You have stinky breath
Saliva works 24-7 to wash away food particles that collect on your tongue, between your teeth, and along your gums after you eat. If your mouth is dry, those itty bitty leftovers allow bacteria to grow, thrive, and give you bad breath, one of the signs of dehydration. Sip water throughout the day to help keep your mouth moist. And if you need a little extra freshening: chewing gum (preferably sugarless) or sucking candy (also sugarless) helps stimulate saliva. Here are some tips for staying hydrated throughout the day.
Researchers at the University of Connecticut’s Human Performance Laboratory tested the mood and concentration of 25 women who drank healthy amounts of water one day, and then didn’t over the next two days. When slightly dehydrated, the women reported fatigue, irritability, headaches, and difficulty focusing. In a separate test, men who were mildly dehydrated also experienced fatigue and had a tough time with mental tasks. But when it came to mood changes, women’s soured much more than men’s, according to the study. Scientists are still trying to figure out why. (Good luck with that.) These are the myths about hydration you need to stop believing right now.
