The Dangers of On-the-Job Dehydration
Everyone knows staying hydrated is important. But not everyone really understands what’s in store for them if they let dehydration take over. In this article, we’ll clear things up by going over what dehydration does to your body. And we’ll end with some practical tips for staying hydrated throughout the workday. Fluids are essential for regulating body temperature, lubricating joints and eyes, facilitating proper digestion, and removing toxins from the body. It shouldn’t come as a surprise, then, that effects of dehydration are a lot worse than just feeling a bit parched.
Dehydration happens when your body uses or loses more fluid than it takes in. When it happens, your body starts running on empty and can’t carry out its normal functions. Lost fluids must be replaced to avoid an imbalance of salts and sugar in the body, which can affect performance.
The average adult has about 2.6 million sweat glands, which activate when the brain determines that the body must be cooled down. This takes a real toll on those whose jobs involve physical labor. Estimates suggest that workers who wear heavy protective clothing can lose as much as 2.25 liters of fluid every hour, NIOSH and the Centers for Disease Control recommend that a moderately active worker drinks one cup every 15 minutes, whether they feel thirsty or not.

There are a handful of key factors that contribute to dehydration:
• Physical activity
• Health conditions
Strenuous work in the sun, heat, and humidity causes you to swear and quickly depletes your body’s fluids. But that doesn’t mean you’re safe in the winter: the same thing can happen in extreme cold. Dehydration can also be a constant risk for people who work indoors. Many factory, restaurant kitchen, and laundry service workers spend their days in hot environments.
Your hydration level is also affected by:
• Frequent urination (due to altitude or illness)
• Quicker breathing, which uses up more body fluids
• Vomiting and diarrhea
• Alcohol, caffeine, and sugary drinks
Symptoms of Dehydration
Okay, so you’re sweating it out throughout your work day but you go hours without taking a drink. What happens next?
The obvious symptoms are thirst and excessive sweating, but the more subtle signs of mild to moderate dehydration include:
• Dry, sticky mouth
• Dry skin
• Dizziness or light-headedness
• Less frequent urination
• Dark yellow urine (pale yellow indicates proper hydration levels)
• Muscle cramps
If you suspect that dehydration is starting to set in, there’s a simple way to check: the pinch test. Dehydrations affects skin turgor (its ability to change shape and return to normal). With your thumb and index finger, pinch the skin on the back of your hand and hold it for a few seconds. If it doesn’t bounce back right away and takes time to return to its normal position, you’re likely dehydrated and need to replenish your fluids.
If not addressed, this will progress into severe dehydration, the symptoms of which include:
• Irritability and confusion
• Sunken eyes
• Low blood pressure
• Rapid heartbeat
• Rapid breathing
• Little to no urination
• Delirium or unconsciousness (in serious cases)
Tips to Stay Safe
The easiest way to prevent dehydration is to ensure you are consistently taking in fluids throughout the day, even if you don’t feel thirsty. While the recommended daily intake varies depending on age, climate, and physical activity level, workers should aim to drink about one cup of fluids every 15 to 20 minutes to replace what is being lost.
Here are some other helpful tips to help you maintain good hydration:
• Avoid caffeine and sugary drinks. These are diuretics and will increase urine output, which can cause greater dehydration.
• Come prepared for the conditions. If you’re anticipating high temperatures, humidity, heavy PPE, and difficult work, come prepared with plenty of hydrating fluids.
• Wear breathable, light-colored clothing. This allows sweat to evaporate and keep your body temperature low. If your clothes become saturated with sweat, change into dry ones as soon as possible.
• Eat plenty of fruits and vegetables. These are great sources of electrolytes and fluids. Opt for fruits with high water content, like melon, pear, pineapple, and grapefruit. Bananas are high in potassium and are perfect for quickly refueling.
• Monitor your urine. If you’re properly hydrated, you should have clear to light yellow urine. Dark indicates dehydration and you should increase your fluid intake immediately.
If you or a co-worker exhibits signs of dehydration, call for medical assistance immediately and move to a cool place.
How Employers Can Help
Employers must provide and maintain a safe working environment for all employees. And that includes taking steps to prevent dehydration. Moreover, numerous studies show that hydration levels have a strong effect on workplace productivity. A one percent drop in hydration is enough to cause a 12 percent drop in productivity. At three to four percent dehydration, productivity plunges by an astounding 25-50 percent.
With that in mind, here are some tips employers can follow to promote proper hydration in the workplace:
• Provide hydration education. Teach workers to recognize the signs and symptoms of dehydration and how to combat it. Reinforce the message with ongoing training and visual reminders, like posters.
• Keep fluids accessible and available. Making drinks easily accessible encourages employees to stay on top of hydration.
• Offer employee incentives. Reusable water bottles or hydration packs may encourage employees to keep fluids with them at all times and remind them to drink regularly.
• Choose the right PPE. Ensure all protective gear is breathable to allow sweat to evaporate and help workers remain cool.
• Use the buddy system. In addition to a manager looking out for employees, they can keep an eye on each other.
• Have an emergency plan. A plan makes it simple and efficient to get first aid or medical treatment for affected workers. Ensure everyone knows his or her role to avoid confusion in an emergency situation.
The best way to ensure you’re functioning at your best is to get to know your body and to listen to it. Pay attention to signs that you may be getting dehydrated and make sure you’re taking in fluids at regular intervals throughout the day. Your health and well-being truly depend on it.
