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.

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.

Most heat-related deaths occur in the first few days on the job. Heat acclimatization can help prevent this.
A study of OSHA citations issued between 2012 and 2013 revealed 20 cases of heat-related illness or death of workers [Arbury et al. 2014]. In most of these cases, employers had no program to prevent heat illness, or programs were deficient; and acclimatization was the program element most commonly missing and most clearly associated with worker death.
How Do You Acclimatize to the Heat?
You might have already heard about heat acclimatization, but what is it and why does it actually make your job easier?
Heat acclimatization is a process where your body undergoes physiological changes that allow it better handle the heat— which means that your performance in the heat will improve and you are less likely to suffer from heat-related problems (e.g., heat cramps).
For heat acclimatization to occur, you typically have to increase your core body temperature by 1°C (~1.8°F) for at least 1 hour, repeatedly each day, for 5-14 days in a row (each person will take a different amount of time to acclimatize to the heat).
Physiological Changes that Occur with Heat Acclimatization
After your body is acclimatized to the heat, you will notice lots of different changes.
- Sweating: You will start to sweat sooner (at a lower core body temperature) and you will sweat more. This is important because it allows your body to cool off (through evaporative heat loss), which means that your body temperature will stay lower for the same work rate. (See a refresher on heat loss through sweating here). You may also notice that your sweat becomes less salty after you’ve been working in the heat for a while; this is because your body becomes more efficient at reabsorbing the salt in your sweat, which helps you stay better hydrated in the heat.
- Heart rate: Your heart rate at rest and during work (or exercise) will be lower after heat acclimatization. This is because you get an increase in plasma volume (the water in your blood) with heat acclimatization, which means that with each heart beat, you can now pump more blood (to get more oxygen to the working muscles). As a result, your heart rate will be lower for the same work rate. This means that you can work for longer in the heat without getting tired. (See a refresher here on heart rate changes with heat stress).
- Core and skin temperatures: Due to the improvements in your sweating (and improved ability to get rid of heat), your core and skin temperatures will be lower at rest and during work or exercise (for the same work rate). This, combined with a lower heart rate, means that after heat acclimatization, you can work harder for longer periods of time before needing to take a break because your body is staying cooler.
