Regarding sleep temperature, I've seen contradictory recommendations.

This article references a finding that "finding that facial warming helps send people to sleep". And Wikipedia writes

Some of the few factors known to increase slow-wave sleep in the sleep period that follows them include body heating (as by immersion in a hot tub)...

Though, this guy writes

"A hot bath will increase your skin temperature, which eventually decreases your core body temperature. Do the same thing for yourself that you’d do for a young child—make sure you take a bath a half hour or so before bed time.” — Robert Oexman

And this pdf recommends staying cool.

I experimented with gradually reducing my blanket load while sleeping but I found that past a certain point I would wake up chilly in the middle of the night and put blankets on in order to fall asleep again. So empirically that seemed to disrupt my sleep.

It seems like the outlier data point is the Fast Company quote. I sent an email to the company working on SomNeo to see if they could send me the study they based their decision on. I noticed that the study you cite was a pilot study without that many participants, and results on insomniacs don't obviously generalize to the larger population.
