Why do we feel sleepy in warm temperature rather than cold temperature ?

The Short Answer
I learned at least one of the reasons for this from a professor last semester. He's a kineticist (that's a field of chemistry) and very into endurance running — and he told us just exactly why the perfect running temperature (high 60s to low 70s) is what it is: Pyruvate kinase Essentially, the heat outside actually interferes with the body's ability to make ATP, the energy molecule, out of the food we digest. This happens because pyruvate kinase, a crucial enzyme in ATP synthesis, is concerted mostly into a biologically inactive conformer at around 85 degrees F. This conformer is present in some portion at 70 degrees, but it's mostly the active form that dominates. After about 85 or so, you have a 60/40 ratio of the inactive to active forms. TL;DR heat slows down your metabolism and you run out of energy.
