Is there any physics to do with barometric pressure involved? Why would it make us sleepy? If it does have to do with barometric pressure and lower pressure reduces our alertness, is there an ideal pressure for maximum alertness and maybe even learning and memorization? Maybe we should pressurize schools so the learning environment is maintained at "fair weather" levels through the dreary winter months. I will be choosing a serious answer as the best answer.

The answer probably lies in thinking outside the square.

iron is number 26 in periodic table, so it has 26 atoms, but HOW?
if we cut iron bar into half and look under microscope, both sides will have 26 atoms, so how come 1 bar of iron has only 26??????????????
