Reality: Again, it depends on what you mean by “dehydrated.” Experts like Vasey posit that while those walking around in a state of subclinical dehydration may not feel thirst, their bodies are sending other signals of inadequate hydration – from headaches and stomachaches to low energy to dry skin.
But when it comes to avoiding the more widely accepted definition of clinical dehydration, thirst is a good indicator of when you need to swig. Here’s the deal: As water levels in the body drop, the blood gets thicker. When the concentration of solids in the blood rises by 2 percent, the thirst mechanism is triggered. A 1 percent rise in blood solids could be called “mild dehydration,” but it could also be considered a normal fluctuation in bodily fluids.
Either way, feeling thirsty is a good indicator that you need to get some water into your body, and soon. Serious symptoms of dehydration don’t arise until blood solids rise by 5 percent – long after you feel thirsty. But, obviously, you don’t want to wait that long. Even mild, subclinical levels of dehydration come with sacrifices in optimal vitality, metabolism and appearance. Like an underwatered plant, the body can survive on less water than it wants, but it’s unlikely to thrive.
Bottom Line: Drinking water only when you’re thirsty may relegate you to being less than optimally hydrated much of the time, and it may undermine your energy and vitality. On the other hand, constantly sipping or gulping calorie- or chemical-laden beverages for entertainment is a bad idea. So if you tend to keep a bottle of soda on your desk all day, or if you’re never seen without your coffee cup in hand, rethink your approach. Get in the habit of drinking a glass of water first thing in the morning, and a few more glasses of water throughout the day. Also drink proactively (especially important during strenuous exercise, long airplane flights and in hot weather).
