hello i am korean and i want to help something with your korean. actually it is a hard question to korean too😂 and some of native koreans don't care about that like me. but if you want to make a centence with correct vocabulary, increase's uses is like a chart, you know what i am sayin. and raise is like invisible thing like money. my explaining is so poor but i hope that i helped little with your korean. :)

i think first one is better than second one. cause the reason that you drink decaffeinated drinks is you need eight hours of sleep

I hope, but Ima not a native speaker ;(
