With high-end restaurants offering diners tap water and concerns about the health and environmental impact of plastic bottles at an all-time high, NPR sets the record straight about some common myths related to drinking water:
- Not only is drinking 8 glasses daily not necessary, "nobody really knows" where that advice originated, says one expert.
- Water doesn't help the kidneys filter toxins.
- The fluids already in you dwarf the amount of water in a few glasses, so any benefit to skin is minor.
- It may be helpful in making dieters feel full, but extra water doesn’t lead to weight loss.
- True dehydration during a workout requires a lot more water loss than a recreational athlete is likely to experience.
