Hydration Myths: Thirst, Urine Color, and Overdrinking
About this Capsule
The eight-glasses rule has survived decades without evidence behind it. These myths cover the fixed daily quota, the fear of chronic mild dehydration, and the overlooked danger of drinking too much. Unpacking them leaves you with a simpler guide: thirst, urine color, and your own body's signals.
These myths differ on whether everyone needs to drink a fixed amount of water daily or if hydration should be personalized by listening to thirst and urine cues. Some myths warn about the dangers of drinking too much water, while others challenge the old idea of eight glasses a day. This capsule helps you decide when and how much to drink based on your body's signals and health needs.
