“They compared each participant’s brain activity on two separate nights — one when they consumed caffeine capsules three hours and then one hour before bedtime, and another when they took a placebo at the same times.”

As someone who consumes lots of coffee I worry a little about that and always read caffeine articles but in this case doesn’t everyone already know caffeine right before bed is a bad idea?

Sorry for the sass, but it's so tiring to have one's circadian clock ignored all the time - or worse, met with tips and techniques on how to "fix" it.
