How long does it take to recover from dehydration?

The time it takes to recover from dehydration depends on how dehydrated you are

 hydration I.V.

If you are severely dehydrated, it’s likely that you will be hospitalized and put on intravenous hydration for up to 24 hours to recover from dehydration, or until you’re able to drink oral rehydration fluids yourself.[1] When you’re severely dehydrated, you need to put back a LOT of fluid, and it needs to be balanced with the nutrients that your body usually contains.

If you were to suddenly put a lot of water back into your body after being severely dehydrated, it might cause your body to go into a form of shock, so you need to pace yourself[2]

At less severe dehydration levels that are still serious, it’s possible that you’ll only be drinking oral rehydration fluids. CDC guidelines for those suffering from dehydration through Cholera recommend drinking up to 1 liter of ORS fluid per hour for an adult, and children 20ml / kg of body weight.

Dehydration Symptoms: How to tell if you're dehydrated

You are dehydrated when you lose more fluids from your body than are taken in, for example when you have a stomach flu mixed with diarrhea or if you consume alcohol. Dehydration prevents the body from functioning normally, and as a result you can experience symptoms of dehydration. Symptoms of dehydration include:

- Dry mouth

- Dry skin

- Light-headedness

- Urinating less frequently 

- Fatigue

- Sluggishness

- Muscle cramps

- Changes in blood pressure

- Changes in heart rate

- Changes in body temperature

There are different levels of dehydration: mild, moderate and severe dehydration and many more signs that indicate you are dehydrated. If you are experiencing severe symptoms, we recommend seeking medical care immediately.


Is your routine dehydrating?

Some of us have more dehydrating routines than others, take our quiz to find out if you are meeting your hydration needs daily.






How long does dehydration last?

If you don’t treat dehydration by drinking water and in some cases taking on electrolytes in the right quantities, your dehydration will last indefinitely.  

If it progresses for long enough, you can die from dehydration. Most of us know this - you can go weeks without food, but only days without water. New York Times has reported results of a study that showed that 75% of Americans were chronically dehydrated. 

This meant that they were not meeting their daily requirement for water intake, and were staying in a dehydrated state for long periods of time! In that scenario, recovering from dehydration requires a complete overhaul to your routine, to ensure you're making it a daily habit to consume enough water.


So what is Hydrant? 

We made Hydrant to be an effective way to recover from dehydration quickly, based on World Health Organization guidelines for oral rehydration solutions. ORS have up to 3x the electrolytes of traditional sports drinks and contain only 6 grams of sugar. 

Drinking enough water each day can be hard for any number of reasons and using Hydrant makes hydration easier. Our oral rehydration solution contains electrolytes like sodium, potassium and magnesium that mimic your body's natural electrolyte makeup. When you lose water from your body, most of the time you also lose electrolytes. If you just replace the water, but not the electrolytes, you further imbalance your body.  To perform at your best throughout the day, it’s best to quickly replenish your body, using a solution that mirrors your biological electrolyte and water balances.
