Oral rehydration solution
Tho this solution was developed primarily to treat dehydration
due to disease, it works well for quickly getting fluid into the
blood, faster than plain water when you are depleted by sweating. A home made sports drink.
Where ORS sachets are not available, home-prepared solutions are typically used. While many different recipes exist to increase palatability (e.g. adding flavor, citrus, savory, etc.), all are based on a standard ratio of water, sugar, and salt.
A basic oral rehydration therapy solution is composed of:
30 ml (6 level tsp) of sugar
2.5 ml (1/2 level tsp) of salt, dissolved into
1 litre (4.25 Cups) of clean water
Note that these expedient rehydration mixtures do not replenish potassium, and usage over long term may result in hypokalemia. To obtain some potassium, 125 ml (4 fl oz) of orange juice or some mashed banana can be added to the mixture.
