Don't know what it's like where you are, but here in the Boston region temps and humidity have been in the 90s. Everyone should remember to drink lots of water well before you feel totally thirsty. I've been mixing my own sports type of electrolyte replenishment drink. Very easy to do, just google homemade rehydration drinks. The potassium, sodium, etc. helps your body better absorb water. A bit of sugar and fresh lime or lemon juice, too. Frozen hot chocolate from Dunkin' Donuts is also amazing.
