Pur-pee, my initial impression was that you experienced heat stress.

When the humidity has reached a certain level the body cannot continue to cool it efficiently and starts sending signals that it's overloaded--like chills. In very humid weather it's wise to slow down, drink lots, and take several breaks in the shade. Eating frequent large snacks may actually work against you and may add to your misery. (In very humid days I carry an extra water bottle to douse me when I can't get cool.) It may take you longer to recover from this ride and it's best to listen to your body and give it what it needs--lots of rest and fluids. Put on your jammies, lay on the couch, and read or watch t.v.
