Maybe you could be interested in that: could "day" be a cognate with Chinese 天 /tjɛn/, which means, well, "sky", but also: "day". So obviously from PIE we get English day, German Tag, Polish dzień /d͡ʑɛɲ/ etc. And judging from the spelling of this word borrowed from middle Chinese into Japanese, it was previously pronounced more or less like /tɛn/. So what do you think, besides that it is only one word(I didn't look, but maybe there are more?) If that was true, from a historical poin of view it could also mean a borrowing into PIE from old Chinese.
Now THIS is my kinda study/relax audio.
