Dehydration occurs when your body loses more fluid than you take in.
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.
Water 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.
Some of the early warning signs of dehydration include:
1. Thirst
Thirst, a signal from your body to replace fluids, typically happens when your body has lost between 1 to 2 percent of its total water supply. However, your body may need more water before the thirst signal kicks in, according to Mercola.
2. Dry skin
Someone who is severely dehydrated may not sweat. In addition, dehydration may lead to dry, cracking skin and flushing, according to Everyday Health. The next time your slather lotion on those dry hands, make sure to grab a glass of water too.
3. Cramping
Low fluids in your car can cause the engine to seize. The same thing can occur in your body if it lacks enough lubrication: When muscles start to heat up, you may get some very painful cramps. Drink a glass of water to help reduce cramping after a workout session. According to Everyday Health, “Changes in the electrolytes, changes in the sodium and potassium can lead to muscle cramping as well.”
4. Headaches
Before you reach for the aspirin, try swigging a cup of cool water. Your headaches could be a sign of dehydration. Without enough water the fluid sack surrounding your brain may become depleted, causing your brain to put pressure on parts of your skull. Drink up and keep your head healthy, according to Everyday Health.
5. Sweet-tooth temptation
Your body needs water to release certain nutrients, including glycogen. If you are dehydrated, your body may tell you that you need sugar, which often presents itself as cravings for chocolate and other unhealthy goodies. When you get that craving, grab some fruit instead. High in natural sugars and water, fruit will help ease your cravings and get your body’s water levels back up to normal, according to Everyday Health.
Dehydration is often the result of illness (especially vomiting and diarrhea), sweating, diabetes and frequent urination (often a side effect of medications or alcohol), according to Mercola. A simple way to make sure you are drinking enough water is to drink enough that your urine is light yellow or clear when you go to the bathroom. If your urine is dark yellow, you need more water in your system.
