10 Warning Signs That Your Body Is Lacking Water
Thirst may be annoying at times, but it should never go ignored.
Water actually makes up over two-thirds of the healthy human body.
It lubricates the joints and eyes, aids digestion, flushes out waste and toxins, and keeps the skin healthy (1).
That’s why you should always make sure to drink water throughout the day and before and after meals.
Many people don’t realize how much water they lose everyday and end up chronically dehydrated (2).
Diabetics, burn victims and athletes are at a higher risk of dehydration than the average person.
Here’s a list of warning signs of dehydration that you should pay attention to (3):
1. Heart Palpitations
When the normal water content of your body is reduced, it upsets the balance of minerals (salts and sugar) in your body, which affects the way it functions (1).
Heart palpitations typically occur when there is low potassium and low sugar levels in the blood (4). This can cause from premature contractions of the heart’s upper chambers (atria) or the lower chambers (ventricules) .
Low magnesium (through excessive sweating or diarrhea) may also lead to abnormal heart rhythm (4).
2. Bad Breath
Saliva protects your teeth from decay, disease and cavities by forming a protective barrier around them and helping clear food particles on and between your teeth (5).
When you become dehydrated, you do not produce as much saliva. The reduced cleaning action of the saliva allows bacteria to grow, causing bad breath (6).
Dry mouth also makes you more likely to develop rapid tooth decay and gum (periodontal) disease (5).
3. Food Cravings
“When you’re dehydrated, it can be difficult for some nutrients and organs like the liver which use water to release some glycogens and other components of your energy stores, so you can actually get cravings for food,” says John Higgins, MD, associate professor of cardiovascular medicine at the University of Texas in Houston, and chief of cardiology at Lyndon B. Johnson (7).
“While you can crave anything from chocolate to a salty snack, cravings for sweets are more common because your body may be experiencing difficulty with glycogen production,” he says.
Instead of junk food, reach for water-dense foods, try fruits like watermelon, kiwi and peaches. You may also find that vegetables like cucumber and tomatoes also satisfy your craving.
4. Painful Joints and Muscles
The cartilage in your joints is made up of roughly 65 to 80% water. When the joints aren’t properly hydrated, it can cause the bones they connect to grind. This causes pain and inflammation (8).
Low magnesium from dehydration can also cause muscles cramps and pain in the leg muscles (4). Eat dark leafy greens and avocado to replenish both your water and mineral levels.
The brain sits inside a fluid sack that keeps it from bumping against the skull. This ensures that your brain isn’t damaged every time you walk or run.
If the fluid in this sack is reduced, your brain can begin to push against your skull. This is one of the most common causes of headaches (7).
Dehydration also decreases blood supply to the brain, meaning less oxygen and glucose, which can also trigger a headache (9).
