1/2 gallon or 2 liters of water in 80F or 26C is barely enough for an adult doing nothing but sitting in the shade watching the grass grow. If you're gardening, mowing the lawn, cutting trees, riding your bicycle or playing baseball, you need about 1/2 quart or 1/2 liter of water per hour.
Alcohol is a dehydrating agent, so sipping an ice-cold high-ball or gin and tonic will work against you as well.
I had to dig through my files to find this - dates back to my Coast Guard days, but here's the recipe for a homemade rehydration drink, much less expensive than the name brand stuff!
Homemade Rehydration Drink
[i]The envelopes with non Kool-Aid drink mixes (like Wylers) are usually more like Gatorade. Kool-Aid seems to have its own distinct flavor.
1 (1/4 ounce) envelope unsweetened flavored drink mix (enough for 2 quarts)
1/2 teaspoon table salt (sodium chloride)
1/4 teaspoon salt substitute (potassium chloride; eg. Morton Salt Substitute)
1/4 cup sugar
1/4 cup plus 2 tbs. corn syrup or honey
2 tbs. lemon juice
water, to make 2 quarts
8 servings
3 minutes prep
Place all ingredients in a large pitcher or jug and stir or shake until well mixed.
Chill and keep refrigerated until used.
Note: Adjust sweetness to taste by adding (or in rare cases reducing) a little sugar since drink mixes can vary.
