Why You Need to Be Rehydrated, Part 1


by Rey Beltran |

We’re now in the middle of the year, and the heat index is still hitting more than 40 degrees… we profusely sweat even with the littlest effort. We all feel lazy and, as much as possible, we limit our movements and effort to do things. And we drink a lot of water. That’s because we don’t want the heat to get the best of us, do we? So let’s do a rundown of the effects of dehydration to our bodies.

But first, some facts: Did you know that losing just 1.5% of water in your body means you’re already mildly dehydrated? Yes, because the human body is about 60% water, we are easily dehydrated during summer. You wouldn’t think about that 1.5%, but mild dehydration can do more than just make you feel thirsty. Here’s a rundown of the effects of (mild) dehydration to our bodies:

Bad Breath

Admit it or not, you usually forget to drink water when you’re all too busy during the day. So don’t wonder if people will stand a little far from you when you talk to them. According to Marhall Young, a dentist in Newport, Beach, California, “Saliva has important antibacterial properties. When dehydrated, the decreased saliva in the mouth allows bacteria to thrive, resulting in bad breath.” So there you go, you need to drink up lots of water during the day!

Sugar Craving

Yes, dehydration can be mistaken for hunger pangs, especially for something sweet. This happens when you exercise in a dehydrated state. According to Amy Goodson, RD, sports dietitian for the Dallas Cowboys. “You use glycogen (stored carbohydrate) at a faster rate, thus diminishing your stores more quickly.” That means, when you finish your exercise, you will crave carbs to recover lost glycogen during exercise.

Poor Workout Performance

Goodson also added that “[a] 2% dehydration level in your body causes a 10% decrease in athletic performance.” Aside from sweating it out during exercise, you tire easily. So when you work out, better drink water to replenish lost water from the body.

Dry Skin

We all know that drinking lots of water makes our skin healthy and glowing. This is seconded by Anne Marie Tremain, MD, a dermatologist in Long Beach, Calif. “Depending on your lifestyle you may need to adjust your water intake.” If you regularly work out, or you love to drink coffee, you need to drink more water. That’s because when you work out, you sweat a lot, and you lose water. As for coffee, it is a diuretic; that means it induces you to pee. Drink water when you drink lots of coffee.
