Watch Out for These 5 Unusual Signs of Dehydration

Did you know more than half of your body is made of water? Water aids in many of the body’s vital functions, including regulating body temperature, lubricating joints and aiding in digestion.

It doesn’t take much to become dehydrated. Losing just 2 percent of your body’s water content will cause mild dehydration.

Spot dehydration before it becomes a problem by looking for these signs.

Bad Breath

Saliva has anti-bacterial properties and when you’re dehydrated, saliva levels go down. This can lead to bacterial growth that causes bad breath.

Blurry Vision

Dehydration can lower water levels in your body, which can cause your eyes to become dry and irritated, resulting in blurred vision.

Food Cravings

Feeling hungry? Instead of grabbing a snack, you may need to drink water. When we’re dehydrated, our body sends signals to the brain that may be misinterpreted as hunger when we’re actually thirsty.


Water helps keep your blood flowing and when you’re dehydrated, less blood flow gets to the brain. This can cause headaches, and in extreme cases, light-headedness and dizziness.

Lack of Sweat

Sweating is one of the ways your body regulates its internal temperature. If you’re not sweating after a workout, it could be a signal that your body is dehydrated and holding onto water. If your body doesn’t cool down, you could be at risk for heat exhaustion or heat stroke.
