KENZEN LAUNCHES DATA DASHBOARD THAT ANALYZES SAFETY AND PRODUCTIVITY OF WORKERS IN HOT AND HUMID CONDITIONS
NEW YORK CITY (March 23, 2021) – Kenzen has launched a data and analytics dashboard, the latest component of its smart PPE connected worker solution. The dashboard captures workers’ core body temperature (the greatest predictor of heat stress and illness), productivity, and microclimates caused by clothing under hot and humid working conditions.
Environmental Health and Safety (EHS) managers and company leaders can now have a data-driven overview of work sites, both real time and retrospectively, to evaluate heat risk information by location and job role. The analysis consists of tens of thousands of data points collected per worker per day from the Kenzen wearable which tracks physiological factors including core temperature and heart rate. The Kenzen system uniquely enables companies to identify and address challenges and opportunities related to work in hot and humid conditions. The information allows them to manage risk and improve processes to keep workers safer and more productive.
Last year, Kenzen unveiled the monitoring device and its complimentary mobile app that alerts workers when they are at risk of heat stress and illness and when to stop work, rest, and return to work safely. The hardware and app work together to feed data to the real-time dashboard for supervisors to monitor their teams proactively and intervene when necessary.
Kenzen’s new analytics dashboard allows senior managers, who on average are responsible for 10 teams of 10 people each day, to dig deeper into the data and have a holistic view across worksites and teams. The dashboard provides insight into how various environments affect workers and uses the information to guide management in the implementation of changes to keep workers safer while optimizing productivity. Actionable feedback enables tailoring of work/rest schedules and identification of PPE clothing with the least impact on worker performance.
The complete Kenzen solution integrates the company’s commitment to personal data privacy; only workers can view the details of their personal health information and safety managers and other EHS leaders only see what’s necessary to keep the worker safe.
“The latest tool in the Kenzen connected worker solution comes just in time for a summer that’s expected to be one of the most extreme on record,” said Heidi Lehmann, Kenzen co-founder and chief commercial officer. Lehmann adds that, for every 10-degree Fahrenheit increase in temperature, there is a 393 percent increase in hospitalizations for heat exposure. “Now companies have the power to predict and prevent heat-related injuries and deaths and manage productivity at the same time.”
Founded in 2016, Kenzen is the premier physiological monitoring platform to keep workforces safe from heat, fatigue, and over exertion on the job while providing data driven insights to maintain productivity.

Utilities’ and contractors’ field crews must often work in extreme heat during the summer months. Here is how to recognize symptoms of heat stress.
You’ve likely experienced a hot day working in the heat. You’re hot, thirsty, tired, and sweaty, and the work that you’re used to doing feels even harder. But why?
Your body wants to maintain a really tight temperature range: ~3-4°F or 2-3°C. But even increasing your body temperature by 1-2°F can have a big impact on your body’s physiological responses. Your body temperature goes up when you are accumulating heat faster than you can get rid of it.
You can accumulate heat from the environment, like when it’s really hot and humid outside, or when you’re exercising or working really hard in the heat. When you’re working or exercising, your muscles produce heat as a byproduct of the movements you’re doing. In response to this increase in heat production, we increase blood flow to the skin (to move heat from the body core to the skin) and start sweating to get rid of body heat.
However, if you’re producing heat faster than you can get rid of it, your body temperature will go up. As your body temperature gets higher, you will sweat more too in order to try to get rid of more heat. The hitch is that the sweat must be evaporating off of you to cool you down and reduce your core body temperature (i.e. dripping sweat doesn’t cool you down). As you’re sweating more, you’re losing more body water.
Your blood is made up of ~50% water, and so when you lose this water through sweating, your blood volume goes down. This is a problem because you need blood to go to the working muscles in your body for energy. Your blood carries oxygen, which is essential for your muscles to create the energy they need to keep working. This also means that you have less blood going to the skin to get rid of heat. As a result, your heart (which pumps the blood) has to work even harder to get the same amount of blood to your working muscles and to the skin. This means that your heart rate will be higher when working in the heat vs. working in a comfortable environment.
The loss of water (and therefore blood volume) through sweating is one of the reasons staying hydrated is so important. By replacing the fluids you’re losing through sweating, you can help your heart rate to stay lower during your work in the heat. In turn, this will allow you to work harder in the heat–simply by staying hydrated.
If you’re not staying hydrated on the job, not only will you have a higher heart rate, but you will feel more fatigued, and are more likely to be in a bad mood (frustrated, angry, etc), and you might also experience some “fogginess” in your thinking. So make sure that you’re taking frequent breaks, drinking plenty of fluids, avoiding alcohol, and eating healthy foods.
Most importantly, if you start to experience any of the signs and symptoms of heat injury or illness, be sure to stop working right away and take a break. These are early warning signs that your temperature is getting too high and you need to slow down and take a break. Remember that heat illness can lead to exertional heat stroke and even death. Take any signs and symptoms seriously.
Monitoring your heart rate with smart PPE or a chest strap can help you to know if you might be dehydrated, because your heart rate will be higher than normal for the same workload. Make sure that you are staying aware of how you’re feeling throughout the day, and have a buddy to check in with and talk to so that you can make sure you are both doing okay on really hot, humid days.
Drink plenty of fluids, stay cool, and pay attention to your body and any warning signs it might be giving you to stay safe in the heat.
We’ve probably all been there: sweating it out in the heat, wishing we were in a cool lake or pool, and so we reach for that water bottle and pour the water on our head for some relief.
But does this actually cool you off or is this relief just temporary?
The answer: it depends on your conditions.
In a hot-dry environment (low humidity):
- Pouring water over your head can cool you off and lower your core body temperature, but the caveat to this is that you have to be in a place where the water you poured on your body can evaporate off of your skin and get rid of heat (remember, only sweat that evaporates off of your skin actually cools you off).
- A good breeze is also important to help wick the water off of your skin to cool you down.
And as you’ve probably guessed, you’d also need to be wearing minimal clothing— like shorts & a t-shirt— as heavy clothing, like PPE, would just trap the water you poured on your body.
strong>In a hot-wet environment (high humidity):
- If your sweat is already dripping off of you and it’s really humid outside then pouring water over your head might make you feel better, but won’t help you cool down.
- Research has shown that pouring water over your head can make you feel cooler by reducing your skin temperatures and also reduce your perceived exertion (how hard you feel like you’re working) in the heat. However, it won’t improve your performance.
So, what’s the verdict on pouring water over your head?
Unless you’re wearing light clothing and working in a hot-dry environment where the water can evaporate off of your skin, it won’t help to cool you off. That being said, if it makes you feel better to pour cold water over your head and helps you get through the work day, it won’t hurt you, so go for it- just remember to keep an eye on the signs & symptoms of heat illness.
