10 Unusual Signs of Dehydration You Should Know About

Dehydration is a condition that occurs when your body loses more fluids than it takes in. Most people are aware of the common signs of dehydration, such as thirst, dry mouth, and dark urine. However, there are several lesser-known symptoms that can indicate dehydration.

In this blog article, we will explore 10 unusual signs of dehydration that you should be aware of.

10 Signs of Dehydration You Need To know

Signs of Dehydration
Signs of Dehydration

Fatigue and Lethargy

Feeling unusually tired and lacking energy can be a sign of dehydration. When your body is dehydrated, it works harder to function properly, leading to fatigue and lethargy. If you find yourself constantly feeling tired even after a good night’s sleep, it may be worth considering if dehydration is the cause.

Dizziness and lightheadedness

Dehydration can cause a drop in blood pressure, leading to dizziness and lightheadedness. If you frequently experience these symptoms, especially when standing up or moving quickly, it could be a sign that you need to hydrate yourself.

Muscle Cramps

Muscle cramps, especially in the legs, can be a surprising sign of dehydration. When your body lacks fluids, it affects the balance of electrolytes, such as sodium and potassium, which are crucial for normal muscle function. If you often suffer from muscle cramps without any apparent reason, dehydration could be the underlying cause.

Bad Breath

An unusual sign of dehydration is bad breath. When your body doesn’t have enough water, it reduces saliva production, leading to dry mouth. The lack of saliva allows bacteria to thrive, resulting in bad breath. If you find yourself frequently reaching for mints or mouthwash, consider increasing your water intake to combat dehydration.

Dry Skin

Dehydration can also manifest itself through dry and flaky skin. Without adequate hydration, your skin loses its natural moisture, leading to a lack of elasticity and a rough texture. If you notice your skin becoming dry and irritated, it could be a sign that you need to drink more water.


Headaches are a common symptom of dehydration, but they can sometimes be unusual in nature. Dehydration headaches are often described as a dull, persistent ache, rather than a sharp or throbbing pain. If you frequently experience headaches, especially when combined with other dehydration symptoms, it is crucial to rehydrate your body.

Dark Circles under the Eyes

While dark circles under the eyes are commonly associated with lack of sleep or stress, they can also be a sign of dehydration. When your body is dehydrated, it tries to conserve water, resulting in blood vessel constriction. This can cause the blood vessels under your eyes to appear more prominent, giving the illusion of dark circles.

Decreased Urination

A decrease in urine output is a clear sign of dehydration. If you notice that you are urinating less frequently or in smaller amounts than usual, it may indicate that you are not drinking enough fluids. Monitoring your urine color can also provide insights into your hydration levels; dark-colored urine is a sign of dehydration.

Sugar Cravings

Unusual sugar cravings can be a surprising sign of dehydration. When your body is dehydrated, it sometimes confuses thirst with hunger, leading to cravings for sugary foods. If you find yourself constantly reaching for sweets or craving sugary snacks, it might be worth considering if dehydration is the underlying cause.

Decreased Cognitive Function

Dehydration can have a negative impact on cognitive function. Studies have shown that even mild dehydration can impair mental performance, including memory, attention, and concentration. If you find it difficult to focus or experience brain fog, it could be a result of dehydration.

Are You Dehydrated, or Could It Be Something Else?

Being thirsty indicates that you are already dehydrated. However, not feeling thirsty doesn’t necessarily mean that you are properly hydrated. Here are two alternative methods to assess your hydration levels.

Perform the skin test. Pinch up some skin on the back of your hand using two fingers and release it. The skin should quickly return to its normal position within a couple of seconds. If the skin takes longer to return to normal, it could indicate dehydration, as stated by MedlinePlus.

Examine your urine. If you are adequately hydrated, your urine should be mostly clear with a slight yellowish tinge (similar to the color of light lemonade). Darker shades of yellow or orange are signs to be cautious of, according to UC San Diego Health. If your urine appears dark, it is advisable to consume fluids. (Conversely, clear or transparent urine might indicate excessive water intake.)

The amount of fluid you need to stay hydrated varies based on factors such as age, gender, pregnancy or breastfeeding, and medical conditions. The National Academies of Sciences, Engineering, and Medicine recommends 2.7 liters of water per day for women and 3.7 liters per day for men.

Here are some tips to help you meet your fluid needs and prevent dehydration:

  1. Keep a water bottle with you at all times for easy access. This will help you develop the habit of sipping water throughout the day.
  2. If you find plain water boring, add a splash of fruit juice or chunks of fresh or frozen fruit to make it more enjoyable. You can also try flavored calorie-free seltzers.
  3. Opt for sugar-free herbal tea or coffee, which can also count towards your daily fluid intake. Unsweetened teas come in various flavors, and coffee can hydrate you similarly to water when consumed in moderation.
  4. Replace packaged snacks with hydrating options like fresh or frozen fruit, yogurt, smoothies, celery with peanut butter, and cut veggies with hummus.
  5. Include plenty of fruits and vegetables in your meals, as they have high water content. Aim to make half of your plate consist of produce, such as cantaloupe, strawberries, watermelon, cucumber, lettuce, zucchini, tomatoes, and bell peppers.
  6. Drink water while eating to slow down your pace and stay hydrated. This may also aid in weight loss, as shown in a study where participants who drank water before meals lost weight.

Remember to consume caffeinated beverages in moderation and limit your intake to 400 milligrams per day. Symptoms like upset stomach, frequent urination, and insomnia may indicate excessive coffee consumption.

Preventing Dehydration in Older Adults: A Final Reminder

According to the National Council on Aging (NCOA), older adults face a higher risk of dehydration due to various factors. Aging can lead to a reduced sense of thirst, resulting in a decrease in daily water intake. Additionally, certain medications like diuretics may contribute to chronic dehydration in older individuals. Difficulties in accessing water or forgetfulness due to health conditions like dementia can also lead to dehydration. The consequences of chronic dehydration in older adults may include confusion, low blood pressure, dizziness, and constipation.

If you have an elderly family member with limited mobility or cognitive issues, it is important to monitor them for signs of dehydration. You can also request their caregivers to do the same and ensure that they consume an adequate amount of water. Furthermore, it is crucial to remember that the human body is primarily composed of water, accounting for at least 60 percent, as highlighted by the U.S. Geological Society. Therefore, maintaining a healthy water balance is essential for your overall well-being. Stay hydrated!
