Dehydration And What You Should Know


Each day, most of us are quietly dehydrated without even knowing it. Just think about it: throughout the workday is there ever a time that you start to feel really really sleepy? Well, dehydration is the #1 reason for afternoon fatigue, particularly during the summer. Let’s take a look at some aid for dehydration.

What Causes Dehydration?

A lot of people think that not drinking enough water is the reason of dehydration. Yet, not drinking enough water is only part of why a person could be dehydrated.

Our bodies are made up of 70% water. Each day we commonly lose a portion of that water from urination, bowel movements, sweat, and tears

The problem comes when we don’t take in the water we are losing, leading our body’s water percentage to decrease

The Ohio State University Wexner Medical Center recommends that when we lose water, we also lose salt and electrolytes in our systems that are necessary to our body. This combination of the loss of salt and water leads to dehydration.

How do you recognize dehydration? What are the signs and symptoms?

For Adults, there are many symptoms like:

  • Thirst/dry mouth
  • Dark urine or urinating less frequently (maybe one or two times a day)
  • Sleepiness
  • Constipation
  • Little to no tears when crying
  • Dry skin
  • Headache
  • Dizziness
  • Lightheadedness
  • Muscle cramps (especially during exercise)

For Children:

  • Lack of urine or wet diapers for 6-8 hours (lack of urine for 12 hours in older children)
  • Little to no tears when crying
  • Eyes look sunken into head
  • Soft spot on baby’s head looks sunken
  • Irritability, less active
  • Fatigue or dizziness in older children 

What should you do if you are dehydrated?

Rehydrate! Mild dehydration can be simply treated at home by drinking more water.

Drink water or sports drinks (sports drinks can supply electrolytes, salt lost through sweating and other water loss).

According to the Institute of Medicine, Men is recommended to drink 13 glasses of water a day (about 3 liters) and women should drink about 9 glasses a day (about 2.2 liters)

Many of us have known the 8×8 rule: drink eight, 8 oz. glasses of water a day to stay hydrated. Nevertheless, this information isn’t supported by hard scientific evidence. But it is close to the suggested amount of water we should drink and is simple to remember. That’s why it sticks around, but we should be drinking more water than the 8×8.

When should you seek medication for dehydration?

In severe cases, seek medical attention for dehydration. Signs of severe dehydration are as follows:

  • Extreme thirst
  • Lack of sweat when active
  • Sunken eyes
  • Shriveled or dry skin
  • Rapid breathing
  • Fever
  • Extremely dry mouth, skin, and mucous membranes (nose, mouth, throat, eyelids, ears )
  • Low blood pressure
  • Rapid heartbeat
  • Delirium or unconsciousness (in extreme cases)
  • Still, even easy dehydration can lead to big problems such as mood changes, memory impairment, headaches, and constipation. Be careful with these changes as well.

How can you avoid getting into the dehydration risk zone in the first place?

Right when you get up every morning, drink a glass of water.

Another glass of water before every meal.

Also, have a bottle of water on your desk at work (or in your bag at school). This will help you stay hydrated.
