You can make an inexpensive homemade rehydration drink. Measure all ingredients precisely. Small variations can make the drink less effective or even harmful. Mix:

• 1 quart (950 ml) water


• ½ teaspoon (2.5 g) baking soda


• ½ teaspoon (2.5 g) table salt


• 3 to 4 tablespoons (45 to 60 g) sugar


• If available, add ¼ teaspoon (1.25 g) salt substitute, such as "Lite Salt".
