As all body functions depend on water, proper hydration is the key to overall health. And in order to stay hydrated, it’s important to drink lots of fluids and eat foods high in water.
However, there are conditions when your body loses more water than usual. Some of these include hard physical activity, excessive sweating, diarrhea, vomiting, diabetes and frequent urination.
Dehydration can have a negative impact on your body function as it leads to an electrolyte imbalance.
Unfortunately, dehydration can often go unnoticed as most people are unaware of this condition. Knowing how to identify the symptoms of dehydration can help you take timely action and protect your health.
These are the top 10 signs that you are water deficient:
- Headaches and dizziness
These are some of the first symptoms of dehydration because in this case, there’s a reduced amount of fluid surrounding your brain. This fluid is particularly important as it acts as a buffer protecting the brain from mild knocks.
Along with migraines, dehydration leads to irritating headaches because it decreases the flow of oxygen and blood to the brain.
According to a 2010 report published in the Handbook of Clinical Neurology, dehydration is one of possible causes of migraines and severe headaches.
A glass can water, as opposed to pills, can be equally beneficial when dealing with a headache caused by dehydration.
- Brain fog or poor concentration
Not only does dehydration trigger headaches, but it also reduces brain function. As the human brain is almost 90% water, water deficiency in the brain can have a negative impact on your decision making skills, memory and mood.
Dehydration often manifests through symptoms of brain fog including forgetfulness and difficulty focusing, thinking and communicating.
According to a 2013 study published in Clinical Autonomic Research, dehydration is one of the most frequently reported causes of brain fog together with fatigue, sleep deficiency, and prolonged standing.
A different study of 2011, published in the British Journal of Nutrition, revealed that dehydration can also lead to mood swings.
- Bad breath and dry mouth
In a state of dehydration, your body produces less saliva, which has antibacterial properties. This leads to bad breath because there’s bacteria proliferation in the oral cavity.
Another symptom is a dry mouth because water is a lubricant that keeps the mucus membranes in the throat hydrated, thus preventing dry mouth.
- Constipation and other digestive issues
Water hydrates all cells and tissues in the body, which also applies to the digestive system. In fact, water keeps the gastro-intestinal tract supple and clean. Also, it stimulates regular your bowel movements and prevents constipation.
Constipation is a common symptom of dehydration leading to hardened stool due to excessive loss of fluid. Diarrhea and vomiting often lead to dehydration. This condition can even cause acid reflux and indigestion.
A 2003 study published in the European Journal of Clinical Nutrition reveals that proper hydration is the key to prevent constipation and maintain proper body function.
- Sudden food cravings
People commonly mistake their need for water with food cravings. In fact, your body sends false signals to your brain that you are hungry, when actually you are thirsty. So, the next time you get a sudden food craving, drink a glass of water first before reaching for a snack.
Another reason why you feel hungry when actually thirsty is the fact your body is craving salty food when you’re experiencing loss of water and electrolytes. You can easily address this issue by drinking a sports drink that contains sodium, or by mixing some fresh lemon juice, a glass of water and a teaspoon of salt.
When there’s glycogen production difficulty in your body, you also experience sweet cravings. In this case, reach for fruits like watermelon, papaya or berries, which are not only sweet, but also high in water.
- Reduced need for urination and change in urine color
If you don’t have the need to urinate every few hours, your body may be experiencing dehydration. When you are getting enough water, you should be going to the toilet about 4-7 times a day. If, however, you don’t, the toxin levels in your body increase.
Another thing that dehydration does is change the color of your urine, which is an important indicator of how well hydrated you are. When your body is well-hydrated, the color of your urine is clear or light, whereas dark yellow or amber-colored urine is a clear sign of dehydration.
- Fatigue and lethargy
Dehydration also makes you feel fatigued and lethargic. As your brain is lacking water, this causes low blood pressure and inadequate oxygen supply throughout your body. This in turn leads to sleepiness, fatigue and a lethargic feeling.
Dehydration also negatively affects the transport of essential nutrients to every cell in the body. In fact, your body works very hard to sustain this, spending more energy than usual, thus making you feel constantly tired.
Keeping hydrated is the easiest way to stay alert and full of energy.
- Joint and muscle pain
Your joints and cartilage are made of 80% water, so whenever you’re lacking this fluid, it increases friction between your bones, which leads to joint pain. In contrast, when your body is well-hydrated, your joints can handle sudden movements, such as running, jumping or falling, without any pain.
Water deficiency also results in muscle spasms and cramps.
