It doesn’t take much to become dehydrated. Lose just 1.5% of the water in your body (the human body is usually about 60% H2O), and you’ve reached the tipping point of mild dehydration. It can be brought on by many things-and it can do much more to your body than just make you feel thirsty. Dehydration also brings on health effects ranging from fatigue and smelly breath to more dangerous consequences like distracted driving.
It gives you bad breath
It’s easy to forget to drink water during a busy workday, but at the end of the day you may find people standing unusually far from you when you open your mouth. “Dehydration can give you bad breath,” says Marshall Young, DDS, a dentist in Newport Beach, Calif. “Saliva has important antibacterial properties. When dehydrated, the decreased saliva in the mouth allows bacteria to thrive, resulting in bad breath.” So drink up for your own sake, and for those around you as well.
It makes you crave sugar
Dehydration can mask itself as hunger, particularly sugar cravings. This may happen particularly if you’ve been exercising, says Amy Goodson, RD, sports dietitian for the Dallas Cowboys. “When you exercise in a dehydrated state, you use glycogen (stored carbohydrate) at a faster rate, thus diminishing your stores more quickly.” So once you finish exercising, you will likely crave carbs to help you replenish those glycogen levels and get you ready for your next exercise bout.
