Signs of Dehydration

10 Signs you’re dehydrating….

Water is vital to our survival, that’s common knowledge. Still, the occasional bout of dehydration can catch our anyone. So what can we do to stay hydrated and what are the most common signs and symptoms we’re not drinking enough water?

10 Signs of Dehydration

1. Over heating

Sweat is the body’s natural liquid cooling system. But to keep this system running efficiently, you’ll need to stay hydrated. When the body is dehydrated, sweat glands stop working and we can quickly overheat.

2. Crying

Although crying isn’t something most people do on a regular basis, crying without producing tears can be another sign of dehydration.

3. Tiredness

Water helps regulate the body’s blood stream and blood pressure. But when we’re dehydrated, blood volume and blood pressure may drop to levels that affect oxygen in the blood, and without sufficient oxygen in our muscles, we become easily fatigued.

4. Lightheadedness

A drop in blood volume, blood pressure and oxygen levels in the blood can also cause bouts of dizziness and in some cases, can even make people faint. This sudden rush of lightheadedness often occurs when we stand up too quickly and is medically known as orthostatic hypotension.

5. Muscle Cramps or Spasms

Dehydration has also been shown to affect muscle functions, resulting in cramps or periodic spasms. While the cause of this is remains a mystery to science, many experts believe it occurs due to an imbalance of electrolytes.

6. Heart Palpitations

The heart is the most important muscle in the body, and just like all other muscles, it needs a hydrated healthy environment to function. If the heart experiences a drop in blood flow, blood pressure or oxygen levels in the blood, it can affect the timing of the heartbeat and cause palpitations.

7. Skin Elasticity

Skin elasticity is also related to hydration; if we’re dehydrated the skin becomes less supple. Doctors sometimes use a quick pinch test to check for dehydration because the rate at which the skin returns to normal can be a good indication of how hydrated a person is.

8. Constipation

Constipation occurs when the colon absorbs too much water, or when muscle contractions are slowed. When we’re dehydrated the colon tries to absorb more water from our food, which causes our stools to become hard and dry.

9. Dark Yellow Urine

When we’re dehydrated and blood pressure levels fall, the kidneys try to conserve water by concentrating urine, or by stopping production all together. As urine becomes more concentrated it turns darker until it reaches a dark yellow or amber color.

10. Dry Mouth and Swollen Tongue

While it may seem obvious that the mouth becomes dry when we’re thirsty, a little known accompanying symptom of dehydration is a slightly swollen tongue. These are likely the most common and quickest indicators of dehydrations, and should not be ignored.
