It works, eating/drinking something cold on a hot day only gives a very
temporary "cool" feeling. Your body compensates by raising its internal
temperature and overshooting making you feel even hotter.

It is the very same hysteresis effect you will notice with sugar. You
fell like you are dragging so you eat a candy bar. Now you suddenly feel
great because your blood sugar goes up. Then your system produces a
large amount of insulin to compensate for the sugar but since all that
sugar isn't natural it produces too much insulin which causes your blood
sugar to spike low causing an even heavier dragging feeling than before
you ate the sugar.
