This study purports an over 200% increase in cognitive function due to smelling oils at night. Either this is the dumbest scam ever or deserves the Nobel prize.
It is known for a longer time that reproducing knowledge is somewhat better when it occurs in the same environment as learning took place. This might capitalize on that, but not really, as odor in learning and testing doesn't score well. But I agree, it might also be a fluke, bad design, drawer effect, etc.
The statistics are not convincing. When I look at the difference between LS and LST on the last day, LST has a lump in the middle, which would mean most learners didn't benefit. LS is on average lower, but one or two bad learners in that group would account for the whole difference. So I'm not convinced.
And then there's the "no significant differences in sleeptime" spiel, which is 100% bollocks.
>The study was supported by Procter & Gamble.
Neat if true, but... I'm not holding my breath.
In seriousness though, I've come across decently plausible information in the past that suggests that the volatile chemicals given off by natural wood has calming effects.
Of course! After all you'd want to take in all the aromas!
That could be true, def can't be harmful. So I hoped people would lean towards natural aromas after reading. Like opening the window to the garden, more flowers in the garden, etc.
Frankly, if true it would be a great product opportunity for P&G, as well as a social good, so I don’t begrudge the study.
