How to test for hydration in the workplace?
Ensuring that workers are properly hydrated is essential for maintaining their health and safety, particularly in industries where physical labor is required. Dehydration can have serious consequences, including heat exhaustion, heatstroke, and even death. In this article, we'll provide a comprehensive analysis of the key factors that impact dehydration and explore the importance of testing workers for dehydration to avoid health and safety issues.
Increased humidity, hot temperatures, sunburn, and excessive physical work outdoors are all factors that can lead to dehydration. When the body is exposed to high temperatures and humidity, it loses fluids through sweating in an effort to cool down. Sunburn can also contribute to dehydration, as it can make it more difficult for the body to regulate temperature and maintain hydration levels. Excessive physical work outdoors can cause the body to lose fluids and electrolytes quickly, leading to dehydration.
To avoid these issues, it's important to test workers for dehydration regularly. One method of testing is by using a urine color chart, which can indicate the level of hydration in the body.
When testing urine, color is the clear indicator of hydration levels. The following are the most common colors and what they may indicate:
Clear or colorless urine
Clear or completely colorless urine may be a sign that a person is overhydrated or drinking too much water. Drinking water in excessive quantities is not good, doing this can alter the balance of electrolytes in the bloodstream. Taking “water pills” or diuretics increases the urine output. Workers taking these types of medications may find that they urinate more frequently and therefore release more toxins, minerals and electrolytes, making their urine more diluted and finally clear. Diabetes can also be a factor that leads people to urinate more frequently and feel thirsty more often. This leads to drinking more water which can cause clear urine.
Pale or transparent yellow urine
Pale or a very light yellow shade of urine is typically a sign that the person is hydrated and drinking an appropriate amount of water.
Dark Yellow or amber color urine
A dark shade of yellow may indicate that a worker is mildly dehydrated. This typically means that they need to drink more water and replenish electrolytes to avoid potential dehydration.
The Centers for Disease Control and Prevention (CDC) state that there is no recommendation regarding how much water a person should drink throughout each day. However, if possible, a worker should aim to drink 64 ounces or 8 glasses of water per day. This amount will depend on the activity being performed and the working and weather conditions. A worker performing arduous physical activity under the sun, like a roofer for example, needs to have access to water but should also drink electrolyte replenishment drinks like Gatorade, Sqwincher or Sword. Another great option would be to take a break in a shaded area and enjoy a freezer pop like Sqwincher Sqweeze, Myhy Freezies or Shield Freeze Pops, which are not only refreshing, but could also help lower body temperature while providing all the necessary electrolytes lost in sweat.
Orange Urine
Light orange urine may be an indicator that the team member is slightly dehydrated, so they may need to immediately increase their fluid intake. Taking certain vitamins, such as riboflavin, can make urine turn a vibrant yellow or orange color. The following medications may also turn urine orange:
- Phenazopyridine
- Sulfasalazine, an anti-inflammatory drug
- Certain laxatives that contain senna
- Most chemotherapy drugs
Dark Orange or brown urine
According to the Urology Care Foundation, dark orange or brown urine can occur if a person is not producing enough urine. This makes the urine produced more concentrated and darker in color.
This specific color may be due to dehydration , strenuous activity, or being exposed to a hot climate. Drinking more water and replacing electrolytes may help dilute urine, and will also make it lighter in color.
Dark urine can also be a sign of a problem with the liver. A liver problem can cause the body to excrete increased levels of bilirubin, which is a pigment present in bile. High levels of bilirubin can be an indicator of liver inflammation or other medical conditions associated with the liver.
Dark brown or black urine
Dark urine may be an indication of a serious medical condition like the following:
- Liver disease: Dark brown urine may be a sign of liver disease
- Rhabdomyolysis: Dark brown, dark red, or tea-colored urine is a potential sign of Rhabdomyolysis, which is a serious condition that occurs from muscle tissue death. People with this condition need immediate medical treatment.
- Alkaptonuria: Also called black urine disease, this is a rare inherited condition that stops the body from breaking down two types of amino acids.
Pink or red urine
This is a tricky one. A worker's urine may be pink or red after eating certain foods such as blackberries, rhubarb or beetroot.
Blood in the urine, or hematuria , may also be a cause of blood turning pink or red. This may be due to a urinary tract infection (UTI),prostate infection, or kidney stones. In some cases, it may be a sign of kidney disease or cancer.
When to seek Medical assistance?
A person may wish to contact a doctor if they experience a change in their urine that is not due to eating colored foods or taking medication. This is particularly important if the change lasts more than 1–2 days.
Frothy or foamy urine may be a sign of a kidney problem. Excessive bubbles in urine, which can be hard to flush, can be a sign of protein in urine, which may indicate kidney disease.
People will also need to contact a doctor if they have:
- cloudy or foul-smelling urine, as this may be a sign of a UTI or other infection
- an urgent or frequent need to urinate, particularly with increased thirst
- pain or a burning sensation when urinating
- urine that remains dark even when a person is sufficiently hydrated
- bloody urine
What is another way to check the hydration level?
Another method is to pinch the back of the hand and check for skin elasticity. If the skin does not return to its normal position immediately, it may indicate dehydration. When the body is properly hydrated, the skin is more elastic as it has sufficient levels of water in the cells. When the body is dehydrated, the skin’s elasticity decreases and it can be easily tested with this method.
In addition to testing for dehydration, it's important to provide workers with access to hydration and electrolyte replenishment drinks. Choosing the right ingredients is key to ensuring that workers get the necessary amount of electrolytes to stay hydrated. Look for products that contain electrolytes such as sodium, potassium, and magnesium, as well as carbohydrates to help provide energy.
Treatment for dehydrated workers can be very costly, especially if they need medical attention to treat heat stress, heat exhaustion, or heatstroke. Hydrating your workers to prevent these issues is way more cost effective as it ensures they are healthy and performing at their best.
To help control costs, Hydration Depot offers discounts like free shipping on bulk orders and hydration bundles. Many products, such as Gatorade powder, Gatorade bottles, Sqwincher sqweeze freezer pops, and bottled water, are available in bulk sizes that offer significant savings compared to buying individual servings. Wholesale Gatorade is another option for those looking to buy hydration products in bulk. Buying hydration products in bulk can be a great way to save money and ensure that workers have access to hydration options throughout the day
In conclusion, testing workers for dehydration and providing access to hydration and electrolyte replenishment drinks is essential for maintaining their health and safety. It's important to consider factors such as increased humidity, hot temperatures, sunburn, and excessive physical work outdoors when making decisions about hydration products. By choosing the right ingredients and buying in bulk, you can ensure that workers have access to the hydration they need to stay healthy and safe on the job.
