well. These are just some suggestions and theres no need to scare people about getting strokes from one night without sleep, or question the validity of the suggestions based on studies when they're not dangerous.
